Payments Infrastructure: What Founders Get Wrong (and How to Fix It)

For early-stage fintech and SaaS startups, payments are often treated like a plug-and-play utility. Just pick a PSP, slap on a checkout, and go. But under the hood, how you set up your payments stack has massive implications for your margins, customer experience, and scalability.

Here are the most common mistakes founders make with payments infrastructure—and how to fix them before they become liabilities.

1. Overcomplicating Payment Flows

It's tempting to support every method: cards, ACH, wallets, crypto. But too many options too early adds friction and maintenance overhead.

Fix: Start with what your primary customers actually use. Design a clean, simple flow. Add complexity only when demand (and volume) justifies it.

2. Ignoring Reconciliation

Revenue is great. Knowing where it is, what fees were taken, and when it will arrive is better. Many startups run blind here.

Fix: Use PSPs with strong reconciliation tools or build basic internal reports that map money in vs. payouts vs. fees. Investors love teams that know their numbers.

3. Underestimating Regulatory Exposure

In some markets or models, you're not just a software company. You're handling money, which brings obligations.

Fix: Check if you need EMI licensing, registration, or reporting (especially in the EU or Israel). If not, ensure your PSP is the regulated party and your contracts are clear about that.

4. Single Points of Failure

Founders often fall in love with one provider. Then that provider freezes funds, raises fees, or experiences downtime—and you're stuck.

Fix: Set up a secondary PSP early. Even if it only handles 5% of volume, you’ll sleep better.

5. Not Thinking About Margins

If you run on thin margins and payment fees eat 2.5% per transaction, that's not sustainable at scale.

Fix: Model your fees, payouts, and net revenue per transaction. Small optimizations (settlement frequency, currency conversion, routing) can unlock serious gains.

Final Thought

Payments aren’t just a tech decision. They’re part of your product, revenue model, and risk profile. Treat them as infrastructure from day one.
