linq: white-label PayFac-as-a-Service for software platforms

PayFac-as-a-Service lets a software company offer payments inside its product without becoming a registered payment facilitator itself. Your customers are onboarded as sub-merchants under a provider's registration, underwriting, risk and settlement infrastructure, and your platform earns revenue from the payments it enables. linq is the white-label PayFac-as-a-Service from Merchant Focus, built for SaaS companies and ISVs that want payments to feel like a native part of their product.

What is PayFac-as-a-Service?

A payment facilitator, or PayFac, signs up merchants to accept card payments and handles the funds flow on their behalf. It sits between your customers and the card networks, and it takes on responsibility for underwriting, monitoring and compliance.

Becoming a registered PayFac gives a software company a great deal of control, but it also means taking on all of that responsibility. PayFac-as-a-Service gives you the benefits of the model without the build. You integrate with a provider that already operates the infrastructure, and you offer payments to your customers under your own brand.

How linq works

Your customers sign up inside your product. linq supports a branded onboarding flow, so your customers never leave your platform to get set up.

We handle underwriting and approval. Each business is reviewed, verified and approved by our team, with ongoing monitoring after approval.

Payments run through your platform. Your customers accept cards and bank payments in the checkout, billing or point-of-sale experience you design.

Funds settle and you earn. Your customers get paid, and your platform earns revenue from the processing it enables.
