A management system includes an information processing apparatus that stores management information about cartridges that store consumables and is configured to update the stored management information, and an image forming apparatus configured to print an image on a sheet using the consumables stored in an attached cartridge, storing cartridge information about a cartridge that has been previously attached to the image forming apparatus, and configured to, when a cartridge is attached, retrieve cartridge information from the attached cartridge as first cartridge information and the stored cartridge information as second cartridge information, and transmit the first and second cartridge information to the processing apparatus. Upon receipt of the cartridge information, the processing apparatus determines whether the attached cartridge is a refilled cartridge, and if so, updates the management information so that the cartridge is identified as a refilled cartridge. The processing apparatus transmits a determination result to the image forming apparatus.
