1# Billing operations: costs, margin and prices
2
3How g1t checks what it charges against what Cloudflare charges it, keeps
4prices at cost plus 20%, and tells staff when the margin slips. Internal.
5Code: `services/billing/src/costs.rs` (reading the bill), `cycle.rs`
6(Cloudflare's billing cycle, list prices and included amounts), `margin.rs`
7(reconciliation, drift, alerts), `pricing.rs` (versions, proposals,
8notice), `keeper.rs` (sandbox and Workers for Platforms measurements),
9`budget.rs` (what g1t pays for itself, and its caps; see
10[Spend caps](#spend-caps)).
11Page: sudo **Costs & margin** (`/costs`).
12
13Several Cloudflare products g1t runs on are new. Artifacts bills
14"operations" from 2026-10-14 without defining them (see
15[ARTIFACTS.md](ARTIFACTS.md), M1). So nothing here hard-codes a product
16list or a unit: every line Cloudflare bills is kept, and how a line maps
17to what g1t sells is data you change from sudo, without a deploy.
18
19## Data sources
20
21| Source | What | Where it lands |
22| --- | --- | --- |
23| Billable usage, `GET /accounts/{account}/billable-usage?from=&to=` | One row per service per day in FOCUS columns: `ServiceFamilyName`, `ServiceName`, `ChargePeriodStart`, `ConsumedQuantity` (else `PricingQuantity`), `ContractedCost` / `BilledCost` / `EffectiveCost`. Every page is read (`result_info`: `cursor`, else `total_pages`), over whole billing cycles (see [The billing cycle](#the-billing-cycle)). Every product g1t uses appears here once it is used: Workers, Workers for Platforms, D1, KV, R2, Queues, Containers, Durable Objects, Artifacts, Browser Rendering, Workers AI, Vectorize, Cloudflare for SaaS, Email. While a cycle is open its rows carry no cost; `ListCost` is never taken, since it is before the included amounts. | `cost_lines`, source `billable_usage`: `quantity` (consumed), `billed_usd` (Cloudflare's own cost), `billable_quantity` and `cost_usd` (over the cycle), `basis`; the read itself in `cost_reads` |
24| GraphQL `artifactsEventsAdaptiveGroups` | Artifacts' own count by `date`, `eventType` and `repositoryName`. Operations are `create`, `fork`, `push`, `pull`, `delete`; errors (`rateLimited`, `serverError`, …) are kept but not counted. | `cost_lines`, source `artifacts_events`; per workspace (from the store key `<workspace>--<repo>`; a pull request's working copy, `pulls--<id>`, is its repository's workspace's, from repos' `pull_owners`) in `own_counts` as `cloudflare_git` |
25| GraphQL `aiGatewayRequestsAdaptiveGroups`, filtered to `AI_GATEWAY_ID` | What AI Gateway priced g1t's own provider traffic at, by `date`, `provider` and `model`: `count`, `sum.cost` (dollars), `sum.tokensIn`/`tokensOut`/`cacheReadTokens`/`cacheWriteTokens`; asked twice in one query, filtered `wholesale: 0` and `wholesale: 1`. `wholesale` is never a dimension: grouped by it, Cloudflare answers no rows and no error (until 2026-10-08 that left the gateway's side empty while it had logged $11.11). Read over its own window: the last 31 days until it has answered with a line, then the last few. Field names checked against Cloudflare's schema (introspection of `AccountAiGatewayRequestsAdaptiveGroups{Sum,Dimensions,Filter_InputObject}`). An adaptive (sampled) dataset: an estimate, close at g1t's volumes. Only g1t's hosted models go through this gateway: a workspace's own provider is called at its own address, never here. | `cost_lines`, source `ai_gateway`, product `ai_gateway_requests`: per day and model a line `<provider>_<model>` (requests, at the gateway's cost), and at no cost `…__tokens`, `…__cache_read_tokens`, `…__cache_write_tokens`; Cloudflare-billed (unified billing) requests are prefixed `wholesale__`. Mapped to `models` (migration 0036). A re-read day replaces all its gateway lines. |
26| The ledger | Every charge: its cost at the price book's cost, what it was charged at price, what paid for it. | read, never written |
27| `pending_usage` | Month-end meters (git, storage, scans, embeddings, the cache) as they stand. | snapshotted daily into `pending_days` |
28| `plan_payments` | The plan's $20. | read |
29| repos `git_operations` | Operations customers are charged for, per workspace, counted by repos through its `operation_mapping`. | `own_counts` meter `git_operations` |
30| Subscriptions, `GET /accounts/{account}/subscriptions` | What g1t pays each month whatever it uses (Workers Paid, add-ons): each subscription that is paid, trialing or awaiting payment, at its price over its frequency; and `current_period_start` of the monthly one, the day every billing cycle starts. Not on the billable-usage bill. Read first in the daily run, with the bill's token; a failure is logged and the last read stays. | `cf_subscriptions` (one row; `cycle_start`) |
31| repos `artifacts_usage` | Every raw meter of the git store (`git.fetch`, `git.receive_pack`, `binding.*`, …) per day and workspace, with repos' `operation_mapping`. | `own_counts` meters `artifacts_<raw meter>`, and `cost_operations` (raw counts × the mapping's `cost_operations`: what g1t expects Cloudflare to bill) |
32
33A meter's slug is Cloudflare's name lower-cased with words joined by `_`
34and the "(First … included)" note dropped: `Workers for Platforms CPU ms
35(First 60M ms are included)` under `Workers` is product `workers`, meter
36`workers_for_platforms_cpu_ms`. Several rows of the same day and meter
37(regions, tiers) are added together before they are stored.
38
39## The billing cycle
40
41Cloudflare bills usage per billing cycle: a month from the day the
42account's subscription renews. g1t's account renews on the 28th, so a cycle
43runs from the 28th to the 27th (Sep 28 to Oct 27, 2026). Each meter's
44included amount ("first 30M are included") is the account's, once a cycle:
45not a day's, not a calendar month's, and not per product. Code:
46`services/billing/src/cycle.rs`.
47
48- **When a cycle starts**: `current_period_start` of the monthly
49 subscription, from the daily read of the subscriptions
50 (`cf_subscriptions.cycle_start`). Until that has worked,
51 `CLOUDFLARE_BILLING_DAY` on g1t-billing (`28`), else the 1st.
52- **What is read**: the whole current cycle, every run, and the cycle
53 before while it is in its first 4 days (Cloudflare posts a day a day or
54 two late and restates recent days) or when nothing has been read yet.
55 Every page of the answer. The days read replace what was kept for them.
56- **What a meter costs**: where Cloudflare put a cost on any of a meter's
57 lines in the cycle, that cost, line by line (`basis` `cloudflare`).
58 Otherwise the list price past the included amount (`basis` `list`), on
59 the days the cycle's running total passes it: a cycle that crosses the
60 included amount on the 7th has all of its cost on the 7th and after, as
61 on Cloudflare's Billable usage page. Meters priced per million
62 (requests, CPU ms, rows, operations) are billed in whole millions:
63 9.16M CPU ms past the included 30M is 10M, $0.20. A meter with no list
64 price is costed at $0 (`basis` `none`), and sudo lists it.
65- **List prices** (`cycle::LIST_PRICES`), each with its included amount
66 per cycle:
67
68 | Meter | Included | Price |
69 | --- | --- | --- |
70 | Workers standard requests | 10M | $0.30 per million |
71 | Workers CPU ms | 30M | $0.02 per million |
72 | Workers for Platforms requests | 20M | $0.30 per million |
73 | Workers for Platforms CPU ms | 60M | $0.02 per million |
74 | Workers for Platforms scripts | 1,000 | $0.02 each |
75 | Workers Logs events | 20M | $0.60 per million |
76 | D1 rows read / written | 25B / 50M | $0.001 / $1.00 per million |
77 | D1 storage | 5 GB-month | $0.75 per GB-month |
78 | KV reads / writes, lists, deletes | 10M / 1M each | $0.50 / $5.00 per million |
79 | KV storage | 1 GB | $0.50 per GB-month |
80 | R2 Class A / Class B operations | 1M / 10M | $4.50 / $0.36 per million |
81 | Durable Objects requests | 1M | $0.15 per million |
82 | Durable Objects duration | 400,000 GB-s | $12.50 per million GB-s |
83 | Durable Objects SQL rows read / written | 25B / 50M | $0.001 / $1.00 per million |
84 | Durable Objects SQL storage | 5 GB-month | $0.20 per GB-month |
85 | Queues operations | 1M | $0.40 per million |
86 | Containers memory | 25 GiB-hours (90,000 GiB-s) | $0.0000025 per GiB-second |
87 | Containers vCPU | 375 vCPU-minutes (22,500 vCPU-s) | $0.000020 per vCPU-second |
88 | Containers disk | 200 GB-hours (720,000 GB-s) | $0.00000007 per GB-second |
89 | Containers egress, North America and Europe / elsewhere | 1 TB / 500 GB | $0.025 / $0.04 per GB |
90 | Vectorize queried / stored dimensions | 50M / 10M | $0.01 per million / $0.05 per 100 million |
91 | Workers AI neurons | 10,000 a day | $0.011 per 1,000 |
92
93 Not priced yet, so $0 until Cloudflare's lines carry a cost: Artifacts
94 (billed from 2026-10-14), Email Service, Browser Rendering, R2 storage,
95 Cloudflare for SaaS. When Cloudflare changes a price or an included
96 amount, change the table and its test in the same pull request.
97- **Projection**: the cycle's cost so far over the days elapsed, times the
98 cycle's days, as Cloudflare's page projects it ($0.29 over 12 days of a
99 30-day cycle is $0.73).
100- **Subscriptions** (Workers Paid and Workers for Platforms, $30 a month)
101 accrue day by day: each day is its cycle's share of the month's price.
102 The statement's range and g1t's own spend (the calendar month so far) both
103 add up the same days, so they never disagree about a day.
104
105Sudo's Bill & pricing page opens with **This billing cycle**: each meter's
106use, what the cycle includes, what is past it and its cost, the total so
107far, the average day, the projection and the subscriptions. Under it, what
108the last read got back (`cost_reads`): rows, pages, how many rows had a
109consumed quantity and how many only a pricing quantity, and how many carried
110Cloudflare's own cost.
