Creating a guest list takes ten minutes. Creating one that still holds when four hundred people arrive at half past eleven takes the same ten minutes — you just make four decisions up front instead of halfway through the night.

Step 1: Decide who is allowed to add names

This is the decision that saves the most grief later. Three models are common:

If promoters are involved, give each one their own link. Without that you cannot say later who brought whom, and the payout becomes a negotiation instead of a number.

Step 2: Decide how guests identify themselves

Someone at the door has to establish that the person in front of them is on the list. A name alone only does that while nobody has an incentive to know it.

A personal, single-use code solves two problems at once: it cannot be guessed, and a second scan shows up immediately. That is the difference between "is on the list" and "has not come in yet".

Step 3: Set the capacity you actually have

Not the room capacity — the number past which you stop letting people in. It sits lower, because you need headroom for guests without a listing, artists, crew and latecomers.

And plan around no-shows. On guest lists, twenty to forty percent of the people who sign up typically do not turn up. Filling exactly to capacity leaves you half empty; overbooking blindly gives you a fight at the door. The number you want is your own, from your last few events — not the rule of thumb.

Step 4: Work out how the door reads the list

A list only you can open is not a list once the night starts. Before first doors, settle three things: which devices hold it, what happens when the network drops, and who records a late approval.

The offline case is the one most often missed. There is more detail in the guide to planning door check-in.

The short version

If you would rather not assemble that yourself: EventSync ships sign-up links, promoter attribution, single-use codes and the offline scanner together.
