In the accounting management system, the mobile terminal owned by the contractant being the management side can freely set the approval/refusal of the use of the mobile terminals used by the one or more non-contractants on the side to be managed and can prevent the mobile terminal used by the one or more non-contractants on the side to be managed from being excessively used.
