A payment facilitator, or PayFac, is a payment service model where a company enables other businesses to accept payments as sub-merchants under its broader acquiring setup. Instead of each merchant opening a separate merchant account directly with an acquiring bank, the PayFac manages onboarding, payment acceptance, risk monitoring, and parts of the merchant lifecycle.
Payment facilitators make it easier for merchants to obtain merchant accounts, which are required to accept online customer transactions. By underwriting a business as a sub-merchant, Payfacs eliminates the need for the merchant to go through a long and troublesome process of applying, verifying and onboarding at the acquiring bank. The PayFac model is especially useful for platforms, marketplaces, SaaS companies, and payment businesses that need to onboard many merchants quickly and manage payment acceptance at scale.
In the PayFac model, the payment facilitator works with an acquiring bank or payment processor to bring multiple merchants into a single managed payment setup. These merchants are usually registered as sub-merchants, while the PayFac manages much of the onboarding and payment operations process.
A typical PayFac model includes:
For merchants, this model reduces the time and complexity of starting to accept payments. For platforms and payment businesses, it provides a way to offer embedded payments or merchant services without sending every merchant through a separate acquiring-bank onboarding process.
The PayFac model is often used by platforms, marketplaces, SaaS companies, vertical software providers, and payment businesses that want to offer payment acceptance to their own merchants or users.
For example, a marketplace may use a PayFac model to onboard sellers and let them accept payments through the platform. A SaaS company may use it to add embedded payments for its customers. A PSP may use the model to serve multiple merchants under a managed payment setup.
The work of payment facilitators is not limited to underwriting merchants. They also provide e-commerce businesses with the infrastructure they need to accept and process all kinds of transactions. Besides, payfacs offer many value-added services, including:
Compared with traditional direct acquiring, PayFacs often provide a more streamlined onboarding experience and more merchant-facing tools. This can help businesses accept payments faster, enter new markets, and manage payments with less operational complexity.
To start accepting payments through a PayFac, a merchant usually submits business information, passes verification, and is onboarded as a sub-merchant. Once approved, the merchant can begin accepting payments without setting up a direct merchant account with an acquiring bank.
For companies building or managing a PayFac model, payment infrastructure matters. A PayFac needs tools for merchant management, provider connectivity, transaction routing, monitoring, reconciliation, chargebacks, and reporting. Corefy supports this infrastructure layer by helping payment businesses connect providers, manage payment flows, and operate multi-merchant payment setups more efficiently.
