How to Choose an AI Receptionist: A Practical Checklist for Small Businesses

Updated 2026-10-17. Prices come from vendor pages; see each vendor profile for sources.

An AI receptionist answers your business line, deals with routine questions, takes messages, books appointments and hands off to a person when needed. Entry plans now start at around $25–$100 a month. Here's how to choose one without regretting it three months later.

1. Measure your calls first

Pull a month of call logs: number of calls, average length, busiest hours and the share after hours. 200 calls at 2 minutes each is 400 minutes. That figure decides which plan fits and which pricing model works out cheapest.

2. Match the pricing model to your calls

• Per-minute bundles suit steady volume with short calls. Rosie's Professional plan is $49/mo for 250 minutes; Phonely Starter is $50/mo for 200 minutes.
• Per-call plans suit fewer, longer calls. Upfirst starts at $24.95/mo for 30 calls; Smith.ai is about $2.00 per call on Pro.
• Per-caller plans suit repeat callers. Goodcall counts unique customers, from $79/mo.

Check what happens when you go over: some vendors publish overage rates, and others don't. Our calculator marks plans without a public overage rate as "capped".

3. List must-have tasks

• Calendar booking with your actual scheduling tool
• Warm transfer to a mobile phone or team line, and when it should happen
• Text follow-ups (SMS) after the call
• Spam call filtering
• Keeping your existing number: call forwarding versus porting
• Bilingual callers

4. Compliance

If you're a US healthcare provider handling patient information, you need a vendor that signs a BAA. Some vendors say so on their pricing pages (Phonely on higher tiers, Lindy with a signed BAA). If a page doesn't mention it, ask in writing. For legal, financial or other regulated calls, check recording-consent rules in your state.

5. Setup effort

No-code receptionists can be live in minutes: you give them your website and FAQs. Developer platforms such as Vapi, Retell and Bland offer more control but need someone technical. Managed vendors set everything up for you, at enterprise prices.

6. Test before you commit

Most vendors offer a free plan, a trial or credits. Run the same ten test calls on your top two or three:

1. An FAQ ("Are you open Saturday?")
2. A booking request with a scheduling conflict
3. An angry caller who wants a human
4. A caller who interrupts mid-sentence
5. A spam or robocall
6. A question the agent shouldn't answer (pricing exceptions, medical advice)
7. A noisy line or a heavy accent
8. A caller switching language
9. A wrong number
10. A request to leave a message for a specific person

Score each on accuracy, tone, speed and whether it hands off correctly. Then use the matchmaker to make sure you haven't missed a good option.
