采购确认通常用英文称为 "Purchase Confirmation"。这是一种书面或口头的沟通方式，用于确认一项采购交易的细节，包括货物的数量、质量、交货期限、付款条件等。

一些英文例句及其中文翻译如下：

Can you please send me a purchase confirmation for the order I placed last week? (你能发给我上周下的订单的采购确认吗？)

We have received your purchase confirmation and will begin processing your order. (我们已收到您的采购确认，将开始处理您的订单。)

Please confirm the details of the purchase, including the quantity, price, and depvery date. (请确认采购的细节，包括数量、价格和交货日期。)

I confirm that the purchase has been completed according to the terms and conditions agreed upon. (我确认根据双方商定的条件完成了采购。)

希望这些例句能帮到您。
