Selling on target to control the sales interview. Know your company, the features and benefits you offer customers. The connotation in the words "canned presentation" is negative. Yet - you must have a track to run on, a path to follow so that when the prospect interrupts with a question you are able to respond and smoothly regain control. Then you can head in the right direction - to the close and another sales. One key to more sales is the ability to maintain or regain control of the sales process. Know the services you offer and develop how your services will benefit your prospect.
