Payfac as a service means a registered payment facilitator carries the infrastructure, the sponsor bank relationships, card network registration, PCI compliance, underwriting, and risk, while your software company gets the economics of the model: you onboard merchants under your brand, set the rates they pay, and keep the spread. Some providers call it managed payfac. Either way, the point is the same: payfac economics without the seven-figure build.

If you're not sure what a payfac is in the first place, start with our guide to what a payfac is and how payment facilitation works, then come back.

The build vs buy math

Becoming a registered payment facilitator is commonly estimated at seven figures in cost and 12 to 18 months of work before the first transaction: sponsor bank agreements, network registration, PCI DSS Level 1, an underwriting and compliance team, and capital reserves. And registration is the entry fee, not the finish line, since risk and compliance are permanent operating costs.

Payfac as a service inverts that. The provider already made those investments, so your first merchant can be approved and billing in days instead of years, and your cost structure is a per-transaction buy rate instead of a payroll of compliance staff. The trade is a slice of the margin, which for every software company outside the top processing tier is a trade worth making.

What payfac-as-a-service companies do

The payfac-as-a-service category is built around developer platforms: companies like Finix, Rainforest, Payrix, and Tilled expose payments infrastructure through APIs and take on the registration and compliance burden, so software platforms can embed payments and monetize them. They're built for companies with engineering teams that will integrate, certify, and maintain a payments stack inside their own product.

That's the gap most founders fall into: you want the economics, but you don't want to build and maintain a payments integration, and payments alone doesn't get you a sellable product. You still need the software your merchants log into every day.

The white label layer on top

That's where Clulo sits. Clulo runs the payfac-as-a-service model underneath a complete white label platform: the CRM, booking, and payments software your merchants use carries your brand, and the payments economics are yours. It's backed by software processing $300M+ per year, and every transaction runs on payment rails clearing billions in annual volume, settling through federally regulated sponsor banks: First Citizens Bank & Trust Company and JPMorgan Chase Bank, N.A.

The money works like this: your buy rate starts at 2.7% + $0.30 per transaction on the Scale plan. You set the retail rate your merchants pay, say 3.4%, and the spread is 100% yours, paid monthly. Your merchants apply under your brand, get approved, and bill the same day. Their statements carry your name, with powered by Clulo alongside your brand, which card network rules require anywhere your payments brand appears.

Which model fits you

• Become a payfac if you process billions and payments is your core business.

• Integrate a payfac-as-a-service API if you have an engineering team and your own software product that needs embedded payments.

• Launch on a white label platform if you want the payfac economics and the software, under your brand, without building either. That's what Clulo's white label payments is for, and the full rates, terms, and money flow are public on the page.

The founders winning in vertical SaaS stopped treating payments as someone else's revenue. The spread on every transaction your merchants process is either yours or your processor's, and payfac as a service is how you make it yours.
