Scope
What this service can cover
Payment issues can come from gateway misconfiguration, callback failures, broken checkout forms, validation mismatches, or changes in the surrounding application flow.
We review how the payment request is built, how the provider responds, whether callbacks and webhooks are reconciling correctly, and whether the customer-facing checkout path is failing before or after payment.
Because payment faults directly affect revenue, these issues usually need fast review and a cautious fix path.
