20 years Lexus and Harley-Davison.NEVER leave a message of any kind ,only talk with the decision maker(s). Always ask are all the decision makers present? Follow up until you get a yes or no. If you say you will call back on a certain day or time...do it! This shows you can deliver satisfaction. Some customers want to control the sale, some want to be sold. (Regardless you must be in control of the sale)Phone cold calling is the hardest lead to control, before you tell the cold call what you are calling for introduce yourself, (not your company yet) ask them for their name, from this point of the call use their name in as many open ended questions as possible.(when was the last time you cleaned your roof) ...don't ask a question that no is a possible answer. Hope this helps just trying to give back to this site, I have taken a lot of info from here.
