Fill rate refers to the percentage of orders or requests that are successfully fulfilled or completed by a company or organization. It is a measure of efficiency and customer satisfaction, as a high fill rate indicates that the company is able to meet the demand for its products or services in a timely and accurate manner. A low fill rate, on the other hand, may indicate issues with inventory management, supply chain, or customer service. In the world of e-commerce, fill rate is a crucial metric for measuring the success of online retailers in delivering orders to customers. Overall, a high fill rate is essential for maintaining a positive reputation and retaining loyal customers.
