Price tiers, who sold what, walk-ups, and how tickets become the door figure.
On a ticketed night the door figure is not typed in — it is the sum of the ticket lines you record, recalculated every time one of them changes. That keeps the number a revenue split is worked out from tied to something you can point at.
Set up whatever tiers the room actually sells — general admission, VIP, early bird, whatever you use. Each carries its own price, and you can see how a night broke down across them.
Walk-ups are a channel like any other, which is what makes someone who turned up on the night count toward the door exactly like someone who bought a fortnight ahead.
Only tickets sold by the act are credited to that act. A walk-up was brought by nobody in particular, and crediting it would inflate a draw figure that exists precisely so it can be trusted.
The ticket count and the headcount you record are rarely equal — tickets get bought and not used, comps walk in without one. The difference is shown rather than quietly reconciled, because which of the two is wrong is a judgement only the person who worked the door can make.
A no-cover night or a private hire sells no admission, so it has no ticket lines and no computed door. Trying to record tickets against one is refused rather than quietly stored.
While a ticketed night is booked and not yet settled, its page also shows where the advance sales are against your own comparable nights at the same point. It needs three comparable nights on record before it will call a pace at all — see break-even and how a show is selling.
