1. Open the class on the Calendar.
  2. In the Attendance column, mark each client:
    • Attended
    • No-show
    • Left during the class

If you want the professional to add a comment and the actual duration when taking attendance, turn on Ask for comment and duration when marking attendance in Advanced center settings.

Why taking attendance matters

  • It feeds the Attendance block on the Overview and the attendance statistics.
  • It can trigger CRM automations, such as a message when someone misses a class.
  • It helps you spot clients who are starting to drop off.

Note: marking No-show doesn't give the session back to the client. The session counts as used.
