Abstract: A method and system for managing inventory information by a host company forming an inventory based information network having multiple tiers of access with at least one host server and at least one remote company user. The host server has an interactive inventory listing, manages remote company user access to the inventory listings, and enables remote access to the host server for the remote company user to create and manage inventory listings. The interactive inventory listing builder creates a new inventory listing, generates an associated unique listing code, and adds a photo file and text data. The method generates interactive advertisements and websites. The interactive advertisement builder creates a new advertisement, chooses a target media outlet, inserts the inventory listing, and generates and saves advertisement. The interactive website builder allows a user to select a template, add object files, choose domain names, and save the website.
