It lists no routing forms, collective meetings, SSO or audit reports. | From its public pages, Cal.com gives the most for the money here: a usable free plan, team routing from $12 per user and audits in its own name. SSO and audit logs start on Organizations, text messages run on credits, and a few pages place HIPAA and EU hosting differently. | From its public pages, Calendly is a full-featured scheduler for sales and recruiting teams, with routing, round robin and CRM integrations on Teams and audits in its own name. It costs more per host than the other per-user tools here and offers no HIPAA BAA or EU hosting. | From its public pages, Zoho Bookings is the lowest-cost way here to give a 3-host team round robin and collective booking, with Zoho’s audits and EU hosting behind it. Payments, text messages, routing forms and the audit log sit on Premium, and the plan for SSO is not stated. |
