SOLUTION: When a service A by a desired service provider is accompanied by the use of an accounting service by an accounting service provider, a service- A acting object and an accounting service acting object are obtained first (S301, S302). Then client information is set and held for the obtained accounting service acting object (S303) and transferred to the service-A provider through the service-A acting object (S304).
