Atelier Software has released <A HREF="http://www.fanuriotimetracking.com/">Fanurio, a Windows time tracking and billing application</A> designed for freelancers. With Fanurio you can easily organize your work, track time and create invoices.

In order to keep track of client work, you can create a project for each client. Then you can record time and expenses. Work can be marked as billable or non-billable using a flat rate or an hourly rate.

The application can be accessed from the Windows tray bar and it detects idle time. Fanurio can export its data to a CSV or Excel file so that you can easily import it in other applications like Microsoft Excel or OpenOffice.org Calc.
