A HIIT class registration form books people into a high-intensity class and collects payment at signup, whether you price by drop-in, pack, or monthly pass. Describe your classes and Jupiter Signup builds it: each class as a capacity-limited paid option, packs and monthly passes as paid choices, Stripe checkout, and a waiver with a health acknowledgment.
Floor space and equipment cap a HIIT class, so a booked spot needs to be a paid spot. Charging at signup fills the class to its limit and spares you from collecting drop-in cash at the door.
Connect your own Stripe account and Jupiter Signup collects the fee as people register for a HIIT class, whether you charge a flat price, per session, or a pack. It takes a flat 2%, with no monthly fee required.
Yes. Give each option a capacity and the form shows spots left, then marks it sold out. The limit is enforced on the server, so it can't be oversold. Turn on the waitlist and the form collects names once everything on it is full; you email people yourself when a spot opens.
There is no monthly plan required. 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.
About a sentence. Describe your sign-up and Jupiter Signup builds the whole page in seconds, then you edit anything by chatting. No account is needed to try it.
