Merchant Statement Fee Dictionary: What Every Line Item Means

Every fee on a merchant statement falls into one of four categories: interchange, set by the card brands and paid to the cardholder’s bank; card brand assessments and network fees, set by Visa, Mastercard, Discover, and American Express; processor markup, set by your processor; and ancillary fees, added by your processor or its partners. Only the last two are negotiable.

That single distinction is the whole point of this page. Once you know which category a line item belongs to, you know whether there is anything you can do about it. Arguing about interchange is wasted effort. Arguing about markup and add-ons is not.

The four categories at a glance

Category	Who sets it	Negotiable?	Typically appears as	What you can actually do
1. Interchange	Visa, Mastercard, Discover, and American Express, published in public interchange tables. Paid to the bank that issued the customer’s card.	No. Identical for every merchant in the same category.	A long list of program names such as “CPS/RETAIL”, “MERIT III”, “EIRF”, “DATA RATE II”, or a single bundled “INTERCHANGE CHARGES” total.	You cannot change the rate, but you can reduce downgrades by fixing how transactions are captured and settled.
2. Assessments and network fees	The card brands themselves, for running the network and licensing the brand.	No. Pass-through, same for everyone.	“VISA ASSESSMENT”, “MC NABU”, “VI APF”, “DISCOVER DUF”, “FANF”, “ISA”, “CROSS BORDER”.	Verify they are billed at pass-through and not marked up. Ask for the brand fee schedule your processor is billing from.
3. Processor markup	Your processor or ISO, under your merchant agreement.	Yes. This is the negotiable part.	“DISCOUNT RATE”, “PER ITEM”, “AUTH FEE”, “QUALIFIED / MID-QUALIFIED / NON-QUALIFIED”, or nothing at all if it is buried inside a blended rate.	This is what a statement audit examines. It is also the part that can change without the card brands changing anything.
4. Ancillary and add-on fees	Your processor, its partners, or a third-party leasing or gateway company.	Often yes. Some are waivable, some are avoidable, some are penalties you clear rather than negotiate.	“STATEMENT FEE”, “MONTHLY MINIMUM”, “BATCH FEE”, “PCI NON-COMPLIANCE”, “REGULATORY PRODUCT FEE”, “GATEWAY”, “IRS REPORTING”.	Ask what each one funds. Fees that fund nothing you use are the first thing to raise in a renegotiation.

How to use this dictionary

1. Find the line item’s exact label on your statement. Statement wording varies by processor, so the same fee can appear under several names. The A to Z index near the bottom of this page maps the common variants.
2. Identify its category. Categories 1 and 2 are pass-through. Categories 3 and 4 are where your money is actually in play.
3. Check the near-duplicates table. Several fees look like the same charge billed twice and are not, and a few genuinely are two charges for closely related things.
4. Add up categories 3 and 4 only. That total, not the headline rate, is the number worth negotiating.

The entries below are grouped by category and sorted alphabetically within each group.

Category 1: Interchange

Interchange is the largest single component of what most merchants pay, and it is the one nobody can negotiate. The card brands publish these rates, the same rates apply to every merchant in a given business category, and the money goes to the bank that issued the customer’s card, not to your processor. What you can influence is which interchange program your transactions qualify for.

CPS program codes (CPS/Retail, CPS/Card Not Present, CPS/Small Ticket, and others): Visa’s names for its interchange programs, each describing a specific way a card was accepted and each carrying its own published rate. Pass-through. Not negotiable. May appear as “CPS/RETAIL”, “CPS/CNP”, “CPS/RETAIL 2”.

Data Rate I, II, and III: Mastercard’s interchange programs for commercial, corporate, and purchasing cards, where submitting more transaction detail (commonly called Level 2 and Level 3 data) qualifies the sale for a better program. Pass-through. The rate is not negotiable, but whether your system submits the extra data is a configuration question worth asking about if you sell to businesses or government buyers.

Downgrade (also shown as non-qualified or mis-qualified): A transaction that failed to meet the requirements of the interchange program it was expected to qualify for, so the card brand billed it under a more expensive program instead. Pass-through, but usually fixable. Frequent causes include keyed entry without address verification, settling a batch late, missing commercial card data, and accepting a rewards card in a category that does not qualify for a retail program.

