What you can build

Sell spots as priced items. The server recomputes every charge from the catalog, so the page can never be tampered with to change a price.

Offer a bundle that covers several items at a better price; buying it counts toward each thing it includes (including their capacity).

Optional extras a person can tack on to their sign-up.

Payments are optional. A form can charge, be entirely free, or mix paid and free options — and no price or total shows when nothing costs money.

Automatic quantity discounts, applied and re-checked on the server so the total is real.

Time-limited pricing that ends on a date.

Collect money for real via Stripe Connect, with a small platform fee. Today the charge is computed and previewed, but no money actually moves yet.

Cap how many can take an option. The form shows how many are left, disables the option when it fills, and the server refuses to overbook.

Let people choose at most (or at least) a set number from a group of options.

Stop people choosing two options that can't go together — like two sessions in the same time slot.

Ask for whatever you need — short text, email, phone, numbers, dropdowns, or longer paragraphs — and mark any of them required.

Add a phone field to the form with one toggle.

Email people a confirmation after they sign up.

Remind people before the event or session.

Send people to a waitlist once a capped option fills up.

Every form gets its own link to share anywhere.

Drop the form into your own web page as an embed.

See every response in a table and ask plain-English questions about them.
