Yes, you're right, @East Regiment Beer Co.

As of now, the option to assign classes to your expense and income accounts is only available in QuickBooks Enterprise. For more info about it, please check out this article: Set up and use class tracking in QuickBooks Desktop.

I'll share some steps to get around this. First, you can use the Class column instead and then select the right income or expense account when creating transactions like invoices, bills, etc. This way, you can link the correct class to its corresponding account properly. 

To achieve this, we can perform a few tweaks on the Preferences page. Let me guide you how:

1. Go to Edit, and then select Preferences.
2. Choose Accounting, and then select the Company Preferences tab.
3. Navigate through the Class section, and then make sure to check the Use class tracking for transactions and Prompt to assign classes boxes.
4. Click OK to save the changes.
   

Second, you can add the class name on the account's Description field. You can also set a class if it's a sub-account.

Here's how to do it:

1. Go to Lists, and then Chart of Accounts.
2. Select New from the Account drop-down.
3. Choose Income or Expense as the account type.
4. Indicate the class name on the Description field. You can also use the Subaccount of if the account is a sub-account.
5. Click Save and Close when you're ready.
   

To keep track of them, you can run and customize class-related reports in QuickBooks Desktop. For more details, please review this article: Filter, sort, or total reports by Class.
