Payment Gateway Integration
Payment integrations are the most critical — and the most unforgiving — code in any commerce product. We build payment flows that are secure, PCI-compliant, handle edge cases correctly, and reconcile reliably.
// Key benefits
What makes this service valuable
Multi-gateway expertise
Stripe, Razorpay, PayU, Cashfree, and PayPal. We choose or integrate your preferred gateway with proper webhook handling, idempotency, and reconciliation.
Subscription and billing logic
Recurring billing, free trials, proration, upgrades, downgrades, and cancellation flows — implemented correctly with Stripe Billing or equivalent subscription management.
Secure and PCI-compliant
Card data never touches your servers. We use hosted fields, payment elements, and tokenisation to achieve PCI SAQ A compliance while maintaining full UX control.
// Details
Payments that collect money and keep it
Payment integration is about more than a checkout form. Idempotency keys, webhook signature verification, retry handling, and reconciliation are what separates a production-quality payment implementation from a prototype.
We implement payment flows with explicit handling for every failure mode: card declines, network errors, webhook delivery failures, and dispute management. Every payment event is logged and reconciled.
// What this includes
- Stripe / Razorpay / PayU integration
- Payment intent and checkout session flows
- Webhook handling with signature verification

// FAQ
Common questions about payment gateway integration
Which payment gateway do you recommend for Indian businesses?+
Razorpay or Cashfree for domestic-primary businesses — both offer excellent support for Indian payment methods (UPI, NEFT, wallets) alongside cards. Stripe is better for international-primary businesses. Many businesses use both.
How do you handle failed payments and subscription dunning?+
We implement smart retry logic (exponential backoff with jitter), email dunning sequences, and grace period management. Stripe Billing includes this natively; for other gateways we implement equivalent logic.
