The panel's verdict
eTermin, an online appointment scheduler from eTermin GmbH of Schwyz, Switzerland, scored strongest on integrations and data and calendar and availability: a documented REST API with webhooks, connectors including Salesforce, Pipedrive, Zapier and Make, and automatic Zoom, Teams and Google Meet links, alongside two-way iCloud sync, buffers, public-holiday import and rooms and devices blocked automatically with the booked person. Reminders and no-shows sits at 7, on email, SMS and WhatsApp reminders, deposit or full prepayment at booking, and a waitlist that refills cancelled slots. The genuine split is sovereignty, scored 4 to 7: higher scores credit hosting in a C5-certified data centre in Frankfurt am Main and an electronically signable Article 28 GDPR agreement, while lower ones weigh the Swiss contracting entity under Swiss law and venue and found no public information on the application's own subprocessors — hosting, SMS gateway, email delivery — or on ISO 27001 or SOC 2 certification. Pricing transparency holds at 6: Lite at € 19 and Pro at € 29 per month are published, but the add-ons carry no prices.
Speaks for it
- A documented REST API with webhooks, code examples and connectors including Salesforce, Pipedrive, Zoho, Zapier and Make lifted integrations and data to 7 to 8.
- Two-way iCloud synchronisation plus Google, Outlook, Exchange and CalDAV, with buffers, automatic public-holiday import and rooms and devices blocked automatically alongside the booked person.
- Automatic confirmations and reminders by email, SMS and WhatsApp, with deposit or full prepayment at booking and a waitlist that automatically refills cancelled slots.
- An Article 28(3) GDPR data processing agreement can be signed electronically, and hosting is stated in a C5-certified data centre in Frankfurt am Main.
- Lite at € 19 and Pro at € 29 per month are published with a feature comparison and a 30-day trial without a credit card.
Held against it
- Sovereignty scores split 4 to 7 over the Swiss contracting entity under Swiss law and venue, and we found no public information on the application's own subprocessors or on ISO 27001 or SOC 2 certification.
- Extra calendars, SMS, integrations and locations are named as add-ons without prices, and Enterprise and multi-location setups are individual quotes, so a full annual cost cannot be computed.
- We found no public information on a documented full export of bookings, customers and form answers, while the terms place the pre-termination download duty on the customer.
- The captured pages give different cancellation terms — "Jederzeit kündbar" on the pricing page against a two-calendar-week notice period in the terms.
- The terms require a visible link to the vendor's site whenever the booking tool is embedded in a business's website.
Best for
- You run a salon, practice or service business where rooms, devices and staff must be booked together and blocked automatically — calendar and availability scored 7 to 8.
- You fight no-shows with payment — deposits, mandatory prepayment for selected services and a waitlist that refills cancelled slots are documented, and reminders and no-shows sits at 7.
- You want to wire bookings into a CRM or automation platform — a documented REST API, webhooks, Zapier and Make are published.
- You serve German-speaking clients and value an electronically signable Article 28 GDPR agreement, hosting in Frankfurt am Main and German-language support.
Avoid if
- Your procurement requires EU jurisdiction or a closed list of the application's subprocessors — the terms name Swiss law and venue, and the named subprocessors cover only the vendor's own website (Zendesk for support pages, Tapfiliate for the partner program).
- You must compute your full annual cost before committing — ask the vendor: the public pages we read do not show it
- You need a documented structured export of bookings, customers and form answers at exit — the pages document PDF printing and a contractual duty on the customer to download data before the contract ends.
- Your team relies on automatic or round-robin assignment of bookings — the documented model is clients choosing a preferred employee, and the judges found no public information on automatic distribution.

Booking page & client experience
Show reasoningHide reasoning
How this is scored
What the person booking sees and can do: a booking page with the services or meeting types on offer, their durations and prices, booking questions, an embed or widget for the business's own website, time zones and languages, group or class bookings, and links to reschedule or cancel without calling.
0 — Not a booking product: no page or widget where a customer picks a slot; appointments are entered by staff only.
3 — A booking page or form exists, but the pages say little about how it works: types of appointment, booking questions, embedding and rescheduling are not described.
