Quantore is the largest supplier of office equipment in the Benelux. Quantore keeps 15,000 items in stock for more than 500 retailers. It receives 11,000 order lines per day and processes 400 despatched consignments; too much to control manually. Slim4 uses sophisticated statistic methods to calculate reliable sale forecasts, requiring only analysts to check the exceptions. Following the installation of Slim4 the stock has decreased, and the service level to the customers has increased simultaneously.
