Next.js + Stripe
for SaaS founders.
Next.js + Stripe is the canonical SaaS billing stack — server actions for checkout, webhooks for subscription state. For SaaS founders: Subscription patterns, customer portal flows, webhook idempotency.
This stack, applied to you.
For SaaS founders, Next.js + Stripe is the canonical billing stack. Server actions handle Checkout creation, webhooks update subscription state, and Stripe Customer Portal gives self-service to customers. The whole billing surface area can be implemented in 1-2 weeks for a typical SaaS. Stripe Tax handles compliance once you register.
SaaS founders-specific gotchas
- Webhook signature verification is mandatory — never trust the body
- Idempotency: webhooks deliver at-least-once, handlers must be idempotent
- Customer Portal handles cancellation, plan changes, invoices — use it
- Tax handling: Stripe Tax requires registration in each jurisdiction
- Trial logic should live in Stripe (not your DB) — fewer race conditions
A SaaS founder ships a 3-tier subscription product on Next.js + Stripe in 8 days. Customer self-service (cancellation, plan changes) handled entirely by Stripe Customer Portal. Total billing engineering time: <1 week.

How do we handle dunning?
