So What Is A Cleaning Audit? Well its not what you might think. Its a really cleaver way to conduct a sales interview with a prospects. You see by asking questions and letting the prospect talk will give them a much better inpression of you. sounds strange but it works. the key questions for me if you are going to have great working relationship is whats gone wrong in the past and hat are the OCD points for this person. what I mean by that get that one little thing wrong and nothing else you have done will matter. get it right and you both have a happy life.
