How do I add Stripe subscription tiers?

Click the Stripe integration to OAuth in. Create your products in the Stripe dashboard (Free, Pro, Team), grab the price IDs, and prompt: "Wire up subscription checkout with these three price IDs." The AI scaffolds the checkout route, webhook handlers, and portal redirect.

How do I gate features by plan?

Plan gating has to live on the backend, not the UI. Every API route that does something paid checks the user's current plan from the profiles table before running. Hiding the button on the frontend is a courtesy; anyone can call the API directly otherwise.

What about cancellations and refunds?

Listen for customer.subscription.updated (cancellation scheduled) and customer.subscription.deleted (period ended). Don't downgrade on the first event - they paid through the period. The Stripe customer portal handles cancellation UX so you don't build it.

How do I handle GDPR data deletion for cancelled users?

Add a "delete my account" button that triggers a cascading delete across profiles, usage, and any user-owned records. Real deletion in Postgres, not soft-delete. Schedule a job to also delete user data N days after subscription cancellation if you want to be aggressive about retention.

How long does it take to ship?

Two to three hours from blank to a working flow: signup, upgrade to Pro via Stripe Checkout, hit a usage limit on Free, see the customer portal work. Production-polish (custom emails, analytics, onboarding) is a weekend.

Why generate it instead of buying it.

“

The wiring is what takes the time, not the product. Auth, Stripe webhooks, plan gating, and the customer portal eat a weekend even with a starter template. Generate them in two hours and spend the saved time on the thing users actually pay for.

“

You own the full Next.js codebase. When you outgrow the scaffold (custom pricing experiments, enterprise quotes, usage-based billing), you extend the same code instead of fighting a SaaS-builder platform's limits.
