Which side of the river is a required field, not a nice-to-have
If your CRM does not record state and county on every inquiry, every number downstream is a guess.
Jefferson County, Oldham County, Bullitt County and the Southern Indiana counties across the river behave differently on close rate, drive time and job size. A metro average hides all of it.
Routing depends on it too. Which estimator, which day, what you can promise on scheduling. A dispatcher guessing from a phone number is guessing.
Put the address question immediately after the name in the intake script. The address settles the state, the county, the drive and half the qualification.
If you are not set up to work Indiana, say so within the first thirty seconds and refer the caller to somebody who is. That call costs you a minute. A canceled appointment in Clarksville costs a half day and a review.
