The Land Grab for Kiranas
For years, the primary strategy for Indian payment companies like PhonePe, Paytm, and Google Pay was simple: acquire users and merchants at any cost. The Unified Payments Interface (UPI) provided the perfect vehicle for this land grab. It was fast, interoperable,
and, crucially, free to use for both consumers and merchants. This accelerated digital payment adoption at an unprecedented rate, bringing millions of small businesses into the formal economy. The goal was never to profit from the payment itself. Instead, the focus was on building a massive, engaged network that could be monetized later. The merchant, from the local kirana store owner to a larger retailer, became the cornerstone of this strategy.
The Zero-Fee Conundrum
The engine of UPI's growth was a government mandate of zero Merchant Discount Rate (MDR)—the fee merchants typically pay for processing digital transactions. While this was a masterstroke for driving adoption, it created a significant business challenge for the fintechs facilitating these payments. They were spending heavily on technology, cybersecurity, and sales teams to build and maintain the infrastructure, but earning no direct revenue from the trillions of rupees flowing through their systems. This forced a strategic pivot. If you can't make money on the transaction, you have to make money around it. The merchant network became the key to unlocking these new revenue streams.
Data: The New Oil
The most valuable asset generated by a vast merchant network is data. Every transaction provides a detailed look into a business's cash flow, peak hours, customer frequency, and average ticket size. For fintechs, this information is gold. By analyzing this transaction data, they can build sophisticated credit scoring models for small businesses that have traditionally been underserved by banks due to a lack of formal credit history. This data allows fintechs to accurately assess risk and offer financial products with a much higher degree of confidence, turning a simple payment relationship into a far more lucrative lending opportunity.
The Cross-Selling Goldmine
Once a merchant is using a fintech's QR code and payment terminal, they are part of an ecosystem. This trusted relationship becomes the perfect channel for cross-selling a suite of higher-margin products and services. The most significant of these is lending. Fintechs can offer small-ticket working capital loans, merchant cash advances, and other credit products tailored to the merchant's demonstrated business volume. Beyond lending, companies are bundling services like business management software, inventory solutions, insurance, and even advertising. This transforms the payment app from a simple utility into an indispensable business partner, creating what is known as a 'sticky' relationship that is difficult for competitors to break.
Soundboxes and Ecosystem Lock-In
The widespread deployment of devices like soundboxes—which provide instant audio confirmation of a successful payment—is a physical manifestation of this strategy. While they serve a practical purpose for merchants, they are also powerful tools for brand visibility and ecosystem lock-in. Companies like Paytm and PhonePe have been aggressive in deploying millions of these devices. Each device represents a subscription revenue stream (even if small) and solidifies the merchant's reliance on that specific platform, making them less likely to switch to a competitor. It’s a move from being an app on a phone to having a physical, revenue-generating presence inside the store.
A Shift in the Wind: The Return of MDR
Recently, the landscape has started to shift. Recognizing the need for a sustainable economic model, regulators have approved a modest MDR of 0.4% on UPI merchant transactions above ₹2,000, effective from October 2026. While this doesn't apply to the vast majority of small-ticket payments, it provides a new, direct revenue stream from higher-value transactions. This has further intensified the race for merchant acquisition, as fintechs now have an additional incentive to capture larger merchants who will generate this new fee-based income. This move is seen as critical for funding future innovation, infrastructure, and cybersecurity in the payments ecosystem.