111
112To check the figures against Cloudflare: in the dashboard, Billing →
113Billable usage, for the same cycle. The total so far, the projection and
114each meter's total and billable quantity should agree within a cent. If
115they do not, read the answer itself with a token with Billing Read:
116`GET https://api.cloudflare.com/client/v4/accounts/{account}/billable-usage?from=<cycle start>&to=<today>`,
117and compare, for `Workers CPU ms` and `Container Memory`, the
118`ConsumedQuantity`, `PricingQuantity`, `PricingUnit` and the cost columns,
119and `result_info` for more pages.
120
121## Credentials
122
123| Secret on g1t-billing | Permissions | Used for |
124| --- | --- | --- |
125| `CLOUDFLARE_BILLING_TOKEN` (optional) | Account: **Billing Read**, Account: **Account Analytics Read**, for the g1t account only | Reading the bill, the Artifacts events and the subscriptions |
126| `CLOUDFLARE_USAGE_TOKEN` (exists) | Billing Read, Account Analytics Read, AI Gateway Read | The keeper (settling runs from the gateway's logs); also the bill when `CLOUDFLARE_BILLING_TOKEN` is not set. AI Gateway's analytics are read with this token first and, if that is refused, with the bill's (a token without Account Analytics Read gets an error). When the answer has no rows, billing asks the REST API for the gateway with the same token: 403 means the token lacks AI Gateway Read, 404 that `AI_GATEWAY_ID` names no gateway, 200 that nothing went through it; the `models` drift says which |
127
128With neither, the daily run reconciles only what g1t counted itself, and
129the page says the bill cannot be read. Nothing fails. To set the scoped one:
130
1311. Cloudflare dashboard → My Profile → API Tokens → Create Token → Custom token.
1322. Permissions: Account · Billing · Read; Account · Account Analytics · Read.
1333. Account resources: Include · the g1t account. No zone permissions.
1344. `cd services/billing && npx wrangler secret put CLOUDFLARE_BILLING_TOKEN`.
1355. In sudo, Costs & margin → **Run the analysis now**.
136
137Alerts are emailed through the `EMAIL` binding (Cloudflare Email Sending)
138to `COSTS_ALERT_EMAIL` (`hey@flagon.io`). An empty value sends none.
139
140## Schedule
141
142The daily cron (`17 4 * * *`, `keeper::DAILY`) runs, in order:
143
1441. The keeper's measurements (sandbox seconds, app requests and CPU), each
145 a proposal now, not a direct change.
1462. `costs_daily`:
147 1. Read Cloudflare's subscriptions (and with them when the billing cycle
148 starts), then the bill, the Artifacts events and AI Gateway's
149 analytics. The bill is read over whole billing cycles, every page
150 (see [The billing cycle](#the-billing-cycle)), and priced over each
151 cycle; its days replace what was kept for them. The Artifacts events
152 and the gateway: the first run reads the last 31 days (GraphQL keeps
153 31); later runs the last 4, since Cloudflare restates recent days, or
154 back to the last day read after a gap. Lines are upserted on
155 `(day, source, product, meter)`, so a re-read replaces, never adds.
156 2. g1t's own counts for the same days (replaced per day).
157 3. Snapshot `pending_usage` into `pending_days`.
158 4. Reconcile the last 31 days (further back after a gap, or to the
159 first day of the bill's read) into
160 `margin_days` and `workspace_costs`
161 (replaced per day).
162 5. Drift over the last 7 days into `cost_drift`.
163 6. Unit costs over the last 30 days, proposed to the price book.
164 7. Apply price versions whose date has come.
165 8. Open, update and close margin alerts; email new ones.
166 9. Email owners on the plan about rises to come.
167
168**Run the analysis now** at the top of sudo's Costs & margin and Bill & pricing pages
169(`admin_run_costs`) runs all of step 2 at once, alerts included, with no
170need to wait for 04:17 UTC. Running it twice is safe: every step replaces
171what it wrote.
172
173## Reconciliation math
174
175Every Cloudflare line goes to one of g1t's products ("buckets") by
176`cost_map`: the row for its product with the longest matching meter
177prefix, `*` last. A line no row claims goes to `unmapped`.
178
179| Bucket | Cloudflare | Paid for by (`revenue_map`) |
180| --- | --- | --- |
181| `sandboxes` | Containers, Durable Objects compute duration | `sandbox`, `self_hosted`, `builds` |
182| `deployments` | Workers for Platforms | `deployments` |
183| `git` | Artifacts operations (and its events, as counts) | `git` |
184| `repo_storage` | Artifacts storage | `storage` |
185| `actions_cache` | R2 | `cache` |
186| `embeddings` | Workers AI, Vectorize | `context` |
187| `security` | (Workers CPU, under `platform`) | `security` |
188| `domains` | Cloudflare for SaaS | `domains` |
189| `models` | not Cloudflare: AI Gateway's settled cost on the ledger; AI Gateway's own daily total (`ai_gateway_requests`) beside it, to check it | every other task (agent runs). A planning run's ledger task is `plan`, the same as the plan's payments' key, so it is reconciled as `planning` (`margin::PLANNING_KEY`), which has no `revenue_map` row: models. Before 2026-10-08 its model cost landed in `platform`, where Cloudflare's bill is the cost, and was lost |
190| `platform` | Workers, D1, KV, Queues, Email, Browser Rendering, other Durable Objects | the plan's price |
191
192For each day and bucket:
193
194- **Cloudflare cost** = Σ the bucket's lines' cost, after the included
195 amounts over the billing cycle (see [The billing cycle](#the-billing-cycle)),
196 so a cycle inside them costs $0 here as on Cloudflare's Billable usage
197 page, and the day its total passes one carries the cost. `models` uses the ledger's cost of the
198 tokens instead; that is paid to the model providers and is not on
199 Cloudflare's bill. Its "Cloudflare" column is what AI Gateway priced the
200 same traffic at, which drift compares with the ledger (below); it is
201 never added to the cost.
202- **Own cost** = Σ the ledger's `cost_micros` for the bucket's keys (the
203 price book's cost when charged), plus month-end deltas. A workspace's own
204 model provider is no cost to g1t.
205- **Value** = what customers were charged at price: `-amount_micros` plus
206 what the plan's included usage, a trial, the open-source pool or g1t paid.
207 g1t's own (comped) workspaces are valued at cost plus the margin.
208- **Cash** = what workspaces paid with real money: `-amount_micros`, and
209 the plan's price, from the day payments went live (see "charged without
210 real money" below). Never tax or card fees: a payment credits the
211 balance, and `plan_payments`, without them (see [Tax and the card fee](#tax-and-the-card-fee)).
212- **Given away** = the part of the cost that went on usage g1t paid for
213 itself on purpose, by why:
214 - **comped**: all of a comped workspace's cost, every bucket;
215 - **free use**: a free period's usage, the overruns g1t covered
216 (`ledger.given_micros`), and all of a workspace's cost on a day it had
217 nothing priced (free allowances);
218 - **trial** and **open-source pool**: what `trial_micros` and
219 `oss_micros` paid;
220 - **discount**: what a discount on an account's custom terms took below
221 cost plus the margin (`ledger.discount_micros`, see
222 [Margin floor](#margin-floor)). The usage is valued at its price, so a
223 discounted sale never reads as margin lost;
224 - **promotional credit** and **goodwill credit**: what credit staff gave
225 paid for, when it is spent (`given_credit_promotional_micros`,
226 `given_credit_goodwill_micros`, migration 0038). That usage's charge is
227 taken out of cash, so it is never money in. A refund is not here: see
228 [Credits from g1t](#credits-from-g1t);
229 - **testing resets**: what a workspace's usage cost g1t before staff
230 reset its billing (`reset_costs`, `given_reset_micros`, migration
231 0046). The model calls and Cloudflare usage still happened, so the
232 reconciliation reads the kept rows back as that workspace's usage on
233 their days: valued as before, no cash, all of it given. See
234 [Resetting a test workspace](#resetting-a-test-workspace);
235 - **charged without real money**: what workspaces were charged, and
236 plans paid, while payments were not live (Stripe's test mode), or
237 before the day they went live (`cost_settings.payments_live_since`,
238 kept the first time the run sees live payments). It brought in no
239 money, so it is taken out of cash and given (`given_unpaid_micros`,
240 migration 0052): never money in, never margin, never what a workspace
241 paid. The plan's included usage counts as money in only from that day
242 too.
243
244 Otherwise a workspace's day is split by those shares of its value at
245 price, and the same shares of each of its buckets' cost are given, its
246 part of running g1t included. The Team plan's included usage is sold:
247 the plan's price paid for it. Stored on `margin_days` (`given_micros`
248 and `given_<why>_micros`, `given_discount_micros` from migration 0036)
249 and `workspace_costs` (`given_micros`). Sudo's Costs & margin page lists
250 each why by name, testing resets included (`givenResetMicros`).
251- **Month-end meters**: a day's figure is that day's `pending_days`
252 snapshot less the day before's, within a month. Their month-end ledger
253 entries are left out, so nothing is counted twice. On a 100%-discount
254 workspace the snapshot's charge is valued and given (comped), never cash:
255 the month's close takes all of it off (`margin::comped_meter`).
256- **Product margin** = (value − cost) / value: a share of the price, so
257 cost plus 20% is a 16.7% margin. Sudo labels every margin "of price".
258- **Sudo's statement** keeps apart:
259 - **Usage sold**: cash for usage against the cost of the usage buckets
260 less what was given. Its margin is the headline; at cost plus 20% it
261 sits near 16.7%.
262 - **Running g1t**: the plan's price against `platform` less its given
263 share.
264 - **Cloudflare subscriptions**: what Cloudflare lists, a month
265 (`cf_subscriptions`), accrued over the range day by day as each day's
266 share of its billing cycle (`OverallMargin.subscriptions_micros`);
267 until a read has worked, `CLOUDFLARE_FIXED_MONTHLY_MICROS`, an
268 estimate.
269 - **Not mapped**: billed, charged for by nothing.
270 - **Given away**: by why. A budget, watched under g1t's own spend, never
271 shown as a loss.
272 - **All in**: money in against all of it, with the figure without what
273 was given beside it. **Who g1t paid** is All in's cost, split into
274 Cloudflare's usage, Cloudflare's subscriptions over the range, and the
275 model providers (the ledger's cost); where AI Gateway priced g1t's own
276 provider traffic at more than a cent apart from that
277 (`OverallMargin.gateway_cost_micros`, Cloudflare-billed requests left
278 out), it says so beside it, and the `models` drift says why.
