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