CallidusOS™ vs Pabau

How we compare to Pabau.

A long-established UK clinic management platform used across aesthetics, medical, dental and wellness.

Pabau is one of the most established clinic CRMs in the UK and is used across many sectors. It's a mature, feature-rich platform with a large customer base. We respect what they've built. CallidusOS™ is a newer, modern alternative built around an integrated AI layer (Calia AI), CQC-aligned governance as a default, and an explicitly opinionated workflow for UK private clinics.

Where CallidusOS™ shines

  • Calia AI is built in: dictation, summaries, facial mapping, smart stock, campaign automation
  • CQC-aligned governance, audit trails and incident reporting are baked in, not bolt-ons
  • An integrated Leads CRM, marketing campaigns and clinic website service in one subscription
  • Modern, fast UI built on current frameworks
  • Transparent published pricing, no sales-led demos to see numbers

Where Pabau shines

  • Mature feature set built up over many years
  • Large established customer base across multiple verticals
  • Wide range of integrations and templates

Pabau might be a better fit if

  • You need a deeply established product with thousands of clinic deployments today
  • Your clinic already runs on Pabau and migration cost outweighs the benefit
  • You operate in a niche we don't yet cover

We try to be straight about this. The right software is the software that fits your clinic. If Pabauis a better fit, we'd rather you choose them than churn off us in six months.
