A server apparatus, a method for controlling the server apparatus, and computer-executable process steps for causing a computer to perform the method, for constructing an on-line sales system appropriate for a creator and sells a commercial item including a content without imposing, on the creator, the workload involved in the construction and operation of the on-line sales system, and without the risk of stocking unsold commercial items. More specifically, a support server receives, from a creator terminal, information relating to the commercial item that is produced by outputting the content based on commercial item information, sets an address of a location of each commercial item on a network, and sends page data containing the address to an orderer terminal. Upon receiving location information represented by the address from the orderer terminal, the support server outputs a command to an output apparatus to produce the commercial item.
