The best answering service for small business, compared on the meter

First, the thing that actually decides your bill

Every provider on this list answers the phone. What separates a $50 month from a $500 month is the unit on the meter, and there are five of them in this table: per call, per minute, per interaction, per unique customer, and flat. They behave completely differently when your phone gets busy.

Per-call and per-minute meters are the traditional shape, and the human services all use one of them: PATLive at $2.99 a minute, Specialty Answering Service at $1.54, Ruby and Abby in bundles of receptionist minutes. Several of the AI vendors kept the same shape with a smaller number attached: Upfirst per call, Dialzara and Phonely per minute, Nextiva XBert per interaction. The property they share is that a busy month is an expensive month, in exact proportion to how busy it was.

Per-customer meters, which Goodcall and Vandial use, count people rather than conversations. A customer who rings four times about one job is one customer. The bill tracks the size of your book, not the weather. Flat meters, which SkipCalls and OnCallClerk publish at the very bottom of the market, do not count anything, which is either the best deal on the page or the reason to ask what happens when everyone signs up.

So the first question is not which vendor. It is: in your busiest week of the year, how many calls do you take, and would you rather that week cost the same as a quiet one or three times as much. Answer that and half of this list disappears.

Goodcall: cheapest published entry, and the same meter we use

$79 a month per agent, unlimited minutes, 100 unique customers included, $0.50 per customer after that; $129 for 250 customers on Growth and $249 on Scale. That is the lowest published entry price of anything on this list metered on customers, which is the unit that fits a service business best.

We are a competitor and it would be convenient to skip past this. It is $20 a month cheaper than our entry rung on a comparable meter, and a business with low volume and simple needs should look at it seriously. The Starter plan keeps call and customer detail for 7 days, allows one logic flow and three team members, which is where the constraint sits rather than in the price. If your intake is one script and you do not need last month's calls, that constraint will not bite.

Vandial: built for the week your phone does a month's work

$99, $349 and $899 a month, metered on unique customers with unlimited call flows and no per-call or per-minute charge. Spam and wrong numbers are zero-rated and never create a customer record, so the robocall that rings your line eleven times in a week costs you nothing.

What it is genuinely best at is volatility. In a trade with weather, seasonality or emergencies in it, such as plumbing, HVAC, roofing, restoration, fuel delivery or property management, the week that produces a third of your annual call volume is the week a per-call meter produces a bill you did not budget for. Here it produces the same bill as a quiet week.

The second thing is booking. It reads the capacity remaining in your Google, Outlook, Apple or CalDAV calendar and writes the appointment during the call, rather than emailing you a request or texting the caller a link. It also has a floor: it refuses to diagnose, refuses to price work nobody has seen, and has a configured sentence for each refusal, per trade.

Where it is not the answer: a business doing nine calls a month with no seasonality is paying for headroom it will not use, and Upfirst or Goodcall will cost it less. A practice that needs a signed BAA should not buy this. We hold no HIPAA certification and do not offer one; Phonely publishes a BAA on its enterprise tier and is the better place to look.

Upfirst and Rosie: the cheapest AI entries, on very different meters

Upfirst publishes the lowest AI entry price on this page: $24.95 a month for 30 calls, then $1.50 a call, with 90 calls for $59.95, 300 for $159.95 and 600 for $299, and 20% off for paying annually. For a business that takes a call a day and needs each one answered, screened and written up, the arithmetic is hard to beat. The meter is per call, so read the volatility paragraph above before choosing it for a trade with a season.

Rosie is $49 a month for 250 bundled minutes with message-taking limited to two scenarios and appointments handled by texting the caller a link. Booking directly into your calendar, warm transfers and texting during the call start at the $149 Scale tier with 1,000 minutes; $299 buys 2,000 minutes and a specialist to set you up. It trains itself from your Google profile and website, answers in English and Spanish, and ships iOS and Android apps. For a solo operator who mostly needs to know who called and why, the $49 tier is a fair price; a business that needs the phone to book should budget for Scale from the start.

Smith.ai: the easiest way to test the category at zero cost

Their AI plan includes 25 real calls a month free, then $3.00 a call, with a Pro tier at $150 a month for 75 calls at $2.00 each and an Enterprise tier at $500 for 300 calls at $1.67. Their human service is separate and starts at $300 a month for 30 calls.

