Audit Trail
A chronological record of all changes and transactions that allows tracing any figure back to its source.
An audit trail is a sequential record that provides documentary evidence of the sequence of activities that have affected a specific operation, procedure, or event. In accounting, it means being able to trace any number in the financial statements back through journal entries to the original source document.
A robust audit trail answers three questions: what happened, who did it, and when. It includes timestamps, user identities, before-and-after values, and references to supporting documents (invoices, receipts, contracts, approvals).
Audit trails are essential for external audits, regulatory compliance, fraud detection, and internal controls. Without them, auditors cannot verify financial statements, and management cannot identify errors or irregularities.
Modern accounting software maintains audit trails automatically, logging every entry, modification, and deletion. The key discipline is ensuring that source documents are retained and linked — a digital audit trail is only as good as the documentation behind it.