279
280 The overall alert is (Σ cash − (Σ cost − Σ given)) / Σ cash.
281- **Quantities**: where a mapping names an `own_meter`, Cloudflare's
282 billed quantity of those lines (or, without one, Artifacts' operation
283 events) against g1t's own count.
284
285**Shared costs to workspaces.** A bucket's cost is shared in proportion
286to, first available: Cloudflare's own per-workspace count
287(`cloudflare_<bucket>`, today the Artifacts events by repository), g1t's
288own count, what its usage cost (so free use carries its own cost), what
289each was charged for it. `platform`
290and `unmapped` are shared by each workspace's share of all usage that
291day. Shares are whole micros that add up to the bill exactly (largest
292remainder). On a day no workspace used anything, running g1t has no one to
293share it: it stays no one's, and sudo says how much under **Workspaces that
294cost most** (`CostsReport.unattributed_micros`), so the workspaces' costs
295and it add up to the statement's cost.
296
297## Drift (last 7 days)
298
299| Kind | When | What to do |
300| --- | --- | --- |
301| Count | g1t's count and Cloudflare's differ by more than the mapping's `drift_percent` (10%) | Find out what Cloudflare counts: compare its events with `own_counts` `artifacts_*` and `cost_operations`. If it counts more (binding reads, `ls-refs`), either change repos' `operation_mapping` so customers are charged for what Cloudflare counts, or leave it and let the per-unit cost rise (below). |
302| Cost | Cloudflare charged more than `drift_percent` away from the price book's cost of the same usage, with at least `min_daily_cost` | A price is stale: check the proposals. |
303| Cost, on `models` | What AI Gateway priced g1t's own provider traffic at over the 7 days, against the ledger's model cost for the same days (billed to g1t: comped, free and trial use included, a workspace's own provider not) plus the model cost testing resets kept for those days (`reset_costs`), more than the `ai_gateway_requests` mapping's `drift_percent` (10%) apart, with at least `min_daily_cost`. A ledger with none of the gateway's cost is drift too, and so is a gateway that priced nothing against a ledger with at least `min_daily_cost` of model cost (no percentage): that is not agreement. Its detail says why as far as the run could tell: requests logged with no price (add the models' prices), a token Cloudflare refuses for the gateway (give it AI Gateway Read, or fix `AI_GATEWAY_ID`), a gateway the token sees with no requests (calls went around it), or a read that failed | The gateway higher: model calls g1t paid for and charged no one: runs not settled yet (they catch up within the hour), runs with no session, a run started without a billing ticket, or something else on g1t's gateway. The ledger higher: runs that reached a provider without the gateway. The detail adds why the gateway's own figure may be off: prompt-cache read and write tokens (the gateway prices them at its rates for cache tokens, which can lag the provider's; check against the provider's invoice), requests Cloudflare billed itself (unified billing: on Cloudflare's bill, not a provider's), and models with no price. A testing reset in the window is named in the detail: one that kept its cost says how much of the ledger's side it is; one from before resets kept their cost (the audit log has it, `reset_costs` does not) says the gateway's figure includes usage the ledger no longer has, so that part is not a leak, and the day it leaves the 7 days; while such a reset is in the window the `models` leak is not raised. Days are UTC by when a request ran (gateway) and when a charge was entered (ledger), so a run across midnight shifts a little between days; the 7-day sum absorbs it. |
304| Unpriced | Over the 7 days, a model in AI Gateway's analytics with tokens and $0 cost, or runs settled with `runs.gateway_note` (the gateway could not price all of a run) | The gateway has no price for a model g1t runs: add it in the gateway (custom cost) or route away from it. Until then those runs are charged no less than the sandbox reported (Claude Code's own price table), never $0 silently. |
305| Leak | Cost of at least `min_daily_cost` and nothing charged for it (never for `platform`), or a meter in `unmapped` | Map the meter (below), or decide it is overhead (`platform`). |
306
307## Prices: versions, proposals, notice
308
309- `price_versions` holds every price ever, never edited. `prices` is the
310 version in force. The daily run applies a version once its
311 `effective_at` has come, and adds the public `price_changes` record.
312 Ledger entries made from the price book carry `price_version` (the
313 version ids, comma-separated), so a past statement is always explained
314 by the prices of its day.
315- Proposals come from the keeper (sandbox seconds, app requests and CPU)
316 and the reconciler (mappings with `scale_to_own`: today git operations).
317 For git operations: Cloudflare's rate per its own operation (the median
318 over charged days of cost ÷ quantity) × (Cloudflare's operations ÷ g1t's)
319 × 1,000. If Cloudflare counts three for each one g1t counts, the per-1,000
320 price triples. At least 1,000 of g1t's operations are needed.
321- Decision (`pricing::decide`): under 2% is noise; more than 4× either way
322 is suspect and waits for staff; within `auto_apply_percent` (25%) it is
323 applied on its own when `auto_apply` is on; anything else waits.
324- Notice: a fall applies at once. A rise applies `notice_days` (14) after
325 the decision, and for a monthly meter (git, storage, cache, domains,
326 embeddings, scans) at the start of the month after that, so no month
327 is charged at two prices. Owners of workspaces on the plan are emailed
328 once per rise (`price_notices`), and the pricing page lists it with
329 "takes effect". Rises are never retroactive; margin protection is for
330 new usage once notice has run.
331- A newer measurement before a rise's date replaces its version, with
332 the new rise's own full notice; the proposal behind the replaced version
333 is marked `superseded` (it never took effect, and nothing was charged at
334 it). Sudo says "applied by guardrail, then replaced by a later
335 measurement". Migration 0049 marks the ones from before: sandbox and
336 build seconds' rises of 2026-10-07, replaced on 10-08.
337- Staff approve or reject in sudo. A rejection needs a note.
338- **Price versions** in sudo show each version's cost and price, except
339 where the cost column is not a cost (`PriceVersion.basis`,
340 `pricing::basis_of`): the agent rate and security activation are rates
341 g1t sets (`rate`, no cost shown), and the agent rate's token weights are
342 multipliers (`weight`, shown as ×0.1). Dates show with their time: a
343 version from 00:00 UTC is the evening before in the Americas.
344
345## Changing a mapping
346
347In sudo, Costs & margin → Bill & pricing → **Mappings**: Cloudflare's product and meter
348prefix (as **Cloudflare's lines** lists them; `*` for the rest of the
349product), g1t's product, and optionally:
350
351- **Price meter**: the price book meter the line measures.
352- **Own meter**: g1t's count of the same units (`own_counts.meter`).
353- **Scale to g1t's count**: price one of g1t's units at as many of
354 Cloudflare's as it took (proposals as above).
355- **Drift threshold**.
356
357It applies from the next run; **Run the analysis now** applies it at once.
358Every change is in the audit log (`cost_mapping`).
359
360## Which raw meters are operations
361
362There is one mapping, and the repos service owns it: `operation_mapping`
363in g1t-repos' database, one row per raw meter with `cost_operations` (how
364many operations Cloudflare bills for it) and `billable_operations` (how
365many the customer is charged for). Change it with repos'
366`set_operation_mapping` RPC (services only), or
367`npx wrangler d1 execute g1t-repos --remote` until sudo has a form. A
368change applies to counts from then on, never to what was counted.
369Billing keeps no mapping of its own: it reads repos' `git_operations`
370(already mapped) for what customers are charged, and `artifacts_usage`
371(raw counts with the mapping) for `cost_operations`. Migration 0023 drops
372the `billable_units` table 0022 made for this, which was never written.
373
374**Charged at price** (a product's value) is what each day's usage was paid:
375charged to a card or credit, or drawn from the plan's included usage, a
376trial, a pool or a gift. Usage nothing paid for, as in a free period, is
377valued at price (cost plus the margin), since it was given away at its price
378rather than sold for nothing; so are g1t's own workspaces. Runs on a
379workspace's own model provider have no cost to g1t. Every daily run
380reconciles the whole 31-day window from what is already kept, so a change in
381how a day is valued reaches every day sudo shows.
382
383## Alerts runbook
384
385| Alert | Raised when | First steps |
386| --- | --- | --- |
387| Margin under the floor | A product's value against cost under `margin_floor_percent` (10%) for `alert_days` (3) days running, each with at least `min_daily_cost` | Open the product on Costs & margin. Cost up? Check proposals (approve a rise; it waits out the notice). Value down? A mapping or `revenue_map` may have moved. |
388| All of g1t under the floor | The same for money in against the cost of what was sold: every cost less what was given away (comped workspaces, free periods, the trial, the pools), which is a budget watched in budget.rs. While less than $1 a day comes in, it says the dollars, not a percentage | Look at which products moved; check `platform` (it has no revenue of its own and grows with traffic). Before launch, with little paid usage, expect it. |
389| Leak | Drift of kind leak | Map the meter, or decide it is overhead. |
390| Drift | Count drift | See Drift above. Cloudflare's definitions change in beta: ask them in writing ([ARTIFACTS.md](ARTIFACTS.md), §7). |
391| Costs more than it pays | A workspace's shared cost over 30 days above what its usage was priced at (`value_micros`, whoever paid: card, trial, gift or included usage) × `anomaly_factor`, at least `anomaly_floor`; not comped workspaces | Shown on Reach out as "Costs more than it pays": its usage is priced below what it costs. Abuse (Abuse & fraud page) or a gap in pricing. Not emailed. A trial or gift paying for usage does not raise it. |
392
393Alerts close on their own when the condition clears. Open ones are
394emailed again weekly. The red bar on every sudo page shows margin,
395overall and leak alerts.
