By default on QuickBooks the account numbers option is disabled. You may have been saying, "help, I can't enter the account number." If you are an effective bookkeeper or accountant you need to label your accounts by number.
Here is how to turn on this option.First, on the menu strip go to the
Edit tab and select
Preferences.

Next, click on the
Accounting tab in the right pane. Select the
Company Preferences tab in the center pane. Check the
Use account numbers check box.

Finally, you can enter an account number for each account.
