对询函的肯定答复可以给询问者一个肯定的信息，如接受订货要求、提供所需信息或是和新公司建立贸易上的往来。如果询函来自一家未曾有过业务联系的公司，一个肯定的答复还应表示出合作的意向，甚至可能促成一笔交易。

肯定答复可不是一句“Yes, we can do it.”就可以的，还应该提供一些强调产品或服务的重要信息。下面是一些肯定答复的写作注意事项：

1. Answer promptly, directly, clearly and accurately.
2. Emphasis one or two positive features of your product or service.
3. Choose words and a tone that convince reader to act.
4. Include a sales appeal for the product or service, and build goodwill through the whole letter.
5. End courteously.
