We connect to all of it. Your lock, your payment provider, your portals stay right where they are.

All data via API and export. Tax advisor, website, lock system, cleaning company.
Door code from the booking for your smart lock or key box, guest registration, payment with deposit and balance, portals with no double bookings. Named brands belong to their owners; we connect to their systems, we do not sell them.
We'll show you the system live in 30 minutes, with demo data from your industry. It is the same platform that has been handling bookings, payments and arrivals every day since summer 2026 at our reference business on Lake Constance, with real availability and real prices.
What's on this page is built and running. Not a prototype, not an announcement, not a slide.
tentacl.ai builds booking and operations systems for hosts and rental businesses: hotels, holiday rentals, car rentals and yacht charters. We come to you before rollout, set up the system for your business, and are there for the go-live. After that, you reach us directly, with no hold queue and no ticket number.

Same-day response on weekdays. During the season we're also there on Saturdays, with a fixed phone number instead of a hold queue.
The booking flow, payments and servers are monitored around the clock, including nights and weekends. Anything unusual shows up in the morning report before a guest notices.
Not the other way around. Your seasons, your rules, your map layout. We build in whatever makes your business distinct.
Underneath the booking flow is not a homegrown silo system, but Odoo: the business software that more than 13 million people worldwide work with. On top of that, we built what didn't exist yet for your kind of business.
Accounting with DATEV export, invoicing and dunning, point of sale, inventory for the kiosk and shop, staff and time tracking, reports. We don't have to build any of that, it's already there and proven for years. No second program, no manual data export.
The booking flow with unit selection, the guest account, the door code on the phone, final cleaning, tourist tax and guest registration, waitlist, morning report and the watchdogs that run at night. Everything a business needs that standard software doesn't cover.
Odoo is open. Your data lives in a standard database, fully exportable at any time. Even if you leave one day.
A second property, shop, bike rental, more staff: there are ready-made building blocks for that, instead of a request to the vendor.
Emails are read and sorted, payments matched, reports written. Not as a gimmick, but wherever someone would otherwise be typing.
Almost everyone charges per unit. We don't. Whether your business has fifty units or a thousand makes no difference to us — you pay for what the system should be able to do. No commission per booking.
Your team works at the front desk instead of on paper.
Your guest books it themselves. No commission to the portal.
Your team knows each morning what's coming up.
Your business organizes itself.
Every module can be booked on its own, starting at €30 a month. As soon as a package is cheaper than the individual parts, we automatically bill the package — you never pay more than necessary. In the configurator you put your package together yourself and see the price instantly.
Data from your old system, units and house plans, pricing rules, training your team. You just choose whether to pay it once or spread it over 24 months. With the spread-out option, the installment drops away from month 25, and you only pay the base amount from then on.
We visit you two to three times: seasons, rules, point of sale, guest registration.
We set everything up: your map layout, your prices, your emails.
We bring over guest records and bookings from your old system. Nothing gets lost.
We train reception, team and accounting on your real cases.
We're there for the first days. After that: a fixed phone number, morning report, monitoring.
Open slots straight from our calendar. You book it yourself, and you'll get the video link by email right away. There's nothing you need to prepare.
Weekdays, 30 minutes, no sign-up

You do. Guest records, consents and booking history live in your own tenant on servers in Germany and can be exported in full at any time. Even if you leave one day.
Nexi and Stripe, each with credit card, Apple Pay and Google Pay, a deposit with a later balance payment, refunds on cancellation according to your tiers. PayPal via Stripe.
No. A fixed monthly amount, plus a one-time setup fee. What your business earns stays with you.
Six to ten weeks. Existing bookings are carried over, and the guest won't notice the switch at all, except for a better booking page. For 2027 founding customers: go-live by March 15, otherwise no license until the start.
Because it makes no difference to us. A business with a thousand units costs us no more work than one with fifty — the same software, the same support. So you pay for what the system should be able to do. If you only want to digitize the front desk, that's all you pay for.
Yes. The bread roll service runs as a standalone product, with your existing software or on its own: €199 setup, then €333 per season or €444 per year. As a module of this platform, it costs €49 a month.
Go-live guarantee by March 15, data migration included, half-price license in winter. After that, the regular terms apply.
