Fill Rate

Fill rate measures how well a supplier or warehouse satisfies orders as they come in. It can be expressed by units, order lines or complete orders — for example, an order fill rate is the share of orders delivered complete and on time. A high fill rate signals dependable supply; a low one points to stock or fulfilment problems.

For buyers, a supplier's fill rate is a key performance indicator captured on scorecards, because consistent complete deliveries reduce the need for chasing, part-shipments and emergency buys. It sits alongside on-time delivery as a core measure of fulfilment reliability.
