In the Customer screen, simply fill out customer details, including contact information, project location, and job number. On this screen you can also select which reports you would like to include in the final printout/email. After selecting “NEXT”, you will find the "How Much" section, where the customer can see precisely how their final cost will be calculated. Once you have discussed this information, select “NEXT” again view the Lifestyle screen. This screen reveals a quick customer survey which will later be used to recommend additional accessories.

Autodraw Instant Loads: Using the side menu to the right, set the number of floors to include in the calculation and hit the "Autodraw from ReDb" button to calculate an instant load calculation.

Manual Drawing: Using the map as a guide, simply tap the outline of the house to set your building footprint dimensions. If desired, the map feature can be turned off and a white grid will appear for a more free-handed approach.
