You can use the ClubSpark Coaching App to register all you attendees and add any ‘walk ups’ who haven’t booked. All this is synced with your ClubSpark system to save you the admin.
Alternatively you can do this directly in ClubSpark admin area.
You will need to head to the class that you have run, where you will see a register of the participants. For each participant that attended the class, you will need to tick the 'Attended' box.
If a new participant joined the class that didn't book online. You can add them to the class via the admin area. Click Here on how to manually add a participant.
