AI receptionist vs answering service: how to choose
An answering service is people paid by the minute. An AI receptionist is software paid by the month. Published prices from both, the volume where the maths flips, and the calls you should still want a human on.

Two things get sold as "we will answer your phone", and they are not the same product. One is people. One is software. They are priced on different units, they fail in different ways, and the choice between them is mostly a question about your own call volume and what you want to happen after the call is answered.
This compares the two as categories. Prices quoted below come from each vendor's own published pricing page, linked, and checked on 30 October 2026. They move, so treat the link as the authority and the number as the date it was read.
The real difference is what happens after "hello"
An answering service answers, takes a message, and passes it on. A good one feels like a professional extension of your front desk. What it generally cannot do is reach into your systems: the person answering does not have your calendar open with your buffers and your staff rotas in it, so the output is a message for somebody at your end to action.
Software can. Not all of it does, which is the single most useful question to ask a vendor, but an AI receptionist that is wired into your booking system can take the call and finish the job: find the real slot, hold it, and have the appointment in your diary before the caller has hung up.
That is the difference that matters more than the voice.
How each one is priced
This is where the decision usually gets made, so here are the published numbers.
People are billed by the time or by the call.
| Service | Published plan | Price | Works out at |
|---|---|---|---|
| Ruby | 50 receptionist minutes a month | $250 / month | $5.00 a minute |
| Ruby | 100 minutes | $395 / month | $3.95 a minute |
| Ruby | 200 minutes | $720 / month | $3.60 a minute |
| Ruby | 500 minutes | $1,725 / month | $3.45 a minute |
| Smith.ai | 30 calls a month | $300 / month | $10.00 a call |
| Smith.ai | 90 calls | $810 / month | $9.00 a call |
| Smith.ai | 300 calls | $2,100 / month | $7.00 a call |
Both pages read 30 October 2026. The right-hand column is our arithmetic on their numbers, not a rate either company advertises. Ruby's page notes that the only difference between its plans is the number of minutes, so the features are the same on all four. Smith.ai publishes overage rates above the included calls, from $11.50 a call on the smallest plan down to $8.50 on the largest.
The shape is the thing to notice. Both get cheaper per unit as you buy more, and both still cost more in total the busier you get. That is correct and fair: you are buying somebody's time, and a busy month is more of it.
Software is billed by the month, usually per location. Ours is: four tiers plus a negotiated Enterprise one, each with its included usage and the per-unit rate past it written out on the pricing page. The figures live there and only there, because that page reads the live price list and a number copied into a guide would go stale silently. The shape is the part that matters for this comparison: a busy month costs the same as a quiet one until you pass the included amounts.
Most of the big local platforms publish nothing. Checked on 30 October 2026: Podium shows no prices and asks you to talk to sales, Birdeye shows a form that wants your email and your number of locations before it will quote, and Weave publishes "starting from $199 per month" and puts a Get Pricing button on each tier.
You will find third-party blogs quoting what those platforms supposedly charge. We are not going to repeat those numbers here, because they are reports about somebody else's price rather than that company's own published figure, and we would want the same courtesy. Ask the vendor, in writing, and ask what it is per: per location, per user, per call, or per minute.
Where the per-minute maths flips
Take a single-location practice taking 120 calls a month, averaging three minutes each. That is 360 minutes.
On published per-minute pricing that is past the 200 minute plan, so you are into the next one up. On published per-call pricing, 120 calls is past the 90 call plan. On a flat monthly subscription, 120 calls and 1,200 calls cost the same.
Run it the other way and the answer reverses. A consultancy taking eight calls a month will pay less for a small human plan than for most software, and get a better answer on every one of those eight calls.
So the honest rule is: the fewer and the more valuable your calls, the better people look. The more numerous and the more repetitive, the better software looks. Nobody can tell you which you are without your call count, and your phone bill has it.
