Payment Gateway Integration Without the Checkout Headaches

Most Indian businesses ask for Razorpay first -- it's the fastest to approve and has the most predictable settlement times for a new merchant account. Stripe comes up mainly for businesses billing international clients in USD/EUR, and PayU or CCAvenue still get requested by businesses that already have a merchant account with them from before Razorpay's rise.

The part that actually takes the time isn't the checkout button -- it's handling what happens after: webhook verification so a payment status can't be spoofed, refund handling, and making sure a failed or abandoned payment doesn't silently lose the order. Pricing depends on whether it's a single gateway on an existing site (lower end) or multiple gateways plus UPI and subscription billing (higher end).

Frequently Asked Questions

Razorpay for Indian rupee payments and faster settlement to an Indian bank account; Stripe mainly if you're billing international clients in USD or EUR. Both can be added if you need each.

The gateway account itself is created and verified by you (KYC is tied to your business), but the integration, webhook setup and testing are handled end to end.

Most projects range INR 5,000-60,000 depending on how many gateways, UPI, subscriptions and refund automation are involved.
