Detailed Review
Ordinus is a scheduling service run from Hagen in Germany under the trade name of a sole proprietor, Marcel Kremer. Its application, database and backups sit with Hetzner in Germany, and the terms put Ordinus in the processor role for client data under a built-in data processing agreement. The product covers the usual booking-link basics: event types, calendar sync, reminders, payments through your own Stripe account and an embeddable widget.
What it adds over a plain booking link is routing. Round-robin, shared pools and collective events arrive on the Team plan at €39 a month for up to five members, and the roadmap aims at capacity and territory rules for larger sales and service teams. That makes it a fit for small teams that want leads distributed between colleagues without a CRM.
It is also very new and run by one person. Nothing on the site shows a founding year, a certification or a customer count, and the Operations plan, AI Copilot and SMS add-ons are labelled coming soon. Established tools further up this page offer deeper integrations, multi-location booking and a longer track record, so Ordinus suits you if routing matters more than maturity.
What Ordinus does well
- Hosted in Germany on Hetzner with backups kept in the EU
- Round-robin and pooled team scheduling from €39 a month for five members
- Free plan with no credit card, plus a flat yearly discount of 20%
- Payments go straight to your own Stripe account, so funds never pass through Ordinus
- Data processing agreement included in the terms and a countersigned copy on request
Where Ordinus falls short
- Run by a sole proprietor, so there is no company behind the product and no stated continuity plan
- Short integration list: Google Calendar, Outlook, Google Meet, Stripe and webhooks
- No security certification is claimed on the site
- Operations plan, AI Copilot and SMS credits are still marked coming soon
Standout feature. It is a German-hosted booking tool that builds team routing into a €39 plan, though it is still a young one-person product.