5 — A booking page with several appointment or service types of their own duration, custom booking questions, and a way to put it on the business's website (link, embed or widget); confirmations carry a link to reschedule or cancel.
8 — In addition: group or class bookings with seat limits, booking pages in several languages with automatic time-zone handling, branding without the vendor's logo, multi-step selection of service, staff member and location, and a booking flow the vendor states is accessible or mobile-optimised.
10 — Booking as a finished storefront: packages, memberships or recurring bookings, intake forms with conditional questions, booking from Google or other directories, a customer account with booking history, and an accessibility statement for the booking pages published.
The Practice Owner
Patients can book around the clock as guests, through our website or an embedded widget, or straight from Google Search and Maps, and cancel themselves via a direct link — most of what my front desk needs. The page adapts to our corporate design down to CSS, supports group slots for courses, several languages on Pro, and is stated as mobile-optimised. I take off because the terms require a visible notice linking to the vendor's own site when the tool is embedded, and I found no public information on automatic time-zone handling or an accessibility statement. 8 9 2 6
The Salon Owner
Direct 24/7 booking, a cancellation link for clients, the page adaptable to our corporate design with CSS, embedding in our own website, and preselection of services plus the client's preferred employee — that covers what a Saturday-booked salon needs. Group bookings for courses, pages in several languages and booking straight from Google Search and Maps are documented as well. I found no public information on an accessibility statement or intake forms with conditional questions, and the terms require a visible link to the vendor when the booking page is embedded. 8 9 2 11 6
The Sales Team Lead
Multi-step preselection of services and staff, embedding on the company's website with corporate-design and CSS customisation, mobile optimisation, guest or registered booking, a direct cancellation link, booking straight from Google Search and Maps, and group bookings for courses are all documented. We found no public information on automatic time-zone handling, conditional intake questions or a published accessibility statement, and the terms require a visible link to the vendor's site when the booking page is embedded. 8 9 2 12 6
The Independent Consultant
The captured pages document a booking page adaptable to my corporate design with CSS, embeddable in my website, mobile-optimised, with multi-seat bookings for courses, several languages on Pro, guest booking, a direct cancellation link for clients, and booking straight from Google search and Maps. The terms, however, require a visible vendor link when the tool is embedded, and I found no public information on automatic time-zone handling, an accessibility statement or conditional intake questions. 2 6 8 9 12
The Data Protection Officer
The pages show a customizable booking page that embeds into the practice's own website and is bookable through Google Search, Google MyBusiness and Maps, with group bookings for courses, booking pages in several languages, mobile optimisation, guest or registered booking, and customer cancellation via direct link. Two things temper this for a professional practice: the terms require a visible notice linking to the vendor's site when the booking tool is embedded, and we found no public information on seat limits for group bookings, automatic time-zone handling, or an accessibility statement for the booking pages. 2 6 8 9
The Skeptic
The pages show a customizable booking page with CSS corporate design, embedding in the company website, booking via Google search and Maps, guest or registered booking, several languages in the Pro plan, mobile optimization, course-style multiple occupancy, and cancellation by customers via direct link. We found no public information on time-zone handling, seat limits for group slots, or an accessibility statement, and the terms require a visible eTermin link whenever the booking tool is embedded in a business's homepage. 8 9 2 6 12
Calendar sync & availability rules
Show reasoningHide reasoning
How this is scored
How the product knows when someone is free: two-way sync with Google, Microsoft 365 and Outlook, iCloud or CalDAV, conflict checks across several calendars, working hours and exceptions, buffers, minimum notice and booking windows, daily limits, and rooms or equipment that must be free as well.
0 — No calendar: no availability is kept and no sync with any calendar is offered.
3 — An internal calendar or a one-way export (iCal feed), but no stated two-way sync and few availability rules beyond opening hours.
5 — Two-way sync with Google and Microsoft calendars that blocks booked times, working hours with exceptions, and buffers or minimum notice per appointment type.
8 — In addition: several calendars per person checked for conflicts, iCloud or CalDAV, booking windows and daily or weekly limits, holidays and absences, and resources (rooms, equipment, chairs) that must be free alongside the person.
10 — Availability that runs a multi-site business: per-location and per-resource schedules, capacity rules across staff and rooms, sync behaviour and latency documented, and changes in any connected calendar reflected without double bookings, as stated in the documentation.
