A wedding invitation and RSVP site with a fixed launch date, built in Ship Studio with a multi-step form for guests who only get one attempt.
Michael and Oliver needed an invitation site with RSVPs collected online. The date was fixed, the RSVP cut-off was fixed, and the guest list ran across every age group and device you can think of.
It is one page, built at the mobile breakpoint, because invitations get shared by message and opened on a phone. Everything a guest needs sits in that one scroll: what the day is, where it is, how to get there, and the form.

Early exploration
A wedding RSVP form asks for more than a name. Attendance, plus ones, dietary requirements and the rest add up fast, and a single long form is where guests give up.
The hard constraint was that guests get one attempt. A form that fails silently on an older phone does not generate a support ticket, it generates a missing RSVP that nobody notices until the numbers are wrong.

Working through the structure
A form in steps rather than one long page. The RSVP is split so a guest answers a few questions at a time, one submission per guest rather than one per household. Short steps are easier to finish on a phone and they make it obvious how much is left, which is what stops people abandoning halfway through.
Saved to the home screen like an app. Guests are prompted to add the page to their home screen, so it sits with their apps rather than buried in a message thread they have to find again months later. It also gives the couple somewhere to post updates as details firm up.
Answering the questions before they get asked. Can I bring a plus one. Do I need a visa. Where should I stay. The FAQ and travel sections cover what a destination wedding generates, down to the practical detail on flights, eSIMs and the arrival card. Every answer on the page is one message the couple does not have to reply to.
The day laid out in order. A countdown, what to expect, the boat itself, what is included, and a map of the route along the Chao Phraya. Guests who have never been to Bangkok get the shape of the day without having to ask anyone.
