The biggest failing of the EOQ model is it assumes production costs and storage costs for your product are constant. Every time you place a purchase order, you have to pay the item manufacturer for your goods. But increasing your ordering cost by ordering more products at a time may allow you to enjoy a quantity discount (lower cost-per-item). Then, once you’ve received your products, you have to pay to store those products. Economic order quantity (EOQ) is a replenishment model designed to help you minimize your inventory costs, and overall, improve your inventory and supply chain management.
When a business orders less inventory than its customers demand, it can easily lose out on customers who will go elsewhere for the product.
