Bank reconciliation is a critical accounting task that ensures your financial records in QuickBooks match your bank or credit card statements. However, mistakes can happen—such as reconciling the wrong transactions, using an incorrect ending balance, or discovering errors after the reconciliation is completed.
In such cases, accountants often need to undo or unreconcile transactions in QuickBooks Online (QBO) or QuickBooks Desktop. This guide explains when, why, and how to undo reconciliation safely, while maintaining accurate books and audit compliance for U.S. businesses.
What Does Undo Reconciliation Mean in QuickBooks?Undoing reconciliation in QuickBooks means reversing the reconciliation status of transactions so they can be corrected and reconciled again properly. When a transaction is reconciled, it is marked with an “R” in the register and locked into the reconciliation report.
