Since you already have a human admin on the phones, the part worth adding is a simple missed-call text-back habit that runs alongside her, not instead of her. The real win is not the automation itself — it's that a caller who hung up gets a reply from your company before they dial the next number.
Two practical rules that keep the text-back from feeling like a form letter. First, let it land a minute after the call drops so it reads like your admin saw a missed ring and typed back, rather than something firing the instant the phone stops. Second, keep the opening to a sentence that names the company and asks one question: "Hey, this is your company name. We just missed you — what can we help with today?" Anything longer gets deleted; the goal is to make the homeowner tap back, which hands you the conversation.
The piece that trips most offices up is the hand-off. When the homeowner replies, your admin needs to see it the same way she sees an inbound call — a notification she can open and carry on in, with the phone number and the original reason visible at the top. Build a one-line intake she copies into her system the moment she jumps in: name, service, address, urgency, best number. If the hand-off works and she responds inside ten minutes on a weekday, a missed-call text-back quietly saves a job a month without changing how she does her job during the day.
