How to catch your card processor quietly raising your rates and fees — the trick they count on you being too busy to notice. The math is third-grade arithmetic. The hard part is just doing it. Here's exactly how.
Want it done for you? Upload a statement and get an instant audit — nothing stored.
Run a free audit →Fee creep is the slow, quiet upward drift of what your payment processor charges you. A few basis points on the rate here, a new $20 “compliance” fee there, a $5 bump to the statement fee next month. Each change is small enough to slip past a busy owner — and that's the entire point. Stacked across a year and every line item, it's often hundreds of dollars a month leaking out.
Whole companies exist to audit this for you and charge up to 50% of the savings. You don't need them. You need two numbers and five minutes a month.
Compute this every month and write it down. If your sales volume and customer mix are roughly steady but this number keeps drifting up, you're being crept on. It rolls every sneaky tactic into a single figure that's hard to argue with. Three or four months in a row and the trend is obvious.
Split every statement into two piles. This is the whole game:
Interchange + assessments. This money goes to Visa & Mastercard — not your processor. It really does change twice a year (April & October). Not their fault, not their markup.
The processor's own margin: the discount rate over interchange, per-transaction fees, statement fees, “junk” fees. This is what your contract locks — and where creep hides.
When fees rise, the processor says “interchange went up.” Often true — but that's pile ①, which isn't theirs to mark up. Watch the markup (pile ②), not the gross total.
| Tactic | What you'd see | How to catch it |
|---|---|---|
| Markup creep | Discount rate 0.25% → 0.35% | markup $ ÷ sales × 10,000 = “bps”; compare to your contract |
| Per-item creep | $0.10 → $0.12 per swipe | per-item $ ÷ number of transactions |
| New junk fee | “PCI Non-Compliance,” “Regulatory Recovery,” “Network Access,” “Integrity Fee” appears | not on last month's bill + not in your contract = challenge it |
| Quiet fee bump | Statement fee $10 → $15 | read line items side-by-side vs. last month |
| Tier downgrade | More sales land in “non-qualified / mid-qualified” buckets | your rate didn't change but your mix did — the sneakiest one |
| Padded interchange | Interchange line higher than the published Visa/MC rate | compare to the public interchange tables |
| Filler fees | Monthly minimum, batch fee, PCI fee | are they even in your agreement? |
One statement on its own tells you almost nothing — every number looks plausible in isolation. Creep reveals itself the moment you line up this month next to last month next to your signed contract. $15 here, 4 basis points there — each below your annoyance threshold by design. Side by side across months, it's unmistakable. Keep your statements; compare them.

Total fees ÷ total card sales. Jot it next to last month's. Trending up on steady volume? Keep going.
markup $ ÷ sales × 10,000 = your bps. per-item $ ÷ transactions = your per-swipe. Higher than what you signed? That's a billing error, not a negotiation.
Anything on this bill that wasn't on last month's — or that went up — gets a circle.
Email your processor with the specifics (see the template below) and ask for a retroactive credit. Quietly-added fees are usually reversed the moment you name them.
“On reviewing my recent processing statement I've identified charges that depart from my agreed pricing. I'm requesting a credit for the overcharges below, applied retroactively to each affected period, plus correction going forward. Please confirm in writing the credit amount, the periods it covers, and the corrected fee schedule within 15 business days.”
Catching fee creep was never hard — it's arithmetic. Processors rely on the tedium, not the difficulty: long statements, tiny increments, renamed fees, and a busy owner who won't reconcile it line by line every month. Do the five-minute check, keep your statements, and dispute in writing. That's the entire service the audit firms charge a percentage for.
