In a server, a storage is configured to store status of a service agreement for delivering a cartridge with an image-recording device. For the image-recording device, the cartridge is available in a first mode and is unavailable in a second mode. The status includes a first status indicating that the service agreement has been in force and a second status indicating that the service agreement has been canceled. The storage is further configured to store instructions causing the server to receive a cancellation request of the service agreement from an information processor; transmit a switch command to switch an operating mode of the image-recording device from the first to second mode in response to the cancellation request; and change the status stored in the storage to the second status in response to receiving a response indicating that the operating mode has been switched from the first to second mode.
