Look no further, @cmoulton.

The option to add the time activity of your employee on the invoice is currently unavailable. As a workaround, you can run the Time cost by employee report and send it to your employee so they can see the details. Here's how:

1. Go to the Projects menu.
2. Select the project to which the employee is assigned. Example: Project 1.
3. Click the Hourly Time Cost option.
4. You'll be routed on the Time cost by employee report for your customer's project. 
5. To modify the details on the report, click the Customize button. 
6. Once done, you can click the Print or Export icon so you can send a copy to your employee. 

For your reference, please see this article: How to turn on and set up time tracking.

I also encourage you to visit our QuickBooks Blog website for more product enhancements and updates.