The Practice Owner
For my two treatment rooms this is the decisive one: several resources — employee, room, device — can be required in a single booking, and resources are blocked automatically when a specific therapist is booked, which is exactly rooms and people checked together. Sync covers iCloud, Google, Outlook, Exchange and CalDAV with iCloud explicitly bidirectional, plus buffers between appointments, automatic import of public holidays and per-resource working hours. I found no public information on minimum-notice or booking-window rules, or on documented sync latency. 10 11 16 8
The Salon Owner
Buffers and pre- or post-processing time between appointments, different working hours per week and per employee, automatic import and blocking of public holidays, and rooms or devices blocked automatically alongside the booked stylist — this would run both my salons. Two-way synchronisation is documented for Apple iCloud, with Google, Outlook, Exchange and CalDAV sync also named. I found no public information on conflict checks across several calendars per person, on booking windows or daily limits, or on sync latency and double-booking prevention. 8 10 11 16
The Sales Team Lead
Sync with Google, Outlook, Exchange, CalDAV and iCloud is stated, with two-way direction explicit for iCloud, plus buffers, holiday import and blocking, per-employee working hours with varying weekly hours and shift plans, and rooms and devices bookable alongside the person and blocked automatically when an employee is booked. The captured pages do not state the direction for Google and Outlook sync, and we found no public information on booking windows, daily limits or documented sync behaviour. 1 10 11 16 8
The Independent Consultant
My private calendar is respected: automatic synchronisation with iCloud, Google, Outlook, Exchange and CalDAV is documented, with the iCloud link explicitly in both directions, plus buffer times around appointments, automatic public-holiday import with blocking, different working hours in different weeks, and rooms or devices bookable and blocked automatically alongside me. I found no public information on minimum notice, booking windows, daily booking limits or documented sync behaviour. 1 8 10 11 16
The Data Protection Officer
Synchronisation with iCloud, Google, Outlook, Exchange and any CalDAV calendar is documented, and the iCloud interface is stated to synchronise in both directions; buffers, working hours that vary by week, automatic import of public holidays with blocking, and resources such as rooms and devices bookable alongside a specific employee are all described. We found no public information on conflict checks across several personal calendars, daily or weekly booking limits, or documented sync behaviour and latency. 2 8 10 11 16
The Skeptic
Automatic synchronization with iCloud, Google, Outlook, Exchange and CalDAV is documented, with the iCloud interface explicitly bidirectional, and availability rules cover buffers, per-resource working hours, differing hours by week, public-holiday import and blocking, and rooms, devices and staff that are booked and blocked together. We found no public information on checking several external calendars per person for conflicts, booking windows, daily or weekly limits, or documented sync latency and double-booking behaviour. 10 16 11 8 1
Team, staff & location scheduling
Show reasoningHide reasoning
How this is scored
How bookings are shared out across more than one person: staff profiles and the services each offers, round-robin and collective (all-hands) meetings, routing forms that send a booking to the right person, several locations, roles and permissions for admins and staff, and single sign-on for larger teams.
0 — A single-user tool with no way to add staff or a team.
3 — Several users or staff calendars can be added, but how bookings are distributed among them and who may change what is not described.
5 — Several staff or team members with their own availability, the customer choosing a person or the system assigning one (round-robin or "any available"), and an admin role that manages the team.
8 — In addition: weighted or priority round-robin, collective bookings that need several people at once, routing by form answers, several locations with their own staff, granular roles and permissions, and reporting per staff member.
10 — Scheduling as a team system: SSO and user provisioning (SAML, SCIM), routing that takes ownership from a CRM, managed templates the organisation pushes to every member, audit logs of changes, and distribution fairness reported.