396
397## Model costs
398
399Every model call g1t pays for is an agent run's (the `claude` CLI in the
400sandbox, `crates/runner`) or a customer's AI Gateway request (a workspace
401token with `models:write` at `models.g1t.sh/anthropic` or
402`models.g1t.sh/openai/v1`, `gateway.rs`, to Claude on Anthropic or to open
403models on Workers AI through the same AI Gateway); the only other model is
404Workers AI's embeddings for g1t's own search, which are on Cloudflare's bill
405(`embeddings`). How each reaches the ledger:
406
407| Call | Who pays | Run and session | Ledger cost | Settled to the gateway |
408| --- | --- | --- | --- | --- |
409| Agent run through the model proxy (`services/models`) on g1t's hosted models | g1t | `runs` row; session `ms_…` in `cf-aig-metadata` | On finish, the sandbox's figure (Claude Code's `total_cost_usd`, at its own price table, cache tokens included) | Yes, every 15 minutes |
410| Agent run straight to the gateway (no `MODELS_URL`) | g1t | `runs` row; session `rs_…` in `cf-aig-metadata` (`services/runner` `gatewaySession`) | As above | Yes |
411| Agent run with no gateway (`AI_GATEWAY_ID` empty, self-hosting) | g1t's key | `runs` row, no session | The sandbox's figure | No: nothing to settle against |
412| Agent run on a workspace's own provider | The workspace | `runs` row, `billed_to = 'workspace'`, session `ms_…` (the proxy counts its tokens by it) | No model cost (none to g1t); the agent rate on `agent_tokens_own`, line `<run>/agent-own` | No; never on g1t's gateway. Closed by the cron's `settle_own_runs`, which charges tokens counted late |
413| AI Gateway request on g1t's key | The workspace, from included usage and AI credit (`gateway_admit` refuses at $0, over the limit, or with no plan) | No run; `gateway_requests` row; session `gw_<token>_<YYYYMMDDHH>` in `cf-aig-metadata` (`task: gateway`) | Per request: its tokens at `gateway_models` (the table, migrations 0045 and 0047: list price per million by kind, five-minute and one-hour cache writes apart, and for a model priced by prompt length such as Claude Haiku 5.5 a `threshold` above which the whole request is at the `over_` prices) plus the `gateway_models` meter's markup (0 in beta); a `usage` line with task `gateway`, reference the request id, quantity 1 | No, not yet: the session tag is there for it. **Cost** drift on `models` compares the gateway's total with these lines too. Requests billed other than by tokens (fast mode, `inference_geo`, fallbacks, server tools, containers) are refused by the proxy |
414| AI Gateway request on a workspace's own provider (any model connection whose `gateway_models` takes the model) | The workspace's provider | `gateway_requests` row, `own_key = 1`, `provider` and `connection` | None | No; never on g1t's gateway |
415| A sandbox that died before reporting | g1t | as its route | Charged from the gateway when settled | Yes |
416| Embeddings (indexing) | g1t | none (Workers AI) | Month-end `context` meter | No: Cloudflare's bill, `embeddings` bucket |
417| Embeddings (queries, search and agent context) | g1t | none | None: not charged, by design | No: in Cloudflare's `embeddings` line, shared out |
418
419**Settling.** A run's charge is corrected to what AI Gateway priced its
420session's requests at (`settled_cost` in `keeper.rs`). The gateway's
421figure is trusted in full: it is not held to the $100 cap on a sandbox's
422own report. It is never taken below what the sandbox reported when it
423cannot be the whole cost: a request with tokens and no cost (a model the
424gateway has no price for) or more logs than are read (2,000). Such a run
425keeps `runs.gateway_note`, its correction says why, and it raises the
426**Unpriced** drift. For agent runs g1t keeps no token rates of its own:
427the first figure is Claude Code's, the final one the gateway's. AI Gateway
428requests are the exception: they are charged from `gateway_models` (the
429model catalogue, below), which has to follow the provider's price list by
430hand until they are settled like runs. It is not part of the price book's
431`price_versions`: a new model's prices are confirmed when staff approve it
432in sudo, and a changed price on a model already offered is a migration that
433updates the row and its `updated_at` (as 0047 did for Sonnet 5.5's cache
434reads). The `gateway_models` meter's markup is the only price-book number
435on it. Open
436models need `WORKERS_AI_TOKEN` (a Cloudflare API token with Workers AI on
437g1t's account) on the model proxy; without it, and without
438`AI_GATEWAY_TOKEN` holding that permission, they are refused with `503`.
439
440**The daily total.** AI Gateway's analytics for the day (above) against
441the ledger's model cost is the check that nothing slips past: a model call
442with no run, or a run never settled, shows as **Cost** drift on `models`.
443The gateway's per-request `cost` is its estimate from its own price list:
444it can be off for prompt-cache tokens, for requests Cloudflare bills
445itself, and for models it has no price for. The drift's detail says when
446any of those were in the window; the provider's invoice is the last word.
447
448### Margin floor
449
450A sold charge is cost × (1 + `MARGIN_PERCENT`), rounded up (`margin_on`;
451`charge_micros` for a sandbox's own report). Terms change it only as
452follows (`Terms::discounted`, `Billing::charged`):
453
454- **Standard**: charged in full.
455- **A 100% discount** (what was "comped"; see [Discounts](#discounts)),
456 `FREE_WHILE_BUILDING`, the plan's included usage, the trial,
457 the open-source pool, and overruns g1t covers: given, and counted by why
458 (above).
459- **Custom, with a discount**: the discount comes off, and what it took
460 below cost plus the margin is written on the entry as
461 `ledger.discount_micros` and counted as given (**discount**), so the sale
462 is valued at its price and charged plus given is never under cost plus the
463 margin. On a settlement correction it moves with the charge (less than
464 nothing when the charge comes down).
465- **Goodwill credits** (overages) are separate, given by staff on purpose:
466 their margin part first, the cost only up to the cap, each audited.
467
468Every usage path goes through this: `finish_run`, settling, sandbox time,
469features and builds (`charge_feature`), and the month-end meters.
470
471## The model catalogue
472
473Every model g1t can use is one row of `gateway_models` (migrations 0045,
4740047 and `0048_model_catalogue.sql`; code in `catalogue.rs`): the agents'
475tiers, the AI Gateway's Claude and open models, and the embeddings model.
476Billing keeps it because billing owns prices: the gateway charges from the
477same row, so there is one price per model, not two that drift. Page: sudo
478**Agents & models** (`/agents`).
479
480| Column | What |
481| --- | --- |
482| `model`, `name`, `provider`, `kind` | The provider's id, the name people see, `anthropic` or `workers-ai`, `chat` or `embeddings` |
483| `aliases` | Other ids the provider lists it by, comma separated (a dated id such as `claude-haiku-4-5-20251001`) |
484| `family`, `tier_hint` | `haiku`, `sonnet`, `opus`, `fable` (or a Workers AI author); the agent tier it suits: `small`, `large`, `frontier` |
485| `context_window`, `max_output`, `capabilities`, `dimensions` | From the provider's list where it gives them: `effort`, `thinking`, `tools`, `vision`, `embeddings`; an embeddings model's vector length |
486| Prices | Per million tokens in millionths: input, output, cache read, five-minute and hour-long cache writes, and for a model priced by prompt length the `threshold` and `over_` prices |
487| `status` | `available` (routed to and offered), `new` (found, not approved), `deprecated` (the provider stopped listing it), `retired` (staff took it out) |
488| `priced` | 1 when its prices are known |
489| `source`, `first_seen_at`, `last_seen_at`, `missing_since`, `approved_by`, `approved_at`, `note` | Where it came from (`discovered` or `staff`) and its history |
490
491What each status allows:
492
493| Status | Default for a purpose | Offered on the AI Gateway | Charged |
494| --- | --- | --- | --- |
495| `available`, priced | Yes | Yes | Yes |
496| `new`, or unpriced | No | No: refused before it reaches a provider | No |
497| `deprecated` | No: a default that chose it falls back | Yes, to whoever names it | Yes |
498| `retired` | No: a default that chose it falls back | No | No |
499
500### Discovery
501
502The models service lists each provider once a day (`29 5 * * *`, after
503billing's daily run) and whenever staff press **Check for new models**
504(`services/models/src/discover.ts`, through its `Discovery` entrypoint,
505which only sudo binds). Listing models is free; nothing calls a model.
506
507| Provider | How it is listed | Credentials (on g1t-models) |
508| --- | --- | --- |
509| Anthropic | `GET /v1/models` through g1t's AI Gateway (`…/anthropic/v1/models`, tagged `task: discovery`), or straight to Anthropic with g1t's key when there is no gateway | `AI_GATEWAY_TOKEN` (the gateway holds Anthropic's key), or `ANTHROPIC_API_KEY` |
510| Workers AI | `GET /accounts/{account}/ai/models/search` | `WORKERS_AI_TOKEN` (Workers AI Read), else `AI_GATEWAY_TOKEN` |
511
512Each provider's list goes to billing's `record_discovery`, which compares
513it with the catalogue:
514
515- **An id it has never seen** is added as `new`. Chat and embeddings
516 models only. Anthropic models are priced from the price table in
517 `catalogue.rs` (`ANTHROPIC_PRICES`: Anthropic's list prices by model, a
518 dated id priced as its model) when it has them; Workers AI models from
519 the price their listing gives, with cached tokens at the input price.
520 Anything else is added unpriced. Its family and tier hint come from its
521 id (`claude-haiku-*` is fast, `claude-sonnet-*` standard,
522 `claude-opus-*` and `claude-fable-*` most capable).
523- **A dated id of a model it has** (`claude-sonnet-5-5-20261001`) is that
524 model: the id is added to its aliases.
525- **A model it has that is listed** gets `last_seen_at`, and its context
526 window, output limit and capabilities from the list.
527- **A model it has that is not listed** (available or new) becomes
528 `deprecated`, with `missing_since`. Listed again, it goes back to
529 `available` if it was ever approved, else to `new`.
530- **An empty list or a failed one** changes nothing: it is recorded as a
531 failed check with the provider's answer (never a key).
532
533Every check is kept 90 days in `model_checks` and shown on the page. When a
534check adds, deprecates or restores anything, it is in the audit log
535(`models_discovered`, as `schedule` or the staff member) and staff are
536emailed at `COSTS_ALERT_EMAIL` with a link to Agents & models.
537
538When Anthropic publishes a new model's price, add a row to
539`ANTHROPIC_PRICES`, so the next one of its kind arrives priced. Until then
540staff enter the prices when they approve it.
541
542### Approving, retiring and restoring
543
544On Agents & models, **New models** lists every `new` model with its prices
545filled in where they are known. To approve one:
546
5471. Check the name people see and the tier it suits.
5482. Check or enter its prices per million tokens against the provider's
549 price page: input, output, cache read, cache writes (five-minute and
550 hour-long; an hour-long price left empty is the five-minute one), and
551 under **Priced by prompt length** the threshold and the prices above it.
5523. Say why (for example where the prices came from), and **Approve**
553 (`admin_decide_model`, `approve`).
