Is there a report available that will include the 'Customer/Project' and 'Class' fields as entered in the "Bill" function?

Welcome to the Community page, usernellagrace328. 

I can walk you through the steps on running reports that will show you Customer/Project and Class in QuickBooks Online.

Here's how:

1. On the left panel click Reports.

2. Enter and select Transaction Details by Account in the Find report by name search box. 

3. Click Customize.

4. Under Row/columns click on Change Columns and tick Class.

5. Under Filter select Customer.
