Artologik Time is a Web-based tool that offers a very simple way of recording time worked in both external and internal projects. Time provides you with a quick overview of the amount of time spent in on-going projects. If you are a project leader you can also view what the users have been doing and when. The information can be used to generate tenders, invoices, and invoice details. This is a Web-based program that has to be installed on a Web server.