554
555It is `available` at once: the AI Gateway offers it within five minutes
556(the proxy keeps the catalogue that long) and it can be chosen as a
557default. **Retire** takes a model out of routing and the gateway; any
558default that chose it falls back to the next suitable model until staff
559choose another, and the audit line names those defaults. **Restore** puts
560a retired or deprecated model back: `available` if it was ever approved,
561else `new`. Each needs a reason and is in the audit log (`model_approved`,
562`model_retired`, `model_restored`).
563
564### Defaults
565
566`model_defaults` holds staff's choice per purpose, each with when, who and
567why (`admin_set_model_default`; the audit log, `model_default`, has the old
568value, the new one and why):
569
570| Purpose | What it chooses | Read by |
571| --- | --- | --- |
572| `tier_small`, `tier_large`, `tier_frontier` | The model behind Auto's fast, standard and most capable tiers | The runner |
573| `background` | The harness's own small tasks in every run on g1t's tiers (`ANTHROPIC_SMALL_FAST_MODEL`, `ANTHROPIC_DEFAULT_HAIKU_MODEL`) | The runner |
574| `gateway_first` | The Claude listed first by `GET /openai/v1/models` | Billing's `gateway_models` |
575| `job_implement`, `job_revise`, `job_answer`, `job_review`, `job_update`, `job_plan` | Each kind of job's starting tier (`small`, `large`, `frontier`; a review also `change`, sized by its change) and effort (`low` to `max`, or none for the harness's own) | The runner |
576
577A model purpose takes only an available, priced Claude chat model (the
578harness speaks Anthropic's API). The migration seeded each with what
579`AGENT_ROUTING` had.
580
581Before a default is saved, sudo shows it beside the current one with what
582a **typical run** would cost on each: 40 requests of 2,000 input, 1,500
583output, 45,000 cache-read and 4,000 cache-write tokens, each request priced
584on its own at the catalogue's prices (`catalogue::TYPICAL`; on 2026-10-08,
585$0.076 on Claude Haiku 5.5, $1.34 on Sonnet 5.5, $2.68 on Opus 5.5). It is
586an estimate for comparing models, never a charge.
587
588**How the runner reads them.** `model_defaults` (the RPC) returns each
589purpose's model as it applies now, with its prices and capabilities, and
590each job's tier and effort. The runner reads it at most once a minute per
591isolate and puts it over `AGENT_ROUTING` (`withDefaults` in
592`services/runner/src/model-env.ts`), so a change reaches runs within a
593minute. When billing cannot be read, the runner uses `AGENT_ROUTING` (and
594`DEFAULT_ROUTING` under it) alone and asks again ten seconds later. The
595labels, change sizes, `frontierAfter` and learning always come from
596`AGENT_ROUTING`. Effort is not sent on a model whose catalogue entry lacks
597`effort` (Claude Haiku 4.5).
598
599**Never a retired model.** A chosen model that is deprecated, retired or
600unpriced is not handed out: the purpose falls back to the first available,
601priced Claude with the same tier hint (any Claude for `gateway_first`), in
602the catalogue's order, with a sentence such as *Claude Haiku 5.5 is
603retired; using Claude Haiku 4.5 instead.* The runner adds that sentence to
604the run's reason line, and sudo shows it beside the default. With no model
605left for a purpose, the runner keeps `AGENT_ROUTING`'s.
606
607**Not a default:** the context hub's embeddings model
608(`@cf/baai/bge-base-en-v1.5`, in `services/context`). Its vectors are
609only comparable with others from the same model, so changing it means a
610new index, rebuilt; it is pinned in code, and listed in the catalogue with
611its price. No other g1t service calls a model.
612
613Customers never choose among these: they keep **Auto**, or pin a tier per
614kind of work, and nothing customer-facing names the catalogue.
615
616## Discounts
617
618An account's terms are standard, or custom: a **discount** from 1 to 100%,
619a limit of its own, or both, with a reason (the terms' note) and an
620optional end date. What used to be "comped" is a **100% discount**
621(`Terms::full_discount`; migration `0039_discounts_not_comped.sql` moved
622every `comped` row to `custom` at 100%, and code reads a leftover `comped`
623row as 100%). In SQL, `sales::FULL_DISCOUNT_SQL`.
624
625- **Charging.** Every charge records what the discount took off it
626 (`ledger.discount_micros`), 100% included: the entry is charged nothing
627 and the discount is its whole price. Migration 0039 backfilled the
628 discount on a 100%-discounted workspace's earlier entries that were
629 charged nothing and paid by nothing, at cost plus 20%.
630- **What a 100% discount still does as "comped" did.** The plan is on
631 without its price (`PlanKind::Internal`), trust is `internal` (no limit
632 on unpaid usage), nothing is invoiced or closed, and g1t's own spend on
633 it is held to the monthly budget (the terms' limit, at cost; see
634 [Spend caps](#spend-caps)).
635- **The statement and Usage.** The customer sees every usage line at its
636 price (`StatementLine.price_micros`: charged, plus what paid for it, plus
637 the discount), the discount per day or project and in the totals
638 (`StatementTotals.price_micros`, `discount_micros`, `discount_percent`),
639 and the CSV has price and discount columns. The Usage page measures at
640 price for a discounted account (`Usage.discount_micros`,
641 `discount_percent`).
642- **Margin.** A 100% discount's usage is given away as before, in the
643 bucket still named `comped` (`given_comped_micros`); sudo calls it
644 **100% discounts**. A partial discount's part below cost plus the margin
645 is `given_discount_micros` (**partial discounts**). Both are kept apart
646 from margin on what was sold.
647- **sudo.** The workspace's **Terms** form takes a discount (None, 25%,
648 50%, 100%, or Custom, a whole percent; the custom field shows by CSS
649 alone), a limit, an end date and the reason. Badges and filters say
650 *100% discount* or *N% off*. Each change is audited (`terms`), such as
651 `standard → 100% discount, monthly budget $150.00: g1t's own`.
652
653## Credits from g1t
654
655Staff give a workspace credit from sudo; the code is
656`services/billing/src/grants.rs`, the tables `credit_grants` and
657`ledger.credit_kind` (migration `0038_staff_credits.sql`).
658
659### Giving credit
660
661sudo → the workspace (or an enterprise, choosing one of its workspaces) →
662**Give credit**:
663
6641. **Amount**: $10, $20, $25, $50, $100, or **Custom** (up to $10,000).
665 Up to $100 it is one step; over $100, type the workspace's slug as well.
6662. **Kind**: promotional (a welcome, a referral, an event), goodwill (an
667 apology), or refund (money back for something that went wrong: say what
668 it refunds and, optionally, the day).
6693. **Expires**: never, 30, 90 or 365 days, or the end of a chosen day
670 (UTC). A refund never expires.
6714. **Note**: required. It is on the statement and in the owners' email.
672
673The form needs no JavaScript: the fields for one choice (the custom amount,
674a refund's details, the expiry date) show by CSS alone, and all show where
675`:has()` is not supported. `admin_credit` checks everything again.
676
677A grant is a `crd_…` ledger line (kind `top_up`, so never a payment) with
678`credit_kind`, and a `credit_grants` row. The balance rises at once. The
679owners are emailed through identity's `notify_owners` (the same path as
680limit notices). It is audited as `credit`. The Overages queue's one-click
681goodwill credit is a grant too, of kind goodwill.
682
683The inbox is not told: its items are threads on a repository, built from
684events, and a credit is a workspace's. That needs a workspace-level inbox
685thread first.
686
687### How it is spent
688
689Credit is spent before anything prepaid, the soonest-expiring grant first
690(never-expiring last, then the oldest). Given while the workspace owes, it
691pays what is owed first, the most recent usage first. What each grant paid
692for is never stored: `grants::replay` works it out from the ledger in order,
693so the charge paths do not know about credit and the answer is always what
694the ledger says. A charge that comes down (a settled run) gives back to
695the grant that paid last, while it can still be spent.
696
697### Expiry and revoking
698
699- **Expiry.** The daily run (`expire_credits`, before the reconciliation)
700 closes grants past `expires_at` and enters what was left as a negative
701 `crd…_expired` line; audited as `credit_expired`. A grant past its expiry
702 pays for nothing even before the run.
703- **Revoke.** sudo → the workspace's **Credits** (or **Credits & refunds**)
704 → **Revoke unused**, with why (`admin_revoke_credit`): what is left, as a
705 `crd…_revoked` line, audited as `credit_revoked`. What was spent stays
706 spent.
707
708Neither takes the balance below zero: at most the balance, if a refunded
709payment left less there than the credit.
710
711### How margin treats them
712
713| Kind | When spent | On the day it was given |
714| --- | --- | --- |
715| Promotional | The usage is valued at its price, its charge comes out of cash and is given (`given_credit_promotional_micros`) | Nothing |
716| Goodwill | The same, as `given_credit_goodwill_micros` | Nothing |
717| Refund | Paid for: cash, as any usage | Its amount (less what was revoked) comes off cash on the day it refunds, shared over that day's paid usage |
718
719A refund gives back money already collected, so counting it as given would
720make it look like a budget g1t chose to spend. Taking it off cash for the
721day it refunds says that day's sale was worth less, and counting what it
722later pays for as cash keeps money in equal to what was collected. The
723refund's day is clamped to the last 30 days, the days the reconciliation
724recomputes; an older one lands on the oldest. Refunds never expire, so
725cash taken back is never stranded.
726
727What credit paid of a month-end meter (storage, git, scans) is its own
728row on the day it was charged, since those meters are reconciled from
729snapshots. Sudo's Costs & margin lists promotional and goodwill credit
730under **Given away**, and below the statement the range's credits given,
731spent, and refunded. **Credits & refunds** (`/credits`, `admin_credits`)
732lists every grant (by kind, month, staff and workspace) and the last 12
733months by kind: given, spent, expired, revoked.
734
735### Purchased and scoped credit (prepaid AI)
736
737`credit_grants` also has `scope` (`all`, or `models`: model usage only,
738`grants::is_model_usage`, which includes the agent rate) and `source`
739(`staff`, `purchase`, `promo_code`, `upgrade`), and `CreditKind::Purchased`.
740Spending takes credit scoped to models first, then the soonest-expiring. A
741grant scoped to models given while the workspace owes pays only what models
742owed, never other usage (`replay`). Purchased credit is money paid in: its
743ledger line is a payment (Stripe's id, never `crd…`, `credit_kind`
744`purchased`, statement kind *AI credit*), and the usage it pays for stays
745money in, never given. Staff cannot give it (`admin_credit` refuses the
746kind). Code: `services/billing/src/ai.rs`; migration `0040_ai_credit.sql`.
