Calendly vs OnceHub 2025: Simple vs Enterprise Scheduling

Calendly is perfect for simple 1:1 meetings – fast, reliable, everyone knows it. OnceHub (formerly ScheduleOnce) is the power tool for complex scenarios: panel meetings with multiple people, resource booking (rooms, equipment), and session packages. If you only book simple meetings, Calendly is more than enough. If you need to coordinate multiple people or manage resources like meeting rooms, you need OnceHub.
