Every processor promises lower rates. The quotes all look different on purpose — different models, different fee names, different "starting at" numbers — because offers you can't compare are offers you can't argue with. Here's how to line them up apples-to-apples, with nothing more than last month's statement and a pencil.

Rule one: compare effective rates, not quoted rates

A quoted rate ("as low as 1.69%!") describes your cheapest possible transaction — usually a debit card swiped in person. Most of your transactions aren't that. The only honest comparison is the one from our statement-reading guide:

Total fees ÷ total card volume = effective rate.

Ask every processor the same question: "Run my actual statement. What would my total fees have been, all-in, on this exact volume?" A real offer survives that question. A brochure rate doesn't.

Rule two: know which pricing model you're being sold

• Interchange-plus: the true card costs, plus one clear markup. The easiest model to audit — you can see exactly what the processor makes.

• Flat rate: one percentage on everything (common with phone-app processors). Simple and predictable, but shops with healthy volume often overpay for the simplicity.

• Tiered: transactions sorted into qualified/mid/non-qualified buckets, at different rates, sorted by rules you don't control. The hardest to compare and the easiest to inflate.

None of these is automatically wrong for your shop. But an offer that won't tell you plainly which model it is has told you something anyway.

Rule three: read the contract, not the quote

The quote is a month. The contract is years. Before you sign anything, find plain answers to these five:

1. How long is the term, and does it auto-renew?

2. Is there an early-termination fee — and how much, exactly?

3. Can rates or fees change mid-term? (On many contracts, yes — with "notice" buried in a statement message.)

4. Is the equipment free, leased, or purchased? A "free" terminal on a multi-year lease can cost more than the processing.

5. What does it cost to leave with your data — customer cards on file for your service plans included?

A processor who gets uncomfortable during these five questions is answering the sixth one for free.

The fee checklist

Whatever the headline rate, ask whether each of these appears, and how much it is: monthly statement fee, batch fee, PCI compliance fee (and the non-compliance penalty), monthly minimum, gateway or text-to-pay fee, chargeback fee, annual fee. Small lines, every month, for years — this is where cheap quotes get expensive.

What a straight offer looks like

It runs your statement, not a demo. It states your total cost, all-in, next to what you paid. It puts the term, the exit cost, and the markup in writing. And it stays just as good in month thirteen as it looked in the pitch — because the numbers were real when they were quoted.

That's the standard we hold our own free statement review to: your statement, side-by-side, plain numbers, and a straight answer if we can't beat what you have.

The bottom line

Don't compare promises; compare totals. Effective rate on your real volume, the pricing model in plain words, and five contract questions answered in writing. Do that, and the "best rate" stops being a slogan and becomes a number you chose on purpose.
