外贸单证制作精要

所谓从上到下，即从一张单据的最上面的项目开始，做完上一行的项目再做下一行的项目，遇到一行有多个纵向项目，则要遵循从左到右的原则。这样，一不容易把需要改动的项目漏改；二把整张单据划分成单元小块完成制作可以提高精确度。

Foreign trade documents to make the essence

The so-called top-down, that is, starting from the top item of a document, finishing the item on the previous line and then doing the item on the next line. When there are multiple vertical items in a line, the principle of left-to-right should be followed. In this way, it is not easy to change the items that need to be changed; Second, the whole document can be divided into small pieces to improve the accuracy.

因为我们在做单据时，每个公司都有其一套固定格式，通常每次都会套用固定格式，但在套用的同时容易出现“应该修改的项目而没有改过来”的错误。比如同一种商品不同订单批次的出口单据，往往套用相同格式、抬头、品名的单据，但由于是不同批次订单的票据在日期，数量，和编号等小方面有细微的差别，这些差别很容易被忽略。然而，只要奉行从上到下，从左到右的原则来制作单据，并在这个原则下切实做到“心想口读眼盯笔点尺比逐行逐字母一一核对”基本上就可以避免这方面的错误。

When we make documents, every company has a set of fixed format. Usually, the fixed format is applied every time. However, when applying the fixed format, it is easy to make the mistake of "the items that should be modified but not changed". For example, export documents of different order batches of the same commodity often apply the same format, title and name of the documents, but because the documents of different batches of orders have slight differences in date, quantity, number and other small aspects, these differences are easy to be ignored. However, this error can be largely avoided by following a top-down, left-to-right approach to document making, and by following the principle of "thinking like reading with your eyes fixed on the pen dot scale rather than checking it line by line, letter by letter".

前面是做单据的基本思路，但具体怎么做是非常灵活多变的，要视不同业务的具体情况而定。外贸单据是记录整笔外贸业务的见证，应该与合同和实际相符合。在非信用证业务项下的单据虽然没有在信用证项下的单据要

求严格，但也要求正确、准确、精确。

Before is the basic idea that makes bill, but specific how to do is very flexible, want to depend on the specific circumstance of different business and decide. Foreign trade documents are the witness to record the whole foreign trade business, should be consistent with the contract and reality. Documents not under a credit although not under a credit

To be strict, but also to be correct, accurate and precise.
