BEVERAGE OR FOODSTUFF CONTAINER CONSUMPTION MONITORING METHOD

A method for monitoring beverage or foodstuff container consumption includes: deriving, at a beverage or foodstuff preparation machine, container consumption information; and updating, using the consumption information, stock state information. The stock state information contains information detailing an amount of containers at a location of the machine. The method also includes obtaining, at an electronic device external to the machine, the updated stock state information; and/or receiving, on the electronic device from a remote resource over a network, stock order information which includes information detailing an amount of containers purchased by a user. The method further includes updating the stock state information using the stock order information; and displaying, at the electronic device, the amount of stock derived from the updated stock state information.
