How do I change the hours that I logged?

To edit timesheet entries go to, Time & Projects ➝ Time Tracking ➝ click on the pencil icon on the timesheet grid.

You can change the project, task, notes and hours of the timesheet entry.

Note: You can see when the time entry was created and edited if you hover the mouse over the user image in the timesheets table:

I cannot update my timesheet entry. Why?

If timesheet hours have been billed (invoiced) or paid you will no longer be able to edit them on the timesheet grid.

In this case, you will first need to delete the invoice with your billed hours, changing the status of timesheet entry to ‘unbilled’
Now you will be able to edit or delete these hours.