EIRF (Electronic Interchange Reimbursement Fee): A Visa downgrade program a transaction lands in when it was authorized electronically but missed one or more qualification requirements, most often timely settlement. Pass-through. Not negotiable, but a high EIRF count is a strong signal that something in your batching or capture process needs attention.

Interchange fee: The portion of every card transaction that goes to the bank that issued the customer’s card, set by the card brand and identical for every merchant in the same business category. Pass-through. Not negotiable by anyone, including your processor.

Merit I, Merit III, and other Mastercard program names: Mastercard’s equivalent of Visa’s CPS codes, naming the interchange program a transaction qualified for based on how the card was accepted and what data accompanied it. Pass-through. Not negotiable.

Regulated debit interchange: The interchange charged on a debit card issued by a large bank covered by the Durbin Amendment, which limits what those issuers may charge. Pass-through. Not negotiable. Whether a given card is regulated depends on the size of the issuing bank, which is why two debit cards can cost different amounts.

Rewards, signature, and premium card interchange: The higher interchange programs that apply when a customer pays with a card that earns points, miles, or cash back, because the issuer funds part of those rewards from interchange. Pass-through. Not negotiable. This is the most common honest answer to “why did my average cost go up when nothing changed on my end.”

Standard interchange: The most expensive interchange program, and the fallback a transaction lands in when it fails the requirements of every better program. Pass-through. Not negotiable, but transactions repeatedly landing here usually point to a fixable process problem.

Category 2: Card brand assessments and network fees

These are the card brands’ own charges for operating the network and licensing their brands. Like interchange, they are pass-through and identical for every merchant. There are a lot of them, they have opaque acronyms, and several of them look like each other. That is what makes this category confusing rather than expensive. The thing worth verifying here is not the amount, which you cannot change, but whether the fee is being passed through at cost.

Acquirer Processing Fee (APF): A Visa fee charged on every authorization request, whether or not the sale is approved and whether or not it is later refunded. Pass-through. Not negotiable. May appear as “VI APF” or “ACQ PROCESSING FEE”.

American Express network fees: The assessments American Express charges on its own transactions, which reach your statement differently depending on whether you accept American Express through your processor’s program (commonly called OptBlue) or under a direct agreement with American Express. Pass-through. Not negotiable, though which acceptance arrangement you use is a decision worth reviewing.

Assessment fee: The card brand’s own share of every transaction, charged as a percentage of volume by Visa, Mastercard, Discover, and American Express on their respective sales. Pass-through. Not negotiable. May appear as “VISA ASSESSMENT”, “MC ASSESSMENT”, “DISC ASSESSMENT”.

Credit Voucher Fee: A Visa fee charged when you issue a refund, which is why processing a refund is not cost-free even though the sale itself is being reversed. Pass-through. Not negotiable. Worth knowing if you run a high-return business.

Cross-Border Fee and International Service Assessment (ISA): Mastercard’s and Visa’s respective fees for a transaction on a card issued outside the United States, which apply even when the customer is standing in your store. Pass-through. Not negotiable. These are two brands’ names for the same idea, not two charges on the same sale.

Data Usage Fee (DUF): Discover’s per-transaction network fee, roughly its counterpart to Visa’s APF and Mastercard’s NABU fee. Pass-through. Not negotiable.

Fixed Acquirer Network Fee (FANF): A monthly Visa fee based on your business type and number of locations rather than on how much you process, which is why it can appear in a month with little or no Visa volume. Pass-through. Not negotiable. If the location count looks wrong, that is worth correcting, since the fee is driven by it.

International Acquirer Fee (IAF): A second Visa fee on foreign-issued cards, billed alongside the ISA rather than instead of it. Pass-through. Not negotiable. This pairing is one of the most common sources of “why am I being charged twice for the same thing” on a statement, and in this case both charges are legitimate brand fees.

Kilobyte Access Fee (Base II Transmission Fee): A Visa fee based on the size of the settlement file your processor transmits, measured in kilobytes of data rather than in number of transactions. Pass-through. Not negotiable. It is unusual precisely because it is not billed per sale.

Merchant Location Fee: A Mastercard fee assessed per business location, typically billed annually or spread across the year, similar in logic to Visa’s FANF. Pass-through. Not negotiable, though the location count it is calculated from should match reality.

