What is the difference between Razorpay and PayU?
Both are Indian payment gateways handling cards, UPI, net banking and wallets, charging a percentage per transaction with settlement to your bank account on a defined cycle. Razorpay is generally regarded as the more developer-friendly of the two, with stronger documentation and dashboard tooling. PayU is longer established and often competitive on rates at higher volumes. The functional overlap is large; the differences are in integration quality, support and edge-case handling.
Gateway comparisons online are dominated by rate tables that go out of date within months, because published rates are starting points and anything above modest volume is negotiated. Treat any specific percentage you read, including anywhere here, as indicative and confirm current terms directly.
What does not change month to month is the thing that actually costs you money: transaction success rate. A gateway that fails two per cent more transactions on your traffic mix costs you far more than a rate difference, and it is invisible unless you look for it. Test both on real traffic before committing if the volume justifies it.