The Practice Owner
Each of my six therapists can have an independent calendar with their own profile and availability, patients can choose a preferred therapist, and user management with access rights per employee and location comes with Pro. But I found no public information on round-robin or automatic assignment, collective bookings needing several people at once, routing by booking-form answers, or reporting per staff member. 10 11 2 3
The Salon Owner
Each stylist gets their own calendar with a profile, picture, availability and bookable services, and the client can pick their preferred employee — the core of what I run. Roles, rights and access per employee or location, multi-location management, and staff management are documented, with single sign-on via OpenID on request at Enterprise. I found no public information on round-robin or weighted distribution, routing by form answers, or reporting per staff member. 10 11 2 3 12
The Sales Team Lead
Independent calendars per employee and resource with own profiles, services and availability, customer choice of preferred employee, user management with permissions per employee and location, and single sign-on on request are documented. Distribution is what my team lives on, and we found no public information on round-robin or weighted assignment, routing by form answers or CRM ownership, or collective meetings needing several people at once. 10 11 2 3 12
The Independent Consultant
Every staff member gets an independent calendar with a profile, picture, own availability and a working-time planner, clients can choose a preferred person, and roles and rights are set per employee or location with multi-branch management on Pro — enough for me plus the occasional associate. I found no public information on round-robin or automatic assignment, collective meetings, or routing by form answers. 2 3 10 11
The Data Protection Officer
Independent calendars per employee and resource with their own profile and availability, customer selection of a preferred employee, per-user permissions, and roles and rights per employee or location are documented, with OpenID and single sign-on offered on request in the Enterprise package.

The Skeptic
Independent calendars with their own profile, image and availability per employee and resource, customer selection of a preferred staff member, granular per-user rights, and multi-location management in the Pro plan are documented; single sign-on via OpenID is offered "auf Anfrage" in Enterprise.

Reminders, payments & no-show protection
Show reasoningHide reasoning
How this is scored
How the product keeps a booked slot from turning into an empty one: confirmations and reminders by email and SMS, payment or deposit at booking, cancellation and late-cancellation policies, fees for no-shows, waiting lists that refill cancelled slots, and follow-ups after the appointment.
0 — No notifications to the person booking: no confirmation, no reminder.
3 — Email confirmations are sent, but reminders, payments and cancellation rules are not described.
5 — Automatic email reminders with configurable timing, SMS reminders (included or as a paid add-on), and payment at booking through at least one named provider such as Stripe or PayPal.
8 — In addition: deposits or partial prepayment, a cancellation deadline the system enforces, no-show or late-cancellation fees, a waiting list that fills freed slots, and follow-up or review messages after the appointment.
10 — No-show protection as a measured process: no-show rates reported, card-on-file or pre-authorisation charged by policy, reminder channels per customer (email, SMS, messenger), refunds and vouchers handled in the product, and the cancellation and payment terms shown to the customer configurable per service.
The Practice Owner
Automatic confirmations and reminders by email, SMS and WhatsApp are explicitly pitched at cutting no-shows, deposits or full prepayment can be required at booking through named providers, and a waitlist automatically refills a cancelled slot with the resulting notifications — close to my whole wish list. What I miss is public information on an enforced cancellation deadline, late-cancellation or no-show fees, or configurable reminder timing. 2 13 14 10
The Salon Owner
Automatic confirmations and reminders by email, SMS and WhatsApp, a deposit or full payment definable per service, mandatory online payment for selected services with PayPal, card and more, and a waitlist that automatically refills a cancelled slot — the colour-appointment deposit is covered. The pages also tie prepayment to fewer no-shows. I found no public information on a no-show or late-cancellation fee, a cancellation deadline the system enforces, card-on-file pre-authorisation, or refund handling. 2 13 14 8 16
The Sales Team Lead
Automatic confirmations and reminders by email, SMS and WhatsApp, deposits or full prepayment at booking through named providers, mandatory prepayment per selected service, and a waitlist that automatically refills cancelled slots with its own confirmations are all documented. We found no public information on an enforced cancellation deadline, no-show or late-cancellation fees, or configurable reminder timing. 2 8 13 14
The Independent Consultant
This hits my core list: automatic confirmations and reminders by email, SMS and WhatsApp, payment taken directly at booking through named providers such as PayPal, Klarna and Mollie, deposits or full prepayment definable, payment mandatory for selected services, and a waitlist that automatically refills cancelled slots — the payment page even frames prepayment as no-show protection. I found no public information on a system-enforced cancellation deadline, late-cancellation or no-show fees, or configurable reminder timing. 2 8 13 14 16
The Data Protection Officer
Automatic confirmations and reminders by email, SMS and WhatsApp are stated, along with a deposit or full payment definable per service through named providers, a waiting list that automatically refills cancelled slots, and automated messages informing bookers about past appointments.

