A firm order is often called an indent, and there is a special type of commission agent called an indent house. 确定的订单常被称为订货单,而且有一种特殊的佣金代理商叫做进口订货行。
Make sure that the orders get off promptly. A buyer either places a closed indent, which names the supplier, or an open indent, which leaves the choice of supplier to the agent. 买方或提出闭口定货单,指定供货商;或提出开口订货,由代理商自己选择供货商。
