I like and admire good sales people. I would even go so far as to say that I enjoy being sold to - when it's done well. Taking the time to understand me and my situation, my objectives, my likes and dislikes. Adding value to the purchasing process by overlaying technical expertise to help me refine my requirements. Being respectful of the competition and respectful of the constraints on my purchasing process that at times can make me appear to be a difficult buyer. This is what I like. I'm a sucker for a good, professional sales pitch.
Which is why I was so disappointed recently to come across one of the worst sales pitches I have ever witnessed from a company - a software vendor in the P2P space - who really should have known better.
