You spend to make the phone ring, then the phone rings while the crew is loading a truck at 6pm. Most callers do not leave a voicemail and do not call twice — they call the next business on the list.
The expensive part already happened. Ranking, the ad click, the review that convinced them. Losing it at the last second is the most costly failure in local marketing and the cheapest one to fix.
An AI receptionist is not a phone tree. It answers in your business name, knows what you do and where, answers the price question, and books the slot — then hands you a summary by text.
