How regional UPI activity, QR acceptance and everyday transactions shape payment operations across India.

India’s digital payment story extends well beyond its largest metropolitan cities. From organised retail in Mumbai and Bengaluru to neighbourhood businesses in smaller towns, UPI and QR-based acceptance are part of everyday commerce. But a common payment network does not mean every merchant operates in the same way.

A grocery store handling frequent smaller transactions has different operational requirements from a restaurant managing peak-hour collections or an online retailer serving customers across states. NPCI’s regional and merchant-category statistics help explain the scale and composition of UPI activity—and why businesses must think beyond acceptance to transaction visibility and reconciliation.

Key takeaways

• Maharashtra recorded 1.99 billion UPI transactions in August 2025; Karnataka and Uttar Pradesh each exceeded one billion.

• State-wise UPI figures cover total activity, not merchant payments alone, and do not establish growth rates.

• PwC reports that roughly 75% of new QR deployments were in Tier 2 and Tier 3 cities; the exact period and definition should be checked against the original handbook before publication.

• Groceries, restaurants, telecommunications and fuel are major merchant transaction categories.

• As merchants scale across regions, payment-status visibility, exception handling and reconciliation become important.

1. Where is India’s UPI activity concentrated?

NPCI’s August 2025 state-wise UPI statistics show a significant difference in the absolute volume of transactions across states. Maharashtra led with 1,985.58 million transactions (9.92% of reported volume), followed by Karnataka and Uttar Pradesh.

Maharashtra recorded nearly 1.99 billion UPI transactions, while Karnataka and Uttar Pradesh each exceeded one billion. This illustrates differences in the scale of recorded activity; it does not establish which states are growing fastest or how much of each state’s activity is merchant-related. Comparable time periods and merchant-specific measures would be needed for those conclusions.

2. Three large markets, different business contexts

Maharashtra: commercial scale

Maharashtra recorded approximately ₹2.33 lakh crore in UPI transaction value in August 2025. Large retailers, restaurants and neighbourhood shops may accept payments through different interfaces, but each needs dependable transaction confirmation and records.

Karnataka: integrating payments with operations

Karnataka recorded approximately 1.08 billion transactions worth ₹1.42 lakh crore. For example, a Bengaluru restaurant using a point-of-sale system must connect payment outcomes to orders and later reconcile transaction records. This is an illustrative operational example, not a conclusion about all Karnataka merchants.

Uttar Pradesh: breadth of consumer markets

Uttar Pradesh recorded approximately 1.06 billion transactions. Its major cities and smaller towns illustrate the potential for a common payment method across diverse business environments. Merchants expanding across locations still need consistent processes for identifying and reviewing payments.

3. Beyond metros: the role of QR acceptance

QR codes can provide a relatively low-cost way for smaller merchants to accept supported digital payments without conventional card terminals. PwC’s Indian Payments Handbook 2025–2030 describes the expansion of QR acceptance beyond metros and reports that approximately 75% of new QR deployments occurred in Tier 2 and Tier 3 cities. The exact methodology and reporting period should accompany this figure in the final citation.

A grocery store, pharmacy or local service provider can display a QR code and use supported payment notifications to review collections. However, deployment measures acceptance infrastructure—not necessarily transaction usage or equal adoption in every district.

4. Everyday purchases are a major part of merchant UPI activity

Merchant-category statistics offer a complementary view of UPI: what kinds of businesses receive transactions. The following figures are taken from the article’s NPCI August 2025 merchant-category dataset and should be cross-checked against the original category table before publication.

Everyday purchases generate substantial transaction counts. Merchant categories also differ in how payments need to be managed: restaurants may face peaks during meal periods, grocers may handle many smaller payments, and online retailers may need to match payments with orders across locations. These are illustrative operating patterns, not patterns directly measured in the table.

5. Different merchants, different operational needs

Accepting a payment is only one step. Businesses may also need to confirm its final status, match it to an order or invoice, investigate exceptions and compare records with settlement information from the relevant licensed providers. Manual checks may become difficult as volumes grow.

6. India’s national UPI scale

NPCI reported 24.51 billion UPI transactions, worth approximately ₹29.82 lakh crore, and 752 banks live on UPI in August 2026. These are national figures from a later period than the August 2025 regional comparisons and should not be treated as a direct year-on-year comparison with individual states.

7. What should businesses monitor?

Businesses should verify which data fields and workflows their chosen providers support. Not every payment integration offers the same reporting or reconciliation capabilities.

8. From regional activity to connected collections

India’s payment network can serve businesses across very different markets, but payment acceptance alone does not solve every operational problem. API-first collection infrastructure can help businesses connect supported payment initiation and transaction-status workflows with their internal systems and maintain records for reconciliation.

How Paywize fits into the ecosystem

Paywize is an API-first Technology Service Provider enabling businesses to integrate supported collection workflows through licensed payment partners. Paywize Collections can support payment initiation, transaction-status visibility and reconciliation-related workflows within the scope of available integrations.

Conclusion: one network, different business needs

India’s UPI activity is geographically widespread, while merchant payment operations remain varied. NPCI data illustrates the scale of state-wise transactions and everyday merchant categories; QR adoption research shows acceptance infrastructure expanding beyond metros. For businesses, the opportunity is not only to accept digital payments but to maintain dependable visibility, records and reconciliation as they grow.

Frequently asked questions

Which state recorded the highest UPI volume in August 2025?

Maharashtra, with 1,985.58 million transactions according to NPCI.

Does state-wise UPI data represent merchant payments only?

No. It includes transactions across different UPI purposes.

Does the chart show which state is growing fastest?

No. It compares one month’s transaction volumes; growth requires comparable periods.

Are QR payments expanding beyond major cities?

PwC reports substantial QR deployment in Tier 2 and Tier 3 cities; deployment should not be confused with actual usage.

What should merchants assess in payment infrastructure?

Supported payment methods, integration capability, transaction status, exception handling, settlement information, and reconciliation.
