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.
01 — Gateways
We integrate with India's top payment providers and international gateways.
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).
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 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.
02 — Capabilities
Beyond basic checkout — we implement sophisticated payment workflows.
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.
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.
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.
03 — Features
Every payment integration we build includes these essential capabilities.
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.
Idempotent webhook handlers with signature verification, retry logic, and dead letter queues. Never miss a payment confirmation, refund notification, or subscription event.
Automatic failover between payment gateways. If Razorpay is down, transactions route to Cashfree seamlessly. Your revenue never stops flowing, even during gateway outages.

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.
