Stripe Payments Hardening · $149
One bad webhook can give everyone a free subscription. Let's make sure yours can't.
For apps built with Lovable, Bolt, Cursor or Claude Code that take payments through Stripe Checkout or Billing. I review and fix the webhook and subscription logic in your code, then replay the edge cases in Stripe test mode to prove it holds.
What you get
- Webhook signature verification and idempotent event handling, so retries never double-grant or double-charge
- Subscription state mapped correctly: trialing, active, past_due, canceled, plus upgrades and downgrades
- Failed-payment handling: access rules and dunning emails via Stripe's built-in emails or your email provider
- 10 edge cases replayed in test mode (duplicate events, out-of-order events, refund, dispute, card decline, cancel at period end and more), with results
- Changes delivered as a pull request with a short written summary and a screen recording, within 5 business days of access
Test mode only: I never need your live secret key. You give me repo access and a test-mode restricted key. Stripe Connect marketplaces and custom tax setups are out of scope and quoted separately.
Refund policy
Not delivered within the stated time after you send everything the intake asks for? Full refund. Your code, data and findings stay private, and I never use credentials beyond the agreed scope.
