How Much Does an AI Chatbot Cost? (2026 Pricing)

An AI chatbot for a growing business costs anywhere from $0 to about $150 a month on a do-it-yourself builder, roughly $1 to $2 per resolved conversation on a help desk platform's built-in AI, and $5,000 to $25,000 to build as a custom chatbot, plus $100 to $800 a month to run. A chatbot that does more than answer questions, one that checks orders, books appointments or issues refunds inside your systems, is really an AI agent and typically costs $15,000 to $45,000 to build. The right number for you depends less on the AI model and more on three things: how many conversations you handle each month, how many of your systems the chatbot has to touch, and what a wrong answer would cost you. This guide breaks down each pricing model so you can compare a quote, a subscription and a per-resolution bill on the same basis.

This post is part of our series on AI agent costs and ROI. For the full picture of what custom agents cost to build and run, see the main guide at wizeb.com/blog/ai-agent-cost-guide.

Why AI Chatbot Prices Are So Hard to Compare

The word "chatbot" covers three very different products, and vendors price each one differently.

• A scripted bot follows buttons and decision trees. It is cheap, predictable and frustrating the moment a customer phrases something in a way you did not plan for.
• An AI answer bot uses a language model to reply in natural language from your help articles, policies and product pages. It understands how people really ask questions, but it can only tell customers things. It cannot change anything.
• An AI agent reads and writes to your systems. It can look up an order in Shopify, change a booking, start a return or update your CRM, within limits you set.

A $49-a-month tool and a $30,000 build are not two prices for the same thing. Before you compare costs, decide which of the three you need. If you are unsure where the line sits, our explainer at wizeb.com/blog/ai-agent-vs-chatbot-vs-automation walks through the difference with examples.

The Four Ways to Pay for an AI Chatbot

1. DIY chatbot builders: $0 to $150 a month

Website chat tools with an AI option let you upload your FAQ and help pages and switch on an answer bot in an afternoon. Plans usually charge by the number of conversations or AI replies per month, with a free tier for low volume. This is the right choice for a small business that mostly gets the same ten questions and has nobody to maintain anything more complex. The limits show up quickly: answers are only as good as the pages you upload, and the bot cannot see order status, account details or availability.

2. Help desk AI billed per resolution: about $1 to $2 per conversation

The big help desk platforms now sell AI that answers inside the help desk you already use, and they bill per conversation the AI resolves rather than per seat. Intercom charges $0.99 per resolution for its Fin AI agent (intercom.com/pricing). Third-party breakdowns of Zendesk's plan table put its automated resolutions at about $1.50 each on a committed volume and $2.00 pay-as-you-go, after a small allowance included with each plan (eesel.ai/blog/zendesk-ai-pricing). Seats for your human team are billed on top.

Per-resolution pricing is easy to start and easy to justify, because you only pay when the AI does the work. The catch is that the bill grows in step with your success. A bot that resolves 3,000 conversations a month at $0.99 costs about $35,600 a year; at $2.00 it costs $72,000. That is fine when volume is modest. At high volume it is often more than a custom build would cost over two years.

3. Custom AI chatbot: $5,000 to $25,000 to build

A custom chatbot is built for your content, your tone and your channels (website, WhatsApp, SMS, Slack or your app), on a model you choose. You pay once for the build and then a running cost for model usage and hosting, which for most small and mid-sized businesses is $100 to $800 a month. The low end is an answer bot over a well-organised knowledge base on one channel. The high end adds several channels, multiple languages, hand-off to a live agent with the full conversation attached, and a proper testing set so you know how accurate it is before customers see it.

4. A chatbot that takes action (an AI agent): $15,000 to $45,000

Most of the value in customer conversations is not in answering "what is your returns policy". It is in "where is my order", "can I move my booking to Thursday" and "I was charged twice". Answering those means connecting to your order system, calendar, payment provider or CRM with the right permissions, and testing what happens when something goes wrong. Each system adds build time, which is why the jump in price from an answer bot to an agent is mostly integration and testing, not AI. Our guide at wizeb.com/blog/ai-customer-service-agent covers what a support agent of this kind handles and how to set it up.

What a Custom Chatbot Costs to Run Each Month

Build cost is paid once. Running cost is paid every month, and it is the part most quotes leave vague. For a custom chatbot it has four parts.

