Payment Gateway Integration (Stripe, Razorpay)

Payment integrations must be flawless — failed payments mean lost revenue. We implement payment systems that handle edge cases gracefully: failed charges, card expiration, subscription upgrades/downgrades, proration, tax calculation, and webhook reconciliation. Our integrations are PCI-compliant and battle-tested.

• Stripe Integration — Implement Checkout, Elements, Billing (subscriptions), Connect (marketplace), and Invoicing with full webhook handling.
• Razorpay Integration — Set up Standard/Route for marketplaces, Subscriptions, and Smart Collect for India-focused businesses.
• Subscription Billing — Build complex subscription models with trials, tiers, usage-based pricing, and automated dunning for failed payments.
• Marketplace Payments — Implement multi-party payments with platform fees, seller payouts, and split payments using Stripe Connect or Razorpay Route.
• Tax & Compliance — Integrate tax calculation (Stripe Tax), generate invoices, and ensure PCI DSS compliance throughout the payment flow.
• Revenue Recovery — Implement smart retry logic, dunning emails, card updater integration, and analytics for reducing involuntary churn.

We integrate with Stripe (primary for global) and Razorpay (primary for India) using official SDKs. Webhook processing with proper idempotency and ordering. Frontend payment forms use Stripe Elements or Razorpay Checkout for PCI compliance. All implementations include comprehensive payment event monitoring.

SaaS products implementing subscription billing, e-commerce platforms needing checkout flows, or marketplaces requiring multi-party payments. Whether you're adding payments for the first time or migrating between payment providers, we deliver robust, compliant payment integration.
