You have a quote in one tab and a competitor's pricing page in another, and the numbers refuse to line up. One vendor wants $460 a month for two hundred minutes. Another wants $810 a month for ninety calls. A third says it costs less than a receptionist. None of those sentences can be compared to the others as written, because this market bills on two different units. This page does the conversion, shows the division, and flags the one claim on a major vendor's pricing page that does not survive a check against federal wage data.
What this covers
Answering services and AI receptionists are not priced on the same unit, so until you convert them to a single unit you are not comparing anything. Ruby and PATLive bill on included minutes. Smith.ai bills on calls. A per-minute plan and a per-call plan can invert their ranking entirely depending on how long your calls run.
The conversion takes four minutes and one report from your phone system. Pull the last thirty days: total answered calls, and total talk minutes. Divide minutes by calls. That figure, your average call length, is the exchange rate between the two halves of this market.
Run that before you read another pricing page. The honest answer to "which is cheaper" depends on a number only you have.
A traditional answering service is a room of trained people who pick up your line under your business name, follow a script you wrote, and pass the result to you. An AI receptionist is software that answers the line, holds the conversation, and, if built properly, writes an appointment into a calendar.
Human services are genuinely good at things worth paying for. They handle the caller who is furious, grieving, or describing something the script never anticipated. They read tone. Bilingual coverage is usually a published add-on rather than a rebuild. Where calls are emotionally loaded or legally delicate, that judgment is a real product.
The limits are equally real. Human services are staffed, so cost scales with the minutes you consume, and your busiest hour is the hour staffing is hardest. Many operate on a message-taking model by default, so the deliverable is a notification rather than a booking.
An AI receptionist inverts the profile. It answers on the first ring at 2 a.m. on a Sunday with the patience it had at 10 a.m. on Tuesday, and it has no busiest hour. It carries your full service list, service area boundaries, and booking rules. It is weaker exactly where humans are strong: the genuinely unanticipated call, which a good build routes to a person instead of faking. We cover how these systems are assembled on our voice agents page, and keep a running comparison of the alternatives.
Here is what the three most-quoted vendors publish, from their own pricing pages. The effective per-minute and per-call columns are our arithmetic, not the vendors'. Each is the plan price divided by the included volume, with the division shown.
| Plan | Price | Minutes | Effective per minute (our math) |
|---|---|---|---|
| Starter | $250/mo | 50 | 250 / 50 = $5.00 |
| Professional | $395/mo | 100 | 395 / 100 = $3.95 |
| Business (marked Most Popular) | $720/mo | 200 | 720 / 200 = $3.60 |
| Enterprise | $1,725/mo | 500 | 1725 / 500 = $3.45 |
As published on ruby.com/pricing. Ruby states there are "no additional or hidden fees for activation, onboarding, setup, customization, or coverage during certain periods." The overage rate is not published there. Ask, because overage is where a minutes plan gets expensive.
| Plan | Price | Minutes | Effective per minute (our math) | Published overage |
|---|---|---|---|---|
| Basic (pay as you go) | $75/mo | none included | not applicable | $2.60/min |
| Starter | $250/mo | 75 | 250 / 75 = $3.33 | not published |
| Standard (marked Most Popular) | $460/mo | 200 | 460 / 200 = $2.30 | $2.20/min |
| Premium | $720/mo | 350 | 720 / 350 = $2.06 | $2.10/min |
| Pro | $1,170/mo | 600 | 1170 / 600 = $1.95 | not published |
As published on patlive.com/pricing. Add-ons: bilingual receptionists $20 per month, multiple scripts $20 per month each. Outbound calling is separate at $460 per month including 40 contacts, $12 per additional contact, plus a $250 setup fee. A 14-day free trial is offered on answering plans.
| Plan | Price | Calls | Effective per call (our math) | Overage | Free transfers |
|---|---|---|---|---|---|
| Starter | $300/mo | 30 | 300 / 30 = $10.00 | $11.50/call | 1 |
| Basic | $810/mo | 90 | 810 / 90 = $9.00 | $10.50/call | 2 |
| Pro | $2,100/mo | 300 | 2100 / 300 = $7.00 | $8.50/call | 10 |
| Enterprise | custom | high volume | not published | not published | not published |
As published on smith.ai/pricing. Add-ons include business caller ID for outbound at $10.00 per month and additional transfer destinations at $15.00 per month.
