I know that many novice businessmen have a problem in how to write a sales letter to another company, for example. Because in such cases it is important to be precise in wording, brevity and so on. So I recommend here to read a sales pitch [article](https://getprospect.com/blog/what-is-a-sales-pitch) and I think it will be useful for you too. Because I remember at first I was afraid of making a mistake when I was inexperienced. But it's very easy to explain here. Good luck, I hope it helped.
