All Industries:
Events
Sports events, conferences, festivals, and workshops all face the same core problem: managing group registrations with strict capacity limits, all on non-recurring one-time schedules. You need to track attendees, prevent overbooking, and coordinate across multiple sessions or activities within a single event.
Group Registrations with Capacity Control
Events require group bookings. You set a maximum number of attendees per session, and customers book together in the same slot. Multiple attendees book one session, and the capacity counter tracks real-time availability.
- Max capacity per session — set limits per activity (100 people for a workshop, 500 for a keynote)
- Real-time availability — customers see remaining spots; capacity automatically prevents overbooking
- Multiple attendees per slot — one booking for a group, or individual registrations that share slots
- Revenue scaling — more attendees in the same time slot = higher revenue per hour
Festival example
You run an annual summer festival with 10 workshops, each limited to 30 people. Set each workshop as a bookable service with max capacity 30. Attendees pick which workshops to join. No double-booking. No manual seat tracking.
Group Appointments
Set capacity limits per session and manage multi-attendee registrations.
Allow multiple customers to book the same time slot for classes and events
One-Time Event Schedules
Conferences, festivals, and one-off workshops don't repeat weekly. You need to define availability for a specific date range, and Opencals handles that without requiring recurring schedules.
- Non-recurring schedules — set availability for specific dates only (March 15-17 for a conference)
- Seasonal events — summer festival dates, annual conferences, one-time workshops
- Multiple activities per event — define separate schedules for each session or venue
Flexible Scheduling
Set non-recurring schedules for specific event dates without worrying about weekly patterns.
Set up non-recurring schedules for seasonal services and time-bound activities
Hybrid Events: In-Person + Online
If you offer hybrid attendance (some attendees on-site, others joining via video), Opencals auto-generates meeting links for online attendees using Zoom or Google Meet. Each booking gets its own link automatically.
- Automatic Zoom/Google Meet links — one link per booking, sent to customers and staff
- In-person or online locations — define physical venues and online meeting locations separately
- Google Calendar sync — your event coordinators' calendars stay in sync; existing events block booking slots
Note
You host a 3-day conference. Day 1 keynote is in-person (capacity 500); breakout workshops are hybrid (capacity 50 per breakout). Opencals handles both location types with automatic meeting links for remote attendees.
