What an AI Receptionist Actually Costs in 2026

Across 18 vendors checked on July 20, 2026, published entry prices for AI phone answering split into two shapes. Flat monthly plans ran from $49 to $449 per month, with a median advertised entry of $98. Usage-priced platforms ran from $0.05 to $0.31 per minute. Six of the 18 published no price at all and route you to a demo instead. For a small service business handling a few hundred inbound calls a month, the self-serve tier of this market lands in the $50 to $400 per month band before any integration work. The spread is real, and the rest of this post explains what moves you inside it.

How was this pricing audit done?

On July 20, 2026, we opened the public pricing page of every AI receptionist, AI phone agent, and answering service vendor we could reach, and recorded four things: whether a price appears at all, the pricing model, the advertised entry price, and whether a demo is required to learn any number. We reached 18 of 19 attempted. Dialpad blocked automated access with an HTTP 403, so we did not verify its numbers firsthand and excluded it from the counts.

One limitation matters more than the rest: an advertised entry price is a shelf price, not a bill. Most entry tiers cap minutes, calls, or unique callers, and the overage rate is where the real cost lives. Treat the table below as a map of what vendors are willing to say in public, not a forecast of your invoice.

What does each vendor publish?

Twelve of 18 published a price. Six published none. The AI-native products cluster far below the human answering services, and the two platform vendors aimed at developers price by the minute rather than by the plan.

How many vendors make you talk to sales?

Six of 18 published nothing, and a seventh published only a floor. Smith.ai, Numa, Nexa, AnswerConnect, PolyAI, and Podium all replace a price with a form. Synthflow states only that "Enterprise contracts start at $30,000 annually." That is a third of the market where you cannot compare anything without booking a call.

Sales-gating is not automatically a red flag, but it does tell you something about the buyer the vendor built for. Every vendor priced under $100 per month publishes that price openly. If a vendor will not name a number for a ten-line business, you are not the customer the pricing was designed around.

Which pricing model fits a small service business?

Three models dominate. Flat monthly with a minute or call cap is the most common and the easiest to budget. Per-minute usage pricing, used by Vapi, Retell AI, and Bland AI, is cheapest at low volume and scales linearly with talk time. Per-location or per-seat pricing, like Slang.ai at $399 per location, punishes multi-site operators and rewards single shops.

A fourth variant is worth naming because it changes the math entirely. Goodcall bills on unique customers served rather than minutes, stating it does not charge "for number of calls call minutes, or tokens consumed," with overage at $0.50 per customer past the tier limit. If your callers repeat often, that model is cheap. If every call is a new caller, it is not.

What actually drives the monthly bill?

Four things: how many inbound calls you get, how long the average call runs, how many add-ons you switch on, and how the vendor rounds. Minute rounding is the quiet one. PATLive charges $2.60 per minute on its $75 base plan, so a shop with lots of short calls pays for a lot of partial minutes.

Add-ons stack fast and are usually priced separately from the plan. Slang.ai charges $99 per month for bilingual support and $199 per month for its Tripleseat events integration. PATLive charges $20 per month each for bilingual answering and extra scripts. Vapi charges $2,000 per month for HIPAA and $1,000 per month for zero data retention, which is the single largest line item in this entire audit for a regulated business. Rosie adds website texting at $50 per month plus $1 per conversation past 25.

After-hours share is the multiplier most owners underestimate. If a third of your call volume arrives when nobody is at the desk, that third is what the agent handles, and it is also the volume that decides whether the spend pays for itself. Our missed call statistics page covers the volume side of that question.

How do you estimate your own cost?

Pull real numbers rather than trusting a vendor calculator. The whole estimate takes about an hour if your phone system exports call logs, and it produces a figure you can hold a salesperson to.

1. Export 90 days of call detail records from your carrier or phone system. Count inbound calls only, and drop internal transfers.
2. Split those calls by hour. Mark everything outside staffed hours as after-hours volume, and mark daytime calls that went unanswered separately.
3. Sum the two marked buckets. That is your candidate volume, the calls an AI agent would actually take. It is almost never your total call count.
4. Multiply candidate volume by your average handle time from the same export. If your system does not report handle time, measure 20 calls by hand rather than guessing.
5. Price that minute figure against one flat plan and one per-minute platform from the table above. Include the overage rate, not just the tier price.
6. Add every add-on you actually need: bilingual, calendar booking, CRM write-back, compliance, extra locations. Price them line by line.
7. Add the build. Scoping, prompt writing, integration testing, and the first two weeks of correction are real hours whether you or a vendor do them.
8. Recheck against your first real invoice after 60 days. Adjust the plan tier then, not before.

What is a realistic monthly range for a small business?

For a single-location service business on a self-serve product, the published market puts you between roughly $50 and $400 per month. Rosie at $49 for 250 minutes anchors the low end, Abby Connect at $99 for 100 minutes and Simple Phones at $97 for 100 calls sit at the median, and Sameday AI at $449 for 500 minutes marks the top of the self-serve band.

Human answering services sit above that for equivalent coverage. Ruby charges $250 per month for 50 minutes and $720 for 200, and Abby Connect charges $329 per month for 100 human-answered minutes against $165 for the same AI tier. The AI discount at matched volume is roughly half, which is the clearest single finding in this data.

When does the advertised price stop being the real price?

The moment your volume crosses the tier cap, or the moment a required capability lives in an add-on. A $99 plan with 50 included minutes and a $2 overage becomes a $300 plan at 150 minutes. That is not a bait and switch, it is just how minute tiers work, and it is why step 5 above says to price the overage rate.

Integration is the second gap. Vendors that gate pricing tend to gate it because the deployment is scoped work. Synthflow says its final pricing is scoped around "call volume, concurrency, telephony setup, integrations, security needs, and launch support." Those five variables exist for every vendor. The cheap ones simply make you absorb them yourself.

What should you ask before you sign?

Ask five questions and write down the answers. What is the overage rate per minute or per call. What is the minimum contract term. What is the setup or onboarding fee, since Nexa discloses that a setup fee exists without publishing the amount. Which integrations are included versus billed. And what happens to your call recordings and transcripts.

If you want the calls that agent answers to turn into booked work rather than logged messages, the routing and follow-up matter as much as the answering. That is the difference between missed call recovery and a voicemail box with better manners, and it is why appointment scheduling is usually the feature that decides whether the spend returns anything.
