How to display employee/worker name per line item in an extra column on invoices?

Thanks for posting your concern, @cinderblock. 

To display an extra column for the employee/worker name in QBDT, customize the invoice template and add the column. Here's how:

1. Go to the List menu and select templates.
2. Choose the template you use on the invoice and double-click to open it.
3. Click Additional Customization, then tap the Column tab.
4. Mark the Other boxes to display on the screen, choose the order of the columns to arrange them in the preferred order, and then label the title (e.g., Employee).
   

    

5. Click Okay. Go to the Invoice window.
6. On the Template drop-down, select the correct template, and you should now be able to see the added column.

I also encourage you to submit a request to our product engineers if you have any additional improvements on the invoice feature to include them in future software updates.

Here's how:

1. From the Help menu, select Send feedback online.
2. Click Product Suggestion in the Product area, and pick Customer & Sales.
3. Enter your request, then the Send Feedback button.
