Overview

About this service

Taking a payment is the easy part. What breaks in production is everything after: a webhook that arrives twice, a UPI collect request the customer completes ten minutes later, a refund that never reaches your ledger. We integrate a payment gateway properly, with idempotent order creation, signature-verified webhooks, and a reconciliation job that compares the gateway settlement against your own records daily. Failed payments retry cleanly rather than silently losing the order. Subscriptions and mandates are included where you need them.
