Details

Converts an anonymous cart into a real tenant: it **creates the organization and the user at this point**, captures the billing details, and places an immutable order. Availability is **re-verified live** against the registrar first, so a name taken while the customer was typing aborts the whole call (`409`) with nothing created. Tax is computed against `billing.country` (§2.8). **It never takes a card, and what it does next depends entirely on the total.** The response is `{order_id, org_id, next}`: - `"payment"` — the order has something to pay and is left `pending_payment`. Taking payment is the authenticated step that follows, because a brand-new organization has no payment mandate on file. - `"done"` — the total is **zero** (a free trial, a zero-priced plan, a 100% discount), so the order is **settled and provisioned inside this call**: a zero `Payment` is recorded, the order becomes `paid`, and the fulfilment workflow starts. No gateway is contacted — a brand-new organization has none to resolve, and there is nothing to charge. Owner ruling 2026-08-09: *a free trial takes no card and starts immediately.* ⛔ Between that ruling and 2026-08-12 this endpoint answered `"done"` and performed **none** of it — the order stayed `pending_payment` with no payment, no fulfilment and no workflow, so the customer was told their trial had started and no site was ever built. Anything that keys off `next` should key off it alone; the order state now follows it. **Idempotent on the cart.** A double-submit — concurrent or an hour later — produces one organization, one user and one order; the repeat returns the same ids. There is no `Idempotency-Key` header to send: the cart token *is* the key. If the email already has an account the call is refused with `409` and nothing is created: the purchase must be completed signed in, so that an unauthenticated request can never attach an order to somebody else's tenant. The cart stays open.
