About this Gig
Got a Next.js app that needs payments and authentication but you're stuck on the implementation? I specialize in integrating Stripe and Clerk into Next.js applications, giving you a complete, production-ready payment and auth system in 13 days.
Stripe and Clerk are the go-to stack for modern SaaS products but getting them wired together correctly with webhooks, subscription handling, and protected routes takes real expertise. I have done this dozens of times and will deliver a clean, battle-tested integration.
What I Deliver
- Clerk authentication sign up, sign in, social logins (Google, GitHub), user sessions
- Protected routes and middleware only authenticated users access paid features
- Stripe Checkout one-time payments and subscription plans (monthly/annual)
- Stripe Customer Portal users can upgrade, downgrade, or cancel subscriptions
- Stripe webhooks real-time sync of payment events to your database
- Supabase or PostgreSQL integration store user plan/subscription status
- Full TypeScript code, clean architecture, ready for production deployment

FAQ
Do you work with the Next.js App Router?
Yes — all integrations are built with Next.js 14+ App Router, server components, server actions, and middleware.
Which database do you support for storing subscription data?
I primarily use Supabase and PostgreSQL with Prisma, but can adapt to MongoDB or any database you use.
What if I already have auth set up with NextAuth?
I can either migrate to Clerk or add Stripe billing alongside your existing NextAuth setup — just mention it when you order.
Do you handle webhook security?
Yes. All Stripe webhooks are verified with signature validation to prevent spoofed requests.
