Indian customers expect to pay their way: UPI, debit and credit cards, net banking, wallets, EMI and often cash on delivery. A payment gateway connects your website or app to these methods. Choosing and integrating it well affects conversion, cash flow and customer trust.
How a Payment Gateway Works
- The customer chooses a payment method at checkout.
- The gateway securely collects payment details or redirects to UPI or the bank.
- The payment is authorised and confirmed.
- Your website receives the confirmation and updates the order.
- Funds are settled to your bank account after a settlement period.
Choosing a Gateway
Compare providers on:
- Payment methods supported: UPI, cards, net banking, wallets, EMI, pay later.
- Transaction pricing, by method.
- Settlement time.
- Success rates and reliability.
- Onboarding and KYC process.
- Dashboard, refunds and reporting.
- Support quality.
- International payments, if you need them.
Payment gateways and aggregators in India operate under RBI regulations, so choose an established, authorised provider.
Integration Essentials
Server-Side Verification
Never trust only the browser. Confirm every payment on the server using the gateway's signature verification or status APIs.
Webhooks
Gateways send webhook notifications when payments succeed, fail or are refunded. Handle them to keep order status accurate even if the customer closes the browser.
Idempotency
Ensure the same payment is not processed twice due to retries or duplicate notifications.
Refunds
Support full and partial refunds from your admin panel.
Reconciliation
Match gateway settlements with orders and bank credits regularly.
Security
Card data should be handled by the gateway, not stored on your servers. RBI rules restrict storing card details and require tokenisation for saved cards.
UPI Considerations
UPI is the most popular method for many Indian shoppers. Offer intent-based flows on mobile so customers can pay with their preferred UPI app in a tap. Show QR codes on desktop.
Cash on Delivery
COD remains common, especially outside large cities. Reduce risk with:
- Order confirmation by WhatsApp or call.
- COD limits on high-value orders.
- Incentives for prepaid payment.
- Tracking return-to-origin rates by pincode.
"Every extra step in checkout is a chance for the customer to leave."
Subscriptions and Recurring Payments
For subscriptions, use mandates such as UPI Autopay or card e-mandates, which follow RBI's rules for recurring payments.
Testing Before Launch
- Test every payment method in sandbox mode.
- Test failures, timeouts and cancellations.
- Test refunds.
- Verify webhook handling.
Common Questions
How long does gateway onboarding take? It depends on the provider and your business type. Expect to submit business documents, bank details and website policies for KYC. Having refund, shipping, privacy and terms pages ready speeds up approval.
What is a payment success rate, and why does it matter? It is the share of attempted payments that succeed. Failures happen due to bank downtime, wrong details or authentication issues. A gateway with good success rates and smart retry options means fewer lost sales.
Should we use more than one gateway? Larger businesses sometimes use two gateways to route payments and stay online if one has issues. For most small and medium stores, one reliable gateway is enough.
How quickly do we receive money? Settlement periods vary by provider and plan, typically within a few working days. Some providers offer faster settlement for an additional fee.
Do we need a separate bank account? Not necessarily, but a dedicated current account makes reconciliation simpler.
