Hi DSG1,

Reconciling accounts has never been easier with QuickBooks Online. Well done on successfully reconciling July and August. I'll be happy to share more information about this issue. 

Making edits to amounts on past/reconciled transactions will affect your balances. The next best step from here would be reaching out to your accountant for expert advice. If you're not in contact with one, I encourage you to search for one on our website using this link here. 

If you'd like to edit/undo any reconciled transactions, follow the steps below:

Note: You'll have to undo each individual transaction. If you'd like to un-reconcile in bulk, I recommend reaching out to an accountant that uses QuickBooks Online Accountant. 

   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.
