Why Most SaaS Founders Overpay on Gateway Fees

Most payment gateways in India charge between 1.4% and 2% per transaction, plus 18% GST on those fees. On a monthly volume of ₹10 Lakhs, that's over ₹21,000 in gateway costs — money that could go toward product development or marketing.

What to Look For in a UPI Payment Gateway

  • ✓Zero or low transaction fees — Preferably a flat monthly fee rather than a percentage
  • ✓Instant settlement (T+0) — Funds should reach your bank account immediately, not after 2-7 days
  • ✓Automated verification — No manual reconciliation of payment emails
  • ✓Developer-friendly API — Clean REST endpoints, typed SDKs, clear documentation
  • ✓No escrow or holds — Your money should go directly to your bank, not sit in an intermediary account

The Verdict

For SaaS founders, indie hackers, and developer-led businesses processing ₹5 Lakhs+ per month, MyMobPay is the clear winner. Zero transaction fees, instant bank settlement, and a developer-first API that takes minutes to integrate. If you need multi-currency or international cards, Razorpay or Cashfree may still have a role — but for pure UPI collection in India, nothing beats the direct rail.
