A large retailer processing $50 million per year pays a fraction of a percent more than actual interchange costs. A small business doing $500,000 per year often pays 2-3x more than that. The payment processing industry is structurally designed to extract more from small businesses — whether you run a retail shop, a B2B or franchise operation, or anything in between — and most small business owners don't know it's happening.
Here's why it happens and what you can do about it.
They start with flat-rate pricing and never leave
The most common first processor for small businesses is Square or Stripe. Both use flat-rate pricing: one simple percentage on every transaction. No contract, no monthly fee, easy setup.
For a new business processing $3,000 a month, the simplicity is worth the premium. But many businesses outgrow flat-rate pricing without realizing it. Once you're processing $10,000-$15,000 per month, the difference between flat-rate and interchange-plus can be $200-$400 per month.
Most business owners don't do that math. They stay on Square because switching feels like hassle, and because nobody is proactively showing them the alternative.
They don't know what "good" looks like
Ask most small business owners what their effective processing rate is, and they'll tell you the rate their processor quoted them — not the actual percentage of revenue they're paying in fees. These are very different numbers.
Your effective rate is total fees divided by total volume. For in-person businesses on interchange-plus, a good rate is 1.7%-2.3%. For online, 2.3%-2.8%. If you're on flat-rate pricing, you're almost certainly above these benchmarks.
Without knowing what good looks like, you have no basis for knowing whether you're being overcharged. Processors count on this.
Their contracts have rate escalation clauses
Many traditional processors (the ones that call your business and offer a "better deal" than Square) put merchants on tiered pricing with opaque rate structures. They quote you a "qualified rate" of 1.79% and don't mention that most of your transactions will land in the "non-qualified" bucket at 3.5%.
On top of this, some contracts include clauses that allow the processor to raise rates with 30 days' notice. By month six, you're paying significantly more than you were quoted, but you're locked in with an early termination fee.
Interchange-plus pricing protects against this. The processor's markup is fixed. The only thing that changes is interchange itself, which the card networks set publicly.
They pay for hardware they shouldn't
Equipment leasing is one of the most profitable products in the payment processing industry — for the processor. A terminal that costs $200-$400 to purchase is often leased for $35-$50 per month on a 48-month agreement. That's $1,680-$2,400 for a piece of hardware worth a fraction of that, with no option to cancel.
When the lease ends, the terminal is outdated. The salesperson is back to sign you for another lease on the new model.
Own your hardware or get it provided as part of a processing agreement. Never lease.
They don't audit their statements
Processing statements are dense, full of codes, and formatted to discourage close reading. Most business owners look at the total deducted and move on.
But that total often includes 5-10 line items that are negotiable or unjustifiable: statement fees, batch fees, PCI fees on a completed account, "regulatory" fees, minimum monthly fees. Each one is small. Together they can add up to $50-$150 per month in extra charges.

They don't ask for rate reviews
Processors set rates based partly on your negotiating behavior. If you've never called to ask for a rate review, you're almost certainly not getting the best available rate.
If you're on interchange-plus, the markup portion — the percentage and per-transaction fee your processor charges on top of interchange — is negotiable. Processors compete on this margin. Call your rep and ask them to review your rates. If they won't budge after a year of good processing history, that's information too.
What you can do about it right now
Calculate your effective rate. Pull your last statement, find total fees and total volume, divide. If you're above 2.5% for in-person sales, you're overpaying.
Request a statement audit. Send your statement to Clearo and we'll do a line-by-line review showing where you're overpaying and what interchange-plus pricing would cost on your actual volume.
Switch to a processor with no cancellation fees. If there's no exit cost, there's no risk in making the comparison. See our case studies to read how real businesses made the switch and what they saved.
