The system includes an apparatus which automatically measures an inventory of a consumable good and tracks the inventory as it is used. The system may include a signaling device which creates a signal when a defined minimum amount of the consumable good has been reached. The apparatus may also send the user an electronic message that the defined minimum has been reached. The system may then automatically submit an order to a supplier for a replacement supply of the consumable good. This system may be used to track supply and reorder animal food, food staples, production supplies, manufacturing parts, or virtually any consumable good. Accordingly, a user may avoid the inconvenience and loss of time and money due to failure to timely replace a consumable good.
