How to read a merchant processing statement: volume, fees, reserves and deposits

What a processing statement is

A processing statement, also called a merchant statement, is the record your payment provider issues for each period, usually a month. It shows the card payments you took, the refunds and chargebacks that came back, every fee that was deducted, any money held back, and the deposits paid to your bank account.

Layouts differ from provider to provider and the same item can carry different names. The pages below describe what to look for, not one provider’s format. Where a line is unclear, ask the provider to explain it in writing.

Read it in three passes

• The summary: total card sales, the number of transactions, refunds, chargebacks, total fees and the net amount paid out.
• The deposits: each payout to your bank account, with the date and the batch of sales it covers. Check them against your bank statement for the same dates.
• The fees: the detailed lines behind the total fees figure, often split by card brand and card type, plus monthly, per-item and one-off charges.

If the deposits on the statement do not add up to the deposits on your bank statement, look for money held back, fees taken from a later payout, or chargebacks debited on a different day, before anything else.

The fees: what the card networks publish and what the provider sets

Fee lines usually fall into three groups. Interchange goes to the bank that issued the customer’s card. Network or assessment fees go to the card networks. The provider’s own charges are its markup: a percentage, a per-transaction amount, monthly fees, and fees for chargebacks or other events.

Visa publishes its US interchange tables. The edition with rates effective 18 April 2026 says that merchants do not pay interchange reimbursement fees: merchants pay a merchant discount to their financial institution, and that discount can include a variety of processing services. Your statement may show interchange as separate lines, or only one combined rate, depending on how the offer is priced.

For debit cards, a federal rule applies. Regulation II, as shown in the Electronic Code of Federal Regulations on 20 October 2026, limits the interchange a covered issuer may receive on a debit transaction to 21 cents plus 0.05% of its value (12 CFR 235.3), plus up to 1 cent if the issuer meets the fraud-prevention standards (12 CFR 235.4). Issuers that, with their affiliates, hold less than $10 billion in assets are exempt (12 CFR 235.5). The Federal Reserve Board’s Regulation II page lists a proposal to lower the cap; the regulation’s text opened on the same day still sets the figures above.

Credit card interchange is not capped by Regulation II and Visa publishes many more programmes and rates for it. What the table shows is that the same purchase can carry very different interchange depending on the card, which is one reason the fee total moves from month to month even when your sales do not.

Zolution’s payment terms page explains the terms used in offers, such as the processing fee, the fixed transaction fee and the rolling reserve.

Working out what you actually paid

The single figure that lets you compare one month with another, or one provider with another, is the effective rate: add up every fee on the statement, including monthly and one-off fees, and divide by the total card sales for the same period.

For example, a statement showing $40,000 of card sales and $1,400 of total fees gives an effective rate of 3.5%, because 1,400 divided by 40,000 is 0.035. A quoted rate on an offer is not the same thing: the effective rate includes everything the quote leaves out.

Reserves, chargebacks and other holds

Some offers include a reserve: a share of each payout held back for a set period and then released. On the statement it appears as an amount withheld and, later, an amount released. Track both, because a reserve can make your deposits look short even when no fee has changed. Zolution’s guide to rolling reserves explains how they are set and released.

Chargebacks usually appear twice: as the disputed amount taken back, and as a separate chargeback fee. Count the chargebacks and the sales transactions for the same month to follow your own ratio; Zolution’s guide to chargeback fees and ratios explains how the card networks measure it.

Your statements in a new application

If you have processed cards before, recent processing statements are one of the documents a provider may ask for. In Zolution you keep your documents in your own storage and add a private link for each one under a type such as bank statements or processing statements; you choose which links to release at application review, and the provider can ask for more in the application conversation.

Statements show a provider your actual history: volume, refunds, chargebacks and any reserve already held. What it concludes from them is the provider’s decision. If part of your history is missing, add a missing-history note rather than leaving a gap unexplained.

Questions to ask a provider about its statements

• Will interchange and network fees be shown as separate lines, or only as one combined rate?
• Which monthly, annual and one-off fees can appear, and under what names?
• How are chargebacks, chargeback fees and reserve withholdings and releases shown?
• Are fees taken daily from each payout or once a month, and on which date?
• Can I download statements and transaction-level reports, and for how many past months?
