This is a ready to be used demo version of I.V.S. You can calculate and organize projects during a certain period of time. We used to have the problem that by the end of a month we did not have an overview of the "performance" of our employees. That made it difficult for us to calculate. I.V.S is thought for companies, independent professionals and all others.
Input of hours-of-work is achieved as follows: Customer <-> Project <-> Hours-of-work
The licensed version offers multiple customers, projects (customer-specific) and tasks.
With the supplied demo version you do not have the builtin user-administration; therefore everybody is able to see the data of the others! This isn't true with the full licensed version.
