Yes. You can block off scheduled events on your calendars as “non billable”. As Kitchen Administrator, you are able to create events on your own calendars.
To get started, go to the Scheduling Tab and do the following:
Create a new event by dragging and dropping on the day/time frame you need.
Select 'N/A (non billable)' for the Client.
Enter Booking title and select space.
If it is a repeat booking, choose how the booking will recur.
Add any notes (optional)
Click 'Create Booking.'
Note: If you are closing the kitchen entirely for cleaning or an event, you will need to create a separate non-billable event on each of your kitchen's space calendars.
