Frequently asked questions

The term attendee management refers to the entire journey of an attendee to an event. From the invitation to online registration to check-in at the event. Attendee management offers software and services for an optimal digital process.

Attendee management can often be very complex. Well thought-out processes and efficient tools make it easier for event planners to maintain an overview. All attendee and registration data is available in a central system in real time, making communication with guests much easier. At the event, good attendee management ensures that guests can check in quickly and smoothly.

GuestONE supports event agencies with advice and full service, even in the pitch and presentation phase. We advise you on the best procedures and processes, help with screenshots and mock-ups and, if desired, take over the complete participant management.

With GuestHub and Eventry, we offer companies two different solutions for perfect attendee management. GuestHub is the flexible modular system for large, complex or short-term individual projects. Eventry is the license solution for regular and recurring projects that are to be implemented in-house.

Our many years of experience and 20 permanent employees guarantee you professional implementation and support for your project, even when things have to be done quickly. As we develop 100% in-house, we offer maximum flexibility.

With our Eventry license system, we offer our customers a powerful platform for handling multiple and recurring events completely in-house. Of course, our support team will assist you with all questions relating to the use of the system.

We do not plan your entire event, but we are happy to take over the entire participant management for you. Graphics and design, sending out invitations, providing flexible online portals and registering guests at the event are all part of our range of services.
