AI-Powered Summary
- A payment facilitator (PayFac) helps businesses accept payments by managing relationships with acquiring institutions and sponsored merchants, while handling onboarding, monitoring, and settlement responsibilities based on agreements.
- A payment aggregator collects customer payments, aggregates funds, and settles them to merchants, requiring RBI authorization for non-bank entities in India.
- A payment gateway provides the technical infrastructure for routing payment transactions without handling funds, enabling communication between participants during checkout.
- Businesses should evaluate providers based on their specific needs, such as fund flow, reporting, integration, and responsibilities, rather than treating these roles as interchangeable.
- Key questions to ask providers include details about payment flow, onboarding checks, settlement terms, reporting, and support channels to ensure operational clarity.
- PayU supports Indian businesses with its payment gateway and broader payment solutions, offering integration options tailored to business models and operational needs.
Choosing a payments partner becomes easier when you understand what each provider actually does. A payment facilitator may manage relationships with several merchants. A payment aggregator collects customer payments and settles funds to merchants. A payment gateway provides the technology that routes payment transactions.
These roles can appear together in a commercial offering, which explains why the terms sometimes seem interchangeable. For Indian businesses, however, the distinction matters when reviewing onboarding, fund flows, responsibilities and contracts. Start with the activity being performed, then examine the provider’s legal and commercial role.

What is a PayFac?
A payment facilitator, often shortened to PayFac, helps other businesses accept payments through a relationship with an acquiring institution. The participating businesses are commonly called sponsored merchants or sub-merchants.
In Visa’s payment facilitator model, the facilitator can contract with sponsored merchants on behalf of an acquirer and may receive and distribute settlement proceeds under the applicable arrangement. The acquiring institution remains an important participant in the model.
For a software platform, this can bring payment acceptance closer to the service merchants already use. Imagine a booking platform serving independent studios: the studios may want payment collection, transaction visibility and support within the same operational experience.
That convenience does not remove merchant checks or create automatic eligibility. The actual allocation of onboarding, monitoring, disputes and settlement responsibilities depends on the network rules, jurisdiction and signed agreements. Ask who performs each function instead of assuming the PayFac label answers every question.
What is a Payment Aggregator?
A payment aggregator helps merchants accept customer payments, aggregates the collected funds and subsequently settles them to the merchants.
The RBI’s Payment Aggregator Directions, 2025 distinguish this funds-handling activity from payment gateway technology. The directions cover different categories of aggregation, including online, physical and cross-border activities. Non-bank entities undertaking PA business must seek RBI authorisation under the applicable framework.
For a merchant, the practical implication is that customer payment success and money arriving in the business bank account are separate events. Your agreement and applicable arrangements govern how the funds reach you.
When evaluating an aggregator, review the settlement report as carefully as the checkout demonstration. You should be able to understand which transactions contributed to a payout and how refunds, fees or other adjustments affected it.
What is a Payment Gateway?
A payment gateway supplies the technical infrastructure used to route and facilitate payment processing. Under the RBI definition, the gateway role does not involve handling funds.
At checkout, this technology helps pass the payment request between the relevant participants and communicate the result. The surrounding experience may involve a hosted payment page, a website integration or a mobile software development kit, also called an SDK.
A gateway cannot independently make an issuing bank approve every transaction. A payment can still fail because of customer authentication, account conditions, bank availability or other checks in the payment chain.
Businesses frequently use “payment gateway” as shorthand for a broader bundled service. That is understandable in everyday conversation, but your provider agreement should identify the entities that actually supply technology, collect funds and settle your money.
How the three roles compare
| Dimension | PayFac | Payment aggregator | Payment gateway |
| Main focus | Sponsored merchant payment acceptance | Collecting and settling merchant payments | Routing payment transactions |
| Key relationship | Acquirer and sponsored merchants | Merchants and payment-system participants | Merchant integration and processing infrastructure |
| Funds role | Depends on the model and agreement | Collects funds and settles to merchants | Does not handle funds in the RBI definition |
| Merchant question | Who supports and monitors my account? | Who holds and settles the collected payment? | How does my checkout communicate payment requests? |
| Evaluation priority | Responsibilities and platform fit | Fund flow, reporting and contractual terms | Integration, reliability and payment experience |
PayFac is not a substitute name for an Indian regulatory authorisation. Equally, choosing an aggregator does not mean you can ignore the technology powering checkout. Treat the comparison as a way to understand responsibilities, rather than three mutually exclusive boxes on a purchasing form.
Which setup fits your business?
If you sell your own products online
Begin with a straightforward merchant acceptance requirement. You need customers to pay, orders to receive verified payment updates and finance teams to trace settlements. Evaluate the complete service against those needs.
A hosted checkout may reduce the amount of payment-page development your team manages. A more customised experience can offer design control but also creates implementation and maintenance work. Compare both options using your actual checkout journey.
If you operate software for other businesses
Clarify whether you are simply linking merchants to a provider or taking on a deeper role in payment acceptance. Your desired user experience alone does not determine your regulatory responsibilities.
Map the seller, contracting parties, fund recipient and support owner. Have the proposed structure reviewed before collecting money for other merchants or promising settlement services to them.
If you already have acquiring arrangements
You may be evaluating technology that works with an existing setup. Confirm compatibility, reporting, supported payment modes and responsibility for transaction troubleshooting.
Do not assume changing the checkout interface will automatically change settlement terms. The technology connection and the funds arrangement may be governed separately.
Questions to ask before signing
Request a clear payment-flow diagram showing the customer, relevant providers, banking participants and your business account. Then walk through one successful payment, one failed payment, one refund and one disputed transaction.
Use these questions to make the discussion concrete:
- Which legal entity contracts with my business?
- Which entity collects and settles the funds?
- What onboarding checks apply to my business category?
- Which payment modes are enabled for my account?
- How are fees, taxes and adjustments shown in reports?
- Who investigates a successful payment missing from a payout?
- What support and escalation channels are available?
Ask for a sample report before integration. Check whether your order reference survives through payment, refund and settlement records. If the identifiers cannot be connected easily, your finance team may spend unnecessary time matching payments manually.
Also review the exit process. Understand how remaining refunds, open disputes, historical reports and unsettled amounts are handled if you change providers. This is an operational question worth resolving while everyone is still planning the launch.
How PayU fits into your payment workflow
PayU’s payment gateway offering supports payment acceptance for Indian businesses across supported payment modes. Its broader payments stack and developer documentation provide routes for evaluating checkout and integration needs.
Start the conversation with your business model, sales channels and finance requirements. Ask PayU to confirm the applicable service, contracting entity, payment modes, onboarding requirements and settlement arrangement for your account.
The useful outcome is a payment workflow your team can operate confidently: customers can pay, support can investigate problems, and finance can trace transactions. Availability may vary by merchant category, payment mode and PayU approval.
Frequently asked questions
The terms can overlap in commercial discussions, but they describe different frameworks. PayFac commonly refers to a sponsored merchant model, while India’s PA definition focuses on aggregation and settlement of merchant payments. Review the actual activity and applicable rules.
Under the RBI definition, the payment gateway role provides routing technology without handling funds. A provider selling a broader payment service may also perform aggregation through the relevant legal arrangement.
Yes. A commercial service can combine different capabilities. Your contract should still make responsibilities clear, including payment processing, settlement, merchant support and dispute handling.
Choose by operational fit. Compare setup effort, enabled payment modes, reporting, support and the funds arrangement. A familiar label is less useful than a clear demonstration of how your business will accept and track payments.