747
748- **Buying.** `buy_ai_credit` opens Stripe Checkout (payment mode, $10 to
749 $1,000, a second line *Card processing fee* when the `card_fee` cost
750 setting is on, `setup_future_usage=off_session`), recorded in `checkouts`
751 with `feature = 'ai_credit'`, `amount_cents` the credit and `fee_cents`
752 the fee. The credit is entered by whichever comes first, the person coming
753 back (`confirm_ai_credit`, `?ai_credit=cs_…`) or
754 `checkout.session.completed`: both claim the row `open → paid`, the
755 grant's id is the session's id (`INSERT OR IGNORE`) and the ledger's
756 reference is unique, so a payment is credited exactly once. Expires 365
757 days after purchase (the daily `expire_credits`).
758- **Owed.** AI credit props up the balance but is money only for models, so
759 what is owed is `max(0, AI credit left − balance)` (`owed_with`; at a
760 month's close, `models_left_before` the month's start).
761- **Auto-reload.** `ai_reload` (settings; off by default) and `ai_reloads`
762 (one row per attempt). Each cron run (and a run that would be refused)
763 calls `reload_now`: below the threshold, it charges the customer's default
764 payment method off-session for the target less the balance (whole
765 dollars, at least $10, within the month's maximum), with the idempotency
766 key `reload/<workspace>/<YYYY-MM>/<n>` (a retry after a crash is the same
767 PaymentIntent), and grants purchased credit with the PaymentIntent's id. A
768 decline or a payment needing the person turns auto-reload off
769 (`failed_at`, `error`), emails the owners and audits `ai_reload_failed`.
770- **At $0.** `start_run` on g1t's models refuses with `payment_required`
771 when the workspace is on the paid plan (not a 100% discount, not an
772 enterprise), its included usage is used, and AI credit is $0 or less.
773- **Upgrade credit.** The first time a plan subscription is recorded active
774 (`features::record`), $5 of promotional credit scoped to models, id
775 `crd_upgrade_<workspace>`, expiring in a year: given, never revenue. Never
776 for a workspace with a 100% discount.
777
778### The agent rate and models' markup
779
780Price-book meters (migration 0040, each with versions and a public change):
781`agent_models` (per provider dollar; markup 20% until 2026-10-08, then 0,
782a fall applied at once), `agent_tokens` ($0 until 2026-10-22, then $0.25 a
783million tokens: a rise, after the 14 days' notice, emailed to owners on the
784plan by `tell_owners_of_rises`), `gateway_models` (markup 0 during beta),
785`card_fee_percent` (29,000 micros per dollar) and `card_fee_fixed`
786(300,000). Changing any is a price-book change, never a deploy. `finish_run`
787and `settle` charge models at `agent_models`' markup; `charge_agent_rate`
788charges the weighted tokens of the run's session since it was last charged
789(`runs.agent_tokens`, the weighted tokens charged so far, claimed with a
790compare-and-set), on a line `<run>/agent` (later `<run>/agent/<tokens>`),
791with `quantity` the weighted tokens. What it counts is the more of what
792`token_usage` holds for the session and what the sandbox reported with its
793cost (`finish_run`'s `tokens`, from Claude Code's closing `usage`), each
794weighted by kind. **Card fee switch:** sudo → Costs → Guardrails → *Card fee
795on card payments* (`cost_settings.card_fee`, `on`/`off`, on by default). It
796covers every card payment now, not only AI credit: see
797[Tax and the card fee](#tax-and-the-card-fee).
798
799**On a workspace's own model key** (migration `0041_agent_rate_own_key.sql`):
800the run keeps its model session (`runs.session_id`, `ms_…`) so the proxy's
801counts reach it, and the agent rate is charged at `agent_tokens_own` ($0 until
8022026-10-22, then $0.25 a million, a rise from nothing with its notice), on
803`<run>/agent-own` (later `<run>/agent-own/<tokens>`), `billed_to = 'g1t'`
804(g1t's own charge: it counts toward limits and spend), named *Agent rate,
805your own model key* on Usage and the statement. The model is never charged.
806`settle_runs` skips these runs (nothing on g1t's gateway); the cron's
807`settle_own_runs` closes them 5 minutes after they finish (3 hours after
808they start, for a sandbox that never reported) and charges tokens counted
809late. Runs from before have no session and are never charged the rate.
810
811### The agent rate's token weights
812
813How much each kind of token counts toward the agent rate, on g1t's models
814and own keys alike, is four price-book meters (migration
815`0042_agent_rate_weights.sql`): `agent_token_weight_input`, `_output`,
816`_cache_read` and `_cache_write`, each a weight in millionths in
817`cost_micros` (1,000,000 counts a token once). They started at 1, which is
818what the rate always counted; since 2026-10-08 cache reads count a tenth
819(100,000; migration `0044_cache_reads_count_a_tenth.sql`), as model providers
820price them. Input, output and cache writes count once. A cached agent run reads most of its context from
821cache (about 90% of its tokens on a typical Sonnet implement run), so the
822cache-read weight is the lever: at 1 the rate adds about 44% to such a run's
823model cost; at 0.1, far less.
824
825To change a weight (cache reads went to a tenth this way):
826
8271. Add the version, effective at once (a lower weight is a fall):
828
829 ```sql
830 INSERT INTO price_versions (id, meter, version, cost_micros, markup_percent, effective_at, reason, created_by, created_at)
831 VALUES ('pv_agent_token_weight_cache_read_2', 'agent_token_weight_cache_read', 2, 100000, 0,
832 '2026-10-08T00:00:00Z', 'Cache reads count a tenth toward the agent rate', 'staff', '2026-10-08T00:00:00Z');
833 ```
834
835 in a migration, or with `npx wrangler d1 execute g1t-billing --remote`
836 until sudo has a form.
8372. The daily run applies it once `effective_at` has come and writes the
838 public `price_changes` record (**Run the analysis now** applies it at
839 once). Raising a weight later is a rise: give it an `effective_at` 14
840 days out, and owners on the plan are emailed.
8413. Check `/pricing`: the agent rate's row lists the weights, and Usage's
842 agent-rate lines name them.
843
844`weighted` (`ai.rs`) rounds down to a whole token; a weight is never below 0.
845
846### Budgets
847
848The owners' spend limit is the budget. `limits.alert_levels` (comma
849separated, default every level), `limits.pause_at_limit` (default 1; off,
850100% is a warning, never a stop; the trust ceiling still stops work) and
851`limits.budget_webhook` (an https address, not g1t's; posted once per alert
852level a month by `warn_limits`). `set_budget` sets them, with `keepLimit`
853to leave the limit itself alone. A free workspace (trust `new`) has no
854spend limit to set: `set_spend_limit` and `set_budget` say so.
855
856### Earlier credits
857
858Migration 0038 makes every earlier `Credit from g1t:` line a goodwill
859grant with no expiry: the old form asked for "a refund or goodwill" with
860no way to tell them apart, and goodwill never reads as money in.
861
862## Token usage
863
864The model proxy (`services/models`) reads Anthropic's `usage` from every
865`/v1/messages` answer, streamed or whole, on g1t's models and on a
866workspace's own provider alike (OpenAI-shaped providers are translated
867first). Count-tokens requests are not answers and are skipped. After the
868answer, it calls `record_tokens`, which adds input, output, cache reads and
869cache writes to one row per day, workspace, person, session and model in
870`token_usage` (migration `0030_token_usage.sql`). The person is who the run
871was for, from the model session's `requested_by`; never g1t's agent. A
872report that fails is dropped and never affects the answer.
873
874`token_usage` reads a window (42 days by default, 366 at most) for the
875workspace or one person: totals, every day's tokens and the active days,
876with `costMicros` the window's run charges from the ledger, measured as
877`usage` measures them. Usage's report also lists tokens by model
878(`UsageReport.models`). The agent rate is charged on these counts (above);
879a run's model is still priced from AI Gateway's logs, never from them.
880
881## Tables (migration `0022_costs_and_margin.sql`)
882
883`cost_lines`, `cost_map`, `revenue_map`, `own_counts`,
884`pending_days`, `margin_days`, `workspace_costs`, `cost_drift`,
885`margin_alerts`, `price_versions` (seeded with every current price as
886version 1), `price_proposals`, `price_notices`, `cost_settings` (the
887guardrails, seeded), the `actions_cache` price, and `ledger.price_version`.
888Every create is `IF NOT EXISTS` and every seed `INSERT OR IGNORE`; the one
889`ALTER` is applied once by D1's migration tracking. Migration
890`0023_one_operation_mapping.sql` drops `billable_units` (see above).
891Migration `0036_model_costs_in_full.sql` adds `ledger.discount_micros`,
892`margin_days.given_discount_micros`, `runs.gateway_note` and the
893`ai_gateway_requests` → `models` mapping. Migration
894`0038_staff_credits.sql` adds `credit_grants`, `ledger.credit_kind` and
895`margin_days.given_credit_{promotional,goodwill}_micros`, and backfills
896earlier credits (see [Credits from g1t](#credits-from-g1t)). Migration
897`0046_reset_costs.sql` adds `reset_costs` and `margin_days.given_reset_micros`
898(see [Resetting a test workspace](#resetting-a-test-workspace)). Migration
899`0052_cloudflare_cycle.sql` adds `cost_lines.billed_usd`,
900`billable_quantity` and `basis`, `cf_subscriptions.cycle_start`,
901`cost_reads`, `margin_days.given_unpaid_micros` and the
902`payments_live_since` setting (see [The billing cycle](#the-billing-cycle)).
903
904## Spend caps
905
906Two caps keep what g1t pays for itself bounded while billing takes no
907real money. Both are measured at **cost** (what Cloudflare and the model
908providers charge g1t), never at price. Code: `services/billing/src/budget.rs`.
909Page: sudo **Costs & margin** → **g1t's own spend** (`/costs#spend`).
