Overtime or time item types were added to timesheets to support premium rates payments and billing rates. Overtime types are associated with the timesheet type and in turn with a work-schedule, and allow clients to define for example 1.5x pay and billing rates for certain projects, work conditions or work-hours. You can choose whether employees select the overtime type manually in their timesheet or calculate this automatically using our future time evaluation module. You can also limit the number of overtime types selectable in timesheets to ones defined in the employee compensation details (as opposed to create separate work-schedules and timesheet types for each unique employee group)