Side by side
| Answering service | AI receptionist | |
|---|---|---|
| Who answers | A trained person | Software |
| Billed on | Minutes or calls | A flat month, usually per location |
| Cost as you get busier | Rises | Flat until you pass the included usage |
| Hours | Often around the clock, because shifts are staffed | Around the clock, because nothing sleeps |
| Two calls at once | Depends on who is free | Both, every time |
| Channels | The phone | Phone, text, web chat and email, if the vendor does them |
| What you get back | A message to action | A message, and sometimes the appointment already booked |
| Where the record goes | Email, a portal, sometimes your CRM | Your own CRM, if it is the same product |
| Judgment on a hard call | Yes, a person is there | No, and it should hand over |
| Gets it wrong by | Mishearing, or not knowing your business | Answering confidently from the wrong information |
What an answering service is genuinely better at
This is the part a software company is tempted to skip.
A caller who is upset. Distress needs a person. Software can detect the words and hand over, which is the right behaviour, but the handover is still to a human being and a service already has one on the line.
The unscripted judgment call. "My mother was seen yesterday and something is not right" is not a booking request or an FAQ. It needs somebody who can decide what to do.
A caller who will not talk to a machine. Some will not, and no amount of product design changes that. If a meaningful share of your customers are in that group, that is a real reason to keep people answering.
Taking responsibility. A person can say "I will make sure somebody calls you back by four" and own it. Software can create a task. These are not the same promise.
What software is genuinely better at
Everything that is not the phone. This is the biggest practical gap, and it is usually missed in the comparison because the category is named after phones. Most enquiries now arrive as a text, a web chat or a form, and an answering service does not touch those. Our own shared inbox treats a call, a text, a web chat and an email as one thread per customer.
The same question, for the twentieth time today. Do you take my insurance, are you open Saturday, where do I park, how much is a new patient visit. Paying a per-minute rate for these is the clearest waste in the whole category.
Booking, properly. Not a message saying the caller wants Tuesday, but the appointment in the diary, against the right staff member, at the right length, with your buffers respected. See bookings for how availability is computed rather than guessed.
Being three places at once at 7am. Volume peaks do not queue.
Keeping the record. Every call, text and chat on one customer timeline, which is what makes the follow-up possible at all.
The hybrid most people actually want
Software takes the predictable volume and the bookings. A person, yours or a service's, takes what it hands over. The test of a good AI receptionist is not how much it handles, it is how cleanly it gives up: whether it hands over on the first ask, whether an urgent call is recognised and routed, and whether the person who picks up can see what was already said.
That last one is the practical argument for the phone and the texts living in the same product. A handover to somebody who has to ask the caller to start again is not much of a handover.
What Frontiva does today, plainly
Frontiva answers text, web chat and email, and answers the phone in a conversation: it can book an appointment on the call, move one, or cancel one, from the same approved facts it answers a text from, with the call transcribed into your inbox. Every guardrail that applies to a text applies to a call, so an urgent or medical call hears what to do and is put through to a person, and asking for a human works the first time.
Two things are yours to provide. The phone half needs a voice-capable number on your own Twilio account, connected under Integrations, and Answer calls with AI switched on for that location. It is off until you switch it on. The integrations page says what every connection needs from you and what it still cannot do, in both directions.
What Frontiva is not is a service with people in it. If what you need is somebody to take responsibility for a hard call, you need a person, whether that is your own or somebody you pay by the minute.
How to compare two quotes without being misled
- Ask what the price is per. Per location, per user, per call, per minute, per month. Two numbers on different units are not comparable.
- Ask what happens when you are busy. Get the overage rate in writing, and multiply it by your worst month rather than your average one.
- Ask whether it books, and against what. Your live calendar, or an export of it. Only one of those is safe.
- Ask what it does with the other channels. If it only answers the phone, price the rest separately, because the rest is most of it.
- Test the handover before you sign. Say "I want to speak to a person" and see what happens. Then describe an emergency and see what happens.
- Ask where the record ends up. A message in an inbox nobody reads is a call you paid for twice.
