yarn mercato module add @dainamite/billing@0.19.0 --allow-third-party && yarn generate && yarn db:migrate
Or with create-mercato-module:
npx create-mercato-module install @dainamite/billing@0.19.0 && yarn generate && yarn db:migrate
In the admin, open Roles (/backend/roles) and give its 19 permissions to the roles that need them.

When to use

Use when you charge subscriptions or metered usage and want draft invoices in the app before anything is posted.

When not to use

It does not replace your accounting system: it prepares invoices for a person to approve.

What it adds

17 admin pages, starting at /backend/billing/accounts.
10 database tables.
32 API routes.
2 background workers.
10 events other modules can react to.
19 permissions to give to roles.

Readme

This is the author's README. To install, use the steps in Install.

The catalog tests those steps. Install notes in the README may be out of date.

@dainamite/billing

Lightweight recurring-billing engine for Open Mercato applications.

Collects items to charge (one_time, recurring, usage), runs a scheduled Bill Run that calculates totals and produces draft invoices in @open-mercato/core/sales, and waits for human approval before posting. It does not replace your accounting system — it prepares billing data and hands drafts to a human.

Status

Built — publishing soon. Schema, ACL, tenant setup, the Bill Run engine, usage rating, the full admin UI, and the @dainamite/cpq-billing-connector companion are all in place. The package is not yet on npm; until it publishes it is available inside the dainamite-core monorepo.

See specs/implementation/xd-249-billing-spec.md for the full implementation plan.

What's inside

Billing Items — the charge backlog (one_time, recurring, usage), each scoped to a Billing Account with a bill start/end window.
Bill Runs — a background worker (@open-mercato/queue) that, on a schedule or on demand, rates usage, sums the due items for the period, and writes draft invoices into @open-mercato/core/sales. Runs are idempotent and tenant-locked; stale runs are reaped by a worker.
Draft invoice approval — invoices land in draft; a human reviews and posts them (a guarded ACL action) before they leave draft.
Usage rating — metered items are rated at run time from ingested usage.
Admin UI under /backend/billing/* — Accounts, Items, Bill Runs, Invoices (list + detail pages).
Commands for every write (accounts / items / runs / invoices / usage), validated with Zod.

Installation

@dainamite/billing is an Open Mercato module. Install it and register it in your host app's src/modules.ts:

yarn mercato module add @dainamite/billing   # installs + registers (once published to npm)
# …or: yarn add @dainamite/billing  then add { id: 'billing', from: '@dainamite/billing' }

yarn generate
yarn mercato db migrate

Required Open Mercato modules

sales (draft invoices are written there), @open-mercato/queue (Bill Run worker), and @open-mercato/events (lifecycle events consumed by the connector). Engines: Node ≥ 24.

CPQ integration

To bill subscriptions sold through CPQ, add @dainamite/cpq-billing-connector — it subscribes to CPQ subscription lifecycle events and creates/updates Billing Accounts and Items automatically. Register it after both cpq and billing.

Distribution rules (per SPEC-001)

peerDependencies, never dependencies for @open-mercato/* and sibling @dainamite/* — one shared instance in node_modules.
No ORM relations across packages — cross-module references are FK strings; draft invoices are created through the sales service / events, not a direct relation.
Ships its own migrations under src/modules/billing/migrations/.
Ships src/ (types) + dist/ (runtime JS); no .d.ts emitted.
