Corsizio

Corsizio is a class, course and event registration platform designed for organisations that run scheduled sessions and need attendees to enrol and pay online without administrative overhead. It occupies a deliberately narrow niche: not a full learning management system, not a general appointment scheduler, but the registration and payment layer for in-person and online classes, workshops, camps and short courses. That focus is reflected in its pricing model, which charges a small fee per registration rather than a monthly subscription, so an organisation running occasional workshops pays only when it actually takes enrolments — a structure that suits seasonal and intermittent programmes far better than a fixed fee.

Event and class setup covers single sessions, multi-date series, recurring schedules, terms and multi-session courses, with capacity limits, waitlists, age or prerequisite restrictions, and early-bird or tiered pricing. Registration forms are configurable to collect the information a programme actually needs — participant details, emergency contacts, medical notes, dietary requirements, consent and waiver acceptance, custom questions — which removes the paper forms usually collected on the first day. Payment is taken at registration through integrated processors, with support for deposits, instalments, discount codes, coupons and refunds, and the option to offer free or invoice-based registration where payment happens offline. Automated confirmation emails, reminders and cancellation notices keep attendees informed, and attendee lists, check-in tools and rosters support running the session itself. Administrators manage registrations, transfers between sessions, cancellations and refunds, and export data for reporting or external systems. Embeddable listings and a public event page let registration sit on the organisation's own website. Typical users are independent instructors, studios, community education providers, camps, non-profits, professional training providers and workshop organisers. A free version and free trial are available, with per-registration pricing from around USD 0.15. Organisers pay only when registrations are taken, which suits irregular event schedules.
