Question
My service delivers sales leads to my clients. Is there any simple calculation for creating an estimated ROI if you don't know each of your client's internal costs per sale?
Answer
Have your client create it! Have an outline of the types of costs/time it saves your client and have your client tell you the numbers while you are meeting with him/her. It is believable because your client created it - very powerful tool! Contact me if you want to learn the method
