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.
