Repair the gap between checkout completion and the access your customer should receive.

DELIVERABLES Diagnosis and source changes for one existing JavaScript or TypeScript checkout-to-entitlement flow; webhook-signature validation; relevant duplicate-event handling; test-mode evidence and a deployment handoff.

PROCESS We define the expected account or subscription state, reproduce the issue in Stripe test mode, repair the agreed path and verify resulting application access.

SCOPE One existing app, one week and two correction rounds. No live charges or refunds are part of testing. Tax advice, new subscription business rules, extensive billing migrations and unrelated backend work are separate.
