AI receptionists for small businesses: how they work and how to set one up
An AI receptionist answers your business line, handles common questions, books appointments into your calendar and sends you a summary of every call, while passing urgent or unusual calls to a person.
For many local businesses, the phone is still where the money comes from. And every call that goes to voicemail is a customer deciding whether to try someone else.
What it can do
- Answer every call, including nights, weekends and the lunch rush.
- Answer common questions: hours, prices, service area, what to bring.
- Book, move or cancel appointments in your real calendar.
- Take a detailed message and text or email it to you right away.
- Transfer urgent calls to a person, using rules you set.
What it shouldn't do
It shouldn't make promises you haven't approved, quote prices outside your rules, or handle anything sensitive like medical details or legal advice. Good setups are clear about what the AI owns and when it hands off.
Set it up
- Write your top 20 questions. Listen to a week of calls or ask whoever answers the phone. Write the question and the answer you want given.
- Decide the hand-off rules. Which calls go straight to a person? Emergencies, angry customers, big jobs, anyone who asks for a human.
- Connect your calendar. The receptionist needs real availability, or it will book times you can't keep.
- Forward overflow first. Start with calls you'd miss anyway: after hours and when the line is busy. Expand once it's working.
- Review a week of calls. Read the summaries, fix wrong answers and add missing questions. Most of the quality comes from this step.
Tell callers they're speaking with an AI assistant. People mostly care about getting a fast answer and a booked time.
