This is a book for people working (or wish to work) in B2B Sales. It is not really a book on HOW to sell, nor on HOW to create clients or close dealss, but more on what is needed to understand to be in this sector (regardless of industry).

I am not sure it will age well, as it is full of advise on current technological tricks (SalesForce, Zoho, etc.), but in general, I really liked it. As the author says in the beginning, there are a lack of MBA courses on sales, and this book may be a good starting point, to learn the vocabulary and the basic knowledge so that you don't look like an idiot the first time you encounter more seasoned sales persons.

In short, I rather liked it, as a starting point.
