Ticket orders get fulfilled against the ticketing platform, on their own
Selling through a channel of your own while keeping the ticketing platform as the system of record means somebody has to copy bookings from one to the other. That somebody makes mistakes, and they make them on a Saturday.
Now the order fulfils itself: the booking gets created in Xceed with its tickets and its extras, and if something cannot be reflected — an extra that does not exist there — it gets noted on the booking rather than lost. A declared failure gets fixed; a silent one gets discovered at the door.
Xceed is today the only integration we have confirmed, and that is why it is the only one we name.
