Description
01 / Overview
What this service delivers
Capturing a payment is the easy part. The real trouble arrives later: duplicate webhooks, UPI collect payments that confirm several minutes after the customer has left, and refunds that never reach the books. We integrate a UPI-capable payment gateway using idempotent order creation, signature-verified webhooks and a nightly reconciliation that compares gateway settlements with your own records. Failed payments can be retried without side effects, and mandates are handled wherever you bill on a recurring basis.
