Information of a user group used to distribute the execution result of a job of an image forming apparatus is held in a memory. The execution result of the job appended with result appropriating destination information required to specify a user group to which the execution result of the job is to be appropriated is received from the image forming apparatus. The execution result of the job is distributed to at least one user group specified by the result appropriating destination information appended to the received execution result of the job. Billing management of job execution associated with a plurality of groups can be adequately made.
