商务英语：reference customer —— 标杆客户要能被别人核对

reference customer：可以对外引用的标杆客户。对方知道你在用他们的名字，而且合作范围、是否付费能够被核对。它不是「我们认识一家大公司」。

We can name one reference customer, and they have paid for a 90-day pilot.

A strategic partnership is not a reference customer until the scope is written down.

Please do not put their logo on the deck if they have not approved the quote.

周六讲案例。地瓜的开发者数量、雅迪的换电网络、帧观德芯的贷款，都要能回答：谁可以替这句话作证。说不出证人，就还是故事。

用英语写两句：一句点出你的 reference customer 是谁；一句写明试点是否付费。第二句如果是 not yet，就不要在第一句里用 already。
