Payment processing guides for merchants.

Plain-English explainers for statement audits, processor-specific reviews, interchange, card network mandates, industry fee patterns, and payment cost reduction. Each guide links back to the StatementIQ upload workflow when you are ready to review a real statement.

Start with the question closest to yours.

These pages are intentionally practical: what the topic means, which fields matter, and how a merchant can turn the statement into a processor conversation.

Statement reviews

Start here when you have a merchant statement and want to understand what the file says.

Processor-specific reviews

Use these when the processor name on the statement changes the questions you should ask.

Industry fee guides

Restaurant and retail merchants often have different transaction patterns, fee labels, and operating constraints.

Network rules and pass-through cost

Understand interchange, card mandates, and the parts of processing cost that may be pass-through versus controllable.

Want a review of your own statement?

Upload a recent merchant processing statement and StatementIQ will show whether there is enough evidence for a useful report.
