Your users like the product, but you cannot charge them yet, or billing is handled by hand. I add Stripe or Paddle subscriptions to your existing Next.js or Node.js app: plans, free trials, coupons, a customer billing portal, and webhooks that keep your database in sync. You add your API keys yourself, so I never handle your live secrets. Everything is tested in test mode before it goes live.

Starter, checkout ($150, 3 days): Stripe Checkout for one plan or a one-time payment, success and cancel pages, receipt email

Standard, subscriptions ($400, 6 days): Up to 3 plans, monthly and yearly, trials, coupons, customer portal, webhooks syncing plan status

Advanced, full billing ($800, 10 days): Standard plus usage or seat-based billing, plan limits in the app, invoices, admin billing view

PayPal as a second gateway

Usage-based billing on Standard

Faster delivery

Repo access, a Stripe or Paddle account in your name with test keys added by you, and your plan list and prices. You own all code and accounts from day one.
