Definition: Time / case management (in e-conomic also known as the Project) is a tool to manage consumption of hours and materials for companies that live by selling services, perhaps combined with goods.
Once the company has registered all hours on a case or project, these records provide a basis for billing for time spent and materials consumed.
It allows you to see if there is over-or under-coverage of each case / project, which in turn enables the company to become better by choosing the cases / projects that are profitable, and avoid those that produce losses.
Registration of billable time also gives an overview of how much the company may be invoiced in future periods, which may contribute to better financial management.
Electronic time / case management also allows to get statistics on how much of an employee's time can be billed and how much of the time elapsed, there is internal and thus not billable time.
