Payments & Billing

Payment Gateway Integration

Accept payments seamlessly. From Razorpay and Stripe to UPI and subscription billing — we integrate payment solutions that convert customers and keep your revenue flowing.

Every abandoned cart, every failed transaction, every confusing checkout flow is revenue lost. In India's rapidly evolving digital payments landscape — where UPI processes over 10 billion transactions monthly — having a robust, reliable payment integration isn't optional. It's the difference between a business that grows and one that stagnates. At Fillicore Technologies in Salem, we integrate payment gateways that maximize conversion rates while ensuring complete security and compliance.

Whether you're a Salem-based e-commerce store accepting UPI payments, a SaaS company managing recurring subscriptions, or a marketplace handling split payments between vendors — our payment integration services cover every scenario. We work with India's leading gateways and international providers to give your customers the payment experience they expect.

Payment Gateways We Integrate

We integrate with India's top payment providers and international gateways.

Razorpay

India's most popular payment gateway. UPI, cards, net banking, wallets, EMI, and international payments. Excellent dashboard, webhook reliability, and developer-friendly APIs. Supports payment links, subscriptions, and route (split payments).

Stripe

The global standard for online payments. Best-in-class developer experience, 135+ currencies, advanced fraud detection with Radar, and powerful subscription management with Stripe Billing. Ideal for SaaS and international businesses.

Cashfree & PayU

Cashfree excels at payouts, marketplace settlements, and auto-collect. PayU offers competitive rates for high-volume merchants. Both support UPI AutoPay for recurring payments — essential for subscription businesses in Tamil Nadu.

Advanced Payment Capabilities

Beyond basic checkout — we implement sophisticated payment workflows.

A

Subscription Billing

Automated recurring payments with trial periods, plan upgrades/downgrades, proration, dunning management for failed payments, and GST-compliant invoicing. Perfect for SaaS products and membership-based businesses in Salem.

B

Split Payments & Marketplace

Route payments to multiple vendors automatically. Commission deduction, vendor settlements, and escrow-like flows for marketplace platforms. Razorpay Route and Stripe Connect handle the complexity of multi-party payments.

C

Refund & GST Automation

Automated refund processing with webhook-driven status updates. GST-compliant invoice generation with proper HSN codes, GSTIN validation, and e-invoicing integration. Multi-currency support with automatic exchange rate handling.

Payment Integration Features

Every payment integration we build includes these essential capabilities.

PCI DSS Compliance

Tokenized payment flows ensure card data never touches your servers. Hosted checkout pages, secure iframes, and encrypted webhooks keep your integration PCI compliant without the audit burden.

Webhook Reliability

Idempotent webhook handlers with signature verification, retry logic, and dead letter queues. Never miss a payment confirmation, refund notification, or subscription event.

Multi-Gateway Fallback

Automatic failover between payment gateways. If Razorpay is down, transactions route to Cashfree seamlessly. Your revenue never stops flowing, even during gateway outages.

Frequently Asked Questions

Which payment gateway is best for India?

Razorpay is the most popular choice for Indian businesses with excellent UPI support, competitive pricing (2% per transaction), and a developer-friendly API. Cashfree is great for payouts and marketplace splits. For international payments, Stripe offers the best global coverage. We often integrate multiple gateways for redundancy and optimal coverage.

How do you handle PCI compliance?

We never store card data on your servers. By using tokenized payment flows through Razorpay or Stripe's hosted checkout, your application achieves PCI DSS compliance without the complexity of a full audit. We implement secure webhooks, encrypted communication, and follow all gateway-specific security guidelines.

Can you integrate UPI payments?

Yes. UPI is India's most popular payment method with over 10 billion monthly transactions. We integrate UPI through Razorpay, Cashfree, or direct NPCI integration — supporting QR code payments, UPI intent flows, and collect requests. We also handle UPI AutoPay for recurring subscriptions.