Misuse of Authorization Fee and Zero Floor Limit Fee: Two Visa penalty fees covering authorization hygiene, the first when an authorization is obtained and then never cleared or reversed, the second when a sale is settled without a matching authorization. Pass-through penalties. Not negotiable, but avoidable. Recurring charges here usually mean a terminal or gateway setting needs to be corrected.

Network Access and Brand Usage fee (NABU): Mastercard’s per-transaction network fee, charged on authorization messages and broadly comparable to Visa’s APF. Pass-through. Not negotiable. Read the label carefully: a line item called simply “network access fee” is not always this fee. See the category 4 entry below.

PIN debit network switch fee: The fee charged by the debit network that routed a PIN debit transaction, such as STAR, NYCE, Pulse, or Accel, set by that network and passed through to you. Pass-through. Not negotiable, although how transactions are routed among eligible debit networks can vary by processor and is a fair question to ask.

Transaction Integrity Fee (Visa) and Processing Integrity Fee (Mastercard): Near-identical penalty fees the two brands charge when a card-present transaction settles without meeting the brand’s data or timing standards. Pass-through penalties. Not negotiable, but avoidable, and they are one of the clearest signals of a capture or settlement problem rather than a pricing problem.

Category 3: Processor markup

This is the part of your statement that your processor sets, that varies from merchant to merchant, and that a statement audit is actually looking at. It is also the part that is hardest to see, because several common pricing models are designed to present markup and pass-through as one number.

Authorization fee: A per-authorization charge your processor adds on top of the network’s own authorization fees, sometimes billed on declines as well as approvals. Markup. Negotiable. Ask specifically whether it is billed on declines.

Basis-point markup (the “plus” in interchange plus): The percentage your processor adds to raw interchange under interchange-plus pricing, quoted in basis points and applied to every dollar you process. Markup. Negotiable. Under interchange-plus this figure is visible, which is the main argument for that pricing model.

Bill back, enhanced bill back, and Enhanced Recovery Reduction (ERR): Pricing models in which you are billed a headline rate at the time of the sale, and the difference between that rate and actual costs is charged back to you on a later statement. Markup structure. Negotiable, and the structure itself is worth negotiating, because the delay makes the true cost of any single month very difficult to read.

Blended or flat rate: A single percentage, sometimes with a per-item fee, applied to all card sales regardless of the underlying interchange. Markup structure. Negotiable. A blended rate is not automatically bad, but it does mean the split between pass-through cost and markup is not visible on the statement.

Discount rate: The headline percentage your processor charges on card volume. Under interchange-plus it represents markup only; under tiered or blended pricing it bundles interchange, assessments, and markup into one number. Markup, at least in part. Negotiable. What this number means depends entirely on your pricing model, which is why comparing two processors’ discount rates directly can be misleading.

Interchange padding: Billing an interchange line item at more than the card brand actually charged, so what looks like pass-through is partly markup. Markup presented as pass-through. Because Visa and Mastercard publish their interchange tables, this is one of the few statement questions with a checkable public answer. It is checked by comparing each interchange line item against the published table for that program.

Per-item (per-transaction) fee: A flat charge your processor adds to every transaction, separate from any percentage rate. Markup. Negotiable. It matters far more to a low-average-ticket business than to a high-ticket one, which is why the same pricing can suit one merchant and not another.

PIN debit markup: Your processor’s own charge on PIN debit sales, layered on top of the debit network’s switch fee and the applicable debit interchange. Markup. Negotiable. Worth separating from the switch fee, which is not.

Surcharge, dual pricing, or cash discount program fee: A monthly or per-transaction charge for running a compliant surcharge, dual pricing, or cash discount program, covering the configuration and ongoing rules monitoring such a program requires. Markup for a real service. Negotiable. Whether it is worth it depends on whether the program is actually configured and monitored correctly.

Tiered pricing (qualified, mid-qualified, non-qualified): A pricing model that sorts every transaction into a small number of buckets with different rates, where your processor, not the card brand, defines which transactions land in which bucket. Markup structure. Negotiable. The card brands have hundreds of interchange programs; a tiered model compresses them into a few, and the compression rule is set by the processor.

Voice authorization and AVS fees: Small per-use charges for phoning in an authorization or for running an Address Verification Service check on a keyed transaction. Markup. Negotiable, though AVS is often worth using on keyed sales because skipping it can cause an interchange downgrade that costs more than the fee.

