Overview

This starter targets involuntary churn. It wires Stripe webhooks to detect failed payments, provides a self‑serve billing portal for customers to update cards, and sets you up for dunning workflows to recover revenue automatically.

It balances correctness and speed so you can ship confidently while capturing more retained MRR.

What’s included

  • Next.js 14 + TypeScript
  • Stripe webhook (invoice/subscribe events)
  • Billing Portal endpoint to update payment methods
  • Prisma + SQLite for event logs and subscriptions
  • Cron‑like API placeholder for dunning

Separation keeps webhook concerns stateless with idempotency and signature checks, while UI stays focused on plan selection and account state.
