Since 1902 Release, it’s possible to plan the units other than time in the work package of the project. In Plan Customer Projects app, in the work packages tab, you can add a “unit based” work package, and select a unit previously assigned to a resource.
However, if you want to plan a time-based work package, there is no other unit that “Hours”:
I have to plan and bill some customer projects in days.
Did you already face this requirement?
What is the best practice in this case?
Thanks for your help ;-)
