To provide a sales management system for new game software that serves to promote the sales of new software by making users feel attracted more to the new software than to used software.

A game information storage media 2 stores a first game program to be sold, data on privileges (second game program, specific character, specific item, etc.) provided as bonuses to each purchaser of new software, and a media identification code. For the user who purchases the new storage media 2 to use the media, an application password is issued on the basis of the media identification code and the hardware identification code of a game machine 3 to which the storage media is applied. When the user registers the application password in a customer management device 5 such as a server and if media identification data are yet to be registered, benefit permission data that authorizes the use of the benefit data is given. When the permission data is inputted to the game machine and the granting of the benefit data is selected, a process for granting the benefit data as benefits resulting from the purchase of the new software is performed to grant the benefits.
