PayFac-as-a-service

Definition

PayFac-as-a-service (PFaaS) is a commercial model where a vertical software company embeds card and related acceptance, usually sets the merchant sell price, and keeps the merchant relationship, while a separate registered payment facilitator underwrites those businesses, holds the acquiring program with a sponsoring acquirer, and stays on the merchant processing terms. The software company takes a rate on volume. It is not the registered PayFac on day one.

This page is the rented-facilitator model. Adjacent terms are Vertical Fintech’s. They are not this page. The PayFac itself (who is registered), application fees, destination charges, residuals, and sponsor-bank details sit next to this definition. Some vendors also sell a later path to take the license on the same stack. That path is a product choice, not the definition of PFaaS.

Why it matters

This is the beachhead job on the payments table: take a rate without becoming a PayFac. If you run vertical software, PFaaS is how you put checkout and merchant onboarding inside the product, mark up a buy rate or take an application fee, and stay the software brand your merchants already trust. You do not stand up card-network registration, an underwriting desk, or sub-merchant loss reserves on day one. The honest trade is control. Someone else is the registered party, someone else underwrites, and someone else can change the buy rate or the program rules. Ask who is registered, whether you can set sell price, whether there is a documented path to take the license later, and what happens to merchant terms if you leave. If marketing calls you a PayFac and the contract says they hold registration, you bought PFaaS. Name it that way.

  • Payments: PayFac-as-a-service and platform payments. Take a rate on merchant volume without becoming a PayFac.
  • Payment facilitator: The registered model this service rents. Read that first if the question is who is actually the PayFac.
  • Rainforest: PFaaS for US vertical SaaS that will set merchant price and stay the software, not a path to become the PayFac.
  • Finix: PFaaS now, same API if you later take the license.
  • Infinicept: White-labeled embedded payments with Launchpay holding PayFac registration and a same-stack path to registered PayFac later.

FAQ

If I use PayFac-as-a-service, am I a PayFac?

No. You are the software company taking a rate. The vendor (or its named facilitator) is the registered party that underwrites and stays on the processing terms. If you later take the license on the same stack, that is a separate program change, not what you bought on day one.

Do I own the residual economics?

You own whatever spread or fee the contract gives you, usually sell price minus a buy rate, or an application fee. You do not own the acquiring license or the underwriting book unless the agreement says you graduate to registered PayFac. Confirm the buy rate, who can change it, and whether merchant terms stay with you if you leave.
