E-commerce & Payment Gateway Integration
Conversion-focused e-commerce builds and robust payment integrations — Razorpay, Stripe, PayU, UPI — with PCI-aware architecture and reconciliation.
Whether you are selling event tickets, merchandise, or a full product catalogue, the difference between a good and a poor checkout is measured directly in revenue. ZebIQ builds e-commerce platforms and integrates payment infrastructure with an engineering-first approach: fast storefronts, frictionless checkouts, and payment flows that handle failure gracefully.
We work across the Indian and international payment landscape — Razorpay, PayU, Cashfree, Stripe, PayPal — including UPI intent flows, payment links, subscriptions, EMI options, and international cards with dynamic currency. Our integrations are built defensively: idempotent order creation, webhook verification, automatic retry handling, and reconciliation reports that make your finance team's month-end painless.
For event clients specifically, we handle the hard cases: flash-sale ticket releases with inventory locking, partial refunds against cancellation policies, and split settlements between organisers and vendors.

Frequently asked
It depends on your transaction mix, settlement timelines, and international requirements. We typically recommend a primary gateway plus a fallback, and we benchmark success rates for your specific card/UPI mix during the pilot rather than relying on published claims.
Our order pipeline is idempotent and webhook-driven: a payment is only confirmed on verified gateway callback, stuck transactions are auto-reconciled via status APIs, and customers see honest, actionable states instead of silent failures.
We architect so card data never touches your servers — using gateway-hosted fields and tokenisation — which keeps you in the lightest PCI DSS scope (SAQ A). We also follow RBI tokenisation requirements for the Indian market.
