Ineed to UNDO a reconcilliation and do not have an accountant???

Welcome to the Community, @venuemode.

Since you don't have an accountant to undo the entire reconciliation, you'll need to manually unreconciled each transaction. Let me guide you through the steps.

1. Click the Gear icon, then select Chart of Accounts.
2. Find the appropriate bank, then click View register.
3. Select the transaction to edit.
4. Under the Check column, click the box repeatedly to change the status. ("C" - Cleared, "R" - Reconciled, and "Blank" - Not cleared or reconciled)
5. Click Save.

Here's an article you can read for more details: Undo and remove transactions from reconciliations in QuickBooks Online.

Keep in touch if you need any more assistance with this, or there's something else I can do for you. I've got your back. Have a good day and keep safe.

Dear Mark,

Can I undo ALL reconcilliations from the beginning? 

Thank you

Hi there, RecCons.

Thank you for visiting the QuickBooks Community. I’d be glad to assist you with unreconciling all previous statements process so they will not throw off your records.

Yes, you can undo all reconciliations from the beginning. Please note that removing the transactions from the reconciled period might affect your beginning and ending balance on the previous and future reconciliations. I recommend reaching out to an accountant to help you identify the best way on how to delete previous bank reconciliations.

Then, if you’re currently using QuickBooks Online Accountant, you can use the Undo a reconciliation feature to unreconciled previous entries without manually editing individual transactions from within the register. To visually guide you through the steps, click on this link: Undo or remove transactions from reconciliations in QuickBooks Online.

However, if you're using the regular version, you'll have to manually remove the R (Reconciled) under the Check column to undo a reconciliation via the register. You can follow the steps shared above on how to perform the process.

Once done, start the reconciliation process again by following the instructions or details provided in this article: Reconcile your accounts. This also provides different guidelines that will help you fix any reconciliation errors.

Please let me know if you need additional help in reconciling your account or any QuickBooks concerns. I'm always here to help. Have a great day ahead.
