I dont see any way to undo reconciliation in QB online. In my reconcile history I see the action button as empty in accountant view or business view. Thanks

You made the right choice in reaching out to us, ahmeha-yahoo-.

In QuickBooks Online (QBO), you can undo the reconciliation to delete or zero out the beginning balance. This can be done by manually edit the transactions within the register.

Since the you see an empty option from the Accountant view or business view, let's try isolate this behavior by performing some basic troubleshooting steps. We can start by using a private browser or incognito when performing the tasks. Here are some keyboard shortcuts that you can follow:

• For Google Chrome browser: Ctrl + Shift + N
• For Mozilla Firefox browser: Ctrl + Shift + P
• For Safari browser: Command + Option + P

Once done, you can try manually edit the transaction to undo reconciliation. I'll show you the steps below:
 

1. Go to the Accounting menu. Then select Chart of Accounts.
2. Find the account and select Account history or View register.
3. Select the transaction you want to unreconciled.
4. Click the box with "R" and keep clicking it until the box is blank. This removes the transaction from the reconciliation.
5. Select Save.

If it works, you'd want to clear the cache of your regular browser to delete those temporarily stored files and browsing history. Also, you can use other supported, up-to-date browsers to roll out the possibility of a browser-related issue.
