Ask for the address, because plenty of Clarksville callers say Louisville
People describe themselves as being in Louisville when they live across the river, and the whole job hangs on which state that address is in.
Clarksville, Jeffersonville and New Albany sit in Indiana and think of themselves as part of this metro, which is exactly right socially and completely wrong for your paperwork. Requirements around licensing, tax and registration generally differ by state, and it is worth confirming your own position with your counsel or insurer before you take work on the other side.
Make the street address the first or second thing intake captures, on the phone and in the form. City name alone will mislead you, and finding out at the site visit costs you a half day and a crew.
Route by state from that field. A Floyd County inquiry and an Oldham County inquiry may need different paperwork, different scheduling and sometimes a different answer entirely.
Also record the county on every inquiry, including the ones you decline. Louisville Metro and Jefferson County are a merged government while the surrounding counties are not, and process differs enough that the county belongs in your record from minute one.
