In my neck of the woods, reps are taking calls for quotes usually while sitting in traffic. They already know typical costs for typical products and price accordingly by the square foot, linear foot, install rate, design fee, etc. The question becomes; “When do you need it?” There is never a rush charge because the word is taboo. 3 choices of price are quoted by time frame, much like FedEx. Of the 3 price choices, urgency suddenly becomes not so urgent after all. Also, the verbal phone quote is a firm quote, not just an estimate. A Filemaker mobile app form is then sent to the caller as a more formal quote record.
So, the software is really just the computational processor of the rep’s noggin.
