Abstract: A system and method for monitoring the amount of alcoholic beverages dispensed from bottles in a business establishment that serves alcoholic beverages. The system and method uses a pair of scales located on opposite ends of at least one shelf upon which are positioned bottles of alcoholic beverages. The scales detect changes in weight on the shelf and provide that data, along with calibration data, to a system database and a processor which analyzes all that data to detect a change of weight of the shelf as well as position on that shelf of where that change of weight occurred. A point of sale system of the business establishment is also in communication with the system database/processor so that change of weight data, position data and sales data can be analyzed to display revenue and cost data on a computer including a software application that configures the computer for displaying spreadsheets of all of this data.
