Inhouse-Web is Web-based time recording and tracking software built for companies that want to track their projects' worktime to get accurate time billing for their customers. In contrast to other time trackers, Inhouse-Web will not offer its own task system.

But this application is quite a bit more than a simple time tracking system. You can also manage your company's stock of software and hardware, books, and other materials.
