The Challenge
Traditional on-site queues led to crowded waiting rooms, unrest, and no transparency about wait times — especially when multiple locations or teams needed to be coordinated at once.
SmartWaiting
Digital queue management for medical practices, public offices and service providers – SmartWaiting replaces the physical queue with a smart, multi-tenant system.

Our Solution
We built SmartWaiting, a multi-tenant SaaS platform: guests join the digital queue via QR code, public link or directly through WhatsApp, staff call the next number with a click, and admins manage multiple waiting rooms, teams and licenses centrally from a dashboard.
Key Features
- Join the queue via QR code, link or WhatsApp – no app required
- Automatic WhatsApp notification with reply options "I'm coming" / "Can't make it"
- Live queue view for staff with a call-next function
- Four roles – admin, manager, worker, guest – with distinct permissions
- Manage multiple waiting rooms and locations centrally from the dashboard
- Premium: prioritisation, treatment-room assignment, staff-assisted queueing
- Link external booking calendars (e.g. Calendly, Doctolib, Google Calendar)
- Multilingual (German/English) with PayPal-based license management
