Payment Audit

Overview

A payment audit traces how transactions move from initiation through authorization, processing, settlement, refund, dispute, and accounting. It may evaluate financial accuracy, security, compliance, approvals, reconciliation, merchant handling, and provider performance.

Evidence includes system logs, processor statements, bank or blockchain records, invoices, configurations, samples, and control testing. Findings depend on period, systems, data completeness, materiality, and access, so conclusions remain limited to the declared scope.

Audit sampling should include failed, reversed, delayed, and manually adjusted transactions.
