How do you add a customer account number in Mac Quickbooks desktop?

I'm here to guide you on how you can set up account numbers for your customers, Scooter27.

QuickBooks adds accounts automatically to your chart of accounts that fit your business type. You'll want to make sure to set up the account number for each of your customers' account names. I've outlined the steps below that will show you how:

1. Go to the QuickBooks menu, then select Preferences.
2. Select Transactions, then select the Use account numbers checkbox.
3. If you have subaccounts, select the Show lowest subaccount only checkbox to shorten the account details when you use them in your transactions.

Once done, add account numbers to existing ones if you've already previously set them up, you can follow the steps below: 

1. Go to the Lists menu, then select Chart of Accounts.
2. Select the account you want to edit, then select the 📝 icon.
3. In the Number field, enter the number of the account.
   Note: QuickBooks automatically assigns account numbers to your Sales Tax Payable or Undeposited Funds accounts.
4. Select OK.