Category 4: Ancillary and add-on fees

This is the category merchants usually mean when they say “junk fees.” That label is not always fair. Some of these fees fund something real, some fund something real that you are not using, some are penalties you can clear, and some are line items whose names imply an authority that is not behind them. The honest test is not the name of the fee. It is whether you can get a straight answer about what it funds.

Annual fee (membership fee): A once-a-year charge for maintaining the merchant account, often billed in a single month with no advance notice on the statement. Add-on. Frequently negotiable or waivable.

Batch fee (batch header fee): A charge applied each time you close out and settle a day’s transactions, which means a business that batches more than once a day pays it more than once a day. Add-on. Negotiable. If you batch multiple times daily, ask whether that is operationally necessary.

Breach protection or cyber liability fee: A recurring charge for a data-breach reimbursement program, frequently bundled with the PCI compliance fee and occasionally billed separately as well. Add-on for a real product. Sometimes negotiable. Ask for the coverage certificate, the deductible, and confirmation that you are not paying for it twice under two different labels.

Chargeback fee and retrieval request fee: Per-case charges for handling a disputed transaction, billed whether or not you ultimately win the dispute. A retrieval request is the earlier, lighter step, where the issuer asks for documentation before a formal chargeback is filed. Add-on. Sometimes negotiable. Not refunded when you win, which surprises most merchants the first time.

Early termination fee (ETF) or liquidated damages: A charge for closing the account before the end of the contract term, structured either as a set amount or as a formula based on the remaining term. Contractual. Negotiable at signing, and sometimes at renewal. Read whether your agreement auto-renews, because an evergreen renewal clause can restart the term you thought you were finishing.

Equipment lease: A separate agreement for your terminal, often held by a third-party leasing company rather than your processor, and frequently non-cancellable. Third-party contract. Usually not negotiable once signed, and typically not ended by closing the merchant account. This is the single most consequential item on this list to read before signing.

Gateway fee: A monthly and often per-transaction charge for the software layer connecting an online store, virtual terminal, invoicing tool, or recurring billing system to the processor. Add-on for a real service. Negotiable. Check that you are not paying for a gateway you no longer use.

IRS reporting fee (1099-K, TIN mismatch): A charge tied to the annual reporting of your card volume to the IRS, plus a separate penalty-style charge if the tax ID and legal business name on your account do not match IRS records. Add-on, with a penalty component. The reporting itself is a real obligation; the mismatch charge stops once the tax ID and legal name on the account are corrected.

Monthly minimum (discount minimum): A floor on what you pay in processing fees each month, where you are billed the shortfall if your actual fees come in under the floor. Add-on. Negotiable, and specifically painful for seasonal businesses, which pay it in exactly the months they process least.

Network access fee (processor-billed): A processor line item using wording similar to Mastercard’s Network Access and Brand Usage fee, but billed by the processor in addition to it. Potentially markup. Negotiable if it is a processor charge. The way to tell is to ask which card brand fee schedule it comes from; a genuine pass-through fee can be pointed to on a published schedule.

PCI compliance fee (PCI program service fee): A recurring charge for the tools and support that help you complete and maintain PCI DSS validation, typically covering a self-assessment questionnaire portal, quarterly network scans where your setup requires them, and often a breach reimbursement program. Add-on for a service that may be real. Sometimes negotiable. See the dedicated section below, and see our PCI compliance page.

PCI non-compliance fee: A separate, higher recurring charge applied when your PCI validation has expired or was never completed at all. Penalty, not a price. Not negotiated away, but cleared: it stops when you complete validation. See below.

Regulatory product fee (regulatory compliance fee): A processor line item whose name suggests a government requirement, although no regulator sets, requires, or collects it. Add-on. Negotiable. Ask what specific service or cost it funds; the answer varies by processor and is a reasonable thing to expect in writing.

Statement fee (paper statement fee): A monthly charge for producing and delivering your statement. Add-on. Often waivable, particularly if you switch to online-only statements.

Terminal rental, wireless, and help desk fees: Recurring charges for hardware you rent rather than own, for the cellular data plan on a wireless terminal, and for telephone support. Add-on. Negotiable. Check that every device still being billed is still in service; retired terminals are a common source of charges nobody noticed.

The PCI compliance fee, explained fairly

The PCI compliance fee is the single most disputed line item on merchant statements, and it has been an evergreen complaint among business owners for years. It is also the one where the “it is a scam” framing is only partly right, in a way that matters if you want the charge to go away.

