Admins and managers (who have timesheet permissions enabled) can add and edit timesheet records on the Attendance page.
Timesheets are interactive, so you can manually correct a clock in time, add an 'out 'time if the employee has forgotten to do so, or add a new record completely.
You can create a clocking in record from a shift on the rota by clicking the green plus icon when shifts are displayed on the timesheets.
If you want employees to be able to manually edit their own timesheets, you can enable this option under Settings → Time and Attendance.
Any timesheet record added by an employee requires admin or manager approval.
To approve a timesheet, click on the employee's name in the Attendance section to view their timesheet, and click the Approve button at the top of the page.
