Is there any documentation on how the process of invoicing from timesheets? Today I use products to bill the hours that I work to the customer, but it seems it should be possible for me to enter my timesheet details in OpenERP and invoice from that.
Let's say I have two customers: Customer A and Customer B. For each of these I work on one project, Project A and Project B. Project A is an easy one, not so large, but project B is divided into four activities, which the customer would like to have the hours billed to, for example Analysis, Development and Support.
Should I use the project module for this? It doesn't seem to be possible to register hours in the timesheet for activities, so should I make projects for both the projects and the activities?
