"订货至交货的时间" can be translated into English as "lead time" or "order-to-delivery time".
"Lead time" is a commonly used term in business and supply chain management, referring to the time interval between the initiation of an order and its final delivery.
"Order-to-delivery time" is a more straightforward and descriptive translation, clearly indicating the time span from placing an order to receiving the goods.
Both expressions are accurate and appropriate, depending on the context and the level of specificity required.
