Hi there, @Rich428.
When previously cleared and reconciled transactions were voided, deleted, or modified some transactions may get unreconciled which affects your balance. Also, you can get the same result if the data file is damaged or corrupted. Let's get this sorted out.
To fix the incorrect ending balance, let's start with running the Reconcile Discrepancy report. Use this report to identify the transaction causing the discrepancy.
Here's how:
- Go to the Reports menu.
- Select Banking from the drop-down list then selects Reconciliation Discrepancy.
- Choose the appropriate Account, then select OK.
- If you find a discrepancy, note the transaction date and the Entered/Last Modified, which will tell you when the change occurred.
If the transactions show they were changed, you'll need to make the necessary corrections. For further assistance, I suggest consulting your accountant. If you have to add entries or you have modified previously reconciled transactions, you can perform a mini-reconciliation. Before doing so, make sure to create a backup of your company file to avoid data loss.
However, if you find no discrepancy in the report, I recommend following the solutions outlined in this article for possible data damage: Fix your QuickBooks Desktop company file.
