You can only select one task or activity for each row. Therefore, you must punch in and out for each unique task or activity you work on. If you are working on a single task that will be billed in two different ways (for example, billable and non-billable), you will need to punch in and out for time spent using each type of billing.

Note:
The Punch In button is only available if your last action was punch out. If the Punch In button isn't available, you are likely already punched in.
You may log out of Web TimeSheet while you are punched in – your hours will continue to be recorded, and you can punch out next time you log in.
