Hi there, @Accting4SmallBiz. I appreciate you joining the thread. Let me give you additional information to resolve your concern.
 

Time tracking users can only enter their timesheets, and the only access they have is to see timesheets and time reports. But, if you want your employees to manage clients, you can add them as Team. Then, they should be able to access the client's profile.

You might also check the other suggestions and the provided answer above.
 

You can check this article on how to turn on and set up time tracking in QuickBooks Online.
 

Please keep me posted if you need further assistance. I am just around always willing to give you a hand. Have a good one!
