The processing industry runs on confusion. We're flipping it.

How the industry actually makes money

Every card transaction has a true wholesale cost: interchange, set by the card networks and paid to the cardholder's bank, plus small network assessments. These rates are published, they update on a regular schedule, and every processor in the country pays exactly the same amount for the same transaction. There is no volume discount, no insider rate, no negotiation.

That means the only thing a processor actually controls — and the only place it makes money — is the markup it adds on top. And here's the uncomfortable part: the easiest way to grow a markup isn't to earn it. It's to hide it.

The traditional playbook has a few well-worn moves. Bundled and tiered pricing collapses hundreds of published interchange rates into vague buckets like "qualified" and "non-qualified," so you can't see where wholesale ends and markup begins. Rate drift adds a few basis points a year — small enough that no single statement raises an alarm, large enough to compound into real money. And junk fees — statement fees, PCI non-compliance fees, batch fees, "regulatory" fees — pad the bill with line items most owners never question because they sound official.

None of this is illegal. Most of it is disclosed, technically, in fine print or a statement insert. It works precisely because business owners are busy running businesses, not auditing statements.

Why nobody big will tell you this

Here's a question worth sitting with: if a free tool that shows businesses what they should be paying is so obviously useful, why hasn't a major processor built one?

Because they can't. A large processor or sales organization that handed its merchants a transparent fee-checking tool would be auditing its own book of business. Every merchant who ran the numbers and discovered an inflated markup would be a support call, a renegotiation, or a cancellation. The traditional model doesn't just tolerate uninformed merchants — it depends on them.

This is why the loudest voices in the industry talk about hardware, software, and "solutions" — anything but the actual per-transaction economics. The confusion isn't a bug in the industry. For most of it, confusion is the product.

What we're flipping

CheckMyFees was built on the opposite bet: that a business owner who understands their fees is worth more as a customer than one who doesn't. So we made the tools the industry never would — free, anonymous, and with no sales contact of any kind.

There are four main ways processing can be priced — flat rate, cost plus, cash discount, and surcharge — and each one distributes the cost differently between your business, your customers, and the processor. The right answer depends on your business, not on which program pays the processor the most. Our Who Pays? comparison tool shows all four side by side so you can see exactly where every dollar goes.
