The Lost Art of Closing by Anthony Iannarino (Author)

For decades, sales managers, coaches, and authors talked about closing as the most essential, most difficult phase of selling. They invented pushy tricks for the final ask, from the “take delivery” close to the “now or never” close.
 
But these tactics often alienated customers, leading to fads for the “soft” close or even abandoning the idea of closing altogether. It sounded great in theory, but the results were often mixed or poor. That left a generation of salespeople wondering how they should think about closing, and what strategies would lead to the best possible outcomes.
