How to read a merchant processing statement (and spot the markup)

Most merchants we talk to admit they do not actually read their monthly processing statements. That is not laziness - it is by design. Statements are written in jargon, mix wholesale costs with markup, and bury the numbers that matter under the numbers that do not. Here is how to actually read one.

Every statement has four components

No matter who your processor is, what you pay each month breaks down into the same four things. Once you know what to look for, the line items stop being mysterious.

1. Interchange

This is the wholesale cost your processor pays to the card-issuing bank. Visa and Mastercard publish the rates twice a year and every processor pays the same. It is the largest piece of your bill, typically 1.5% to 2.5% of the transaction depending on the card type. You cannot lower interchange. Any processor claiming they can is bending the truth.

2. Card brand assessments

Small fees Visa, Mastercard, Discover and American Express add on top of interchange. Usually around 0.13% to 0.15% of volume plus a few cents per transaction. Like interchange, these are wholesale and the same for every processor.

3. Processor markup

This is the only piece your processor controls, and the only piece you should be shopping. With interchange-plus pricing the markup is stated plainly: a fixed percentage plus a fixed transaction fee. With tiered pricing the markup is hidden inside the tiers, which is the whole point of tiered pricing existing.

4. Account-level fees

Monthly statement fee, batch fee, PCI compliance fee, monthly minimum, gateway fee, IRS reporting fee, annual fee. Each of these is small individually but they add up fast. Some are unavoidable (statement fee). Some are pure profit for the processor (PCI non-compliance fee, which we will get to).

How tiered pricing hides the markup

Tiered pricing buckets every transaction into one of three categories: qualified, mid-qualified, and non-qualified. The qualified rate looks attractive on the first page of the statement. The problem is that very few transactions actually qualify for the qualified rate. Most land in mid-qualified or non-qualified, which carry significantly higher rates - and that is where the processor pads the margin.

On a tiered statement, look past the front page to where it breaks volume down by tier. If most of your volume is sitting in mid-qual or non-qual, you are not getting the qualified rate you think you are.

Five red flags worth circling

  • "PCI Non-Compliance Fee" - if you see this, it almost always means you never completed your annual PCI questionnaire. The fix is free (it takes 20 minutes) but the fee can be $20-40/month if ignored.
  • Big variance in your "effective rate" month-to-month - divide total fees by total volume to get your effective rate. If it bounces between, say, 2.4% and 3.1% with no real change in business, your pricing is tiered and unpredictable.
  • "Enhanced bill-back" or "ERR" line items - these are after-the-fact downgrades that get added in the next billing cycle. Designed to be impossible to forecast.
  • Equipment lease line items - it often does not make sense to lease a terminal. Buy outright (typically a few hundred dollars) or confirm the lease program is fair. If not, a 48-month lease on a $300 terminal often costs $2,000+. We only work with lease programs that are actually in your favor.
  • An IRS Reporting Fee or "annual fee" - usually $99-199 charged once a year. Most can be waived if you ask.

What to do once you understand your statement

The honest test: calculate your effective rate (total fees divided by total volume). If it is above 2.5% for a typical retail business or above 3% for an eCommerce business, there is likely room to lower it. If it is well below those numbers, you are probably already on a competitive program.

Either way, the next step is to have someone independent read the statement and tell you. Send us a recent statement and we will mark it up line by line, show you exactly where the markup is, and tell you whether a switch would actually save you enough to be worth doing. If it would not, we say so on the first page.
