The ease of use, the ability to manage all aspects of an event from start to finish. We've been able to deliver successful events that are managed by our own team without the need for costly external help. Nothing in particular, but this is an excellent product and I highly recommend it. In some parts of Europe, there can be some slight language differences when sending out invitations or even the confirmation emails. It doesn't take too much effort to get them to understand what you're trying to say. The benefits far outweigh any issues we've had with the software. Manage all aspects of an event and improve efficiencies.
