What this service delivers
Accepting a payment is the easy part. The real problems come later: duplicate webhooks, UPI collect requests that confirm several minutes after the customer has left, and refunds that never reach your accounts. We integrate a payment gateway that supports UPI, with order creation that cannot accidentally run twice, signed webhooks that are verified, and a nightly job that compares the gateway's settlements with your own records. Failed payments can be retried cleanly, and recurring mandates are set up wherever you bill on a schedule.
