The question is usually put the wrong way round. Ticketing and guest lists are not two products you choose between — they solve different problems, and most venues need both at different points of the same night.
The dividing line is simple: who pays, and when?
Ticketing: money before the night
A ticket is a transaction up front. The guest pays, gets a claim, and you have the money before anyone is standing outside. That brings two things a guest list cannot: planning certainty and a far lower no-show rate, because a paid-for spot does not get ignored.
The cost is friction. Every step between "interested" and "paid" loses you guests, and on free or last-minute nights it loses you more than the money is worth.
Guest list: access rather than revenue
A guest list does not govern who pays, it governs who gets in. It is the instrument for everything not controlled by price: promoter allocations, press, artist guests, regulars, partnerships.
Its strength is the low barrier — a link, a name, done. Its weakness is the same property: what costs nothing also gets forgotten. Twenty to forty percent no-shows is normal, as covered in cutting the no-show rate.
The decision as a table
| If … | then … |
|---|---|
| entry costs money and you need to plan | ticketing |
| promoters get allocations | guest list |
| the night is free but capacity is managed | guest list |
| press, crew and artist guests come in | guest list |
| you separate advance sales from the door | both |
The mistake that actually hurts
Not picking the wrong one — running two separate systems on one door. If ticket holders live in one app and guest list spots in another, your door checks two sources per person. That doubles the time per guest and makes the capacity maths from door planning worthless, because nobody holds a live count any more.
What matters is not whether you use ticketing or a guest list, but that both resolve into one check at the door.
EventSync is the guest list and door side of that: one scan per guest, regardless of which route put them on the list.
