Digital Lending Rails, Part 3: How India’s Paytm is Leveraging Digital Rails for Innovative Lending

India is often cited as a pioneer for digital-financial infrastructure: real-time payments, biometric e-KYC, open-data APIs and more. These rails have enabled not just improved access to finance, but entirely new business models in credit. As regulators and lenders elsewhere explore how to bring innovation into MSME finance and SME lending, the Paytm case offers lessons for how digital rails can power lending products—and how fintechs and digital banks convert infrastructure into scale.

The enabling rails and their influence

India’s ecosystem includes systems such as biometric identity verification (through Aadhaar and e-KYC), payments infrastructure (via the Unified Payments Interface or UPI), merchant acceptance (QR, POS) and continual data flows (bank account, payments, receipts). These rails mean that lenders or fintechs can see richer, timelier data on business cash-flows, digital transactions and merchant behaviour—rather than relying only on historical financial statements.

Because of this, fintechs and digital banks have been able to design lending products that respond to real-time behaviour, transact online, embed repayments, and scale more efficiently. What this means in practice: faster onboarding, digital servicing, and new forms of underwriting that use transaction and cash-flow data.

How Paytm illustrates the model

Paytm, originally known for payments and mobile wallets, has leveraged these rails to expand into lending. On its platform, merchants and consumers can access loans via partner NBFCs or banks through a largely digital journey: “apply in minutes”, onboarding via mobile, minimal documentation.

Beyond speed, Paytm’s edge lies in its ingestion of behavioural and transactional data from its large merchant network: merchant payments, POS volumes, UPI transactions, and settlement flows. With this data, Paytm is well-positioned to estimate revenue potential or merchant health and feed that into underwriting or loan-product design.

Paytm’s payment-gateway and collection capabilities also help manage risk and repayment: their business arm offers solutions for recurring debit, UPI autopay and dynamic QR repayment for lenders/fintechs.

For example, in one development, Paytm entered a “first loss default guarantee” (FLDG) arrangement with a partner lender covering merchant loans—enhancing lender comfort by absorbing initial risk while leveraging merchant behaviour data.

Product innovation enabled by the rails

Using digital-first platforms, fintechs and digital banks in India are innovating in multiple ways:

• On-demand, unsecured lending: Products where merchant or business revenue flows serve as a proxy for creditworthiness rather than heavy collateral or long financial histories.

• Embedded credit: Loans offered at the point of sale, via platforms where merchants already transact, with pre-filled data, minimal friction, and fast disbursement.

• Dynamic repayment linked to revenue: Because digital payments and transaction data are available, lenders can monitor inflows and design repayment schedules that flex with business activity (for example, higher payments in high revenue months).

• Data-driven monitoring & collections: Real-time transaction data enables early-warning triggers, automated repayment reminders, and collection linked to merchant-platform flows rather than separate bank statements.

What innovation teams should note

For DFIs, fintechs and digital banking innovation teams exploring similar opportunities, here are key takeaways from the Indian experience:

1. Data visibility is foundational
   The foundation of these lending innovations lies in frequent, granular transaction or revenue data, enabled by digital rails (payments, merchant flows, UPI). Without that, underwriting remains stuck in legacy, backward-looking models.

2. Platform integration matters
   Lending innovations thrive where fintechs/platforms can integrate into merchant ecosystems, payment gateways and bank accounts. Paytm’s ecosystem shows how payments + merchant network + data = fertile ground for credit innovation.

3. Risk design coupled with collection infrastructure
   The innovation is not only in underwriting but also in the infrastructure for repayments and monitoring. Paytm’s “all-in-one” payments/repayment tech suite allows lenders to automate collection and monitor flows, which reduces risk.

4. Regulatory and governance readiness
   Even in India, innovation has required clear alignment with regulation, data governance and risk frameworks. For DFIs/innovators, replicating the model means building data-consent frameworks, auditability of score models, and clear collections governance.

5. Scalable architecture from pilot to mainstream
   The leap isn’t in the prototype alone—it’s in scaling with repeatable architecture, clear workflows, monitoring dashboards, and product governance. The rails shift the question from “Can we do it?” to “Can we do it at scale while controlling risk?”

Challenges and caveats

While the Indian case is rich, there are important caveats innovation teams must keep front of mind:

• Regulatory oversight: In rapid innovation, regulatory scrutiny follows—digital lending norms, data-protection, consumer-protection and payments-bank scrutiny all require governance.

• Credit-behaviour complexity: While transaction data improves insights, it does not eliminate risk entirely—entrepreneur behaviour, external shocks, and sector-specific risks remain.

• Platform concentration risk: The strongest innovators tend to be large platforms with rich data flows. For smaller players, acquiring scale and data access may be harder.

• Repayment alignment: Models that flex with revenue must still ensure lender viability: fixed costs, margins and portfolio discipline matter.

Conclusion

India’s digital-financial rails have enabled fintechs and digital banks to launch lending products that were impossible a decade ago: unsecured, embedded, dynamic, data-driven. For innovation teams in DFIs, fintechs and digital banks working in markets with evolving infrastructure, the lesson is clear: it isn’t simply “build the infrastructure and wait” — the opportunity lies in using the rails now to design new credit models.

At Factfin, we help institutions design technology, governance and data workflows to ensure these innovations move from pilots to scalable platforms—products that flex with business growth, while managing risk and governance from day one. The next frontier of lending isn’t just digital—it’s adaptive, integrated and built on a foundation that enables high-growth companies to access credit when they need it most.