Integrations, API & data export
Show reasoningHide reasoning
How this is scored
What the product connects to and how the data gets out again: video-meeting links (Zoom, Teams, Google Meet), CRM and marketing tools, automation platforms (Zapier, Make), a documented API and webhooks, website and app-store integrations, and an export of bookings and customer records.
0 — No integrations and no export; bookings stay in the product.
3 — A few named integrations or an export of bookings, but no API or webhooks described.
5 — Video-meeting links created automatically for at least one named tool, a connection to an automation platform or a few named CRM or marketing tools, and an export of bookings or customers.
8 — In addition: a documented public API and webhooks, native CRM integrations named (HubSpot, Salesforce or similar), an integrations directory, and a full export of bookings, customers and booking-form answers.
10 — Built to be connected and left: an API covering every object with its documentation and rate limits published, embeddable components or an SDK, a self-hosting or open-source option or a stated migration path, and the complete account data exportable in a documented format.
The Practice Owner
A documented REST API with webhooks for created, modified and deleted appointments, code examples and the statement that almost every object can be manipulated, together with Zapier and Make, named CRM partners such as Salesforce, Pipedrive and Zoho, and automatic Zoom, Teams or Webex meeting links — more than my practice will ever use. The weak spot is getting data out: the calendar prints to PDF and the terms put the download duty on the customer before the contract ends, but I found no public information on a documented full export of bookings and customer records. 15 16 10 6
The Salon Owner
A documented REST API with webhooks when appointments are created, modified or deleted, code examples, Zapier and Make, native connectors to Salesforce, Pipedrive and Zoho, automatically created Zoom, Teams and Google Meet links, and a full connector directory including payment providers. The terms make the customer responsible for downloading their data before the contract ends, so an export exists. I found no public information on published rate limits, a self-hosting option, or a documented export format covering booking-form answers. 15 16 1 6
The Sales Team Lead
A documented API with all four REST verbs, key-based signing and code examples, webhooks on created, modified and deleted appointments, the statement that almost every object can be manipulated via the API, automatic Zoom, Teams and Google Meet links sent to the booker, and named CRM partners such as Salesforce, Pipedrive and Zoho plus Zapier and Make give me most of what my reps need. We found no public information on rate limits or a documented full export format; the terms place the download of data before contract end on the customer. 1 6 10 15 16
The Independent Consultant
The strongest section: a documented REST API with key-and-signature authentication, all four verbs, webhooks on created, modified and deleted appointments, and code examples in four languages, plus Zapier and Make connectors, automatic Zoom, Teams and Google Meet link creation, and a categorised directory naming Salesforce, Pipedrive and Zoho among many partners. The soft spot is export — PDF printing of the calendar and a duty to download my data before the contract ends — and I found no public information on a documented full export of customers and booking-form answers. 6 10 15 16
The Data Protection Officer
A documented REST API with its URL, authentication scheme, code examples and push notifications when an appointment is created, modified or deleted sits alongside named native CRM connections, automation platforms, and automatic Zoom, Teams and Google Meet link creation. For a practice's records this is where I hesitate: export is evidenced as PDF print-outs of the calendar and a contractual duty on the customer to secure their data by download before the contract ends, and we found no public information on a documented structured export of bookings, customers and booking-form answers, on published rate limits, or on a stated migration path. 1 6 10 15 16
The Skeptic
A documented REST API with an authentication scheme, all four verbs, code examples and webhooks for created, modified and deleted appointments sits beside named native integrations (Salesforce, Pipedrive, Zoho, Zoom, Teams) and automation platforms including Zapier and Make. Getting the data out is the weak link: the pages show PDF print views and a terms clause making the customer responsible for downloading their data before contract end, and we found no public information on a documented full export of bookings, customers and form answers, on rate limits, or on a self-hosting or migration path. 15 16 6 10

How this is scored
Who the contracting entity and the parent company are, where booking and customer data is hosted, and who the subprocessors are: hosting, the SMS gateway, email delivery, payment providers, video tools and analytics. Independently sourced by the sovereignty pipeline; booking data names who sees a doctor, a lawyer or a therapist and when, so the whole chain counts, not only the database.
