Missed-call text-back does exactly what it sounds like: when a call to your business number goes unanswered, the caller automatically gets a text within seconds - something like "Sorry I missed you, I'm on a job, I'll call you back within the hour." It costs the caller nothing and takes zero effort on your part once it's set up.
The effect is bigger than it sounds. A homeowner who gets no response assumes you're unreliable or too busy and calls the next name on the list. A homeowner who gets an instant, human-sounding text knows someone's actually there - and is far more likely to wait for the callback instead of moving on.
It's live within 48 hours of setup, requires no change to how you take calls day to day, and typically pays for itself the first time it saves a single job that would otherwise have gone quiet.
