Every time you pay online in India – the UPI collect request, the card form, the net-banking redirect – an invisible company processes the transaction between the merchant and your bank. These are payment aggregators: Razorpay, Cashfree, PayU, CCAvenue and dozens of others, licensed by the RBI to handle the plumbing of digital commerce. They move trillions of rupees annually, yet most consumers have never heard of them. Here is how they work, how they earn, and why the RBI now licenses them like quasi-banks.

What aggregators actually do

A payment aggregator sits between merchants and the banking system. When you click “pay,” the aggregator’s checkout page collects your payment details, routes the transaction to the right processor – the UPI network, a card network, a bank’s net-banking system – handles authentication like OTPs, and confirms success to the merchant in seconds. Behind that simplicity lies complex orchestration: smart routing that retries failed transactions through alternate routes, fraud detection screening each payment, reconciliation matching settlements to orders, and refunds processing. For the merchant, the aggregator collapses dozens of bank integrations into one API and one dashboard; for the customer, it is the familiar payment page. Without aggregators, every online seller would need direct integrations with every bank – an impossible burden that would strangle e-commerce.

How they earn: the MDR and the markup stack

Aggregators earn primarily through the Merchant Discount Rate (MDR) – a percentage of each transaction, typically 1 to 2 per cent for domestic credit cards, lower for debit cards and net-banking, and zero for UPI and RuPay debit cards (where the government mandates zero MDR). From this, the aggregator pays interchange fees to the customer’s bank and network charges, keeping the spread. The spread on a single transaction is thin – often 0.1 to 0.3 per cent – so the business is pure volume: profitability demands billions in monthly payment throughput. Additional revenue comes from value-added services: international payments at higher margins, EMI and BNPL facilitation fees, subscription billing tools, payouts infrastructure for marketplaces paying sellers, and enterprise fraud-management suites. The zero-MDR regime on UPI – which dominates transaction volumes – means aggregators process enormous UPI flows at no revenue, subsidised by earnings from cards and value-added services.

RBI’s licensing regime: why regulation arrived

For years aggregators operated unregulated, holding merchant funds in the gap between collection and settlement – a systemic risk the RBI moved to contain. Since 2020, payment aggregators need RBI authorisation, must meet net-worth requirements (25 crore rupees), undergo annual audits, follow strict customer fund handling rules (money held in escrow, settled within defined timelines), and implement board-approved risk frameworks. The licensing process itself became an industry event: applications were scrutinised, several players operated under in-principle approvals for extended periods, and the final authorisations separated the compliant from the rest. The regime also distinguishes aggregators (who handle funds) from gateways (pure technology providers) – a distinction with major compliance implications. For merchants, the licence is now a due-diligence checkbox: unlicensed aggregators are a red flag.

The platform play: from payments to PaaS

• Payouts: marketplaces, gig platforms and lenders use aggregators to disburse money to sellers, workers and borrowers – the reverse flow of collections.
• Banking-as-a-service: current accounts, virtual accounts and reconciliation tools that embed finance into business software.
• Cross-border: helping Indian merchants sell globally and global merchants sell in India, navigating FEMA and forex regulations.
• Credit: transaction data powers lending – working capital loans to merchants based on their payment flows, a natural adjacency.
• Offline expansion: QR codes, soundboxes and point-of-sale devices extending the aggregator’s reach to kirana stores.

The endgame is payments-as-infrastructure: the aggregator becomes the financial operating system for digital businesses. In an economy moving rapidly toward cashless commerce, that is a powerful position – regulated, competitive, and central to how money moves.

FAQs

What is the difference between a payment aggregator and a gateway?

An aggregator handles funds – collecting from customers and settling to merchants – and needs an RBI licence. A gateway is pure technology routing transactions without touching money.

Why is UPI free but cards charge MDR?

The government mandated zero MDR on UPI and RuPay debit to drive adoption. Card networks operate on commercial interchange models where each party in the chain takes a cut.

Are my card details safe with aggregators?

Licensed aggregators must follow RBI data security norms including tokenisation – they store tokens, not raw card numbers. Check for RBI authorisation before trusting any payment provider.