Ruby's cheapest published rate is $3.45 per minute. Smith.ai's cheapest is $7.00 per call. There is no honest way to say which is the better deal without knowing your call length.
Smith.ai's own pricing FAQ compares its top plan to hiring, and the number it implies sits roughly 47 percent above the federal mean wage for the job. The claim reads: "Even our most expensive plan, the pro plan, is about $33,000 less than the yearly salary of an in-house receptionist."
Smith.ai's Pro plan is $2,100 per month. Twelve months at that rate is 2,100 times 12, which is $25,200 per year. If that is $33,000 less than a receptionist's yearly salary, then the salary being referenced is 25,200 plus 33,000, which is $58,200.
Check that against the source of record. The Bureau of Labor Statistics survey for May 2025 puts the mean annual wage for receptionists at $39,460 and the median at $38,010, across national employment of 910,180. In Texas the mean is $35,720.
Implied salary in the vendor claim: $58,200. BLS mean annual wage for receptionists, May 2025: $39,460. Difference: $18,740, or about 47 percent above the federal mean.
Read this fairly, because the fair reading is more useful than the gotcha. $58,200 is entirely defensible as the fully loaded cost of an employee. An employer does not just pay wages. Payroll taxes sit on top, and so do benefits, paid time off, equipment, and the cost of replacing the person when they leave. Add those to a $39,460 wage and $58,200 is not outlandish.
The problem is the label. Fully loaded employer cost is not a salary, and the sentence says salary. Those are two numbers with two definitions, and the comparison shifts from generous to modest depending on which is used. Against the loaded figure the plan looks like a large saving. Against the wage line a receptionist would recognise as their salary, the same plan looks less dramatic. Nothing here is fabricated. The word is doing work the number cannot support.
When a vendor compares itself to hiring, find out which number they used. Ask whether the figure is wages only, or wages plus taxes, benefits, and overhead, and ask for the source. If the answer is a round number with no citation, treat the comparison as marketing rather than analysis. Run this check on our pages too. We would rather be checked than believed.
Per-call billing punishes short calls and per-minute billing punishes long ones, and which one is working against you depends on your call mix. Neither unit is dishonest.
Take the short-call business first. A trades contractor with quick inbound traffic might average 1.5 minutes. At 200 calls a month, that is 300 talk minutes. On a per-minute plan at $2.20, 300 times 2.20 is $660. On a per-call plan at $8.50, the same volume is 200 times 8.50, or $1,700. Two and a half times the bill, because the vendor charges the same for a 90-second call as for a nine-minute one.
Now invert it. A business with detailed intake might average 8 minutes. At 60 calls a month, that is 480 talk minutes. Per minute, 480 times 2.20 is $1,056. Per call, 60 times 8.50 is $510. The ranking has flipped, and nothing changed except the shape of the conversations.
A per-minute plan gives the vendor no reason to keep a call short, and Smith.ai says as much defending its own model: "Billing per client call saves you money, and there's no mystery accounting involved. You're trusting us to represent you. You wouldn't rush a client off the phone and we don't either." The counter-argument is equally real: per-call billing gives the vendor no reason to keep call counts down. Find the incentive before you sign, and read the overage rate more carefully than the headline.
For a dollar figure on what the unanswered calls are costing you before you shop at all, our missed call calculator runs that arithmetic on your own volume and job value.
None of the numbers above tell you the thing that decides the outcome: whether the service that answers can book the job. A message taken is not a job booked, and that gap is worth more than any per-minute difference on this page.
A caller reaches your answering service at 6:40 p.m. The service takes the details and sends them over. Now somebody on your side has to read it, call back, find a time, and confirm. That is a second conversation you pay for in labour, after the customer has gone back to a phone full of other options. A booking is a different object: the caller hears real availability, picks a slot, and the appointment lands on the calendar before the call ends.
Be fair about this: some human answering services do book appointments, and some AI receptionists do nothing but capture a name and a number. This is not humans against software. It is message-taking against booking.
Three questions settle it. Does it read my live calendar, so the hours it offers are hours it can fill? Does it create an actual appointment record, or a notification someone on my end has to action? Can it route by service area or service type, so the wrong job does not land on the wrong crew? Ask for a live demonstration into your real calendar before you sign. For trades specifically, we broke this down on our page for contractors.
