You can track time across different jobs or projects using the department transfer feature. Start by creating a new department for each job or project that you'd like to track. Then assign your employees to the jobs/projects that they have access to, by using the "Department Membership" button that can be found in the employee details screen.

When employees punch in, the TimeStation App will present them with this menu to select a job/project for their shift.
Please note that employees can have a different hourly rate for each job/project which can help you streamline job costing.