0 — Non-EU vendor and contracting entity, no data processing agreement offered, and neither hosting location nor subprocessors stated.
3 — A privacy policy and a data processing agreement exist, but the vendor and hosting are outside the EU (or hosting is unstated) and subprocessors are not listed.
5 — A data processing agreement and a subprocessor list are published, and either EU hosting or an EU contracting entity is stated, while parts of the chain (SMS, email, analytics, support) run through non-EU providers.
8 — EU contracting entity and EU hosting on named infrastructure, subprocessors listed with their locations, a data processing agreement published, and security certifications (ISO 27001, SOC 2) stated.
10 — Sovereign end to end and evidenced: European ownership, entity, hosting and every subprocessor including SMS and email, data export and deletion documented, and certifications published with their scope rather than implied.
The Practice Owner
The two things I must be able to show are there: a data processing agreement under Article 28 GDPR that can be signed electronically and sits in the backend, and hosting stated to run in a C5-certified datacenter in Frankfurt am Main in Germany. But the contracting entity is eTermin GmbH in Schwyz, Switzerland, with Swiss law and venue, and I found no public information on the application's own subprocessors such as the SMS gateway or email delivery — Zendesk is named only for the vendor's support pages, where the privacy policy says it is not used for the application itself. 7 6 2 4 5
The Salon Owner
The vendor's own pages state hosting in Frankfurt am Main in a C5-certified data center, processing within the EU, and a data processing agreement under Article 28 GDPR that can be signed electronically in the backend. The contracting entity is eTermin GmbH in Schwyz, Switzerland, and of the chain only Zendesk (US, for the vendor's own support pages, stated as not used for the application) and Tapfiliate (Netherlands, partner program) are named. I found no public information on the SMS or email delivery providers behind booking confirmations, nor on ISO 27001 or SOC 2 certification. 7 2 6 5 1
The Sales Team Lead
Hosting is documented as a C5-certified datacenter in Frankfurt am Main in Germany with the application operated inside the EU, a data processing agreement under Article 28 GDPR can be signed electronically, and configurable deletion and anonymisation options are published. The contracting entity is eTermin GmbH in Schwyz, Switzerland; the named subprocessors cover only the website — Zendesk in the US for support pages, which the privacy policy states is not used for the application itself, and Tapfiliate in the Netherlands for the partner program — and we found no public information on the application's own subprocessors for hosting, email or SMS. 2 4 5 6 7
The Independent Consultant
For my German, Austrian and Swiss clients this reads well: the vendor is a Swiss GmbH in Schwyz, the servers stand in a data centre in Frankfurt am Main certified under the German C5 catalogue, a data processing agreement under Article 28 can be signed electronically, and appointments and contacts can be deleted or anonymised on individually configurable schedules. The chain is thinner than it looks, though: the privacy policy names processors only for the vendor's own website (Zendesk in the US for support pages, Tapfiliate in the Netherlands), I found no public information on the application's own SMS gateway or email delivery providers, and the only certification stated is C5 for the data centre. 2 4 5 6 7
The Data Protection Officer
The contracting entity is named precisely — eTermin GmbH of Schwyz, Switzerland, with its registry number — hosting is stated to be in an EU datacenter at Frankfurt am Main with a C5-certified datacentre, a data processing agreement under Art. 28(3) GDPR is published and electronically signable, and configurable deletion or anonymisation of appointments and contacts is documented. But the chain I must sign off is not closed: we found no public list of the application's own subprocessors, so the hosting operator, the SMS gateway behind the reminders and the email delivery service are unnamed, and Zendesk is named only for the vendor's own support pages, where the privacy policy states these tools are not used for the eTermin application; we found no public information on ISO 27001 or SOC 2 certification for the vendor itself. 1 2 5 6 7
The Skeptic
Hosting is stated as a C5-certified datacenter in Frankfurt am Main in Germany, and a GDPR Article 28 data processing agreement can be signed electronically, but the contracting entity is eTermin GmbH in Schwyz under Swiss law and Swiss courts.

