A business unit R sells a plant raising printer 400 for raising plants to a user by using H20 generated by a fuel battery in driving the printer. The user raises plants by support of the plant raising printer 400. The printer provides the raised plants to a predetermined contract agent which has made a contract with the business unit R. The contract agent which has received the provision of the plants registers information related with the provision action to a distribution management server 100 of the business unit R by using the agent terminal 200. In executing business by using the provided plants, the contract agent registers information associated with the business in the distribution management server 100 by using the agent terminal 200. The distribution management server 100 applies points to the user and the contract agent based on the registered information.
