Hello dear proffesionals,

Maybe you can help me to find the way to solution :)

My customers are buying document clearing services. It means, they order long term services, pays advance and waits until I make those services. Each service is mentioned in products list. Date of task is important. I want to see progress of all project. At the end I wish to write one invoice and reconcile payments.

How can I manage all process ? Is it right way to use projects in this situation ?
