Ask which city the address sits in, because Austin is often the wrong answer
The first call should establish jurisdiction, not just a name and a phone number, since the permit path and the promises you can make change with it.
Mailing addresses hide real boundaries. A house with an Austin address may sit inside West Lake Hills or Bee Cave, or in unincorporated Travis County, and further out you are in Williamson or Hays county rules entirely.
Add jurisdiction as a required CRM field on the first call. It routes the job, sets the permit expectation and tells your estimator what not to promise on the porch.
The same field handles the utility question. Program and rebate eligibility depends on which utility serves that address, and Austin Energy being municipally owned means most statewide Texas advice does not apply inside the city. Tell the caller you will confirm rather than guessing.
Capture the age of the house and the opening count in the same two minutes. Three fields sort a stuck patio door from a sixteen opening job before anyone commits a morning.
