The customer solicitation support system includes: a portable apparatus carried by a customer; a plurality of client computers installed in shops; and a server for exchanging information among the plurality of client computers. The server manages desired product information, which indicates a product desired by a customer in association with customer information of each customer, and stocked product information, which indicates stocked products of each shop, in a database in association with shop information. When the customer goes around shops carrying the portable apparatus, the customer information is sent to the server from the portable apparatus of the customer via the client computer wirelessly communicating with the portable apparatus. The server having received the customer information compares the desired product information associated with the received customer information and the stocked product information, and sends information on shops holding the desired product to the portable apparatus of the customer via the client computer communicating with the portable apparatus.
