The QuickBooks Audit Trail (or Audit Log, depending on the version) provides a log of each accounting transaction and denotes any additions, deletions or modifications affecting the integrity of the transaction. The tool captures every transaction from the time it is initially entered into QuickBooks, and tracks changes to the original entry, including transaction type, date, account, vendor/customer name, transaction amount, quantity, and price. The Audit Trail also reveals the User ID under which the entry, deletion or modification was made. The Audit Trail is a report built in the QuickBooks ReportCenter– all you have to do is click a button to generate the report.
