It's good to have you here, @rnapol02.

Allow me to share some information on how class tracking works in QuickBooks.

With QuickBooks Desktop, you will be able to track your income and expenses by department, location, property, project or event. You can also assign classes to each of your transactions and items listed in your estimates, invoices and sales receipt.

However, if you're using QuickBooks Desktop Enterprise you'll have the ability to set up and assign classes to your customers. Here's how:

1. Set up class for names
   1. Go to Edit.
   2. Choose Preferences.
   3. Select Accounting.
   4. Under Company Preferences, put a check mark on Assign classes to.
   5. Choose Nameson the selection.  
2. Assign classes to your customer
   1. Click the Customer menu.
   2. Select Customer Center.
   3. Look for the specific customer.
   4. Double-click to open customer information.
   5. Choose Additional Info.
   6. Click the Classes drop-down selection.
   7. Assign a specific class to the customer.  

That should do it! Repeat the same steps to assign classes to all of your customers.
