ZebIQ Technology

E-commerce & Payment Gateway Integration

Conversion-focused e-commerce builds and robust payment integrations — Razorpay, Stripe, PayU, UPI — with PCI-aware architecture and reconciliation.

The difference between a thriving e-commerce business and a stalled one is measured directly in revenue — and that difference lives in your checkout. ZebIQ builds conversion-focused storefronts and integrates robust payment infrastructure across Razorpay, Stripe, PayU, UPI, and international gateways. Fast, frictionless, resilient, and PCI-aware. Whether you're selling event tickets, merchandise, or a full catalogue, we engineer payment flows that handle scale, failure, and reconciliation without compromise.

Why Payment Integration Matters

A seamless checkout isn't a luxury—it's the single largest lever on conversion. Every friction point—slow load times, unclear error messages, failed retries, or missing payment options—costs you revenue.

We build e-commerce platforms with an engineering-first approach:

  • Fast, mobile-first storefronts that load in milliseconds
  • Intelligent multi-gateway routing with automatic fallback if a payment processor degrades
  • Idempotent order pipelines that never double-charge or lose transactions
  • Signed webhook verification and automatic reconciliation so your finance team doesn't spend days hunting mismatches
  • UPI, subscriptions, EMI, international cards, and dynamic currency all in one system

For event clients, we handle the hard cases: flash-sale ticket releases with inventory locking, partial refunds against cancellation policies, and split settlements between organisers and vendors.

Multi-Gateway Intelligence

Your customers won't always prefer the same payment method. One cohort lives on UPI; another uses international cards; a third expects COD or buy-now-pay-later.

We architect gateway selection to be intelligent and invisible to the user. Route based on card type, geography, and historical success rates. Fall back instantly if a processor is slow or down. Monitor success metrics in real time and rebalance traffic to the gateways performing best for your mix.

Supported integrations include Razorpay, PayU, Cashfree, Stripe, PayPal, plus UPI intent and collect flows optimised for the Indian market.

Core Capabilities

High-Conversion Storefronts

Our Process

  1. 1. Commerce Audit & Architecture

    We map your catalogue, pricing rules, tax requirements, and settlement flows, then design the right platform and gateway mix for your scale and market.

  2. 2. Build & Integrate

    Storefront development and gateway integration with comprehensive sandbox testing—success paths, failures, timeouts, refunds, and edge cases.

  3. 3. Reconciliation & Compliance

    Settlement reports, GST-ready invoicing, RBI tokenisation compliance, and webhook monitoring configured before go-live.

  4. 4. Load Test & Launch

    Simulated peak-traffic runs against the full checkout path, real-time monitoring, and a guided production launch with instant incident response.

Common Questions

Which payment gateway should we choose?

The answer 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.

How do you handle failed or stuck payments?

Our order pipeline is idempotent and webhook-driven: a payment is only confirmed on a verified gateway callback, stuck transactions are auto-reconciled via status APIs, and customers see honest, actionable states instead of silent failures.

Is the integration PCI compliant?

Yes. 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.

Can you handle subscriptions and recurring billing?

Yes. We support recurring billing mandates, subscription lifecycle management, failed renewal handling, and dunning workflows across Razorpay, Stripe, and other major gateways.

What about international payments and multi-currency?

We support international cards, dynamic currency conversion, and cross-border settlement via Stripe and PayPal. We handle currency detection, exchange rates, and tax compliance per region.

How do you ensure real-time reconciliation?

We build automated reconciliation pipelines that match gateway settlement reports to your order database hourly, flag discrepancies, and generate audit-ready reports for your finance team.
