Abstract: Provided herein are systems and methods for management of event attendance packages and event attendance inventory. The systems and methods include instantiation of a plurality of inventory items relating to attendance of an event. One or more event attendance packages may then be built using the instantiated inventory items. Once an event package is approved, actual inventory items may be secured, and the inventory items may be allocated to a given package so that they are not available for use by other packages. The systems and methods herein may utilize various graphical user interfaces that enable building of virtual inventory, event package construction, actual inventory acquisition, and inventory/package allocation.
