How many times have you told a customer that you could not help them. Come on! I tell at least 2 people a day that they are not a good fit for my companies program but I can give them advice on what to do to help themselves in the future. Sometimes good, professional, and honest advice is the best thing you can give a customer. You may be able to possibly send them to someone who can help them and return them back to you as a qualified customer or even gain a good referral source. Keep in mind that one of the best things you can do in sales is learn how to say "NO" without saying "NO"!
