## 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.

## Scores by judge and criterion

Scores out of 5, each judge scoring independently against the published rubric (v1). "n/r" = not rated: the vendor publishes no price, or the judge found no public information on that criterion.

### The judges

- **The Practice Owner** (v1.0): Runs a physiotherapy practice with six therapists, two treatment rooms that must not be double-booked, and a front desk that spends its mornings on the phone. Wants patients to book and reschedule online, SMS reminders that cut the no-shows, rooms and therapists checked together, and patient data that stays in Europe under a data processing agreement the practice can show.
- **The Salon Owner** (v1.0): Owns two hair and beauty salons with eleven stylists and a Saturday that is booked out by Wednesday. Wants every service with its own duration and price on one booking page, clients who pick their stylist, a deposit for colour appointments, a fee when someone does not show, and a monthly bill that does not grow with every chair.
- **The Sales Team Lead** (v1.0): Leads fourteen account executives in three time zones and gets every demo request from the website. Wants inbound demos routed by company size and region, round-robin that is fair and can be checked, two-way sync with Outlook and Google so nobody is double-booked, a video link in every invite, and the booking written into the CRM before the call starts.
- **The Independent Consultant** (v1.0): Sells coaching sessions and workshop days on her own and books clients from Germany, Austria and Switzerland. Wants a booking page that looks like her own website, payment taken when the session is booked, a buffer after every call, her private calendar respected, reminders she never has to send herself, and a price that makes sense for one person.
- **The Data Protection Officer** (v1.0): Signs off booking tools for a group of medical and legal practices, where an appointment alone reveals who is a patient or a client. Wants the contracting entity and hosting named, every subprocessor listed down to the SMS gateway and the email service, calendar access limited to what booking needs, and bookings and customer records that can be exported and deleted on request.
- **The Skeptic** (v1.0): Has seen "free forever" booking pages that put the vendor's logo in front of every client, SMS reminders that turn out to be credits sold separately, round-robin and payments locked in the top tier, and calendar sync that reads far more than free and busy. Reads the price list for what scales per seat, the subprocessor list for where the reminders are sent from, and asks how the bookings get out again.
