QB Issue Resolution:

If you haven’t completed the reconciliation, you can still edit the statement ending date by following these steps:

  1. On the left panel, click Accounting.
  2. Click the Reconcile tab.
  3. Choose the bank account from the Account drop-down list.
  4. Click the Resume reconciling button.
  5. Click the Edit Info button located in the upper right-hand corner.
  6. Change the Ending Balance and Ending Date.
  7. Click Save.

If it’s finished, changing the Ending date is unavailable. Though, you can do either of the following:

  • Leave the date as it is and just make sure to select the correct end date the next time you reconcile (an incorrect date doesn’t affect any balances and will not prevent you from future reconciliation).
  • You can undo the reconciliation and then reconcile with the correct ending date.
