I didn't find the time to write an introductory text for this content yet, sorry about that!
Why do customers hate salespeople? Disalignment. A truly great salesperson is a resource. They help you: They educate you on the product. They honestly answer your questions. They address your concerns, seemingly patiently. They help you pilot / test the product first, in a way that drives things forward without too much pressure. They push the learn, buy, deploy process along, but don’t pressure you to buy if you aren’t ready. They ensure you get a fair price.
