How Much Does an AI Voice Agent Cost? 2026 List Prices vs Human Answering Services

How Much Does an AI Voice Agent Cost?

On the price lists we read on 11 October 2026, Retell AI lists $0.07 to $0.31 a minute and Bland AI lists $0.14 a minute, both pay as you go. A ready-made AI receptionist is sold by the month: Dialzara from $29, Goodcall from $79, My AI Front Desk $99. A custom-built agent has no list price. Each figure is the published price on that vendor's own pricing page.

The figures sit far apart because they are three different purchases. A platform sells minutes, and you or a developer build the agent on it. A receptionist product sells a finished agent on a monthly plan. A custom build is a project, made for your call types and your systems, and you own what is built. A human answering service is the fourth option, and two of them publish their prices as well.

AI Voice Agent Pricing on 11 October 2026: Ten Published Price Lists

We opened ten price lists from nine vendors on 11 October 2026 and copied the plan names, prices and limits as written. Each row links to the page it came from. All prices are in US dollars.

Each figure is the list price on the linked page, exactly as the vendor states it. Prices change, so open the link before you budget. A longer list of products, with what each one does, is in our guide to AI receptionist and voice agent products for small business.

What Each Price List Sells, and Which Buyer It Suits

A business that wants every call answered can buy one of four services. Each suits a different kind of call, and each tells you a different amount on its price list.

1. A Pay-As-You-Go Voice Agent Platform

Retell AI, Bland AI and Vapi sell the working parts of a voice agent and bill by the minute. Someone still has to design the conversation, connect the calendar or CRM and test it. That can be your own developer or a firm you hire. This route suits a business with technical help on hand, and one whose call volume swings through the year: Retell AI and Vapi state no minimums, and the Bland AI Start plan carries a $0 platform fee.

Read what the per-minute number covers. Every call uses four parts: a phone line, speech to text, a language model that decides what to say, and text to speech. Bland AI says its rate covers the language model, speech to text and text to speech, with telephony billed separately. Vapi says its $0.05 a minute is for the Vapi platform, with models passed through at cost. Retell AI publishes a range and a calculator that moves with the model, voice and telephony you pick. Two per-minute numbers compare only when they cover the same parts.

2. A Ready-Made AI Receptionist Product

Dialzara, Goodcall, My AI Front Desk and Smith.ai sell a finished agent you subscribe to. Depending on the plan, it answers, takes messages, books appointments and transfers calls. If your calls are reasonably standard and your scheduling software is mainstream, one of these products will be live faster and cheaper than anything custom, and for many businesses it is the right answer.

Check the unit before you compare two of them. Dialzara and My AI Front Desk include an allowance of minutes. Smith.ai counts calls. Goodcall counts unique customers and says it never meters minutes. At the enterprise end, Synthflow lists contracts from $30,000 a year.

3. A Human Answering Service

A person picks up. That counts most on the hard calls: a caller who is frustrated, a caller describing a serious injury, a caller asking for a specific specialist.

Human services price a minute or a call of a person. The Ruby plans page lists 50 receptionist minutes at $250 a month, 100 at $395, 200 at $720 and 500 at $1,725. The Smith.ai receptionist pricing page lists 30 calls at $300 a month, 90 at $810 and 300 at $2,100, answered by its own staff. We read both lists at those links on 11 October 2026.

One list sells minutes and the other sells calls, so you need your own average call length before you can set them side by side. Both step up with volume, so check which tier your busiest month would land in.

A shared service answers for many unrelated businesses, so the same operator may take a dental clinic call straight after a roofing inquiry. Before you sign, ask what its operators can do beyond taking a message, such as following your scheduling rules, checking live inventory or triaging a technical problem.

4. A Custom-Built Voice Agent

A custom build earns its cost when you hit a wall those products cannot pass: an intake process that does not fit their logic flows, a system they will not integrate with, a legal or industry requirement they cover only on a plan priced beyond your budget, or a workflow spanning several tools. On a custom build you own the repository, the telephony backend and the prompt state machines outright, with no per-seat licensing. The agent writes confirmed appointments and parsed intake straight into your practice management system, DMS or CRM.

A custom build has no price list to read, because the price depends on what is built. FactoryJet quotes the build and the ongoing support as fixed prices in writing after a short scoping call. We keep managing the servers, the AI, the APIs and the maintenance, so your team does not have to.

