Payment Gateway Integration

A payment button that works during a demo often breaks in production the first time a card is declined, a webhook arrives out of order, or a customer's bank flags a transaction for review. Payment Gateway Integration Services exist specifically to handle these edge cases properly, not just the happy path where every payment succeeds cleanly.

For Indian businesses, a Razorpay integration typically covers UPI, cards, netbanking, and wallets in one build, along with the specific webhook events Razorpay sends for successful, failed, and refunded payments — missing proper webhook handling is one of the most common reasons an order shows as unpaid in a business's system despite the customer being charged.

For businesses billing internationally or wanting subscription billing, Stripe covers multi-currency processing, recurring billing, and a more developer-friendly API than most alternatives — but it also requires careful handling of Strong Customer Authentication requirements for European customers, which a rushed integration frequently gets wrong.

bizOversal treats webhook handling and failure states as core requirements from day one, not an afterthought bolted on after a client reports a mismatch between what Razorpay or Stripe recorded and what the business's own order records show.
