Audit trail
QuickBooks’ built-in, unalterable log of every change made to the company file — who entered, edited, or deleted each transaction, what changed, and when — so nothing in the books is anonymous or untraceable.
What audit trail means.
The audit trail is QuickBooks’ built-in record of every change made to the company file: each time a transaction is entered, edited, or deleted, QuickBooks logs who did it, when, and what the values were before and after. It is maintained automatically and cannot be turned off or altered by users, which is what makes it trustworthy as a record.
In QuickBooks Online it is the Audit Log; in QuickBooks Desktop it is the Audit Trail report. Same idea in both: a complete, time-stamped history of activity in the file, attributed to the user who performed each action.
Why the audit trail matters.
The audit trail is accountability built into the books. When a balance changes unexpectedly, an invoice that was there last week is gone, or a number doesn’t match what someone remembers, the log answers exactly what happened, when, and who did it — turning a mystery into a fact. That makes it indispensable for catching errors, investigating discrepancies, and detecting tampering or fraud.
It is also a core tool in forensic and cleanup work. Before a file can be trusted, you often need to know how it got into its current state — the audit trail shows the deletions and after-the-fact edits that explain why the books drifted, so the corrections fix the real cause rather than the symptom.
Nothing in a QuickBooks file is truly anonymous. The audit trail remembers who entered it, who changed it, and exactly when — even after the transaction itself is gone.
How audit trail works.
The audit trail records automatically — there’s nothing to switch on. To use it, you open the Audit Log (QBO) or run the Audit Trail report (Desktop) and filter by user, date, or transaction to see the full before-and-after history of what changed. The value isn’t in producing the log; it’s in reading it to reconstruct what actually happened in the file.
Numbers changed and no one knows how?
A QuickBooks ProAdvisor reads the audit trail, finds what changed and when, and scopes the correction in writing — fixed-fee.