910
911### What counts as g1t's own spend
912
913Every charge that settles (an agent run's model cost from `finish_run` or
914AI Gateway's settlement, sandbox time from `record_sandbox`, a build from
915`charge_feature`) is split by what paid for it and g1t's part is added to
916`g1t_spend` (day, bucket, billing account):
917
918| Bucket | What |
919| --- | --- |
920| `comped` | All of a comped account's work (flagon-io) |
921| `trial` | The trial credit's share |
922| `oss` | The open-source pool's share |
923| `given` | A free workspace's overrun past its last bit of trial |
924| `unpaid` | Charged, but with no real money behind it: Stripe's test key, or `FREE_WHILE_BUILDING` |
925
926The plan's included usage and on-demand charges count as revenue only
927with live payments; in test mode they are `unpaid`, at what the usage cost
928g1t, never what was charged. A workspace's own
929model provider costs g1t nothing and is not counted. Month-end meters
930(git, storage, scans, embeddings, the cache) are not counted here; the
931daily reconciliation covers them. Migration `0024_spend_caps.sql`
932backfills the current month from the ledger.
933
934**Why it differs from the statement.** The section is the calendar month
935so far, today included, counted as each charge settled: the model
936providers' cost and the price book's cost of sandboxes and builds. The
937statement is the range, reconciled against Cloudflare's bill, where
938sandboxes inside Cloudflare's included usage cost $0. Both count
939Cloudflare's subscriptions the same way: each day its billing cycle's share
940of the month's price (`SpendCaps.fixed_month_micros` here, the month's days
941so far). And `g1t_spend` is never wiped: spend on a workspace a testing reset
942wiped later stays here (sudo names it, `SpendCaps.reset_micros`), while the
943statement has it only where the reset kept it (`reset_costs`, given away as
944testing resets). syntaqx's $7.41 of 2026-10-02 to 10-05, reset on 10-07
945before resets kept their cost, is that case.
946
947### Caps
948
949| Cap | Variable (g1t-billing) | Default | At the cap |
950| --- | --- | --- | --- |
951| A comped account's monthly budget | `COMPED_MONTHLY_CEILING_MICROS`, or the account's own **Limit** in its terms | $150 a month | New work on the account (agents, checks, workflows, builds) is refused with "<name>'s monthly budget for g1t's own agents is used up … Staff can raise it in sudo". Runs already going finish; the per-run cap still applies to them. It lifts when staff raise the budget or the month turns (UTC). |
952| The daily breaker | `PLATFORM_DAILY_SPEND_CAP_MICROS` | $75 a day (UTC) | New agent runs on g1t's hosted models that g1t would pay for are refused until 00:00 UTC. Not paused: agents on the workspace's own model provider, checks and builds, and workspaces paying with live payments on the plan (not given by staff) or an enterprise contract. In test mode that exemption covers no one. |
953
954`0` turns either off. Cloudflare's subscriptions are read from Cloudflare
955each day (`cf_subscriptions`) and shown on the page only, accrued day by
956day; `CLOUDFLARE_FIXED_MONTHLY_MICROS` ($30) stands in until a read works.
957
958The checks are cheap: `reserve` reads today's total (one indexed sum) and,
959for a comped account, its month's comped rows. Refusals come back as
960`paused`, which the compute gate honours for every plan, internal and
961enterprise included (`packages/contracts/src/compute.ts`). The runner tells
962billing whether an agent run is on hosted models (`hostedModel` on
963`reserve`); a caller that does not say is treated as hosted.
964
965### Alerts
966
967All to `COSTS_ALERT_EMAIL` (`hey@flagon.io`), through the `EMAIL` binding:
968
969- **Comped budget**: at 50, 75, 90 and 100%, once each per account and month
970 (`budget_alerts`), checked every 15 minutes. A jump past several levels
971 sends only the highest.
972- **Breaker**: at once, from the charge that trips it; if that email fails,
973 the 15-minute cron sends it (`spend_breaker.told_at`).
974
975While the breaker is open or a comped budget is used up, every sudo page
976shows a red **Spend cap** bar.
977
978### Raising and lifting
979
980- **Raise a comped budget**: sudo → the workspace → Billing → **Terms**, set
981 **Limit $** to the new monthly budget (blank goes back to the default),
982 with a note. It applies to the next start; nothing to deploy. The change
983 is in the account's audit log.
984- **Lift the breaker for today**: sudo → Costs & margin → **g1t's own
985 spend** → **Lift for today**, with why (`admin_lift_breaker`; audit action
986 `breaker_lifted`). It resets by itself at 00:00 UTC.
987- **Change a default**: edit the variable in `services/billing/wrangler.jsonc`
988 and deploy g1t-billing.
989
990## Resetting a test workspace
991
992sudo → the workspace → **Reset billing (testing)** (`admin_reset_billing`)
993returns a workspace used for testing to how a new customer starts. It
994deletes the workspace's rows from every billing table: ledger and balance,
995plan and plan payments, limits and limit requests, trial grant, invoices,
996holds, card checks, alerts sent, price notices, month-end snapshots and
997closes, storage meters, token usage, spikes, sales records and
998notes, `workspace_costs`, its workspace margin alert and its own billing
999account. It keeps `own_counts` (what Cloudflare's bill is compared with)
1000and the audit log, which records the reset with the note, the number of
1001rows and what g1t had paid for. The workspace, its members and its
1002repositories are identity's and repos' and stay.
1003
1004**What g1t paid for is kept.** The wiped usage still happened: AI Gateway
1005still prices its model calls and Cloudflare still bills its sandboxes. So,
1006in the same batch as the deletes, the reset writes `reset_costs`: a row per
1007day and bucket the workspace had cost on (the ledger's cost, month-end
1008meters' cost, and the value the reconciliation gave it), plus one row for
1009the reset itself (bucket `''`, nothing in it) so every reset is on record.
1010`reset_at` is the same instant as the reset's `admin_actions` entry. The
1011costs run reads the rows back as the workspace's usage on their days, all
1012of it given away as **testing resets**: `models` drift compares AI
1013Gateway with the ledger's model cost plus what resets kept, the statement
1014lists it under **Given away**, and the workspace stays in **Who g1t paid**
1015with its cost given. The rows are never wiped by a later reset, and a
1016rename moves them. Re-running the analysis reads the same rows and gives
1017the same answer.
1018
1019Resets before migration 0046 kept nothing; their wiped rows are gone and
1020nothing is made up for them. The costs run finds them in the audit log
1021(`admin_actions`, action `reset`) with no `reset_costs` at the same
1022instant, and the `models` drift detail says AI Gateway's figure includes
1023usage wiped by a testing reset of that workspace on that day, rather than
1024calling it a leak. syntaqx was reset on 2026-10-07 after about $8.60 of
1025model usage from 2026-10-02 to 2026-10-07; that usage is in the 7-day
1026window until the run of 2026-10-13 and leaves it on 2026-10-14.
1027
1028Billing refuses it while `STRIPE_SECRET_KEY` is a live key, for comped
1029workspaces, and for a workspace an enterprise pays for. It then runs the
1030costs analysis again (as **Run the analysis now** does), so the margin
1031figures drop the workspace's past usage at once; if that run does not
1032finish, the page says so and the button does it.
1033
1034## Stripe
1035
1036Billing keeps what it needs from Stripe so reads never wait on it, and
1037hears of changes three ways (`webhooks.rs`, `stripe_sync.rs`).
1038
1039**API version.** Every request sends `Stripe-Version: 2025-02-24.acacia`
1040(`stripe::STRIPE_VERSION`), the version billing's field reads are written
1041for; without it Stripe answers at the account's default. Webhook events
1042come at the destination's own version: billing reads an invoice's
1043subscription from `subscription` or `parent.subscription_details.subscription`.
1044Raising the version is a code change: read Stripe's upgrade notes for every
1045field billing reads.
1046
1047**Failures.** No Stripe failure reaches a page as a 500: each payment page
1048(`page_opened`), the portal, confirmations and plan changes turn it into
1049`stripe::friendly` (Stripe's own message, never the request or a key), and
1050log the full error with the workspace. Every payment page is recorded
1051through one insert (`CHECKOUT_INSERT`), checked against the migrations by
1052`every_checkout_insert_fills_the_table`, and has an idempotency key
1053(`page/<purpose>/<workspace>/…/<10-minute bucket>`).
1054
1055**The webhook.** A destination made in Stripe's dashboard (Developers →
1056Webhooks → Add destination) with the endpoint URL
1057`https://api.g1t.sh/stripe/webhook`, in the mode of billing's key (at
1058launch, make one in live mode and put its secret). Its signing secret
1059(`whsec_…`: the destination, Signing secret, Reveal) is the billing
1060Worker's secret:
1061
1062```sh
1063cd services/billing && npx wrangler secret put STRIPE_WEBHOOK_SECRET
1064```
1065
1066Without it every event is refused with 400. After rolling the secret in
1067Stripe, put the new one; during the roll Stripe signs with both, so there
1068is no gap. The event list need not be exact: billing adds any event it
1069handles that the destination does not send (daily, or **Fix destination**
1070in sudo → Stripe), and enables it again if Stripe disabled it. It never
1071changes the secret. sudo → Stripe shows whether the secret is set, the
1072destination and its status, missing events, and the latest events.
1073Events are claimed once each in `stripe_events`; a handler that fails
1074forgets its claim, and Stripe retries.
1075
1076**What is kept, and how it stays current**
1077
1078| Kept | Where | Refreshed by |
1079| --- | --- | --- |
1080| Saved card (brand, last 4, expiry) | `accounts.card_*`, `card_synced_at` | `customer.updated`, `payment_method.*`, `setup_intent.succeeded`; forgotten when g1t sets a default card, so the next read asks once; the daily pass for cards older than 7 days |
1081| Plans | `subscriptions` | `customer.subscription.*`, `invoice.*`; a read asks Stripe at most hourly once a period is over; the daily pass for rows older than a day |
1082| Payments, refunds, disputes | ledger, `checkouts`, invoices | their events |
1083
1084**Every cron run (every 15 minutes)** replays missed events: Stripe's event
1085list from an hour before `stripe_sync.through`, oldest first, through the
1086same once-only claim. `through` moves to 5 minutes before now when all were
1087handled, back to the first failure otherwise, and stays when more than
10881,000 events were listed. Claims stuck at `handling` for 10 minutes are
1089dropped so the replay retries them. The first run reads 3 days back.
1090
1091**Daily** (`keeper::DAILY`): the destination at billing's address is
1092enabled again if Stripe disabled it and given any missing event, audited as
1093`stripe`/`webhook`; then up to 25 stale cards and 25 stale plans are read
1094again.
1095
1096**What still calls Stripe on a request**: starting a payment page, a plan
1097or a card check; opening the billing portal; settling a page the person
1098came back from; renaming a workspace (the customer's name). Nothing a page
1099view reads.
