I like that it is very easy to use, allows multiple ways of payment options (website or credit card), has integrated google drive so we can upload our file easily! Sometimes takes too long between adding new guests vs actually having them come in but this could be because i am working from home which maybe makes things more difficult (not something specific just an observation). We have about 500 guest registrants each year at conferences around North America - some big, others small with different levels/types of attendance & costs associated - the conferencenet system enables us to get these numbers up quickly without manually collecting payments by hand afterwards using Excel data entry after every event. I like that it's easy to create different options, such as payment plans or late registrations. It is very easy to use once you get familiar with how it works. The support team is extremely helpful when needed! Nothing at this time. We are currently using their service because we have several recurring meetings throughout our year (we run multiple workshops each month). This makes scheduling everything much easier than if we were doing them ourselves separately.
