Launch a booking system for your clients in days, not weeks
A production-ready booking starter kit: a timezone-safe availability engine, Stripe payments, reminders, and an admin your clients can actually use. Vertical presets for sports clubs, salons, and clinics.
Early-bird presale: €69 for waitlist members · regular price €99
Everything a booking system needs, pre-built
The hard 20% that takes weeks — availability logic, payments, edge cases — done and tested, so you ship the client project in days.
DST-safe availability engine
Weekly hours, holiday overrides, buffers, and double-booking prevention at the database level. UTC storage, business-timezone logic.
Stripe payments, three modes
Deposit, full payment, or pay-at-venue — configured per service, with a retry-safe payment and confirmation flow.
Reminders: email now, WhatsApp-ready
Confirmation and reminder emails out of the box; a clean notification abstraction so WhatsApp Business drops in later.
Admin dashboard your clients can use
Services, opening hours, overrides, bookings list, manual phone bookings, and no-show tracking — in plain language.
Vertical presets
Courts, salons, and clinics: each preset ships seeded demo data, domain copy, and theming, so the demo looks real on day one.
IT/EN i18n + GDPR kit
Two languages from day one, cookie banner done properly, privacy pages, and data-retention defaults. Built for Italian clients first.
The interface, before you buy
What the kit's design looks like: the public booking page your client's customers use, the admin your client gets, and the engine code you maintain.
-- double-booking impossible at DB level EXCLUDE USING gist ( resource_id WITH =, tstzrange(starts_at, ends_at) WITH && ) WHERE (status IN ('pending','confirmed')); -- UTC storage, business-tz day boundaries -- DST-safe: 09:00 local stays 09:00, always
