When entering an invoice can you split the invoice into different classes

It's nice to see you here, @Alice24.

Yes, class tracking is available in QB Enterprise. I'd love to guide you in setting this up.

Class tracking helps you to track your items or transactions easily. You'll first need to turn on this feature before using it. Please follow these steps:

1. Click on Edit from the menu bar.
2. Choose Preferences. 
3. Click on Accounting.
4. Select the Company Preferences tab.
5. Tick the Use class tracking for transactions.
6. Under the Assign classes to drop-down, choose where you want to assign classes. 
7. Click on OK.

Once done, you'll now be able to assign classes depending on which items or transactions you want to track. 

Also, you can add classes by going to the Class List. Let me show you how:

1. Click on Lists from the menu bar.
2. Select Class List. 
3. Under the Class drop-down, click on New.
4. Enter the Class Name. If the class you're adding is a subclass, tick on the Subclass of checkbox.
5. Click on OK.

That should do it. Fill me in if you have other concerns by leaving a comment below. I'll be sure to get back to you. Have a good one!
