India moves to give its instant payments network a business model
↗
India’s new legislation enables future merchant fees on its UPI instant-payments network, ending a four-year zero-fee regime for businesses.
Engineers building or integrating payment systems in India must now design for potential merchant fees on UPI transactions. The change creates a new cost layer for businesses while preserving free consumer payments, altering the economic model of India’s dominant digital-payments platform.

The legislation does not impose fees immediately but removes the legal barrier to charging merchants for UPI transactions.
High-value transactions, though few in number, represent most of the network’s payment volume and are the likely target for any future fees.
Payment apps and banks stand to gain new revenue, but the exact distribution of fees among ecosystem participants remains unspecified.
THE READ
What elseif makes of it.
India’s UPI network has operated without merchant fees since 2020, a policy intended to drive adoption. The new legislation does not introduce fees but creates the legal framework for them, shifting the network toward a revenue-generating model. For engineers, this means payment integrations must now account for potential transaction costs that could apply to certain merchant categories or transaction sizes. The change does not affect peer-to-peer payments, so consumer-facing apps remain free to use.
The cost of adopting this change is primarily architectural. Payment service providers and merchants will need to update systems to handle fee calculations, reporting, and reconciliation. Smaller merchants may be exempt, but larger businesses processing high-value transactions will likely face fees, requiring new logic to route or optimize payments. The legislation leaves fee structures undefined, so engineers must design flexible systems that can adapt to future rules without requiring full redeployment.
The new model stops working if fees are set too high or applied too broadly, risking merchant pushback or reduced transaction volumes. The material suggests fees may target only high-value transactions, preserving UPI’s accessibility for everyday use. However, if fees are extended to all merchant transactions, the network’s competitive edge against card payments or cash could erode. Engineers should monitor regulatory updates to adjust integrations before enforcement begins.
The legislation reflects a broader debate over who funds UPI’s growth, government, banks, or merchants. Payment companies and banks have argued that zero fees are unsustainable as transaction volumes rise, while the government has prioritized adoption. The compromise appears to be a tiered fee structure, allowing the network to scale while generating revenue. For engineers, this means designing systems that can support both fee-free and fee-bearing transactions, depending on merchant size or transaction value.
