无意中看到了这个老外的建议，觉得对我们这些做外贸的朋友来说很实用，所以贴在这里跟大家一起分享！
As a sourcing agent and buyer I can tell you what is a good quotation for me:it includes all relevant information ! My job is to find a reliable supplier at a reasonable price in the shortest time possible.
It is very possible that I will choose a supplier whose price is a few percent higher but the quotation is complete. That means, it includes: - FOB (!!!) price, with seaport marked! (I often get FOB quotes without location. Obviously for me in Europe a FOB Shanghai price is higher than a FOB Xiamen price, since shipping rates are different).
- delivery time (so far no Chinese supplier was able to keep the promised delivery time for my projects - 90% delay, 0% early)
- package unit (carton details)!!! Carton weight, size, volume, content, material. It is very important!!! Usually this point is simply left out by suppliers. But I - and most full-time buyers - have just simply no time to beg for any details separately!!! If a quotation misses this, I simply delete it. I have no time to ask for these points, but I can only calculate my shipping cost with this info!!!
- payment conditions must be exactly discussed.
I hope suppliers will consider these points in the future. If you include all relevant information, you can really help your partner in his decision. And for the supplier, it is a job done once, you needn"t work out each detail separately.

辛苦楼主，谢谢！

学习，学习，谢谢！

很好，我以前做得不够啊。尤其是包装信息没有。

身為一名採購,我可以告訴你們,我認為的好報價:包含所有相關信息！我的工作職責就是以最快的速度尋找一個可靠的供應商，拿到合理的價格.

在很大程度上,我會選擇那種能提供完整的報價的供應商,哪怕他的價格高幾個百分點.所謂完整的報價包括:

含出港港口的FOB價(我經常收到一些沒有標明FOB港口的報價,很明顯對於在歐洲的我而言,由於海運費率不同,FOB上海的價格會高過FOB廈門.)

到貨時間(迄今為止,沒有哪個中國供應商對我們的項目做到他們承諾的到貨時間, 90%延遲,0%早到.)

包裝(外箱明細)!!!外箱重量,尺寸,體積,容量,材料,這些都非常重要!!!常常被供應商們遺漏掉了.但我-以及多數全職採購們-都簡直沒時間去請求他們做細節上的分類!!! 如果報價單中沒有這些,我就直接刪除.我沒時間去逐點問詢,卻只能依據這些信息去計算我的船運費.

付款條件一定要經過正確討論過.

我希望供應商以後能考慮這幾點.如果你們提供了所有相關信息,真的很能幫助到你們的合作夥伴作決定.於供應商而言,這只是一次性的工作,你不需要分門別類地去作出每項細節.

恩 值得收藏的一篇文章！我参加过展销会！我们的报价极为不合理！都是手工报价！可见级别太不一样了！

对这些建议非常有同感，谢谢楼主推荐！！

Good information for me`
