AI answering services for small businesses: real prices and a setup that won’t embarrass you

When it’s worth it

An AI receptionist answers when you can't: with a customer, in a session, on a job, driving or after hours. It takes the caller's details, answers basic questions from information you give it, and texts or emails you a summary. Better ones can book onto your calendar or transfer urgent calls to your cell.

It's worth paying for if calls regularly go to voicemail and those callers are new work. If you miss only a couple of calls a week, a clear voicemail greeting and a callback within the hour may be enough. Look at last month's call log before you decide.

What they cost

These four publish their prices. They bill in different units, so read the "includes" column carefully.

Decide what it covers

Most small businesses start with one of these:

• After hours only. Calls ring you during the day; nights and weekends go to the AI.
• Overflow. Calls ring you first and go to the AI if you don't answer within a few rings, using your carrier's conditional call forwarding (on no answer or busy).
• Everything. The AI answers every call and transfers the ones you want. This works best once you trust it.

Starting with after-hours or overflow means your existing customers barely notice, and you can listen to the first few weeks of calls before it handles more.

Write the script: what to collect, what never to say

Every service has a setup screen for this. Whatever the tool, give it the same three things.

1. What to collect from every new caller

• Name and callback number
• Whether they're a new or existing customer
• What they need, in their words
• How urgent it is, and by when they need an answer
• For visits to the customer, the address or at least the town

2. When to interrupt you

Define urgent plainly for your business: an active leak for a plumber, a same-day cancellation for a salon or clinic, a client with a deadline tomorrow for an accounting or law office. Have those transferred to your cell or texted to you immediately. Everything else becomes a summary you deal with later.

3. What it must never do

Never quote a price, a range or "it usually costs".
Never promise an arrival time or a start date. Say the owner will call back to schedule.
Never say we are licensed, insured or certified for something unless it is in the information I gave you.
If you don't know an answer, say you'll pass the question to the owner.
If the caller asks for a person, take a message and mark it urgent.

Test it like a customer would

1. Call it yourself 10 times as different customers: a clear job, a vague one, an angry one, an emergency, a spam caller and someone asking for a price.
2. Read every summary. Check whether you could call each person back and know what they wanted.
3. Fix the instructions where it rambled or guessed, then call again.
4. For the first month, read every call summary daily. After that, spot-check weekly.

The part no tool does for you

An AI receptionist only captures the lead. The job is won or lost on how fast you call back. Set a rule you'll actually keep, such as every summary answered by 8 p.m. the same day, and make the summary land somewhere you'll see it (a text beats an email for most owners).

If your phone is busy because email, quotes and follow-up eat your evenings, that's the bigger problem to fix. The ChatGPT setup guide covers part of it.
