Enabling Account Numbers in QuickBooks
By default, QuickBooks does not assign numbers to accounts, and you should switch your QuickBooks configuration options to correct that oversight. A chart of accounts with numbers is easier to design, and easier to work with.
To enable account numbers in QuickBooks choose Edit | Preferences to open the Preferences dialog box. Select the Accounting icon in the left pane and the Company Preferences tab in the right pane. Check the Use Account Numbers option to enable account numbers.
