The Online Order System (OOS) and the trade fair website (event portal) serve different purposes in the context of your trade fair participation:
Online Order System (OOS)
Used to order services and products related to the exhibition stand as well as for detailed stand planning – e.g. editing and uploading a stand sketch, accessing admission documents. Additional users can be invited and assigned individual access and ordering rights. Bank details, invoices, and other documents can also be centrally managed here.
Trade fair website
Provides access to the exhibitor dashboard, enables company presentation, marketing activities, visitor management, and networking opportunities.
