Perfect Order Rate measures the percentage of orders delivered without any errors—meaning the right product, at the right time, in the right condition, with the correct documentation. It is a comprehensive KPI that reflects supply chain efficiency and customer satisfaction. Improving perfect order rate requires excellence across order entry, inventory management, warehousing, and logistics. High performance in this area reduces returns, enhances customer trust, and supports long-term profitability through better inventory planning and fulfillment precision.
