All exhibition organizers can be divided into those having material and technical basis (special exhibition areas, exhibition equipment, service conditions), the so-called exhibition centers, and those having no such basis.

Accordingly, exhibition centers must have staff to maintain such facilities, and other organizers (not exhibition centers) rent exhibition space and equipment, including from the exhibition centers. Under the contract of contract or contract of mandate, they can hire third-party organizations to perform both the entire set of works on the installation of equipment (stands), and its individual parts.

The product of the organizer is an exhibition or fair as a complex of services provided simultaneously to all consumers (exhibitors, visitors). With the same set of services provided by the organizers, but with different themes, organizational and technical measures taken at different stages of the exhibition (preparation, holding, closing), it (the exhibition or fair) will have its own cost price.

That is, each exhibition is a unique, one-of-a-kind product. Therefore, preparation for each next exhibition requires development of separate organizational, technical and financial plans.
