Why Stripe Belongs in Your SaaS MVP (Not “Later”)
Without billing in v1, you never test willingness to pay. In 2026, Stripe billing for SaaS MVPs is the default: Checkout for fast launch, Customer Portal for self-serve plan changes, webhooks for entitlements.
Week-One Stripe Scope
- One or two subscription prices (monthly; annual optional)
- Stripe Checkout session from your Next.js API route
- Webhook handler:
checkout.session.completed,customer.subscription.updated - Map
stripeCustomerIdandsubscriptionStatuson your user/org record - Customer Portal link in account settings
What to Defer to v2
- Usage-based metering (unless core to pricing)
- Multi-currency tax automation (Stripe Tax when revenue justifies)
- Complex seat proration rules
Common Founder Mistakes
- No webhook idempotency → duplicate entitlements
- Trusting client-side payment state instead of server webhooks
- Skipping test mode fixtures before production keys
