How it gets onto your website
Three ways, we build it in
Button or link
“Book an appointment” in your menu or on the contact page – the quickest way.
Embedded
The booking calendar appears directly on your page, loaded only after a click (privacy).
Plugin
In progress for WordPress, Shopware and Joomla: bookings and calendar right in your website's backend.
We take care of the installation on any website, even if we did not build it.
Set-up
Ready in three steps
Appointment types, durations, opening hours, which emails go to whom.
Account, booking page, calendar, emails in your name, installation on the website, test booking with you.
Desktop and phone, plus a short written guide. After that: changes on request.

Frequently asked
What practices want to know beforehand
Where is the data stored?
On our own servers at Hetzner in Nuremberg. No US services, nightly backup. You receive a data processing agreement from us.
Can I keep using my current calendar?
Yes, the practice calendar can be added to Apple Calendar, Thunderbird or Outlook. Private calendars stay out.
What happens when I enter an appointment myself?
It blocks the slot for online booking. The patient gets no confirmation, only the reminder if you add their email address.
What about double bookings?
Every slot can be booked only once, whichever website it comes from or whether you filled it yourself.
Can I set buffers and lead time?
Yes: minimum lead time, breaks between appointments, how far ahead bookings are allowed, how many per day.
What does a later change cost?
Appointment types, hours and email texts are changed within the subscription, at no extra charge.
