A controlling device for a multi-function device may acquire specific function information for a specific service providing server from a first storage unit, and acquire specific use information for a specific user from a second storage unit. The controlling device may determine, by using the specific function information and the specific use information, whether or not a usable function exists. The controlling device may execute a process for the multi-function device to receive a service related to the usable function from the specific service providing server in a case where it is determined that the usable function exists, and execute a process for prohibiting the multi-function device to receive a service from the specific service providing server in a second case where h is determined that the usable function does not exist.
