On this page
Ask what AI customer support costs and you get two answers: a vendor's headline number, and a case study with a percentage in it. Neither tells you what will land on your card. This is the version with published prices and the arithmetic left visible.
What you are actually billed for
Almost every quote is a blend of five things. Compare vendors line by line, not on the headline.
| Line | Typical unit | What makes it move |
|---|---|---|
| Human seats | per agent, per month | how many people still answer chats |
| AI outcomes | per resolution or conversation | volume, and the vendor's definition of "resolved" |
| Model usage | per conversation, metered | how much of your content the assistant reads each time |
| Channels and add-ons | per channel or per feature | voice, WhatsApp, extra languages, analytics |
| Your time | one-off, then monthly | writing the content, the rules, the review habit |
The third line is the one people forget: an assistant that reads your whole site on every message costs more than one pointed at the right page, which is why a tidy llms.txt is a cost control and not only an SEO chore.
Published list prices, September 2026
These are the vendors' own numbers, taken from their public pricing pages. They are starting points, not what anyone actually pays after volume and negotiation.
- Intercom: Fin, its AI agent, is "from $0.99 per Fin outcome". Human seats are $29 (Essential), $85 (Advanced) and $132 (Expert) per seat/month billed annually. An outcome counts when the customer confirms resolution, does not ask again, or a workflow completes — including hand-offs.
- Tidio: a free plan with 50 billable conversations a month, Starter at $24.17/month, Growth from $49.17/month, and Plus from $300/month plus usage starting at 3,000 AI conversations. The AI agent alone starts at $32.50/month for 50 conversations.
- Zendesk: Suite Team at $55 and Suite Professional at $115 per agent/month paid yearly, with AI agents billed on "automated resolutions" — the requests resolved without escalating to a human.
Three vendors, three billing units: per outcome, per conversation, per automated resolution. That is the single most important thing on this page. A price you cannot convert into your own volume is not a price.
Work out your own number
No calculator can do this for you honestly, because only you know the shape of your volume. Fill this in from your own last twelve months.
Cost worksheet for [Business name]
Conversations per month: [ 400 ]
Share the assistant can fully handle: [ 60% ] -> AI units/month [ 240 ]
Vendor unit and price: [ per resolution ] at [ $0.99 ]
AI line = [ units x price ]
Human seats still needed: [ 1 ] at [ seat price /mo ]
Seat line = [ seats x price ]
Add-ons you will actually switch on: [ voice? ] [ WhatsApp? ] [ extra languages? ]
Setup time, first month: [ hours ] x [ your hourly cost ]
Compare against: what [ 240 ] conversations cost you in staff time today.Two sanity checks. If a vendor's "resolution" includes conversations where the assistant only handed off, your effective price per actually solved question is higher than the sticker. And if your volume is spiky — a seasonal shop, a campaign — per-unit pricing is your friend; if it is high and flat, seats usually win.
Ask your assistant to run the comparison
Ask your AI assistant:
I get about [N] customer conversations a month, mostly about [topics]. Here are two
vendor pricing pages: [url 1], [url 2]. For each, work out my monthly cost at 40%, 60%
and 80% of conversations handled by AI, state exactly what their billable unit is and
what it excludes, and list every line that is not in the headline price. Do not estimate
anything you cannot read from the page — mark it [CHECK] instead.Then read what it produced with a sceptical eye. Any figure that did not come off a pricing page is a guess, including one an assistant makes.
What we charge
Ours is deliberately simple to describe and impossible to shrink into a headline tier: pricing is per business and metered on conversations and model spend, with white-label and custom domains included and no per-seat tax on your colleagues. There is no public price card to quote here because the number depends on your volume, so the honest thing is to run yours and talk to us. The usage docs explain exactly what is metered.
The cheapest lever is not the vendor
Before comparing anyone, fix the content. Most "the AI could not answer" cases are "the answer was never written down" cases, and every extra escalation costs you a human minute at whatever a human minute costs. Write down prices, hours, policies and the ten questions you answer weekly — then build an assistant from your URL and watch which questions it fumbles. That list is your cheapest month of work, and it makes every vendor on your shortlist perform better.
The same content also decides how well the customer-support hand-off works, and whether an agent can go beyond answering to acting — WebMCP and page tools are what turn a resolved conversation into a booked appointment, which is the only ROI number that ever really mattered.
Questions
How much does AI customer support cost per month?
There is no honest single figure, because the bill is a mix of seats, resolved conversations and model usage. Published starting points range from about $25 a month for a small chat plan to per-outcome pricing from $0.99, before any human seats.
What is a "resolution" and why does it matter so much?
It is the billable unit most AI support vendors use, and every vendor defines it differently. One counts a resolution when the customer confirms or simply stops asking; another counts requests handled without escalation. Read that definition before you compare two prices.
Is per-resolution pricing cheaper than per-seat?
It depends entirely on your volume shape. Per-resolution rewards low, spiky volume and punishes high volume; per-seat does the opposite. Model both against your last twelve months of tickets before choosing.
What does it cost to run one myself with an API?
Less in licence fees and more in your time. You still pay model usage per conversation, and you take on the content work, the escalation rules, the monitoring and the maintenance that a hosted product includes.
What is the hidden cost nobody quotes?
Content. An assistant is only as good as what it can read, so most of the real first-month cost is somebody writing down prices, policies and hours properly — work that pays off regardless of which vendor you pick.