Pricing transparency
Show reasoningHide reasoning
How this is scored
Whether a buyer can compute the real annual cost from public pages alone: price per user, staff member, location or calendar, what the free plan covers, which features (SMS reminders, payments, round-robin, SSO, branding removal) sit in which tier, the cost of SMS credits and payment fees, setup and minimum term.
0 — No public prices at all; every customer is a sales call.
3 — A starting price or a free plan is published, but what scales the cost (users, staff, bookings, SMS) and what each tier includes is unclear.
5 — Tiers are public with their prices per user, staff member or location and their main features, while at least one commonly needed piece (SMS credits, payment fees, an enterprise tier) is unpriced or "on request".
8 — Every tier priced publicly with its scaling unit, add-ons and SMS credits priced, monthly and annual prices both shown, and VAT treatment and minimum term stated.
10 — Complete price computability: annual cost derivable for a given team size, location count and SMS volume, with every add-on, setup, support and payment fee and the cancellation and data-return terms published.
The Practice Owner
Lite at "€ 19 pro Monat" and Pro at "€ 29 pro Monat" are published with their main features and a comparison table, prices are stated to exclude VAT, the minimum term is three months with two weeks' notice, and annual billing gives one month free. But SMS, additional calendars, integrations and locations are named as add-ons without prices, Enterprise is an individual offer, and multi-location practices are told to ask for a quote. 1 3 6
The Salon Owner
Lite at € 19 and Pro at € 29 per month with a feature comparison, prices excluding VAT, a three-month minimum term renewing monthly, two weeks' notice, and one month free on annual billing are all public. But the add-ons — extra calendars, SMS, locations — carry no published prices, multiple locations go to a custom quote, and Enterprise is priced on request, so the real annual cost for eleven stylists across two salons is not derivable from the pages alone. 3 1 6

Lite at € 19 per month and Pro at € 29 per month are published with a feature comparison table, a thirty-day free trial without credit card, monthly and annual billing with one month free per year, prices plus statutory VAT, a three-month minimum term and two weeks' notice. Enterprise is priced on request, multi-location setups are individual quotes, and we found no public information on the cost of additional calendars, SMS credits, integrations, locations or payment fees. 1 3 6
The Independent Consultant
Lite at € 19 and Pro at € 29 per month are published with feature lists and a comparison table, VAT is stated as excluded, the minimum term is three months, annual billing gives one month free, and there is a 30-day trial without a credit card — so I can roughly see my cost. But I cannot compute it: extra calendars, SMS, integrations and locations are add-ons for which I found no prices, Enterprise is "PREIS AUF ANFRAGE", and I found no statement of what the monthly price scales with. The captured pages also give different cancellation details — "Jederzeit kündbar" on the pricing page against a two-calendar-week notice period in the terms. 1 3 6 15
The Data Protection Officer
The packages are public — Lite at € 19 pro Monat and Pro at € 29 pro Monat, both monthly and annual billing with one month free annually, prices stated excluding statutory VAT, a 3-month minimum term with two weeks' notice, and a feature comparison across tiers. A buyer still cannot compute the annual cost for a practice: SMS credits and the add-on prices for extra calendars, locations and integrations are not priced, and Enterprise is listed as "PREIS AUF ANFRAGE" with an individual offer for multiple locations. 1 3 6
The Skeptic
Lite at € 19 per month and Pro at € 29 per month are published with feature lists and a comparison table, together with VAT treatment, a 3-month minimum term with monthly renewal, two weeks' notice to month end, monthly and annual billing with one month free per year, and a 30-day trial without credit card. Enterprise is priced on request, the add-ons — further calendars, SMS, integrations, locations — are named but unpriced, and multiple locations or many calendars go to a custom quote, so a full annual cost cannot be computed from the public pages. 1 3 6

Where this could be wrong
- Evidence ages. The oldest capture behind this page is from 28 Oct 2026. Vendors change pricing and policies without notice; every fact reflects its source as of the capture date shown in the registry.
- Weak sourcing — Data processing agreement, Hosting location, Legal entity. Not confirmed on the vendor’s own pages as captured.
- AI can misread a source. Extraction and judgement are automated; a citation guarantees traceability, not infallibility. If something here is wrong, say so — no account needed, every report is decided within 5 business days, and accepted corrections are published.
