Cancelling marks the event as no longer taking place. All bookings for the event are cancelled, and Bix emails every attendee to let them know.
Open the event and select Cancel event.
Choose whether to refund attendees as part of cancelling. Refunds need your available balance to cover the full amount - if it can't, add funds first or refund bookings individually later.
Confirm (please note, this cannot be undone).
Cancelling without refunding leaves each booking's payment in place, with a Pending refund flag until it's resolved - you can still refund bookings individually or move customers to another event afterwards.
