Yes. An AI coding agent can scaffold subscription billing, including products, checkout, customer records, webhooks, account status, and tests. Production billing still requires human review because payment events are asynchronous and directly affect money and customer access.
Give the agent a bounded design brief:
- Plans, billing periods, trials, upgrades, downgrades, cancellations, and refunds.
- Hosted checkout or payment flow and the return path.
- Subscription states and the entitlement granted by each state.
- Webhook signature verification, duplicate handling, retries, and idempotency.
- Failed-payment recovery, invoices, customer self-service, and audit records.
- Test-mode credentials, secret storage, deployment boundaries, and rollback.

For a Stripe implementation, Stripe's official documentation says subscription activity is asynchronous and should be handled with webhooks. Verify signatures, store the identifiers and state needed for access decisions, and guard against duplicate events. Test successful and failed payments, delayed and replayed webhooks, checkout abandonment, plan changes, expired trials, and cancellation.
Treat the payment provider as the authority for payment state and maintain an explicit mapping to application entitlements. A human should review security, tax, accounting, privacy, and regional obligations before launch; this page is engineering guidance, not legal or tax advice.
