Most businesses looking for a payment processor want to know two things before anything else: how fast can we start, and how much of the process can we own. These questions matter because payment processing sits at the center of revenue collection, and delays or limitations in that area create friction that affects everything downstream. Finix has built its platform around these concerns, offering software companies a way to embed payments directly into their products while retaining control over branding, fees, and merchant relationships.
The company raised $75 million in Series C funding in October 2024, with the round led by Acrew Capital and co-led by Leap Global and Lightspeed Venture Partners. Citi Ventures and Tribeca Venture Partners also participated. That brings total outside funding to more than $200 million, and according to company reports, revenue has quadrupled over the past year.
Who Finix Serves
Software platforms that want to offer payment processing as part of their product represent Finix's primary audience. This includes companies in hospitality, parking management, membership services, and automotive industries. Lunchbox, Clubessential, Passport, and Vroom all use Finix to handle payments within their own platforms.
The setup allows these companies to present payment processing under their own branding. Merchants onboarded through these platforms see the software company's name and design rather than a third-party processor. This white-label approach extends to dashboards, fee structures, and reporting.
What Payment Providers Look Like in Practice
When businesses compare payment platforms, they often look at how quickly they can start processing and how much control they retain over fees and branding. Stripe and Adyen offer broad toolkits, but software companies building payments into their own products sometimes need more granular control over merchant onboarding and revenue splits. A detailed Finix review shows how the platform addresses this by letting businesses white-label the entire payment flow, from onboarding to branded dashboards, while handling compliance on the backend.
Finix processes more than 400 million transactions per day and holds direct connections to Visa, Mastercard, American Express, and Discover. Businesses can begin accepting payments in a single day using as few as 3 API endpoints, which removes some of the setup friction common with older processors.
Getting Started Without Code
Finix offers no-code tools that handle common payment functions. Recurring billing, tokenization, virtual terminals, and real-time payouts are all available without building custom integrations. For businesses that want to move quickly, this reduces the time between signing up and processing actual transactions.
The platform supports both online and in-store payment acceptance across the United States and Canada. Companies can choose how deeply they want to integrate. Some use the no-code options to start immediately, while others build custom implementations using the API endpoints.
API Structure
Developers working with Finix can begin processing payments using 3 API endpoints. This minimal setup covers basic transaction handling and works as a starting point for more complex implementations. Additional endpoints cover merchant onboarding, reporting, refunds, and payouts.
The API documentation includes sandbox environments for testing. Companies can run test transactions, build out their integration, and verify functionality before going live with real card networks.
Compliance and Security
Finix maintains PCI Service Provider Level 1 certification, the highest level of certification available for payment processors. The company also holds SOC 1 and SOC 2 compliance, which addresses controls related to financial reporting and data security.
These certifications matter because they shift compliance burden from the software platform to Finix. Companies embedding payments into their products do not need to maintain their own PCI certification at the same level, since Finix handles the sensitive card data.
Custom Fee Settings
One feature that software platforms find useful is the ability to set custom fee structures for merchants. Rather than passing through a standard rate, platforms can configure their own pricing. This creates a revenue stream for the software company and allows them to price payments as part of a broader service offering.
The fee customization extends to different transaction types. Platforms can set different rates for card-present versus card-not-present transactions, or vary pricing by merchant category. This flexibility supports platforms serving multiple industries or merchant types.
Merchant Onboarding
Finix handles merchant onboarding on behalf of software platforms. This includes identity verification, risk assessment, and compliance checks. The process runs under the platform's branding, so merchants do not interact with Finix directly during signup.
The onboarding workflow can be customized to match the platform's requirements. Some companies want a minimal application process to reduce friction, while others need additional information for their own risk management. Finix supports both approaches.
Real-Time Payouts
The platform includes real-time payout functionality. Instead of waiting several days for funds to settle, merchants can receive money immediately after a transaction. This feature benefits industries where cash flow timing matters, such as gig economy platforms or service providers with daily expenses.
Payouts work with existing bank accounts and do not require special enrollment. The platform handles the transfer mechanics while the software company controls when and how payouts occur.
What Users Say About Finix
Customer feedback tends to focus on pricing and support. One CEO described Finix as having "best rates in the game, amazing customer service," adding that they had never encountered problems with the platform. CharityStack's CEO highlighted flexibility as the primary factor in choosing Finix over other options.
These comments come from businesses that have used the platform in production environments. The emphasis on rates and service quality suggests that operational reliability and cost competitiveness are the main factors driving satisfaction.
The Verdict: A Platform Built for Platforms
Finix works well for software companies that want payment processing under their own brand. The combination of white-label capabilities, custom fee structures, and streamlined merchant onboarding addresses common needs in this market. Direct card network connections and high transaction volumes indicate operational stability.
For businesses that need full control over the payment relationship with their merchants, Finix provides the infrastructure to make that possible without building a processing network from scratch. The funding and revenue growth suggest the company has resources to continue development and support.
