Stripe app development with scoped integration, not guesswork

Payments are where MVPs stall: Checkout sessions, webhooks, test mode, failed cards, and subscription lifecycle. Lab Twelve builds Stripe wiring as scoped work—often Business App or MVP Sprint plus Stripe add-on when complexity grows. We run Lab Twelve on Stripe ourselves, so the integration patterns are production-tested, not tutorial copy. Webhook idempotency and test scenarios are part of done, not stretch goals.

FAQ

Questions for this build type

Is Stripe an add-on or included?

Business App includes Stripe-ready hooks. Full billing flows often add the Stripe billing add-on or MVP scope.

Do you use Stripe Checkout or Elements?

Checkout for speed unless scope demands embedded Elements.

Who owns the Stripe account?

You do. We wire the integration and document env vars.
