From Software to Fintech: The SaaS Guide to Embedding Payments Seamlessly

• Embedded payments = user retention + revenue growth Eliminate redirects and clunky third-party flows to create frictionless in-app experiences.

• Two implementation paths: PayFac vs. PFaaS Learn which model fits your SaaS business best, own the infrastructure or partner with a provider.

• Make payments a product differentiator Go beyond processing to monetize transactions and deliver real-time value to your users.

• Finix powers faster, scalable launches With full-stack infrastructure and compliance handled, your team can stay focused on building.

Embedded payments let customers complete transactions directly within a SaaS platform, with no redirects, no handoffs to third parties, no confusing workflows. The result? A frictionless payment experience where the software and payment flow become one cohesive journey. Whether it’s a customer paying an invoice, a user buying credits, or a vendor getting paid out, it all happens in-app, under your brand.

Compare this to legacy integrations that rely on external gateways or third-party redirects, and the difference is night and day. Embedded payments streamline operations, reduce cart abandonment, and build deeper customer trust by making payments feel native to the product.

Let’s start with the obvious: revenue. Certain e-commerce and vertical SaaS companies have shown that embedded payments can dramatically boost revenue per user.

But it’s not just about money. Embedding payments delivers tangible value in other critical areas:

• Enhances the overall user experience by keeping transactions within the platform

• Reduces friction and builds trust by eliminating redirects to third-party payment pages

• Increases product stickiness, making users more likely to stay on the platform

• Supports operational efficiency by automating billing and reconciliation

• Provides real-time visibility into cash flow and transaction performance

With the right infrastructure, SaaS platforms can make payments a seamless part of the product, both for their users and their business.

Some SaaS companies choose to become a registered Payment Facilitator (PayFac) to bring embedded payments to life. This path offers full control over the entire payment experience and allows the platform to operate as its own payments business.

Becoming a PayFac means the platform takes on responsibilities such as:

• Managing merchant onboarding and underwriting

• Handling KYC (Know Your Customer) and compliance requirements

• Overseeing transaction monitoring and risk management

• Capturing a greater share of margin on each transaction

While this model offers significant flexibility and revenue potential, it also comes with complexity. Becoming a PayFac requires significant investment in licensing, infrastructure, and ongoing regulatory oversight.

The second path and the one we see most often at Finix is partnering with a PayFac-as-a-Service (PFaaS) provider. This approach allows SaaS platforms to:

• Embed fully branded, in-app payment experiences

• Avoid the burden of managing compliance, underwriting, and licensure

• Launch faster with reduced technical and regulatory complexity

• Scale easily as payment volume grows

• Keep product and engineering teams focused on building core features instead of maintaining payments infrastructure

Implementing embedded payments might sound complex, but with the right partner, it’s a smooth and scalable process. Here's how it works behind the scenes:

• Plug into the platform: Start by integrating APIs and SDKs to enable in-app payment capture. With Finix, you can choose a plug-and-play setup or build a fully customized experience.

• Capture payments securely: Use hosted fields or tokenization to collect card or ACH details in a PCI-compliant way, without ever touching sensitive data.

• Tokenize and authorize: Once captured, payment data is tokenized and securely stored. Transactions are authorized and processed through our direct network connections.

• Stay in sync with webhooks: Real-time webhooks notify your platform when payments succeed or fail, so you can trigger follow-ups, receipts, or UI updates automatically.

• Manage payouts and reconciliation: Handle refunds, vendor splits, and ACH payouts, all from one centralized dashboard with built-in reporting, risk tools, and compliance oversight.

Finix takes care of the heavy lifting, so your team can stay focused on delivering great product experiences, while unlocking a new way to monetize every transaction your platform processes.

• Make payments feel native: Ensure payment forms match your platform’s branding, fonts, colors, and tone, so the experience feels seamless from input to confirmation.

• Build reliable webhook handling: Design backend systems to gracefully handle retries, payment failures, and other edge cases without disrupting the user experience.

• Implement real-time fraud prevention: Use AI-powered tools to detect suspicious activity, reduce chargebacks, and protect both your platform and your users.

• Monetize strategically: Don’t just process payments, turn them into a revenue engine through transaction fees, premium payout features, or revenue sharing models.

The beauty of embedded payments is that SaaS platforms can now capture a slice of every transaction. Whether that’s via revenue sharing, flat fees, or premium features (like instant payouts), it opens the door to entirely new business models.

Passport, a mobility management platform serving cities, universities, and private operators, turned to Finix to modernize and embed payments directly into their software.

Before working with Finix, Passport’s payment infrastructure relied on multiple third-party providers, creating fragmented experiences for both end users and administrators. By embedding payments with Finix, Passport consolidated its payment stack, giving their customers a seamless, branded experience for paying parking fees, managing permits, and handling citations, all within the same platform.

With Finix, Passport gained:

• Full control over the payment flow and user experience

• Faster onboarding for their city and municipal partners

• Real-time visibility into transactions and payouts

• The ability to capture additional revenue from payment volume

By bringing payments in-house, Passport not only improved operational efficiency and compliance but unlocked a powerful new revenue stream, transforming their platform from a service provider into a true fintech partner for cities.
