Stripe payment integration into your product

I make Stripe payments that just work: you take payments, run subscriptions and calculate payouts without late-night debugging of edge cases. I don't start from a template but from your product and business model, so I first talk through all scenarios: one-time payments, recurring plans, trial periods, proration on plan changes, usage-based pricing, coupons and taxes. Then I implement it completely and hand over a scheme your accounting can reconcile without questions.

Most integrations break on what happens after the payment button is clicked, so I make webhooks the source of truth. I verify event signatures, make every handler idempotent and check payment intents against your database so duplicate or resent events don't charge anyone twice or leave an order hanging. I add strong authentication and 3-D Secure the way payment systems expect, and cover refunds, partial refunds, disputes and chargebacks so support doesn't have to guess.

For marketplaces I set up Connect: seller onboarding, payment splitting, fund holds and releases, payouts on schedule with clear reporting. I deliver everything with tests, secret keys don't leak to the client, and the code comes with brief docs.
