I will integrate stripe subscription billing and webhooks into your app
Muhammad Anas
About this gig
Most teams do not lose money on pricing. They lose it on billing edge cases.
Failed payments nobody retries. Proration that overcharges annual customers. Webhooks that fail silently for weeks before anyone notices. Checkout is the easy part. What breaks is everything after it.
WHAT I BUILD
Stripe Checkout and subscription plans. Trials and trial to paid conversion. Upgrades and downgrades with correct proration. Customer portal for self serve plan changes and invoices. Usage based metering. Failed payment retry and dunning. Pricing and plan change screens too.
WHY IDEMPOTENCY MATTERS
Stripe retries delivery and can send events out of order. A handler that is not idempotent will eventually charge someone twice. I use an event log with a uniqueness constraint on event ID, so a repeated delivery cannot create a duplicate charge or subscription record.
STACK
Node.js, NestJS, Express, Next.js, TypeScript, PostgreSQL, MySQL, Redis, Prisma, TypeORM. I work in your existing codebase or build the billing layer from scratch.
Message me with your pricing model and stack before ordering and I will tell you which package fits.

I build the parts of web applications where mistakes are expensive: subscription billing, APIs that hold up under load, real-time features, and AI capabilities added to products that already work.
2 years building production SaaS in TypeScript — Next.js, NestJS, PostgreSQL, Redis, Stripe. I've shipped multi-tenant platforms with role-based permissions, idempotent payment webhooks, and concurrency-safe transactions.
I ask questions before writing code, and I tell you when an approach won't work instead of building it and letting you find out later.
FAQ
Do I need a Stripe account already?
Yes, and it should be activated. I can guide you through setup, but the account and its bank details have to be yours.
Can you work in my existing codebase?
Yes, and that is usually the better option. I read the existing patterns and match them rather than bolting on something that looks foreign.
What about tax and VAT?
Stripe Tax can handle calculation and I can enable it. I am not a tax advisor, so confirm your obligations with an accountant.
Can you migrate me from Paddle, Chargebee or Lemon Squeezy?
Yes, but migrations need a real scope conversation first. Message me and I will send a custom offer..
Will you handle the frontend too?
Yes. Pricing page, checkout flow, plan change screens and billing settings in React or Next.js.
What if my pricing model is unusual?
Message me before ordering. Seat based, usage based, hybrid and metered models are all workable, but the scope differs a lot between them.
