一揽子采购协议Blanket Purchase Agreement，简称BPA的中文意思为“一揽子采购协议”，是一种为降低采购成本，与供应商签订的中长期采购协议。一次签订，多次要货。（一般中国企业都有中长期采购协议，但不习惯叫做“一揽子采购协议”）。一揽子采购协议通常持续时间长（6到12个月），谈判确定一段时间内的采购总量。由于采购数量大，可取得较低单价的优惠。一般随时需要，随时向供应商要货，只要在协议签订的时间范围内向供应商采购到合同规定的数量/总金额即可。具体看一揽子采购协议有以下的好处：通过谈判确定价格；便于满足不断重复出现的需求；减少重复订购、结算过程中的成本；通过长期大批量的采购，获得低价优惠；简化下采购订单的流程；便于达成双方合作共赢的条款；加大要货频率，减少单次采购的数量，灵活对应客户需求变化；数量、价格相对稳定，便于供应链双方预测供应与需求等。为了更好的理解该词，以下是其英文释义：A blanket order, blanket purchase agreement or call-off order is a purchase order which a customer places with its supplier to allow multiple delivery dates over a period of time, often negotiated to take advantage of predetermined pricing. It is normally used when there is a recurring need for expendable goods. Blanket orders are often used when a customer buys large quantities and has obtained special discounts. Based on the blanket order, sales orders ('blanket releases' or 'release orders') and invoice items can be created as needed until the contract is fulfilled, the end of the order period is reached or a pre-determined maximum order value is reached.

双语例句：

（1）If the Order is a “blanket purchase order”, then the Order shall constitute a non-binding forecast only, and seller is authorized to ship if and only when purchaser issues a release referencing the blanket purchase order number. No terms or conditions of sale proposed by Supplier that deviate from or supplement the provisions contained herein are accepted by the Purchaser and any such proposed terms and conditions are deemed to be excluded and null and void.

如果订单是“综合采购订单”，则该订单仅构成无约束力的预测，且仅当买方发出引用综合采购订单编号的发货通知时，卖方才有权发货。买方不接受供应商提出的任何偏离或补充本条件中规定的销售条款或条件，且任何该等拟议条款和条件均被视为特此排除并无效。
