Been diving into the PayFac space lately and noticed something interesting happening with how platforms are approaching embedded payments. The economics here are wild—companies used to face a brutal choice: either spend 12-24 months and over a million bucks building their own payment infrastructure, or find a partner and launch in 4-8 months. Unsurprisingly, most software vendors are picking option two.

What's really changed the game is that among the largest payment facilitators now offering as-a-service models, you've got players like Finix, Tilled, Worldpay for Platforms, Exact Payments, Stax Connect, and VoPay all competing hard to make this accessible. The data backs it up—91% of independent software vendors now expect embedded payments to drive their growth over the next year.

Take Finix for example. They raised $208 million, including a hefty $75M Series C last October from Acrew Capital. What makes them different is they've got direct connections to American Express, Discover, Mastercard, and Visa. No middleman layers adding latency or cost. They're positioning themselves as a bridge—start with PayFac-as-a-Service, then transition to full PayFac ownership down the line if you want. Their CEO mentioned that Stripe only holds about 6% of the US market and less than 2% globally. That's telling you something about how fragmented payments still are.

Then there's Tilled, which came out of Boulder in 2019 and has been on an absolute tear—550%+ year-over-year growth. What caught my attention is their focus on transparency. They're letting platforms keep the majority of payment revenue while handling the compliance nightmare on their end. Merchant onboarding takes under 10 minutes for most applicants. Just announced a partnership with KORT Payments too, expanding their reach across US and Canada.

Worldpay for Platforms (formerly Payrix) is the enterprise play here. They process transactions for 75% of Mastercard PayFacs, which tells you they've got serious card network integration. If you're running a complex operation with international requirements, this is probably your option. Real-time dashboards, white-label capabilities, the whole enterprise stack.

Exact Payments is handling nearly a billion transactions annually. They work with Chase, Ordway, Cineplex, and others. What's clever about their approach is processor-agnostic flexibility—you can work with existing banking relationships or pick processors based on what works for you. They're saying platforms can go live in days, not months.

Stax Connect has been around since 2014 and processes over $23 billion annually. They just launched Stax Processing in October 2025, completing their shift to a full-stack processor. A Forrester study they commissioned found that vertical software platforms can generate an estimated $900,000 in additional revenue through embedded payments. The partnership models are flexible too—referral, reseller, or PayFac options depending on what matches your business.

VoPay is the cross-border specialist. They launched their Cross Border Payments-as-a-Service platform in April 2025, covering 140+ countries. If you're serving international merchants or customers, this matters. They can get you up and running in as little as 2 weeks with 250+ API endpoints.

What's worth noting is the speed differential. Tilled and VoPay are emphasizing rapid deployment—sub-10-minute merchant onboarding versus 2-week platform integration. Exact Payments is talking days. Worldpay will take longer but gives you enterprise-grade infrastructure.

Geographically, most of these providers focus on US and Canada except Worldpay, which has broader international reach. If you've got strong development teams, the API-first approaches from Exact, Tilled, and VoPay will appeal more. Finix actually offers both code and no-code options if your team isn't as technical.

The revenue sharing varies too. Tilled pushes transparent pricing with platforms keeping most of the revenue. Exact Payments offers flexible models tied to your transaction volume. You'll need to run the numbers with each based on your projected volume.

The real story here is that embedded payments have shifted from a cost center to a genuine revenue opportunity. Building in-house is still theoretically possible but you're looking at serious capital, compliance expertise, and constant maintenance. The PayFac-as-a-Service route gives you market speed with lower upfront investment, which is why we're seeing this sector project growth through 2034 and beyond.
