A booking system from tentacl.ai accepts bookings around the clock, shows free rooms, holiday homes, vehicles, yachts or pitches live, collects deposits and final payments, and runs the guest account through to departure. For hotels, holiday rentals, campsites, car rentals and yacht charters it is a ready-made product, in daily use since summer 2026. For appointment-based businesses such as studios, practices and service providers we build appointment booking on the same core. The price is fixed, there is no commission per booking.
Everything that happens between inquiry and departure, in one system. No spreadsheet on the side, no phone book of deposits.
Guests choose a room, holiday home, vehicle, yacht or pitch with photos, amenities and final price, optionally on the house or site plan. Blocks, seasons, minimum stays and holiday rules are checked before the booking.
Free slots per employee or resource, buffer times, email reminders. Built on the same core for studios, practices, consultants and workshops.
Nexi or Stripe, Apple Pay and Google Pay, bank transfer in advance, security deposit as a pre-authorization. Refunds on cancellation according to your rules, discounts and vouchers included.
Every guest sees their bookings, invoices and the wallet card for their phone. Rebooking and late check-out without calling reception.
Tourist tax and guest registration for accommodation, driver's or skipper's license check for rentals, invoices with correct VAT. Electronic reporting to the municipality on request.
A front-desk view of the day's arrivals or handovers, payment on site, end-of-day closing. Who's arriving, what's open, who's extending: all on one screen.