1100
1101## Tax and the card fee
1102
1103Owner decision 2026-10-08. Code: `services/billing/src/tax.rs` (what is
1104kept, the address hold), `stripe.rs` (every request's tax fields),
1105`invoices.rs`, `webhooks.rs`, `ai.rs`; migration
1106`0043_tax_and_card_fees.sql`.
1107
1108### What Stripe is asked
1109
1110Every price excludes tax (`tax_behavior=exclusive`) and carries tax code
1111`txcd_10103001` (software as a service, business use; the card fee too,
1112since a fee for paying for a sale follows the sale). Fields are valid for
1113`2025-02-24.acacia`.
1114
1115| Request | Tax | Card fee |
1116| --- | --- | --- |
1117| Checkout, plan or Security (`subscription_fields`) | `automatic_tax[enabled]`, `billing_address_collection=required`, `tax_id_collection[enabled]`, with a customer `customer_update[address]=auto` and `[name]=auto`; the subscription keeps automatic tax for every renewal | A second recurring line, *Card processing fee* |
1118| Subscription on a saved card (`saved_subscription_fields`) | `automatic_tax[enabled]`; a customer Stripe Tax cannot place fails, and the person is sent to Checkout, which asks for the address | `items[1]`, the `card_fee` product |
1119| Checkout, prepay (`prepay_fields`) | As above | By card only; none by bank transfer |
1120| Checkout, AI credit (`credit_fields`) | As above | Its own line |
1121| Checkout, card check (`card_check_fields`) | Setup mode: nothing charged, nothing taxed. `billing_address_collection=required`, and the card's address is copied onto a customer with none (`fill_address`) | — |
1122| Auto-reload (`charge_saved`) | `POST /tax/calculations` first (credit and fee as lines), the PaymentIntent for the total, then `POST /tax/transactions/create_from_calculation` with the PaymentIntent as reference; a refund reverses its share (`create_reversal`, `mode=partial`) | In the calculation and the amount |
1123| Workspace invoice, month close and threshold (`invoice_workspace`) | `automatic_tax[enabled]` on the draft; each item `tax_behavior`, `tax_code` | An item *Card processing fee*, when the default payment method is a card |
1124| Enterprise invoice (`invoice_enterprise`) | The same | Never |
1125| Products (`Stripe::product`) | Made with `tax_code`; one found without it is given it | The `card_fee` product, `metadata[g1t]=card_fee` |
1126
1127### What is kept
1128
1129A payment credits the balance with what it paid for, never its tax or fee:
1130prepay credits the page's `amount_subtotal` less the fee line
1131(`credit_prepayment`), a workspace invoice `amount_paid − tax − fee`
1132(`credit_invoice`), AI credit its credit amount, and `plan_payments` the
1133plan's invoice less its tax and *Card processing fee* lines
1134(`stripe::invoice_split`). Each payment's tax and fee are rows in
1135`tax_and_fees` (`<reference>/tax`, `<reference>/card_fee`; the enterprise's
1136account id in `workspace` for its invoices), with the PaymentIntent, so a
1137refund (`charge.refunded`) gives back the balance, tax and fee in
1138proportion (`tax::refund_split`, negative rows under `refund/<charge>/…`).
1139`workspace_invoices.fee_micros` and `tax_micros` sit beside each usage
1140invoice.
1141
1142- **Statement.** *Tax* and *Card processing fees* are their own lines per
1143 day (`StatementLine.passed_micros`), never in `charged_micros`; totals
1144 `tax_micros`, `card_fee_micros`. The CSV has a row a day for each.
1145- **Margin.** Cash never holds them, so margin is untouched. sudo → Costs
1146 shows **Tax collected** and **Card fees passed on** for the range
1147 (`OverallMargin.tax_collected_micros`, `card_fees_micros`). Tax is owed to
1148 the authorities: file it from Stripe Tax's reports, never from g1t's.
1149
1150### No address
1151
1152Stripe Tax needs a country (in the US a ZIP code, in Canada a postal code
1153or province: `stripe::address_places_customer`). Before a workspace
1154invoice is drafted, g1t checks the customer; without an address, or when
1155Stripe leaves the draft at `requires_location_inputs` or refuses with
1156`customer_tax_location_invalid`, nothing is charged:
1157`accounts.tax_address_needed_at` is set, the owners are emailed once
1158(`notify_owners`), and Billing shows **Add a billing address**. Saving
1159Invoice details with an address Stripe Tax can use clears it, as does a
1160charge that goes through. Work is not stopped for it; the limits still
1161apply. Auto-reload without an address fails like a declined card (turned
1162off, owners told). An enterprise's invoice is not sent without an address:
1163sudo → the enterprise → Invoices → **Billing address** (`admin_enterprise_address`,
1164with its tax ID; audited `billing_address`).
1165
1166### The card fee
1167
1168`card_fee_cents` grosses Stripe's fee up so the amount paid for is left
1169after it: `(amount + 30¢) / (1 − 2.9%)`, rounded up; $0.91 on $20, $1.06
1170on $25. It is worked out on the amount before tax, so Stripe's fee on the
1171tax itself (a few cents) is g1t's. It is shown before paying: the plan card
1172and pricing page (`Plan.card_fee_cents`), AI credit (*Card processing fee
1173$1.06, plus tax where it applies*), Prepay. Never on a bank transfer or an
1174enterprise's (`send_invoice`) invoice. Meters stay at cost + 20% and models
1175at the provider's price plus the agent rate (price versions in migration
11760040); the fee is passed through, not margin.
1177
1178### Tax-exempt customers and tax IDs
1179
1180g1t never sets `tax_exempt`. For a customer who sends an exemption
1181certificate, set it in Stripe's dashboard (Customers → the customer → Tax
1182status: Exempt, or Reverse charge); Billing then says so. Tax IDs come
1183from Checkout (`tax_id_collection`) or Invoice details (`set_billing_details`,
1184validated against Stripe's types in `details::TAX_ID_TYPES`); Stripe checks
1185EU VAT numbers and Stripe Tax applies a reverse charge where it should.
1186Billing shows Stripe's `verification.status`.
1187
1188### In Stripe's dashboard (not done by g1t)
1189
11901. **Settings → Tax → Get started**: turn on Stripe Tax in live and test
1191 mode.
11922. **Origin address**: Flagon, Inc.'s head office address.
11933. **Default tax code**: Software as a service, business use
1194 (`txcd_10103001`); **default tax behavior**: exclusive.
11954. **Registrations**: add each jurisdiction where Flagon is registered to
1196 collect (its home state at least; then states as thresholds are
1197 crossed, which Stripe Tax's monitoring flags; the EU's OSS and the UK
1198 if selling there). Stripe collects only where a registration exists.
11995. **Customer portal**: tax ID and address updates are already allowed
1200 (`portal_configuration`).
12016. Refund an invoice through a **credit note**, so its tax is reversed in
1202 Stripe Tax.
1203
1204## Free workspaces
1205
1206Owner decision 2026-10-08: one free workspace per person, and a free
1207workspace adds no one. Billing answers one question, `free_workspaces`
1208(`credits.rs`): which of the given workspaces are on no paid plan
1209(`plan_kind_for` is `Free`). The plan, an enterprise's terms and a 100%
1210discount (flagon-io) count as paid; with payments off nothing is free.
1211Identity asks it (`services/identity/src/paid.rs`) and refuses with
1212`payment_required`:
1213
1214| Where | Refused when |
1215| --- | --- |
1216| `create_workspace` | The person owns any free workspace. Several from before are kept (grandfathered); none can be added until each is paid for or deleted. |
1217| `add_member`, `invite_member` | The workspace is free. |
1218| `add_collaborator` | Someone outside a free workspace (a username who is not a member, or an address). Members' roles are fine. |
1219| `accept_invite`, `respond_repo_invitation` | The invite's workspace (or repository's) is free now: it waits. A sign-up with such an invite makes the account without joining. |
1220
1221`@g1t` is never counted as someone added. If billing cannot be asked, the
1222change is refused for now ("try again"), never let through. The site says
1223so first (New workspace, People, a repository's Access, from the same RPC);
1224the API and MCP pass identity's refusal on as `402`.
1225
1226## The Security and quality activation
1227
1228A second monthly subscription a workspace can hold beside the plan
1229(`Feature::Security`, `feature = 'security'` in `subscriptions`). It turns
1230on the security suite's paid features for the workspace's private
1231repositories: custom secret patterns, validity checks, delegated bypass,
1232code scanning, dependency review and the security overview. Public
1233repositories have them free; secret scanning, push protection,
1234vulnerability alerts and security updates are free everywhere.
1235
1236- **Price.** The price book's `security_activation` meter (unit
1237 `workspace-month`, `source` `list`, markup 0): 10,000,000 micros, $10,
1238 from migration `0037_security_activation.sql` with its first
1239 `price_versions` row and a public `price_changes` record. `plan()` and the
1240 `prices` RPC read it (`features::security_plan_at`); if the price book
1241 cannot be read, $10. Nothing in the web app hard-codes it. A change is a
1242 new price version, like any other: noticed on the pricing page and
1243 applied from its `effective_at` to new subscriptions. Subscriptions
1244 already running keep the amount Stripe has until they are changed in
1245 Stripe.
1246- **Stripe.** Its own subscription and its own product, tagged
1247 `metadata[g1t]=security` (the plan's is `plan`). Started from the Billing
1248 page with `subscribe` (`feature: security`) on the checked card, or
1249 through Checkout; ended with `cancel_subscription` (`feature: security`)
1250 at the period's end. Its invoices count in `plan_payments` like the
1251 plan's, as paid revenue.
1252- **Who has it.** `has_feature(workspace, security)`: on with an active
1253 subscription, with comped terms or as an enterprise's workspace, or when
1254 Stripe is not configured. The plan's allowance (`allowances.plan`) does
1255 not include it. Refusals are `PaymentRequired` with the price from the
1256 price book and the Billing page's address.
1257- **Where it is checked.** The security service, on each paid call for a
1258 private repository (`suite::entitled`) and before using custom patterns
1259 in a push (`patterns_for`). When billing cannot be reached it is taken
1260 as off: a paid feature waits rather than running unpaid.
1261- **Fixes.** "Fix with g1t" runs g1t's agent, charged as agent usage, never
1262 to the activation.
1263- **Sales figures.** MRR in sudo counts `feature = 'plan'` only; the
1264 activation's subscriptions are not in it yet.
