Abstract: A network 3 is used to connect a terminal (5) of a customer (9), a member store server (7) and a service provision server (8) of a member store (11), and a service surrogate server (13) with each other. An administrator of the member store (11) accesses the service surrogate server (13) to enter a reservation target resource, etc. The reservation target resource etc. are registered to the service surrogate server (13). The service surrogate server (13) also generates a time-based reservation screen (607). When the customer (9) applies for a reservation via the member store (11), the time-based reservation screen (607) is displayed. The customer (9) uses the time-based reservation screen (607) to make a reservation. Consequently, the present invention can provide a surrogate system etc. without necessitating the member store etc. to build a reservation system etc. for electronic business transaction using the Internet, etc.
