ISB study warns small merchants may cut UPI acceptance if MDR is introduced

A recent study conducted by the Indian School of Business highlights that a significant portion of small vendors would likely cut back on accepting Unified Payments Interface (UPI) transactions if a Merchant Discount Rate (MDR) is implemented. The findings point to growing apprehension among micro-merchants regarding the financial viability of accepting digital payments without fee exemptions. Currently, the zero-MDR regime encourages widespread adoption among small-ticket retailers, but the introduction of charges could prompt merchants to favor cash transactions to protect their daily earnings.

Historically, the absence of MDR has driven massive transaction volumes across India's digital public infrastructure, benefiting both consumers and small businesses through instantaneous settlement. However, payment service providers and banks argue that processing costs require sustainable revenue streams, creating a policy tug-of-war between expanding financial inclusion and commercial viability. If MDR is eventually levied, small merchants face a direct squeeze on their margins, contrasting with the prior zero-cost operating model that accelerated digital retail adoption.

Tax professionals and financial advisors must prepare retail clients for potential cost adjustments if transaction fee policies change. Businesses should closely monitor regulatory announcements from the central bank and National Payments Corporation of India regarding digital payment pricing structures. Bottom line: advisors need to factor potential merchant processing fees into client budgeting models to safeguard retail profit margins against upcoming policy shifts.
