You can set up your Chart of Accounts to show an account number next to each account name.
A complete list of a business's accounts. The accounts that appear on the balance sheet are called “balance sheet accounts.” Other accounts track particular kinds of expenses or income.
This option shows you only the account you are working with when entering transactions.
For example, the expense account on a check would be shortened to:
5411-Main
rather than the full account path:
5400-Rent: 5410-Office: 5411-Main
You do not have to assign account numbers to your Sales Tax Payable or Undeposited Funds accounts. QuickBooks assigns numbers to these accounts automatically.
