As answered by people managing StackGo and terminio.ai.
terminio.ai's answer:
Two things most scheduling tools don't do. Reminders go out over WhatsApp instead of email, which is where people in German-speaking Europe actually read messages. And an AI phone assistant answers incoming calls in natural German, checks live availability and books, reschedules or cancels the appointment — so a business doesn't lose a booking just because nobody could pick up.
terminio.ai's answer:
Most booking tools were built for people who sit at a desk. terminio.ai is built for businesses whose hands are busy while the phone rings. It combines four things that usually require separate tools: a booking page, WhatsApp reminders, deposits that reduce no-shows, and a phone assistant. Setup takes minutes, there is a free plan, and everything is hosted in the EU under GDPR.
terminio.ai's answer:
Small and medium sized service businesses in German-speaking Europe that work by appointment: hairdressers and beauty salons, car repair shops, driving schools, veterinary and medical practices, physiotherapists. Typically one to fifteen people, no dedicated reception, and no IT department.
terminio.ai's answer:
Small business owners kept describing the same two problems: the phone rings while their hands are busy, and a share of booked appointments never show up. Existing tools assumed a desk, an inbox and a customer who reads email. terminio.ai was built around what those businesses actually do — with WhatsApp as the reminder channel and an assistant that handles the calls nobody can take.
terminio.ai's answer:
TypeScript, React and TanStack Start on the frontend; Supabase (PostgreSQL) for data and authentication; Stripe for payments and deposits; the WhatsApp Business Platform for messaging; Capacitor for the native iOS and Android apps.
