Frequently asked questions
Is this a ready multi-tenant SaaS?
Multievent-planner is a web app deployed for your event or organisation. For hosting, customisation and go-live, contact Louis Thissen.
Do people need a mobile app?
No. Guest and admin areas work in the browser. Login and attendance QR codes are generated locally.
Can it handle paid activities?
Yes: each activity can have a price; the balance adds up fees and entered or imported payments.
How do you limit who can join what?
Through reusable conditions (age, tags, acknowledgements, etc.) and seat quotas, with slot closing.
Is there a real-world example?
Yes — digitising registrations for a pedagogical week is documented on Louis Thissen’s website. Read the case study.
