The term for the time between placing an order and receiving it is lead time.
In supply-chain management, lead time measures the elapsed period from when a customer or purchasing department places an order to when the goods are delivered or ready for use. It can include several stages: paperwork and planning, supplier processing or manufacturing, dispatch, transportation, inspection, and put-away. The exact endpoint depends on the organization’s convention.
Lead time is not necessarily the same as transit or delivery time. Transit time covers movement after dispatch, while lead time may begin before production or shipment starts. Processing time usually refers only to work performed on the order, and cycle time generally describes the duration of a complete process or production cycle. Those terms can overlap in particular industries, but lead time is the standard answer for an order-to-receipt question.
Businesses track lead time because it affects inventory decisions and customer service. Longer or less predictable lead times often require more safety stock. Manufacturing planners may also distinguish supplier lead time, production lead time, order lead time, and total lead time when identifying where delays occur.
