Hello, @lknox.
There are lots of possible reasons that cause beginning issues for the reconciliation in QuickBooks Online. It could be that someone edited, deleted, moved, or unreconciled a transaction that was on a previous reconciliation. Or, someone manually reconciled a transaction. To fix the problem, you can start by reviewing any discrepancy reports.
- From the Reconcile an account window, select We can help you fix it link.
- Review the discrepancy report. Before editing any of the transactions on it, talk with whoever made the changes - they may be intentional.
- Once you know you can make corrections, edit each transaction on the report one at a time.
- Select View to see the history of changes to the transaction.
- Review the Change Type column. This tells you what changed.
- When you're ready to make edits, select the transaction to expand the view.
- Make edits based on the message in the Change Type column:
- Amount changed
- Unreconciled register
- Reconciled in error
- Deleted
For the detailed instructions, open this article and go to the Step 4: Review any discrepancy reports section.
