You can quickly cancel (and credit) most booking types directly from a facility's calendar. Keep in mind payments cannot be refunded via the Calendar subtab and admins need to have the Invoicing permission enabled to cancel a booking with an invoice.
How to Quick Cancel
Via the Facilities>Calendar subtab:
You may filter by booking type to find the booking event and click on it.
Click on the booking's payment status (PAID or UNPAID).
Click Cancel to cancel the booking. NOTE: Click View Invoice if you prefer to view and/or cancel the invoice within the client billing tab.
Once cancelled, the invoice amount is credited in the client's account and the facility becomes available again.
