The Timers feature is used to track the time you spend working on particular tasks. Timers are a part of a project, and each service item of a project can have its own timer, which is used to track work for which you charge by the hour. Bill Engine multiplies the duration of a service item by its billing rate indicated in Inventory to determine its final cost, which is then added to the total cost of the project.
The full list of active timers appears in the Mac OS X menu bar, next to Spotlight, time, sound volume, and other icons. You can start/stop a timer there or in Projects, next to the specific project item whose duration it is tracking.
All active timers switch to the Idle mode after your computer has been inactive for some time. To choose how soon you want the Idle mode to be switched on, go to Bill Engine > Preferences > General.
The readings of all active timers will appear in the menu bar so that you can view, stop, or restart them while working on your various tasks. You can also create a new timer there.
