Payment Facilitator (PayFac)

A payment facilitator, commonly shortened to PayFac, is a company that holds a single master merchant account with an acquirer and signs up many smaller businesses, known as sub-merchants, to accept card payments under that account. Instead of each business going through a full acquiring application, the sub-merchants contract with the facilitator, which onboards them, carries out underwriting, routes their transactions and pays out their sales proceeds.

The model, formally recognized by the major card schemes in the early 2010s, made it possible for a small seller to start accepting cards within minutes. Well-known platforms that operate as facilitators include online checkout providers and point-of-sale companies serving small merchants, and many software platforms now embed payments for their own users this way as part of embedded finance.

The facilitator is registered with the card networks through a sponsoring acquirer, which remains the network member responsible for the facilitator's activity. In a typical flow:

1. A business signs up online with the facilitator and provides identity and business details for KYB checks.
2. The facilitator screens and underwrites the sub-merchant under policies agreed with the acquirer, assigns a merchant category code and boards it on its platform.
3. Card transactions from the sub-merchant are authorized and cleared through the acquirer under the facilitator's master account, with sub-merchant identifiers in the transaction data.
4. The acquirer settles the combined proceeds to the facilitator, which deducts its fees and pays each sub-merchant its share.

The facilitator usually sets the sub-merchant's pricing, often a simple blended rate, and earns the margin between that price and the merchant discount rate and other costs it pays the acquirer.

A facilitator takes on functions that would otherwise sit with the acquirer, and with them the liability:

• Underwriting and onboarding, including screening against prohibited business types and identifying high-risk merchants.
• Transaction monitoring for fraud and laundering, including transaction laundering, where an unapproved business pushes sales through an approved sub-merchant.
• Chargeback liability: if a sub-merchant cannot cover a chargeback or refund, the facilitator must, and the acquirer is liable behind it.
• Funds handling: settlement funds pass through the facilitator, so it must manage reserves, delayed payouts and the security of sub-merchant money.
• Compliance with card network rules and data security standards.

Card networks set annual volume thresholds above which a sub-merchant is expected to sign a direct agreement with the acquirer, so the model is aimed at small and mid-sized sellers.

An independent sales organization (ISO) refers merchants to an acquirer, but each merchant receives its own merchant account and the acquirer underwrites and funds it. A facilitator, by contrast, aggregates merchants under its own account and controls the money. A merchant of record goes further still: it sells to the end customer in its own name, so the business behind it is not a merchant in the card system at all. The PayFac model is sometimes loosely described as payment aggregation.

Card network registration is not a government license. Whether a facilitator also needs one depends on how money flows. In the United States, holding and paying out sub-merchant funds can raise money transmission questions; many facilitators rely on the agent of the payee exemption, on states that exclude payment processors, or on settlement through a sponsor bank using an FBO account. In the European Union and the United Kingdom, a facilitator that holds merchant funds generally needs authorization as a payment institution, because merchant acquiring is a regulated payment service. Some platforms that do not want the burden of becoming a full PayFac use a provider's managed or white-label facilitator program instead.
