Before you decode a single line, find out who set up your account

The company that sold you your merchant account is usually not the processor named on your statement. It is an ISO, and there is no exam, licence or education requirement to become one. In our audits, more than 90 percent of accounts are not set up correctly, and that is where it starts.

What is an ISO in payments, and why it shows up on your bill

Why merchant statements are so difficult to understand

A credit card processing statement may combine card-brand interchange, network assessments, processor markups, gateway charges and monthly account fees in one document. The descriptions are often shortened into codes that make perfect sense to the companies collecting the money, and almost nobody else.

This guide walks you through how to read your merchant statement, translating those line items into plain English. It also helps you distinguish between costs that are generally established by the card brands and charges that may have been added or marked up by your processor.

The four main types of statement charges

Knowing which party is responsible for a charge is the first step toward understanding whether it can be reduced.

Interchange

Fees tied to the card, transaction method, industry, data quality and other qualification rules.

Card-brand fees

Assessments and network charges associated with Visa, Mastercard, Discover or American Express.

Processor fees

Markup and account charges imposed by the company providing or reselling the processing service.

Third-party fees

Charges connected to gateways, software, fraud tools, POS systems and other outside providers.

The Part They Leave Off the Brochure

Your Processor Has a Score. Do You Know It?

Decoding a fee tells you what one line means. It will not tell you about the holds, the lawsuits, the quiet markups or the record behind your processor’s logo. We score every major processor independently, and none of them can pay to change the result.

Common merchant statement questions

Why are there so many different fees on my processing statement?

A single statement can include interchange categories, card-brand assessments, network fees, processor markup and third-party service charges. The number of line items increases when a business accepts several card types or processes transactions through different channels.

Does every fee belong to Visa or Mastercard?

No. Some fees originate with the card brands, while others are imposed or marked up by the processor, gateway, software provider or another party. Correctly identifying the source is essential before deciding whether a charge is negotiable.

Can I lower my fees without changing processors?

Often, yes. Depending on the account, savings may come from correcting pricing, removing unnecessary charges, improving transaction data or restructuring the existing agreement rather than replacing the processor.

Why does my effective rate change from month to month?

Your card mix, transaction method, ticket size, refunds, commercial-card volume and interchange qualification can all change. Processor-added fees and pricing increases can also move the effective rate.

How can I tell whether a fee is legitimate?

The description alone is rarely enough. You need to identify who imposed it, compare the amount with the underlying rate or transaction count and determine whether the processor has added a markup.
