Classes for Activity-Based Costing in QuickBooks 2014
Set up your classes.
You set up a class for each product or service for which you want to measure profitability. In an imaginary hot dog stand business, for example, you set up two classes: one for regular hot dogs and one for chili dogs.
To set up a class, you can just enter the class name in the class box that appears in the window that you use to record invoices, write checks, and make journal entries. Alternatively, you can choose Lists→Class List.
When QuickBooks displays the Class List window, click the Class button shown at the bottom of the window, and choose New from the menu that QuickBooks displays. Use the New Class window that appears to describe the new class.
