Looking for recommendations on payment gateway for my business, we will have good transaction volumes (₹2-3 crore/month). Wanted to know what is the best possible MDR rates I can get. So far, I have explored Razorpay, Cashfree, and PhonePe, but they have offered only marginal reductions in MDR. I am open to other suggestions or contacts that can help negotiate better rates. And even a benchmark MDR rate I can use for negotiating. Thanks.
