Event booking system
for workshops and seminars.
Sell out a workshop, cap attendance at a seminar, or manage sign-ups for a recurring class — with a capacity limit that closes registration automatically.
Built for workshops, seminars & classes
Take sign-ups without spreadsheets
A capacity limit, an automatic cut-off, and reminders — everything a one-off or recurring event needs.
Attendee capacity limits
Set a maximum number of attendees — registration closes automatically the moment your event is full.
One-off or recurring events
Run a single workshop or a weekly recurring class from the same calendar, with independent capacity per session.
Automatic reminders
Reduce no-shows with confirmation and reminder messages sent automatically before the event.

Why organizers choose ISZ Booking
- No separate ticketing platform or per-ticket fee — sign-ups go straight to your own booking page.
- Cap each session's capacity independently, so a popular weekly class doesn't overflow while a quiet one stays open.
- Collect exactly the information you need at sign-up with a custom form — dietary needs, experience level, anything.
- Share the same event link everywhere — social media, email, or embedded on your own site.
Frequently asked questions
Does registration really stop automatically once an event is full?

Can I run a recurring weekly class instead of a one-time event?
Yes, recurring sessions are supported with capacity tracked separately for each date.
Can I collect custom information from attendees when they sign up?
Yes, the booking form is customizable — add any fields you need, required or optional.
