If an account's beginning balance is not set at the time of the account's creation, there is a time period where this amount can be edited.
However, once the account has transactions attributed to it and those transactions are reconciled, the beginning balance is locked and cannot be edited.
To change an account's beginning date or balance,
- Navigate to the Chart of Accounts view and find the account you want to edit.
- To the right of the account name, click the pencil icon to open the edit window.
- Under Opening balance, enter the new beginning date and balance for the account.
- Click "Save" to confirm your changes.
If an account's beginning balance can't be edited for any reason, you will need to use a journal entry to set or correct the initial balance.
