One clear price. Extras only when you actually need them.

No. Camping is an important use case, but not a requirement. Use it for holiday homes, vehicles, bicycles, boats, rooms, pitches or your own rental categories — separately or together.

No. 0% commission. You pay €49.90 per month or €499 per year, plus the one-time €149 setup fee.

It depends on how many of your bookings run through portals or agents today — only those cost commission. There is a calculator on the homepage: set bookings per month, average booking value, the share via agents and your commission rate, and you see straight away what it adds up to per year. The one-time setup fee is already deducted there, and your payment provider's fees apply either way.

Yes. Choose the Calendar Sync for €19.90/month per business if you only need occupied dates exchanged with Airbnb and Booking.com via iCal. It includes all accommodation but is not real-time and does not transfer rates, guest details or messages. For automatic reservations, availability, rates and minimum stays, choose the full Channel Manager for €79.90/month per business or location. Both are optional and the standard package also works without them.

Yes. KISB is an installable web app (PWA) included with the booking system. On iPhone and iPad add it from Safari via Share → Add to Home Screen; on Android use Install app in the browser. It then opens from its own icon without browser bars and receives KISB updates automatically. A separate App Store download is not required.

Yes. You can send us ideas from your day-to-day operation at any time. We personally review every suggestion and prioritise improvements that help several businesses. A submission is not yet a promise of implementation or a fixed date; released improvements to the shared system are included with every active subscription.

No. Bookings, payments and channel synchronisation work without AI. Claude by Anthropic is used only for the optional guest chat. The visitor's message and the business information approved for the answer are transmitted; personal booking, customer and payment data from KISB is not included.

Yes, and it works in your favour: your early bookings arrive in winter. Switching the booking page off in January costs you exactly the reservations for the coming season. The yearly plan is €499 — with a six-month season that is around €83 per season month, at 0% commission on every booking. If you really need a break, you can cancel monthly: your units, prices and guest data stay stored, and we reactivate your account as soon as you come back — just email info@keepitsimplebooking.com.

Production booking and customer data is stored on Hetzner servers in Germany. Hetzner is a German data centre and cloud provider certified to ISO/IEC 27001:2022; its cloud services also hold a BSI C5 Type 2 attestation. Data sent between the browser and the system is encrypted. Our databases are backed up automatically every day; the backups are also encrypted and stored separately from the running system. This allows us to restore data after a technical failure. We never store payment card details; Stripe handles them. No reputable provider can promise absolute protection against every possible data loss. ID data is not collected by default — only if your site enables the optional ID verification.

Yes. You decide: fixed deposit, full prepayment, or even no deposit at all. Optionally with a booking fee or no-show protection.

Yes. Add your logo, invoice details, taxes and bank account once. You can then create and send an invoice from each booking and record bank transfers in its payment history. Stripe payments are recorded automatically. If you choose, KISB can also issue invoices automatically when a booking is confirmed or paid.

No. You can simply use a booking link or place a button on your existing website. On request, we can also build you a simple website with integrated booking.

After the purchase your system is set up — booking link and admin access arrive by email within minutes. You then add units, prices and seasons yourself, guided by tours right in the system. New: you can also simply describe your site to your AI — ChatGPT, Claude or any other — and import the finished list in one go, with a preview before anything is created. Existing bookings can be imported via CSV — and we help whenever you need us.

Yes. Open the live demo right in your browser — no registration, with sample data. Try the guest booking flow and the admin area as much as you like.

Yes. Subscriptions and cancellations are handled via Stripe at the end of the billing period.

Yes. CSV/Excel export is included in Keep it Simple.
