What is a Payment Facilitator (PayFac)?

A payment facilitator (PayFac) is a specialised merchant services provider and merchant services business that enables businesses - referred to as sub-merchants - to accept payments (including card payments and other electronic payments) under the PayFac's master merchant account, removing the need for each merchant to establish a direct acquiring relationship or maintain an individual merchant account.

In simple terms, a PayFac sets up and manages payment processing services on behalf of businesses, allowing them to start accepting online payments quickly and efficiently.

Payments are a vital part of any online business, yet the underlying processes can often seem complex and confusing.

This article unpacks the payment facilitator model from the ground up, explaining how it works, why it emerged, the responsibilities involved, and how it compares to other payment solutions - all in clear, straightforward language to help you understand this important piece of the payments ecosystem.

How the Traditional Model Worked

Traditionally, a merchant wanting to accept electronic payments online would apply for a traditional merchant account with an acquiring bank or merchant account provider.

That process involved an extensive underwriting process, Know Your Customer (KYC) checks, contract negotiations, and a technical integration between the merchant, a payment gateway, and a payment processor. Each merchant received their own merchant ID (MID) and merchant bank account.

While this model offers greater control and often lower payment processing fees for larger businesses with high transaction volumes, it can be slow, complex, and resource-heavy - particularly for SaaS platforms, online marketplaces, and SMBs.

In many cases, onboarding can take days or even weeks due to compliance checks and direct relationships required with acquiring banks.

Why PayFacs Emerged

Platforms and marketplaces needed a way to onboard many sellers quickly and let them accept payments - including online card payments, local payment methods, and other payment options - without each seller applying for their own merchant account.

The payment facilitator (PayFac) emerged as a business model to solve that friction.

By aggregating sub-merchants under a master account, PayFacs dramatically speed up merchant onboarding, enables embedded financial services into platforms, and allows businesses to monetise payment processing by turning customer payments into a revenue stream.

This streamlined onboarding process can allow businesses to start processing payments within hours for low-risk merchants, rather than days or weeks, with full verification often completed progressively.

How a PayFac Works

A payment facilitator registers with an acquiring bank and, via a sponsoring acquirer, with card networks, and secures a master merchant account (master MID). They can then integrate payment gateways and payment processors.

Sub-merchants are typically assigned unique identifiers within the PayFac’s system, even though they operate under the master merchant account.”

PayFacs must also register with major card networks like Visa and Mastercard, adhering to strict card network rules and compliance requirements.

Typical Flow

If a sub-merchant exceeds certain transaction or risk thresholds, they may be required (depending on the card network and acquiring bank) to move to their own merchant account and establish a direct relationship with an acquiring bank.

PayFac vs Payment Gateway vs ISO: What's the Difference?

With these terms often used interchangeably, they represent very different roles within the payment processing ecosystem - from technical infrastructure to full-service payment facilitation.

What Responsibilities Does a PayFac Take On?

Operating under the PayFac model means accepting substantial responsibilities:

Why Businesses Choose to Become PayFacs

There are several incentives:

However, despite all the benefits, a larger business with higher transaction volumes may prefer a traditional merchant account for lower per-transaction costs and greater customisation.

The PayFac-as-a-Service Model

Not every business model wants to take on the complexity of full PayFac registration, licensing, and compliance.

PayFac-as-a-Service (PFaaS) providers allow businesses to provide payment services without becoming a fully registered payment facilitator.

These providers offer access to payment facilitation, including acquiring relationships, onboarding tools, risk management, and compliance infrastructure - typically via APIs.

This approach reduces technical setup, accelerates time-to-market, and allows businesses to embed payments without managing the full operational and regulatory burden.

FAQs

How is a PayFac Different From a Traditional Merchant Acquirer?

A traditional acquirer provides individual merchant accounts and direct acquiring relationships, requiring each business to undergo a full onboarding process. A payment facilitator instead aggregates sub-merchants under a single master merchant account, simplifying onboarding and managing payments on their behalf.

What is a Sub-Merchant?

A sub‑merchant is a business operating under a PayFac's master account. They can accept payments and process transactions without maintaining their own independent merchant ID or direct acquiring relationship.

What are the Risks of the PayFac Model?

Risks include liability for fraud, chargebacks, and compliance breaches across all sub-merchants. Because PayFacs aggregate payments, they must maintain robust fraud prevention, AML controls, and transaction monitoring systems to mitigate financial and regulatory risk.

How Long Does it Take to Become a Registered PayFac?

Timelines vary. Becoming a fully registered payment facilitator can take several months due to PayFac registration, compliance checks, and approvals from acquiring banks and card networks. By contrast, using a PayFac-as-a-Service model can reduce onboarding time to weeks.

What Does a PayFac Need in Terms of Compliance & Licensing?

Core requirements include PCI DSS compliance, KYC, anti-money laundering controls, and adherence to card network rules. Depending on the region, PayFacs may also require separate licenses, such as authorisation as a Payment Institution (PI) or Electronic Money Institution (EMI), or operating under a licensed partner.

What is the Difference Between a PayFac & a Marketplace?

A marketplace connects buyers and sellers, while a payment facilitator enables payment processing. Many online marketplaces adopt the PayFac model to manage payments internally, but not all marketplaces operate as PayFacs.
