A mediation computer accepts service linkage request condition information, which indicates a service linkage condition and requests service linkage, from a first service providing computer and accepts service linkage permission condition information, which indicates a condition for permitting service linkage, from a second service providing computer. The mediation computer generates a linkage service list, which shows a combination of services that can be linked, on the basis of the accepted service linkage request condition information and service linkage permission condition information. It becomes possible to provide a user with linkage service including a plurality of combined services by which both of the user and the servicer can request merits.
