CV VLJ is a distributor of mineral water and bottled water in Cilegon area, Indonesia selling various water brands and is supplied by four suppliers. CV VLJ often runs out of goods in the warehouse when consumers want to buy the goods they are looking for. As a result, consumers are disappointed and buy it at other distributors. This leads to lost sales. Therefore, this study aims to reduce the loss of sales and minimize the total inventory cost at each supplier. The determination of the order quantity and period is calculated using the EOQ, POQ, EOQ multi-item and multi-item EOI methods. The inventory total cost and lost sales can be calculated through the inventory table simulation. Based on the simulation results, sales losses can decrease by 88-99% for all four suppliers and total costs decrease by an average of around 33% compared to actual conditions.
