Fill in the details of the timesheet. The required fields are marked with a red asterisk. Add new clients, projects and tasks on an ad-hoc basis by clicking on the green plus icon beside each drop-down box.
The timesheet can either be marked as billed or unbilled. If the timesheet is marked as unbilled, the timesheet can be converted into a draft invoice from the Tools > Time tracking > Generate invoice menu once completed.
Click on the Save button to complete.
