The door
Selling the night, then getting people into it.
Tickets sell online and at the venue, and what has gone is worth watching before you commit to how many staff you bring in. At entry a ticket is checked and then spent: presented a second time it does not open the door again. Where parts of a night are not open to everyone, wristbands carry the access level, so the only place anyone has to think about it is the door. Ticket types, prices and the seating plan are set on the event itself.
The bar, and what the night was worth
Why an event is easier to close than it is to run.
Once people are in, the bar works the way it does on an ordinary evening: the same tabs, the same tills, the same staff roles. The difference shows at closing rather than during service. Ticket revenue, bar takings and the door count settle into the reports the venue already reads each week, so nobody has to treat the event as a special case to find out what it made. Where a venue also sells online places beside the seats in the room, RoomHex handles those and they land against the same event.
