How to set up a class or event waitlist

Updated 2026-07-02

To set up a waitlist, give your form a capacity and enable the waitlist. When every spot is taken, Jupiter Signup marks the option sold out and captures further interested people on a waitlist, with their name and email, instead of turning them away.

Steps

1. 1 Add a capacity Tell the builder how many spots there are, for example "cap the class at 15". The form then shows how many places are left.
2. 2 Turn on the waitlist Ask for a waitlist, for example "add a waitlist when it's full". Once capacity is reached, the form keeps collecting names on the waitlist.
3. 3 Watch it fill The form marks the option sold out automatically at the limit; the limit is enforced on the server, so you never oversell.
4. 4 Offer freed-up spots When someone drops, the results view shows the waitlist in order so you can offer the open spot to the next person.

Frequently asked questions

Do waitlisted people pay?

You choose. A common setup is to capture the waitlist for free and only charge once you offer them a confirmed spot.

Is the limit actually enforced?

Yes. Capacity is recomputed on the server on every sign-up, so a form can't be oversold even under a rush.

What does Jupiter Signup cost?

There is no monthly plan. It takes a flat 2% of what you collect, on top of Stripe's normal processing fee. A sign-up that does not charge is free.
