Merchant Processing Fee Audit

Merchant processing fee audit against your processor agreement.

AllCaps audits merchant processing statements against your processor agreement and pricing schedule to find markups and fees that do not match what you negotiated. Each finding shows the statement line, the contract term, and the calculation.

Typical leakage

Where the money goes

Processing statements combine network costs and processor charges, which makes contract drift hard to see.

Markup above contract

Basis-point or per-transaction markups billed above the rates in the pricing schedule.

Fees not in the agreement

Monthly, compliance, statement, or program fees that the agreement does not list or that exceed its caps.

Unnotified pricing changes

Rate or fee increases applied without the notice the agreement requires.

Pass-through items with added margin

Costs the agreement treats as pass-through that arrive with a markup.

Tiers not applied

Volume-based pricing that should have stepped down once processing volume crossed a threshold.

Charges after a service ended

Gateway, terminal, or add-on fees that continue after the service was cancelled.

Evidence

What the audit checks

The audit uses your agreement and the statements your processor already sends.

Processor agreement

The merchant agreement, its pricing schedule, and any amendments.

Merchant statements

Monthly statements with fee and volume detail, as PDFs or exports.

Change notices

Example

What a finding looks like

A finding separates what the agreement allows from what the statement charged.

Common questions

Frequently asked questions

How do I check if my payment processor is overcharging me?

Compare each fee on your merchant statement with the rates, caps, and fee list in your processor agreement and pricing schedule. AllCaps does this line by line and shows the contract term behind every exception.

Can AllCaps reduce interchange?

Interchange is set by the card networks, so an audit does not change it. AllCaps focuses on what your agreement governs, such as processor markups, fees, and whether pass-through costs were passed through as agreed.

What do we need to send?

Your processor agreement with its pricing schedule and any amendments, plus historical merchant statements. No integration is required for the Proof Audit.

Does this replace our payment processor or reconciliation tool?

No. AllCaps is a contract-level audit layer that works alongside your processor and reconciliation tools.

Will AllCaps contact our payment processor?

Not without your approval. Findings come with contract and clause support so your team can review them first, and any external action remains subject to your approval.

How is a merchant fee audit priced?

The Proof Audit is a one-time fee scoped and priced to your contracts and statements. Ongoing audit is a subscription based on contract and invoice volume.

Start with your own contracts and invoices.

Send up to three contracts and 100 historical invoices. Review evidence-backed findings, then decide what comes next.
