An order supporting apparatus connected to a monitoring apparatus over a network, the monitoring apparatus determining a supply status of devices in the network and sends supply shortage information regarding at least one of the devices determined to have a supply shortage to the order supporting apparatus. In particular, the order supporting apparatus includes a device information storage part that stores device information describing whether each device is monitored as a monitoring target, and maintenance contract information of each device, and a determination part that determines, based on the device information, whether each device is subject to the maintenance contract when the order supporting apparatus receives the supply shortage information. Further, the determination part deselects, in the device information, a device as the monitoring target when the device is determined to have a supply shortage by the monitoring apparatus.
