No, you don't have to hire an Accountant. You can remove the "R" for reconciled within the account register of the account you need to re-reconcile. If there are "many" transactions in the register and it would take a long time to do this, you can use a different email account to create a "QBOA" (QuickBooks Online Accountant) account, then send yourself an Accountant invitation. Once accepted, you can act as your own Accountant and "Batch Undo" the account reconciliations under the briefcase icon (Accountant Tools/Reconcile/History by account/Action/Batch Undo) for Accountants in the QBOA account login.
Ps: Also, I am an Accountant, and I do not charge my clients to "Undo" account reconciliations for them when they choose to do their own account reconciliations and need to redo them.
Log back into your regular QBO account and send yourself an Accountant invitation to the email address you used for your QBOA (Firm) account. Then go to that email account and accept the invitation. Then login to your QBOA account and go to your client list, you should be there as a client (Your Practice/Clients). Select your regular QBO client. Then go to "Reports" and "Reconciliation Reports", this will take you to the same screen as the Accountant Toolbox method.
Just creating the Accountant login (QBOA firm account) is not enough. You have to invite yourself as an Accountant under your original QBO account so you can access that account as the Accountant under the firm account. Make sense?
I am trying to undo a batch for my reconciliation from Feb. 2020 to fix a transaction QB duplicated. If I do this it will undo all my 13 reconciliation.
This is what happened: We received an payment through QB but the payment was rejected. QB and our bank received this payment, and then it was debited. We had to resent the invoice to our client, he paid and the payment was received without any problem. Now, we have the 1st payment payment on our client account but because it was not applied to any invoice, only registered in account receivable, our invoices and account receivable do not match. Is there a way to fix this? Any help will help.
As of the moment, the feature to undo an entire reconciliation is only available for all Accountant users using the QuickBooks Online Accountant account.
