Which payment gateway is right for you?
The right gateway depends on who you sell to. If your buyers are in India, Razorpay or PayU are strong defaults because they support UPI, netbanking, wallets, and EMI natively, which is how most Indian shoppers prefer to pay. If you sell internationally, Stripe and PayPal handle global cards and currencies smoothly. Many stores run a combination so every customer has a familiar option.
Cash on delivery deserves special mention. For a large share of Indian shoppers, COD is still the trust mechanism that gets the order placed. We can wire COD alongside online payment so you capture both the prepaid and the cautious buyer. The goal is simple: never lose a sale because the customer could not pay the way they wanted.

What does a secure integration involve?
A payment integration is more than dropping in a checkout button. The sensitive part, the card data, must be handled by the gateway, never stored on your server, so you stay out of PCI scope and your customers stay safe. We use the gateway's hosted or tokenised flows so card details go straight to the provider, and your store only ever sees a secure token.
The other half is reliability. We set up webhooks so that when a payment succeeds, the order is confirmed automatically, even if the customer closes the tab. We handle failed payments, retries, refunds, and partial refunds, and we reconcile edge cases like a payment that succeeds at the bank but times out on return. Then we test every path on real devices before launch.
- Hosted or tokenised flow so card data never hits your server
- Webhooks that auto-confirm paid orders, even on dropped sessions
- Refunds, partial refunds, and failed-payment retry handling
- UPI, netbanking, wallet, and COD options as your market needs
- End-to-end testing across cards, UPI apps, and mobile devices
- UPI
- India's instant bank-to-bank payment system used through apps like GPay, PhonePe, and Paytm. The default way many Indian shoppers pay online.
- Webhook
- An automatic message the gateway sends your store when a payment succeeds or fails, so orders update without the customer having to refresh.
- PCI scope
- The security rules that apply when you handle card data. Using a gateway's hosted flow keeps card data off your server and reduces this burden.
- COD
- Cash on delivery. The customer pays when the order arrives, a major trust driver for first-time Indian buyers.
Payment Gateway Integration — FAQs
Which gateway should I use, Razorpay or Stripe?
It depends on your buyers. For Indian customers, Razorpay or PayU support UPI, netbanking, and wallets natively. For global selling, Stripe and PayPal handle international cards well. Many stores run both so every customer has a familiar option. We recommend the right mix in your quote.
Can you add UPI and cash on delivery together?
Yes. We can offer UPI, cards, netbanking, and wallets for prepaid orders alongside cash on delivery for cautious buyers. Pairing online payment with COD captures both the confident and the first-time shopper, which matters a lot in the Indian market.
Is the integration secure for card payments?
Yes. We use the gateway's hosted or tokenised checkout so card data goes straight to the provider and never touches your server. That keeps you out of heavy PCI scope and keeps your customers' card details safe.
What happens if a payment succeeds but the order does not confirm?
We handle that with webhooks and reconciliation. If a customer pays but the page times out, the gateway notifies your store and the order is confirmed automatically. We also set up failed-payment retries and refund handling for the edge cases.
Can you integrate payments into my app, not just my website?
Yes. We integrate gateways into web stores, custom platforms, and mobile apps. The secure flow and webhook setup work the same way, adapted to your tech stack. Tell us your platform in the quote request and we will confirm the approach.
