What CallidusOS is
CallidusOS is a web platform that combines bookings, patient records, CQC governance, and invoicing for UK aesthetics clinics. Clients can request appointments around the clock, and staff can approve bookings with one tap. Records may include treatment history, before-and-after photos, signed consent, consultation notes, and face maps. The platform supports card payments, deposits, card-on-file, branded invoices, and PDF receipts; digital card payments incur a 0.1% platform fee plus Stripe processing fees. Connections are described for QuickBooks, Xero, and Mailchimp, with a webhook/API key for website leads. Both plans list multi-factor authentication, encrypted data, patient audit trails, and secure UK hosting. CallidusOS says data is private to the clinic, exportable, and handled in line with GDPR. It works on computers, tablets, and phones without installation. Growing costs £18 a month for up to 150 patients; Established costs £50 a month with unlimited patients and multi-location support. A 14-day trial is available, but there is no free plan.
