Introduction

Accepting digital payments has become essential for businesses of every size. Whether you run an online store, SaaS platform, marketplace, or subscription business, customers expect fast and secure payment options. Behind every successful transaction is a payment infrastructure that makes the process seamless.

One important part of this ecosystem is the Payment Facilitator, commonly known as a PayFac. The PayFac model has transformed how businesses accept payments by making merchant onboarding quicker and reducing the complexity of payment processing.

What Is a Payment Facilitator (Payment Aggregator in India)?

A Payment Facilitator (PayFac) is a payment service provider that enables businesses to accept electronic payments without requiring each business to establish its own direct merchant account with a bank.

Instead, the PayFac maintains a master merchant account and allows individual businesses, often called sub-merchants, to operate under it. This significantly speeds up the onboarding process while simplifying payment acceptance.

The PayFac is responsible for onboarding merchants, verifying their identity, monitoring transactions, managing compliance, and settling funds securely.

How Payment Aggregators Work: The Sub-Merchant Model

A Payment Facilitator acts as the intermediary between merchants, acquiring banks, payment networks, and customers.

The process typically follows these steps:

1. A business signs up with the Payment Facilitator.
2. The PayFac verifies the merchant's identity through Know Your Customer (KYC) checks and risk assessments.
3. Once approved, the merchant becomes a sub-merchant under the PayFac's master account.
4. Customers make payments using cards, UPI, digital wallets, or other supported methods.
5. The payment is authorised through the acquiring bank and card network.
6. After settlement, the PayFac transfers the funds to the merchant after deducting applicable fees.

Because the PayFac manages compliance and operational processes, businesses can begin accepting payments much faster than through traditional merchant account setups.

Benefits of Using a Payment Facilitator

Using a Payment Facilitator (PayFac) simplifies payment acceptance by allowing your business to act as a master merchant, letting sub-merchants process transactions under your umbrella. This eliminates the need for lengthy direct bank underwriting, reducing onboarding times and operational complexity.

Benefits:

• Rapid Onboarding: Bypasses the tedious paperwork and complicated approvals of traditional merchant accounts, allowing new sellers to start taking payments in minutes.
• Monetisation & Revenue: Platforms can take a percentage of processing fees, creating a lucrative new revenue stream without building processing infrastructure from scratch.
• Reduced Compliance & Risk: The PayFac handles the heavy lifting of payment industry compliance (like PCI-DSS), underwriting, and chargeback management.
• White-Labeling: You can embed payments directly into your software and maintain your brand identity.
• Simplified Payouts: Effortlessly routes funds to multiple sub-merchants, suppliers, or contractors globally.

Payment Aggregator vs Payment Gateway: Key Differences

Types of Payment Aggregators in India

Payment aggregators in India can be broadly classified into two types based on the mode of payment they support:

1. Online Payment Aggregators: Online payment aggregators enable businesses to accept digital payments through websites and mobile applications. They support multiple payment methods, including credit cards, debit cards, UPI, net banking, and digital wallets. These platforms simplify merchant onboarding and securely process online transactions.
2. Offline Payment Aggregators: Offline payment aggregators facilitate in-person digital payments through Point of Sale (POS) terminals, QR codes, and mobile payment devices. They are commonly used by retail stores, restaurants, supermarkets, and other physical businesses to accept cashless payments.

Examples of RBI-Approved Payment Aggregators

The following are some well-known payment aggregators that have received authorisation from the Reserve Bank of India (RBI) to operate as online Payment Aggregators:

• PhonePe Payment Gateway
• Razorpay
• Cashfree Payments
• PayU
• CCAvenue
• Pine Labs Online
• BillDesk
• Paytm Payment Gateway
• Easebuzz
• Amazon Pay (India)

Note: The RBI periodically updates the list of authorised Payment Aggregators. Businesses should verify a provider's authorisation status on the RBI website before choosing a payment partner.

How Payment Aggregators Make Money

Payment aggregators make money by acting as the digital middleman between customers and merchants. They primarily earn revenue through per-transaction processing fees, setup/subscription charges, and premium value-added services like instant settlements, fraud detection, and multi-currency processing.

The main revenue streams are broken down below:

1. Transaction Fees (The Primary Driver)

• Merchant Discount Rate (MDR): The most common way aggregators earn is by charging a small percentage (usually between 0.5% to 2.5%) of the total transaction amount every time a customer makes a purchase.
• Flat Fees: For some specific transaction types or lower-ticket items, they might charge a flat fee (e.g., $0.30 plus a percentage).

2. Setup and Maintenance Fees

• Onboarding/Setup Fees: A one-time fee charged to merchants to integrate the aggregator's API into their website or app.
• Subscription/Platform Fees: Recurring monthly or annual fees that businesses pay to access dashboards, invoicing tools, and reporting analytics.

3. Value-Added Services

• Instant Settlements: Merchants typically have to wait a couple of days (e.g., T+2) for funds to clear. Aggregators charge a premium fee to disburse funds instantly on the same day.
• Fraud Management: Advanced tools to block suspicious transactions or protect merchants from chargeback liabilities often come at an additional cost.
• Currency Conversion: For cross-border transactions, aggregators charge markups or specific fees to convert foreign currencies.

4. Interest on Pooled Funds

• Customer payments are routed through a shared, regulatory-compliant escrow or nodal account before settling with the merchant. Because large transaction volumes sit in these accounts for short periods, aggregators can earn interest on the pooled float.

Making the Right Choice for Your Business

Payment Aggregators simplify digital payment acceptance for growth-stage businesses. The sub-merchant model enables fast onboarding, unified payment infrastructure, and consolidated settlements critical for D2C brands, marketplaces, and SaaS platforms prioritising speed-to-market.

Verify RBI authorisation before partnering. Licensed PAs offer regulatory compliance, financial stability, and operational continuity. As payment volumes scale beyond ₹10 crore monthly, evaluate direct merchant accounts or hybrid models for optimised costs and settlement control.
