What are you organising?
Slotr is one tool that takes the shape of whatever you need. Pick your situation and see exactly what your attendees see.
Every council asks something different. So just ask it.
Dietary wishes, which council member, staying for dinner or not. You set up the fields you need and get the answers back in one tidy overview. No email threads, no separate spreadsheet.
- Custom fields
- Waitlist
- Excel export
- GDPR-proof
Two hundred parents, two evenings, zero phone calls.
Set up the time slots once and let parents pick for themselves. Double bookings cannot happen, because a booked slot disappears from everyone's screen straight away.
- Time slots
- Multiple days
- Automatic reminder
- Reschedule themselves
Recurring shifts that fill themselves.
Plan the shifts once and add the names you already know. Those are shown for information and do not count towards capacity. Everyone else sees at a glance where a gap is left, and fills it themselves.
- Multiple time slots
- Already scheduled names
- Reminder beforehand
- Cancel by email
A cancellation is no longer a problem, just a hand-over.
When it is full, the page keeps working. Whoever cancels automatically makes room for the next person on the waitlist, message included. Even when someone brings a plus one, because the waitlist moves up by party size.
- Waitlist
- Automatic promotion
- Multiple people per registration
- Your own branding
Everything together, and one click to Excel.
Filter by event or status, search by name, edit details or resend a confirmation. And when the caterer wants a list, the Excel button hands over every registration including the answers to your own fields.
- All events in one place
- Filter and search
- Excel export
- Co-organisers
