Good day, Noel. I appreciate all the details you've shared about your concern with the beginning balance.
This error message will show up if there are changes made to transactions that are already reconciled. For instance, if someone edited, deleted, moved, or unreconciled them. Doing so would change the ending balance of the previous reconciliation, thereby affecting the beginning balance of the subsequent one.
There are also a couple of steps that we recommend to resolve the issue.
You can start by reviewing the opening balance. It's the starting point for accounts in QuickBooks. If it’s incorrect, it affects all future reconciliations.
Next, if your account is connected to online banking, make sure to match and categorise all of your downloaded transactions before reconciling to ensure the correct beginning balance.
Depending on what's causing the error, you need to make the necessary adjustments to remove the discrepancy.
