sales by item detail report filtering a class

Welcome to the Community, @dickinson. I got your back to ensure you'll be able to run a report that will also show the employee's hours in QuickBooks.

Thanks for sharing details about your issue. This really helps me to come up with a solution to resolve it. First off, let me discuss some details on how you can perform the task.

In QuickBooks Desktop (QBDT), sales report such as Sales by Item Detail only shows information related to customers, items, sales reps, pending sales, and sales orders. That's the reason you can only see the data for invoices where a class has been selected. 

That said, you'll want to run a separate report to view your employee hours and the class assigned to them. To do so, access the Time by Job Detail report. Here's how:

1. 1. In your QBDT, go to the Reports menu.
   2. From there, highlight the Jobs, Time & Mileage field.
   3. Next, choose Time by Job Detail.
   4. Then, select the Customize Report button.
   5. In the Column section, check the Class option and click OK.
   6. Once done, select the Refresh button (see screenshot below for visual reference).

For more information about the data displayed in various reports in your program, feel free to check out this article: Understand reports.

Additionally, here’s an awesome resource you can access to help you memorize the changes made to a report: Create, access and modify memorized reports.

If you have further concerns about running class reports in QBDT, don't hesitate to post again here. I'd also appreciate any updates on how the steps go. Please know that I'm always ready to lend a hand to ensure your goal is achieved. Have a great week ahead.

RE: The timesheets where we added the specific class, the invoice and labor had already been invoiced prior so we are going back to the timesheet and adding the class after it has already been imported to the invoice via the 'add time/costs' button'. I'm thinking maybe that might have something to do with it.

Yes, when you update time records after they're invoiced, the invoices aren't changed.

However, you can go back to the invoices and add the desired classes to invoice line items, both the time and most any other items, except items like subtotals which don't appear on reports in any case.
