Therefore, to help you decide if Corsizio is the right solution for your event needs, please read the intended use for Corsizio to learn how it differs from other event registration software services.
How is Corsizio different from other online registration and payment services?
At Corsizio we firmly believe that the best results come from using the right tool for the job. There are many online registration and payment services available to you today, but they do not all operate in the same way or offer the same features, value, pricing, or user experience and satisfaction. There are also different services for different types of events. For example, concerts and festivals require a different event registration and payment approach than courses and classes. The former events benefit from a ticketing service provider, which Corsizio is not. We specialize in educational events, which necessitate a certain degree of attendee data and record keeping. On Corsizio, everything revolves around your events, and your attendees do not create their own accounts.
Corsizio uses leading-edge technology and provides a modern, attractive, easy-to-use service and user interface. It is an ultra-quick and responsive service, which also uses real-time technology for instant updates when new registrations or payments come in. Some similar services have been around for decades and in turn, may use outdated technology, have a cumbersome user interface, or are simply complicated to use and require timely technical support. We also have the most competitive and optimized pay-per-use pricing in the industry.
Finally, Corsizio uses Stripe to enable you to accept payments directly into any personal or business account. Also, unlike other services, Corsizio does not hold your money in an escrow account or until the event is over. You receive your funds right after the transactions have been processed on a 2 to 7-day rolling basis depending on your country and set preferences.
