Master build prompt for an appointment & booking SaaS
The build prompt for a booking SaaS with calendars, availability rules, an online booking page, reminders and payments or deposits.
Built for: Builders of tools for hair salons, clinics, studios and consultancies
In scheduling products, the complexity lives in the calendar: time zones, buffer times, resource/room conflicts, cancellation policies and Google Calendar sync. Get it wrong and double bookings are inevitable.
The prompt defines the availability engine, the booking state machine, the reminder and no-show flow, deposit/cancellation rules and a public booking page for each business.
