The whole platform

Nine parts of your clinic, working as one.

No more juggling a booking app here, a spreadsheet there, and messages somewhere else again. Everything talks to everything, so you spend your time with clients, not chasing your own tools.

Online booking

A booking page that fills your diary while you sleep.

Give your clients a beautiful page to request an appointment, day or night, and pop the same booking widget straight onto your own website. It shows the next available slots first, takes a deposit if you want one, and never double-books you. You approve each booking in one tap.

  • Your own booking page, plus a widget for your website
  • Next-available slots shown first, mobile-first throughout
  • Take deposits at the point of booking
  • Different services for each of your locations

Calendar and diary

See your whole day at a glance, and move it with a drag.

Your diary, the way you think about it. Drag-and-drop appointments, see every practitioner and room side by side, and block out the time you need. When you grow into more than one location, it all stays in one calm view.

  • Drag-and-drop to reschedule in a moment
  • Multiple practitioners and rooms, side by side
  • Set each practitioner's working hours, including alternating week A and week B rotas
  • Block out lunch, training or time off in seconds
  • Multi-location ready as your clinic grows

Yes, properly. Your patients, appointments and history come across with you, carefully checked, so nothing is lost and you do not have to start from scratch. We stay alongside you until it feels like home.

No. CallidusOS is made for busy clinic owners, not techies, so everything is clear and gentle to use. If you ever get stuck, a real person is here to help, and most clinics are up and running in a day.

All of them. CallidusOS works beautifully on your computer, your tablet and your phone, with nothing to install. Open it in your browser and it is the same calm, clear platform wherever you are.
