You can set whether employees can enter overtime and have it immediately credited to the overtime account, or whether overtime entries must first be approved by a supervisor.
You can also configure other absence types to require approval or not, for example for working from home or business trips. So to set overtime as requiring approval, follow the same procedure as for all other absence types. Read here how to [set overtime as requiring approval(/absence-management/settings/approval-requirement-for-absences/).
Not applicable to time tracking
Please note that the approval requirement for overtime described here applies only to the [overtime feature(/time-tracking/features/time-tracking-or-overtime-feature/), not to the [time tracking feature(/time-tracking/features/time-tracking-or-overtime-feature/). In the time tracking feature, employees enter their working hours in full, and Timebutler calculates overtime automatically, so employees do not enter separate overtime entries.
