Make your individual salespeople hit a notable sales metric before providing them with business cards, or train them to never give out their card without requesting the consumer's information first. Instill in your staff the responsibility of making the call; otherwise you're just breeding clerks.
You Have Permission to Ask
Asking for a sale is almost always daunting for two reasons. First, most salespeople aren't taught how to properly handle rejection. Second, most salespeople overcomplicate the closing process. One book touts itself as being the only all-sales book ever to hit The New York Times Best Seller list. The book contains about 300 different closes. While some are quite good, how on earth can you expect anyone to remember 300 different closing techniques — not to mention the proper scenarios to use them.
