Hi there,
I appreciate you reaching out to the Community for assistance. I have some insight on how to undo a reconciliation which I'll share below.
If you're not working alongside an accountant, you can undo a reconciliation by manually editing each transaction from the register. Follow the steps below to see how you can do this:
1. Select the Gear icon on the Toolbar.
2. Under Your Company, select Chart of Accounts.
3. Locate the appropriate account for the transaction.
4. From the Action column, select Account History.
5. Identify the transaction to edit.
6. In the reconcile status column (indicated by a check mark), repeatedly select the top line of the transaction to change the status of the transaction.
Codes indicate the status of the transaction:
C - Cleared
R - Reconciled
Blank - Not cleared or reconciled
7. Select Save.
For additional tips on how to avoid undoing a reconciliation, take a look at this article: Avoid undoing a reconciliation.