• Model usage. Every conversation uses tokens, billed by the model provider per million. For a few thousand conversations a month this is often $30 to $300, depending on the model and how much of your knowledge base the bot reads per question. Routing simple questions to a smaller model and caching repeated context can cut this by half or more.
• Hosting and search. Servers or serverless functions, a database and a search index over your content: usually $20 to $150 a month.
• Channel fees. WhatsApp Business and SMS charge per message or conversation; website chat is free. Voice is a different budget entirely, because telephony and speech minutes cost more than the language model.
• Maintenance. Your products, prices and policies change, and the bot has to keep up. Budget 15 to 25 percent of the build cost a year, often as a small monthly retainer, plus a couple of hours a week from the person who owns customer service to review flagged conversations.

The Hidden Costs of a Cheap Chatbot

The cheapest chatbot is not always the cheapest outcome. These are the costs that rarely appear on a pricing page:

• Wrong answers. A bot that confidently quotes last year's prices or an old refund policy creates complaints, refunds and in some cases legal exposure. Keeping its knowledge current is a running job, not a one-off upload.
• Deflection that is not resolution. A bot that sends customers to a help article and closes the chat can report a high "resolution rate" while your email queue fills up with the same people asking again.
• Dead ends. Without a clean hand-off to a person, with the conversation history attached, frustrated customers start over on the phone. That costs more than the conversation the bot saved.
• Usage you cannot see. Per-resolution and per-conversation pricing is hard to forecast in a busy month. Set a budget and an alert from day one; our guide at wizeb.com/blog/ai-agent-cost-budgeting-pay-as-you-go-2026 covers how.

Per Resolution vs Custom Build: Where the Lines Cross

The useful comparison is total cost per resolved conversation over two years, not the monthly sticker price. A rough way to find your break-even point:

1. 1Count the conversations you expect the AI to fully resolve each month. Be honest: 40 to 60 percent of all chats is a realistic target in the first year for most businesses.
2. 2Multiply by the per-resolution price and by 24 for the two-year platform cost.
3. 3Add the custom build price to 24 months of its running cost.
4. 4Compare the two, then weigh what the numbers leave out: what each option can connect to, who owns the logic and data, and how easily you can switch later.

As a rule of thumb, under about 500 resolutions a month a platform's built-in AI is usually cheaper and faster. Above about 1,500 a month, or when the bot has to act in systems the platform cannot reach, a custom build usually wins. In between, the deciding factor is rarely price; it is fit. Measure the result per resolved conversation, not per message or per token, as wizeb.com/blog/ai-agent-cost-per-outcome-2026 explains.

Example: Pricing a Chatbot for a UK Online Retailer

This is an illustrative example, but the numbers are typical. A 30-person UK homeware brand selling on Shopify gets about 4,000 customer chats and emails a month. Around 60 percent are order status, delivery dates and returns; the rest are product questions and complaints.

• Help desk AI per resolution: if the AI resolves 2,000 conversations a month at $0.99, that is about $1,980 a month, or roughly £1,550, before seats. Two-year cost: about $47,500. It can answer product and policy questions well, but order status and returns need extra integration work the brand would have to pay for anyway.
• Custom chatbot with Shopify and returns integration: about $22,000 to build over seven weeks, covering the order lookup, returns flow, live-agent hand-off and testing on six months of past chats. Running cost about $450 a month, of which $180 is model usage. Two-year cost: about $32,800.
• Result: at this volume the custom build costs about $15,000 less over two years and handles the order and returns questions that make up most of the queue. At a quarter of the volume, the per-resolution option would have been the better deal.

The point is not the exact figures. It is that the right choice falls out of your volume and the systems the bot has to reach, and you can work it out before you sign anything.

Five Questions to Price Your Chatbot Before You Call a Vendor

1. 1How many conversations a month, across which channels?
2. 2What share are answered from information alone, and what share need the bot to look something up or change something?
3. 3Which systems would it need to read from or write to, and do they have APIs?
4. 4What happens if it gets an answer wrong, and who reviews its mistakes?
5. 5Do you handle data covered by GDPR, HIPAA or payment card rules?

Information-only questions on one channel point to a DIY tool or help desk AI. Look-ups and actions across two or more systems point to a custom build. Once you have a number, the guide at wizeb.com/blog/how-to-measure-ai-agent-roi shows how to check that it pays back.
