This intuitive sales tool can be mastered in minutes and help differentiate you from your competition when utilized appropriately as part of an integrated Buyer Guidance (Sales) Process. This is a critical step in the Buyer Guidance Process that over 80% of all salespeople fail to do.

The process can be performed remotely to estimate the load and then trued-up once in the home.
