Pricing tiers
Set as many paid tiers as the night needs. Each one has a name, a price, and optional capacity — guests mix them in one cart.
GA, VIP, early bird
Named tiers with a price, a slot count, and a date range when each one is on sale.
Mix them in one cart
Guests can take two GA and a VIP in the same checkout. Inventory is held while they pay.
Sold out stays sold out
Capacity and sale windows are checked at checkout, not just in the UI.

Per tier
Name and price
GA, VIP, early bird — as many paid tiers as the night needs. Guests can mix those paid tiers in one cart.
Sale window
Each tier has a sales start and a sales end, in the event's timezone. Outside that range it is not for sale, even if slots remain.
Slots
Set a quantity and the tier stops when those slots are gone. Leave the quantity blank and it stays open until the window ends.
