Abstract
A cartridge providing system includes a printer ejecting a liquid (recording material) supplied from a cartridge, and a server managing provision of the cartridge to users that use the printer. Based on user stock data of each of the users, the server determines whether an unused stock, which is a stock that remains unused for a first period or longer from a start of holding, is present in a stock of the cartridges held by each of the users. If it is determined that an unused stock is present in the stock held by a first user, when a period until a usage expiry date of the unused stock is less than a first threshold value, the server sets a collection recommendation flag to the unused stock in the user stock data of the first user, the collection recommendation flag indicating the cartridge recommended for collection.
