AI Receptionist Vendor Comparison: 12 Criteria That Matter Before the Demo
Every AI receptionist demo sounds great. The vendor answers your test call perfectly, the voice is natural, and the dashboard looks slick. Demos are staged, which is why the real comparison happens before you ever see one. Here are twelve criteria worth checking, in the order that matters.
1. What counts as a billed call or minute
The pricing page says “$99 a month for 100 calls.” The fine print decides what a call is. Do hang-ups on the greeting count? Do spam calls count? Do transfers count as one call or two? A plan that bills every connection is far more expensive than the headline suggests. Ask for the definition in writing before you compare prices.
2. Answer speed and concurrency
Ask how fast the agent picks up and how many simultaneous calls it handles. “Instant” and “unlimited” are the right answers. If the vendor hedges on either, your callers will hold during busy periods, which is the exact problem you are paying to solve.
3. Voice quality on real calls
Demo audio is recorded in a studio. Your callers dial from cars, job sites, and bad cell connections. Ask to hear recordings of real customer calls, not the demo reel. Listen for interruptions, background noise handling, and the pause between the caller finishing and the agent responding. Long pauses kill trust faster than any accent.
4. After-hours behavior
Confirm that after-hours calls get the full treatment: answering, qualifying, booking, not just message-taking. Some vendors downgrade to voicemail-with-transcription at night. You want the same agent at 2 a.m. that you get at 2 p.m.
5. Booking and calendar integration
Ask which calendars and booking systems connect natively, and what happens when the slot the caller wants is taken. A good agent offers alternatives and confirms in real time. A weak one “takes a request” that you have to sort out later. If your scheduling is complex, this single feature separates the usable from the useless.
6. Transfer and escalation rules
You will not let the AI handle everything, and it should not try. Ask how transfer rules are configured: which callers go to a human, how the handoff works, and whether the person picking up gets a summary of the conversation so far. Warm transfers with context are the difference between a system and a gimmick.
7. Spam and robocall handling
A meaningful share of inbound calls to small businesses is spam. Ask whether the plan filters robocalls automatically and, critically, whether filtered calls consume your allowance. Paying for a thousand spam calls a month is a quiet budget killer.
8. Call summaries and recordings
Every call should produce a short summary and, ideally, a recording with a transcript. Ask where they live, how long they are kept, who can access them, and whether you can search them. The summary is the whole point of the system for most owners: you should not have to listen to calls to know what happened.
9. Compliance posture
If you are in healthcare, ask about HIPAA-ready plans and a signed business associate agreement. If you take payments or collect sensitive data, ask about SOC 2 and how recordings are encrypted. Vendors in regulated industries should answer these without blinking. See the HIPAA vendor questions for clinics and what to ask about SOC 2 before you sign.
10. Setup effort and porting
Ask how long setup takes, who configures the greetings and rules, and how your existing business number moves over. Number porting should not cause downtime. If the vendor cannot explain the porting process clearly, that is a red flag about their operations generally.
11. Contract terms and exit
Month-to-month is the standard you should expect. Ask about setup fees, cancellation notice, and whether your call data and recordings are exportable if you leave. A vendor that makes leaving hard will make everything else hard too.
12. Support when something breaks
Ask who you talk to when a call goes wrong, and how fast they respond. Test it: email support with a real question during the trial and time the reply. Phone systems break at the worst moments, and the vendor’s support quality matters more than any feature on the list above.
How to use this list
Score two or three vendors on these twelve points in a simple spreadsheet before you book demos. The demos will all sound good; the spreadsheet keeps you honest. Our post-demo scorecard picks up where this leaves off, with a framework for comparing vendors side by side after you have seen them in action.
I write the agents that run on clinic phone lines and inboxes: the conversation engine and the booking logic behind them, plus the integrations with Pabau, Fresha and Phorest. Everything here comes out of systems we have actually shipped, not a content plan.
