Why is my processing rate higher than what I was quoted?

Start by measuring the gap rather than arguing about it.

Compute your effective rate

Add every charge on the statement — all of it, including monthly, compliance and equipment lines — and divide by total card volume. That percentage is what you pay. Do it for three consecutive months, because card mix moves and one month is not evidence.

Then find where the difference comes from

The gap measured on a statement

Notice what happened. The markup came to exactly the quoted 0.30% plus a dime. The quote was honoured in full and the bill is 2.67%, because the quote described $383 of a $2,303 charge.

Three effective rates between 2.67% and 2.90% under one unchanged contract. That range is what you are working inside before deciding anything is wrong.

Where the money actually is

The same figures show what is worth fixing, and in what order.

Cutting the markup from 0.30% to 0.15% saves about $130 a month on the busy month, roughly $1,555 a year. Worth doing, and it is what every competing salesperson will offer.

The card mix swing between the two identical-volume months was $198 a month, about $2,376 a year, and no processor controls it.

So: fix the acceptance practice first because it is free, then negotiate the markup, then compare providers.

What a flat rate costs on the same month

A flat-rate quote of 2.9% plus $0.30 on that busy month is $2,877.60 — an effective 3.33% against 2.67% on interchange-plus. About $574 a month, or $6,893 a year, on identical volume.

Flat rate buys simplicity and a predictable number, and on low volume with small tickets that trade is often worth making. As volume grows, interchange-plus usually wins, because you stop paying an averaged price for the cheapest transactions you accept. The crossover is a calculation rather than an opinion: run your own three months both ways.

What to ask for

1. Three months of statements, and your own effective rate calculation for each.
2. A rewrite to interchange-plus, with the markup stated as a percentage plus a per-item amount, in writing.
3. An itemised list of every recurring fee and what it buys.
4. Confirmation of whether your terminal is leased, on what term, and what the buyout is. Equipment leases frequently sit with a separate company and survive a change of processor.
5. Your merchant category code, checked against what you actually sell.

Before you switch

Switching solves a markup problem. It does not solve a card mix problem, a keyed-entry problem or a late-batch problem, and those follow you to the next provider. Work out which part of the gap is markup and which part is your own acceptance practice, because only one of them is on the contract.

Why this ends up in a funding file

Your processing statement is an underwriting document. A funder reading it sees monthly volume, transaction count, average ticket, chargeback ratio and the fees you pay — and those fees come straight out of the margin available to service any advance. Cutting a point off your effective rate improves the file as well as the bank balance.

There is a second reason to care. Where an advance is collected by split funding at the processor, changing processors can be an enumerated event of default under the funding agreement, whatever the new processor's salesperson says. If you have an active advance, read the agreement and ask for written consent before you switch anything.
