When a period has been invoiced you lock it, so that nobody changes the time afterwards.
How to lock
Owners and admins can do it in two ways:
- Settings → Period lock: choose Locked up to and including.
- Lock the period in the report. The button never moves a lock backwards.
What the lock stops
Days up to and including the lock date can't be changed, not even by owners and admins. That covers:
- the time sheet and the Chrome extension
- Change the time and Replace in the time sheet
- import: rows in the period are left out, and an import with time there can't be undone
- recalculation: locked days are skipped
Which days are locked is worked out in the company's time zone.
Open a period again
Under Settings → Period lock you can set an earlier date or empty the field. The change shows in the change log.
