When it comes to accepting payments — whether online or in-store — many businesses think they know what they’re being charged. But the truth is, most small business owners and entrepreneurs are unknowingly paying more than they should in PSP (Payment Service Provider) fees.

If you’re using Stripe, Square, PayPal, Clover, or any other PSP, this post is for you.

The Hidden Complexity of Payment Fees

At first glance, payment processing seems simple:

 - You pay a small percentage and a fixed fee per transaction. That’s it… right?

Not quite.

In reality, your true payment cost can include:

  • Processing fees (percentage + fixed fee)
  • Currency conversion (FX) margins
  • Platform surcharges or monthly fees
  • Terminal rental or hardware costs (for in-person payments)
  • Chargeback fees or reserve holds

These charges add up — and your effective rate (what you’re really paying per dollar processed) is often much higher than what your provider advertises.

Real Example: E-Commerce Business
 

Let’s say you’re using Stripe to accept online payments:

Monthly volume: $20,000
Average transaction: $50
Stripe advertised fee: 2.9% + $0.30
 

Looks reasonable? Now factor in:

Currency conversion at 1–2%
Micropayment penalty if your average ticket is low
Additional platform or plugin fees (e.g., Shopify)

You may end up paying closer to 4–5% overall.
