When you receive a call from a prospective client who is seeking information about your product, do you talk or do you listen? Do you start telling them about your offerings, or do you ask them questions?
A client of mine brought this up to me and it really is key. When someone calls you, you are given an opportunity to win them over. How? By asking them questions. You want to find out from them what they are looking for; what they are needing before you start telling them about your company.
Once you've learned about their needs, you can tailor your answer to those needs. It will sound like you have a customized solution to their specific problem. Not a 'one size fits all' solution.
Now you are a problem solver. Congratulations!