What PCI DSS actually is. The Payment Card Industry Data Security Standard is a set of security requirements created by the card brands, not by a government agency. Every business that accepts card payments is required to validate compliance with it, usually once a year, and the obligation comes from your card acceptance agreement.

What the fee legitimately covers. For most small merchants, validation means completing a Self-Assessment Questionnaire, and depending on how you accept payments, running quarterly external network scans through an Approved Scanning Vendor. Processors commonly bundle a portal that walks you through the questionnaire, the scanning service where it is required, tracking of your validation status and expiry date, and frequently a breach reimbursement program. That bundle is a real service with real costs behind it. If you use it, the fee is buying something.

When it is not buying you anything. Two situations account for most of the frustration. The first is a merchant who has already validated independently, or whose environment does not require scanning, and who is still charged as though the full service is being used. The second, and more common, is that the charge on the statement is not a service fee at all.

The difference between the two fees, which is the part that gets missed. A PCI compliance fee is a charge for a service. A PCI non-compliance fee is a penalty for not having completed validation. They often appear under similar names, and merchants frequently negotiate hard against a charge that was never a price to begin with. A non-compliance fee is not reduced by asking for a discount. It stops when you validate.

How a merchant clears it.

1. Read the exact label. Determine whether your statement says compliance or non-compliance. They are different charges with different fixes.
2. Find out who your validation runs through. Your processor will name the portal and the vendor. Ask for the login and your current validation status and expiry date.
3. Complete the correct Self-Assessment Questionnaire. Which SAQ applies depends on how you accept payments, for example a countertop terminal on a dial or dedicated line versus an online checkout. Choosing the wrong one is the most common reason a submission is rejected.
4. Run the scan if your setup requires one. Not every merchant needs quarterly scanning; if you do, it runs through an Approved Scanning Vendor and has to pass, not merely be attempted.
5. Confirm the status changed. Ask for written confirmation that your account is marked validated, then check the next statement. A non-compliance charge that continues after validation is a billing error worth escalating.
6. Then, and only then, discuss the service fee. Once you are validated, the remaining PCI service fee is an ordinary add-on, and it is negotiable like any other.

More detail on the standard and what it requires of a small business is on our PCI compliance page.

Fees that look like duplicates but are not

Several statement charges look like the same fee billed twice. Some genuinely are two separate legitimate fees; others are a pass-through charge and a processor charge wearing similar names. This table covers the pairs that cause the most confusion.

These look like the same thing	What is actually going on	What to do
Assessment fee and APF or NABU	Both are card brand fees, but the assessment is charged on volume and the APF or NABU is charged per authorization. Two different bases, both pass-through.	Nothing. Both are legitimate.
International Service Assessment and International Acquirer Fee	Two separate Visa fees that both apply to foreign-issued cards, billed together rather than as alternatives.	Nothing. Both are legitimate Visa fees.
Mastercard NABU fee and a “network access fee”	NABU is a Mastercard pass-through fee. A separately labeled network access fee may be a processor charge on top of it.	Ask which published card brand schedule the second one comes from. A pass-through fee can always be pointed to on a schedule.
PCI compliance fee and PCI non-compliance fee	The first is a service charge. The second is a penalty for unvalidated status. They are not the same charge and they do not have the same fix.	Validate to end the non-compliance charge, then negotiate the service fee separately.
Visa Transaction Integrity Fee and Mastercard Processing Integrity Fee	Two brands’ versions of the same penalty, so both can appear in one month if the same problem affects both brands’ transactions.	Treat repeated charges as a settings problem, not a pricing problem.
Interchange downgrade and a non-qualified surcharge	The downgrade is a card brand cost. A non-qualified surcharge under tiered pricing is your processor’s charge applied on top of it.	Separate the two before assuming a spike in downgrades is entirely a brand cost.
Statement fee and monthly service or account fee	Often two separate flat monthly charges that both exist to cover account overhead.	Both are add-ons and both are fair game in a renegotiation.
Batch fee and per-item fee	A batch fee is charged once per settlement; a per-item fee is charged once per transaction.	Nothing improper, but the batch fee multiplies if you settle several times a day.
Equipment lease and terminal rental	A lease is usually a separate, often non-cancellable contract with a third party. A rental is normally a month-to-month charge from your processor.	Find out which one you signed, because closing the merchant account may not end a lease.
