I have forgotten to enter the opening balance and the opening c/f dateTried to edit and change it but system don't allow me to do so. How can I fix it?

There's no need to edit the 'as of date' when adding an account, leeskkh. It's auto-filled.

Once the account has transactions, the option to edit it is not possible. You can delete the transactions associated with that account so you can modify the opening balance. Let me show you how:

1. From the Accounting tab, select Chart of Accounts.
2. Click the Account history drop-down arrow of the account you’d want to modify.
3. Select the transactions and click Delete.
4. Select Yes to confirm the action.
5. Click the Back to Chart of Accounts link at the upper-left part.
6. Select the account, and click the Account history drop-down arrow.
7. Select Edit.
8. Enter the Balance.
9. Click Save and Close.

If you prefer not to delete the transactions, you can create a deposit. Then, subtract the opening balance to the recent QuickBooks balance.

There you have it. Please reach out to me if you still need help.