The free tier is unusually generous by the standards of this market and includes recording, transcription, summaries, lead qualification, routing and scheduling through Calendly. If you are unsure whether an AI receptionist works for your callers at all, this is the cheapest way to find out with real customers.

The meter is per call, so the same caveat applies as to every per-call plan: your busiest month is your most expensive, and at $2 to $3 a call a trade's emergency week adds up quickly.

Nextiva XBert: worth it if you are already a Nextiva customer

$99 a month for 100 interactions, then $0.99 per interaction, sold as an add-on to a Nextiva phone plan rather than on its own. If your business phone system is already Nextiva, this is the shortest path to AI answering with no second vendor and no forwarding rules.

If it is not, the add-on framing matters: the $99 sits on top of the plan, and the interaction meter has the same property as a per-call one. Compare the total against a standalone service before assuming the bundle is cheaper.

Specialty Answering Service and PATLive: live humans, pay as you go

These two publish the lowest human entries. Specialty Answering Service starts at $44 a month with no minutes included and $1.54 a minute after, rising through $159 for 100 minutes and $269 for 220, with a 14-day free trial and no setup fee. PATLive is $49 a month pay-as-you-go with $2.99 a minute, also on a 14-day trial.

The shape is honest and the arithmetic is easy: a three-minute call costs about $4.60 at SAS and about $9 at PATLive. For a business that takes a handful of calls a week and wants a US-based person on every one of them, that is a reasonable monthly total. For one that takes a hundred, it is not, and both vendors' higher bundles are built for exactly that reader.

Ruby and Abby Connect: when a person is the requirement

There are businesses where a human voice is not a preference but a condition of the sale: high-value professional services, anything where the first call is emotionally heavy, and firms whose entire brand is the warmth of the interaction. Ruby in particular has built a reputation on exactly that and it is not a reputation any AI vendor can claim.

Ruby publishes $250 a month for 50 receptionist minutes, $395 for 100, $720 for 200 and $1,725 for 500, plus chat bundles from $115. Abby Connect publishes $165 for 50 minutes, $329 for 100, $599 for 200 and $1,380 for 500, and now sells a human-plus-AI mix where you choose which calls get which. Abby is the cheaper of the two at every rung and pitches a small dedicated team rather than a pool; Ruby is the better-known name.

The trade-off is consistent across both. Per-minute billing, meaning a volatile month is an expensive month; a shared operator who does not know your prices or your diary unless you have briefed them; and, at these rates, a monthly total that is a part-time salary before the first overage minute.

Slang.ai: if you are a restaurant, start here

From $399 a month per location, built specifically for restaurants, with end-to-end integration into OpenTable, SevenRooms, Yelp and Fishbowl. Nothing else on this list has that depth in one vertical.

If your reservation platform is on that list and your problem is the phone at 7:40 on a Friday, the vertical integration is worth more than a lower headline price. If you run several small locations, the per-location meter is the thing to model carefully.

AnswerConnect, RingCentral, Nexa, AnswerForce: no published price

Four of the eleven publish nothing. AnswerConnect's "view pricing" page is a form asking for your name, email and phone, and its /pricing URL is a 404. RingCentral's AI Receptionist page says contact sales. Nexa's plans page and AnswerForce's site carry no figure at all.

That is not a reason to exclude them and it is not necessarily a bad sign; a large multi-location operation with a procurement process will get a quote that fits it. It is a reason to know, before the call, what the published market looks like, because the one thing a sales conversation cannot do is show you the price the last customer paid.

How to actually choose

Three questions, in order. First, how volatile is your call volume. If one week a year triples it, discount every per-call and per-minute meter. Second, do you need the phone to book, or is a message enough? If a message is enough, the traditional services are mature and cheap, and Rosie's $49 tier does exactly that. Third, is there a compliance requirement, because that eliminates most of this list including us.

Then test. Every vendor here with a price also has a trial: 7 days at Rosie and Dialzara, 14 at SAS and PATLive, 25 free calls at Smith.ai, a free tier at Vandial and Phonely. Ask each one something it should refuse and listen to how it refuses; that is the risk you are actually buying.
