CallidusOS review
A broad web-based clinic system for booking, records, payments and marketing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CallidusOS is cloud-based clinic management software for UK aesthetic and medical aesthetic clinics. It brings online booking, calendar and diary management, patient records, treatment history, clinical notes, digital consent forms, payments, branded invoices, prescriptions, inventory, reports and marketing into one web-based system. It is aimed at smaller clinics and growing practices that want operational and treatment documentation tools in a single platform, with access through browsers on computers, tablets and phones.
The published plans show a 14-day trial and two paid tiers. Starter covers an online booking page and widget, calendar and diary tools, patient records, digital consent forms, payments, branded invoices and appointment reminders. Aesthetics costs £50 per month when billed monthly and adds email and SMS marketing, rebooking, win-back and birthday automations, face mapping and injection charts, prescription creation with prescriber sign-off, reports and insights, and multi-location readiness. This makes the plan structure easy to understand by capability: core clinic administration sits in Starter, while clinical mapping, marketing automation and broader operational reporting sit in Aesthetics.
Its main strength is breadth for clinics that need more than appointment scheduling. Patient histories and photos, treatment notes, consent, deposits, invoicing, prescriptions and stock-level tracking address several recurring workflows, while marketing automations support rebooking and patient outreach. The trade-off is that the platform is web-only and does not offer a free plan, so it is less suited to clinics seeking a free operating system or a non-browser application. Clinics wanting booking, documentation, payments and inventory together should consider CallidusOS; those needing a narrower scheduling tool or a broader platform fit should compare alternatives.
