The documentation says:
"Don't create a Project for each of your customers - this will be too complicated to manage properly."
Why?
I work as a freelancer, and I'm looking for a way to track time invested in each client. Each client could have more than one project, so I always have that hierarchy: client -> projects -> tasks.
Why is it not recomended to create a project per customer/client? How can I track the tasks if I don't create a project?
