Payments used to sit at the edge of vertical software. A bolt-on, a checkbox, something a third party handled while your team stayed focused on the product. That is changing fast. For a growing number of software companies, payments are now central to the roadmap, the revenue model, and the customer relationship.
That shift puts a strategic decision in front of software leaders. Do you become your own payment facilitator and build the infrastructure yourself, or do you partner with a PayFac as a Service provider and reach the same outcome without the buildout? The answer shapes your cost structure, your speed to market, and how much of the payments upside you keep.
This is not an argument for one path over the other. It is a clear look at what becoming your own payment facilitator actually costs, so you can make the call with your eyes open.
What a payment facilitator actually does
Before you weigh the cost of becoming one, it helps to be precise about what a payment facilitator is responsible for. A payment facilitator, or PayFac, sits between merchants and the card networks, and it owns a set of functions that are easy to underestimate from the outside.
- Merchant onboarding and underwriting. Every merchant has to be vetted, risk scored, and approved before it can process a single transaction.
- Risk and fraud monitoring. Transactions need ongoing surveillance to catch fraud, flag anomalies, and protect the wider portfolio.
- PCI compliance. The security standards that govern how card data is stored, processed, and transmitted have to be met and maintained.
- Funding and settlement. Money moves from the card networks to merchant bank accounts on a reliable, predictable schedule.
- Chargeback and dispute handling. When a customer disputes a transaction, someone has to manage the representment process.
- Reporting and reconciliation. Merchants and internal teams need a clear view of transactions, payouts, refunds, and fees.
Each of these is a discipline in its own right. Owning all of them at once is what becoming a payment facilitator really means.
The build path, and what it actually costs
Building your own payment facilitator is possible, and plenty of companies have done it. But the cost shows up in four places, and only one of them is money.
Compliance and registration. You need sponsorship from an acquiring bank and registration with the card networks. You also need to reach and maintain PCI DSS Level 1, the most rigorous tier of payment security, which brings its own assessment, documentation, and continuous obligations.
Technology and integrations. Processor connections, a settlement engine, onboarding flows, risk tooling, and reporting all have to be built or bought, then maintained. This is not a one-time project. Payment infrastructure needs continuous engineering attention long after launch.
Operations and people. Underwriting, risk, and compliance cannot be fully automated. You need people who understand merchant risk, dispute handling, and the rules that govern money movement. Hiring and keeping that expertise is a standing cost, not a one-time hire.
Time. This is the cost leaders tend to underestimate most. Standing up a compliant payment facilitator operation typically takes many months before a single transaction clears. That is time your product roadmap is not moving and your payments revenue is not flowing.
For a company with the scale, the risk appetite, and the internal expertise to run a payments operation, building can make sense. For most vertical software companies, the buildout competes directly with the core product for engineering time and capital, and it rarely wins that competition on merit.
The partner path: PayFac as a Service
There is a second route to the same destination. PayFac as a Service lets a software company embed payments, and share in the upside, without building or operating the underlying infrastructure.
You integrate once. The provider carries the parts that are expensive to build and risky to run, so compliance, underwriting, risk monitoring, and settlement all happen behind the scenes. You keep control of the customer-facing experience, which means embedded payments feel native to your product instead of bolted on.
The practical difference is speed and focus. You reach the market in a fraction of the time, you skip the compliance and risk buildout, and your engineering team stays pointed at the product your customers actually pay you for. Payments become a profit driver rather than a cost center, without turning into a second business you have to run.
How to decide: five questions to weigh
The right answer depends on your situation. These five questions cut to the heart of it.
- What is your processing volume today, and realistically in two years? Scale changes the economics of building.
- Do you have in-house risk and compliance expertise? If not, hiring it is part of the true cost of building.
- How quickly do you need to be live? Speed to market often settles the question on its own.
- How much control over the merchant experience do you need? Both paths can preserve it, but the details differ.
- Does your vertical carry specific requirements? Specialized industries tend to benefit from a partner that already understands them.
If your answers point toward speed, focus, and keeping your team on the product, PayFac as a Service is usually the stronger path. If you have the scale and the appetite to run payments as its own operation, building may be worth the investment.
