A homeowner wants a heater replaced. You quote a range, name a brand, promise "sometime Thursday." You're driving; none of it gets written down.
At a new account you walk the equipment pad narrating into your phone: valve positions, a cracked lid, the gate code. That voice memo is the only record of the site.
"You said the heater install included the pad." Did you? With the call transcribed, you search "pad," read the exact sentence with its timestamp, and settle it in one text message instead of eating a $400 job.