One more thing that does not survive checking. The three statistics in almost every piece of marketing in this category, the share of voicemail callers who never call back, the share of buyers who go with whoever responds first, and the share of inbound calls businesses miss, we could not trace to a primary study we were able to read. So we are not publishing any of them. Your own call log is better evidence, and you already own it.
Inbound answering and outbound AI calling are two different compliance questions, and most buyers collapse them into one. The distinction turns on one word in the federal rule.
In February 2024 the FCC adopted a Declaratory Ruling that, in its own words, "recognizes calls made with AI-generated voices are 'artificial' under the Telephone Consumer Protection Act (TCPA)". It took effect immediately, and stated that the rules requiring "telemarketers to obtain prior express written consent from consumers before robocalling them" now hold "AI-generated voices in calls ... to those same standards."
Read alongside the underlying rule, the scope becomes clear. 47 CFR 64.1200 says no person or entity may "initiate any telephone call ... using an automatic telephone dialing system or an artificial or prerecorded voice" to a cellular number without prior express consent. Telemarketing with an artificial or prerecorded voice requires "prior express written consent of the called party". And the calling window, "before the hour of 8 a.m. or after 9 p.m." local time, attaches to any entity that shall "initiate any telephone solicitation" to a residential subscriber.
Every one of those prohibitions hangs on the word initiate. They govern calls a business places out. A customer who dials your number is not a call your business initiated, so the artificial-voice consent requirements and the 8 a.m. to 9 p.m. window are not the rules that govern an AI answering your inbound line.
Two caveats. This is a general description of a federal rule, not legal advice, so take a real opinion from a lawyer before you build an outbound programme. And "the outbound rules do not apply" is not the same as "you have no obligations". Call recording and disclosure requirements vary by state, and we will not characterise them without a verified citation. What we will tell you is our own practice: our agent discloses recording in its first words on every call.
We do not publish our monthly price, and the reason is not coyness. The build is scoped to your services, your service area, and your booking rules, and a number posted without that context would be a guess dressed up as a quote.
What we will state plainly, so you can hold us to it. Setup is $0. The term is a three month minimum, because a voice system needs a few weeks of real calls before it is tuned to how your customers talk. Every plan includes a block of minutes rather than unlimited minutes, and usage past that block is $0.50 per minute. We never quote unlimited minutes, because minutes cost real money. We pay for the minutes inside the block, so the quoted price is the price.
What the system does is verifiable on a call. It answers 24 hours a day, reads your real availability, writes a real appointment record rather than a notification for somebody to retype, routes by service area or service type, and discloses recording in its first words. We run our own front desk on it, so when it breaks we find out before you do.
One thing we will not promise is same-day text messaging. Two-way SMS requires per-client carrier registration under A2P 10DLC, and it turns on when the carriers approve the number.
Usually, but not automatically, and the honest answer depends on your volume and call length. Published human-service rates work out to roughly $3.45 to $5.00 per included minute at Ruby and $1.95 to $3.33 at PATLive, with Smith.ai charging $8.50 to $11.50 per call in overage. AI answering is generally priced below those rates. But a cheap line that fails to book the job costs more than a dearer one that books it, so compare on jobs scheduled.
Because each unit favours a different call mix. Per-minute billing rewards short calls. Per-call billing rewards long ones, since a 40-second call and an eight-minute call cost the same. Neither is comparable to the other until you convert.
Get your average call length from thirty days of your own call log: total talk minutes divided by total answered calls. Multiply a per-minute rate by that average to express it per call, or divide a per-call rate by it to express it per minute.
Some do and some only take a message, and that distinction matters more than the per-minute rate. Ask for a live demonstration of a booking into your actual calendar before you sign anything.
The federal robocall rules attach to calls a business initiates outward, and the FCC confirmed in February 2024 that AI-generated voices are artificial voices under the TCPA. A customer dialling in is not a call you initiated, so those consent rules and the 8 a.m. to 9 p.m. window are not what govern an inbound line. Outbound AI calling is a separate, stricter question. Not legal advice.
We could not trace them to a primary study we were able to read, so we do not publish them. Use your own call log instead.
