The booked site evaluation is the only inquiry that has ever paid you
A form fill is a hope, and a scheduled visit on a specific day is a project, so the entire intake should aim at converting one into the other on first contact.
Stop counting inquiries. Count booked evaluations, kept evaluations and signed agreements. Those three numbers tell you where the loss actually is, and they are usually the numbers nobody has.
Book on the first conversation whenever possible. Every hour between the inquiry and a date on the calendar increases the chance someone else gets there first, and in a market with this many new arrivals the buyer is calling several companies with no loyalty to any of them.
Give whoever answers the phone the authority and the calendar to book on the spot. Passing the lead to an estimator who calls back tomorrow is the single most common leak in this trade.
Then track the show rate. A confirmation the same day and a reminder the day before will do more for revenue than most website changes, because a missed visit costs you a slot and a competitor gets the yard.