FactoryJet builds AI voice agents for call centers as well as small offices. The scope for a small office is on our AI receptionist service page, and the scope for a larger team is on our AI call center agents page. If you run a medical or dental practice, the rules on patient data change the choice enough to need a separate guide: what an AI medical receptionist costs.

How Much Does an AI Voice Agent Cost Per Month?

On a ready-made product, the month is the plan price. The entry plans on 11 October 2026 were Dialzara at $29 a month for up to 60 minutes, Goodcall at $79 a month for 100 unique customers, My AI Front Desk at $99 a month with 200 voice minutes, and Smith.ai AI Receptionist at $150 a month for 75 calls. Smith.ai also lists a Free plan at $0 a month for 25 calls.

Higher up the same lists, Dialzara reads $349 a month for up to 1,000 minutes, Goodcall $299 a month for 2,000 unique customers, and Smith.ai AI Receptionist $800 a month for 500 calls.

A pay-as-you-go platform has no plan price to quote. The month is the minutes your callers use at the listed rate, plus anything the list prices beside it, such as phone numbers or extra concurrent lines. Two of the three add a fixed part on higher plans. Bland AI lists a $299 a month platform fee on Build, and Vapi lists its Core success package at $29 a month.

Human answering services publish monthly plans as well. Ruby starts at $250 a month for 50 receptionist minutes and Smith.ai at $300 a month for 30 calls.

Which Vendors Offer Pay-As-You-Go Pricing for AI Voice Agents?

Three of the lists we read have a plan that bills only for use. That suits a business whose calls rise and fall with the season, such as a construction or roofing contractor.

• Retell AI: $0.07 to $0.31 a minute. It starts at $0, with no minimums or contracts, and includes 20 concurrent calls.
• Bland AI, Start plan: $0.14 a minute with a $0 platform fee. It includes 10 concurrent calls and up to 100 calls a day.
• Vapi, usage only: $0.05 a minute for the Vapi platform, with models passed through at cost. It starts at $0 with no minimum minutes and 4 concurrent calls, and lists extra lines at $10 a line a month.

In a spike, the number that decides who gets an answer is concurrent calls: how many callers the plan can talk to at the same moment. Goodcall handles peaks a different way. It lists no per-minute charge and bills by unique customer, so a long booking call counts the same as a short one.

AI Voice Agent or Human Answering Service: Which Calls Suit Which

Most businesses get more than one kind of call, so the answer is often two services working together.

• Routine bookings and standard questions: an off-the-shelf AI receptionist, when your scheduling software is mainstream.
• Calls that arrive all at once: an AI agent, bought or built, up to the concurrent call limit on your plan. On a product, check that limit on the plan you are buying.
• Calls where judgement counts: a person. When a caller is frustrated, describes a serious injury or asks for a specific specialist, the call should go to a human answering service or to your own on-call staff. A well-built agent transfers it with a summary of the conversation already captured.
• Calls that depend on your own systems: a custom-built voice agent, when your intake does not fit the logic flows of a product, the product will not integrate with a system you use, or one workflow spans several tools.
• After-hours calls: the place to start with any AI agent. Begin with after-hours only, listen to real recordings every week, and expand once you trust it.

How to Compare Two Price Lists in Five Steps

1. Count your calls and your average call length for your busiest month. You need both numbers, because some lists sell minutes and others sell calls.
2. Write down the unit each list sells. Ruby, Dialzara, Retell AI, Bland AI and Vapi sell minutes. Smith.ai sells calls. Goodcall sells unique customers.
3. Read what the price covers. On a per-minute platform, check whether the language model, the voice and the phone line are inside the number or listed beside it.
4. Check the limits and the price of going over. Look for concurrent calls, calls per day and the price of an extra minute or call. Dialzara lists $0.35 to $0.48 for an extra minute, and Smith.ai lists $8.50 to $11.50 for an extra call on its human plans.
5. Listen to a real call before you pay. Ask to hear the agent say it does not know and pass the caller to a person. Listen for the pause before each reply and for what happens when you interrupt.

What a Missed Call Is Worth to You

Whichever service answers, the value sits in the calls that would otherwise be missed. Count the calls that went unanswered last month, the share of answered calls that turn into a booking, and what an average booking is worth. Those are your own numbers, and they tell you which of these price lists is worth paying.
