The first stage in setting up sales funnel reporting is to understand your sales process fully (perhaps using a technique like flowcharting). While sales processes are often quite similar from company-to-company, there can be points of difference depending, for example, on the size of the order and the consequences to the client of making the wrong purchase decision.
There’s a better solution: Build out an automated email follow-up campaign that speaks directly to this objection. Any time you encounter this problem, you can send that prospect information that seems designed just for them. A multi-month educational campaign may reduce their content anxiety and nurture them toward a sale. Yes, it’s work up front, but once finished, this campaign will work for you always.
