How to review merchant processing fees on a monthly statement

Start with the processing statement, transaction export, settlement report, and bank deposits for the same merchant account. Identify the currency, entity, period, and date basis used by each file. A statement based on processing dates will not automatically match deposits received during the same calendar month. Explain the difference before deciding that the provider withheld an unexplained amount.

Use the settlement trail to separate charges from other movements. Stripe's payout reconciliation documentation and Adyen's settlement reconciliation guidance describe reporting approaches for connecting activity with payouts. Ask your provider for equivalent evidence. A refund, reserve movement, or chargeback principal can reduce a deposit without being the processor's fee for handling a payment.

Build a schedule of each charge, its amount, calculation basis, and statement reference. Distinguish volume-based processing charges, per-transaction charges, monthly service costs, currency conversion, payout costs, dispute fees, and optional products where they appear in your agreement. The categories should follow the actual statement; do not invent a standard fee line that this provider does not charge.

Ask the provider to explain unfamiliar labels and match them to the contract. Under some arrangements, several components are combined into one advertised rate; under others, they appear separately. The useful comparison is the amount your transaction mix produces under the full agreement. A low headline percentage can coexist with fixed costs or scope differences that change the annual total.

Choose a consistent measure for a first comparison, such as selected processing costs divided by the corresponding gross processed sales. State exactly which costs and transaction types are included. If you also calculate a broader rate including software or equipment costs, label it separately. Two percentages are not comparable when one includes monthly services and the other excludes them.

For an illustration, $1,500 of defined processing costs divided by $50,000 of corresponding processed sales equals 3 percent. Adding $200 of separate monthly software cost gives a broader cost ratio of 3.4 percent on that same sales base. These are example calculations, not market benchmarks. Neither measure explains refunds, card mix, international activity, or fixed charges on its own, so retain the supporting breakdown.

Check average payment size, payment methods, customer geography, currencies, refunds, and transaction counts. A per-transaction charge weighs more heavily when average order value falls. A change in cross-border activity may change the fee total even when the provider's contractual rate has not changed. Compare like populations before treating a higher effective rate as a pricing error.

Give prospective providers an anonymized, representative transaction summary and ask each to calculate a written quote from it. Include the additional services your operation needs and any costs of migration or hardware. Ask which assumptions could change the quote after underwriting. Do not let a proposal based on domestic transactions stand in for the cost of a business with substantial international sales.

Trace an unexpected charge to its statement line, contract term, and affected transactions. Ask whether it is recurring, one-time, or a correction, and request the effective date of any price change. Keep the provider's explanation with the statement so the next reviewer does not reopen the same question. For a disputed amount, record the case reference and any credit actually issued.

Review missing deposits separately from excess fees. Stripe's payout documentation distinguishes payout schedules from settlement timing; the same separation is useful when checking another provider's own rules. A delayed payout affects cash availability even if all processing charges are correct. Conversely, an on-time deposit can contain an incorrect fee. Give each issue its own evidence and resolution task.

Finish with the charges explained, unresolved items assigned, and the cost drivers identified. A useful negotiation might ask about a recurring fee for a feature the company no longer uses, a different pricing structure for its transaction mix, or the reporting needed to reduce reconciliation work. Use the actual figures from your review rather than claiming every merchant should achieve one universal rate.

Before switching, compare expected savings with implementation effort, contract terms, settlement arrangements, refund handling, and access to historical records. Keep the old account's reporting available for outstanding disputes and later adjustments under the agreement. Review the first statements after any change against the written quote. The decision is complete when the business can explain both what it pays and what operational work that price covers.
