Do you know the most common objections you hear? If you are listening well, and customer focussed, you should be able to recite them now. Chances are there will only be three or four.
Know it or not, you will have an answer or response that you will usually give to each objection. Consider also what the responses are. Now, give detailed attention to both what is causing the objection, and how you can improve your response.
Improvement will come from using better questions, not better answers. You will reduce the number of objections, and when they do arise, you will resolve them sooner.
Objections give you the opportunity to learn and improve. Take it.
