From my point of view PayU is suited for large business only. But small business can also use PayU to collect payments from their customers but again, I think PayU is suited for large business mainly.
Payu is a much better and easier to use platform. It doesn't charge any upfront fee or annual fee. The payment processing charge is very low. The remittance is very quick and there is no minimum amount criteria for payment remittance. Payu offers tons of payment options. The best part is the payment page. The page is simple and beautiful
Easy to set up, and integration happens with simple steps. Various payment options. Easy to export reports. Instant payment notification and updates on dashboard. Useful for individuals, SMEs, and companies. Adding creative features from time to time for more improvement. The support team is responsive among other tools like Paytm, Google Pay, and Stripe. Amazon Pay is best when it comes to charges, but it has missing payment methods of Paylater apps, EMI apps. If it reduces its flat 2% charge, then it will trend at top.
