6. Forget about clichés. Kowal does not advise starting a conversation with a "How are you doing today?" This phrase is unoriginal, and everyone prepares to put up a defense against a sales call. However, Kowal suggests trying "Can you spare a minute?"

7. Go the extra mile for business beyone the call. Closing is not the only objective of a sales call. "Sometimes, moving the relationship along a step so you can be closer to closing on the next call is a better approach than trying to close right away," says Kowal.

8. Learn to listen. Don't be in too much of a hurry to get through your message that the customer is not able to get in one word. Even though you are working from a script, a sales call is a conversation, not word-for-word. Kowal encourages scripts, or call outlines, that interact with the customer and gives them the chance to speak more often. The more you lean about the customer's needs, the more things you'll find they are interested in buying.
