AI Chatbot Pricing in 2026: What You Will Actually Pay (After 126 Builds)

Most small businesses pay $19 to $400 a month for an AI chatbot in 2026, mid market teams pay $500 to $3,000, and enterprises on per resolution pricing pay $5,000 to $15,000. The cheapest AI chatbot I have quoted a client was $19 a month and the most expensive one I run costs $11,400, and they are the same category of product. What separates them is volume and pricing model, not features. There are four models in this market: per resolution, per seat, per message credit, and flat tier, and each of them wins at a different volume, which is why comparing sticker prices across vendors tells you almost nothing.

Concretely: Intercom Fin charges $0.99 per resolution on top of $19 to $139 per seat depending on plan and billing, which gets expensive quickly above 5,000 resolutions a month. Chatbase, Botpress, and Tidio own the small business band at $24 to $400 a month with predictable caps. A custom RAG chatbot on Bedrock or OpenAI starts near $300 a month in infrastructure before build cost. Then add 20% to 40% for the things nobody quotes: overage fees, integration time, and keeping the knowledge base current.

The cheapest AI chatbot pricing I have ever quoted a client was $19 a month. The most expensive one I have shipped runs $11,400 a month. Same category of product. Different volume, different vendor, different math. If you are searching for clear numbers before you sign anything, you are in the right place.

I have built 126 production AI systems across law firms, contractors, ecommerce stores, and SaaS companies. I have seen every pricing model in the wild, and I have watched several of them quietly bankrupt support budgets that looked fine on paper. This is the post I wish my clients had read before they signed up.

What does an AI chatbot actually cost in 2026?

An AI chatbot in 2026 costs between $19 and $400 a month for most small businesses, $500 to $3,000 a month for mid market companies with moderate ticket volume, and $5,000 to $15,000 a month for enterprises running per resolution pricing at scale. Custom built chatbots add a one time build cost of $5,000 to $50,000 plus ongoing infrastructure of $300 to $2,000 a month.

If you only read one section of this post, read this table. It is the pricing reality across the platforms I deploy and audit most often, with list prices rechecked on October 14, 2026. Where a vendor charges less for annual billing I show the annual price and put the monthly price in brackets.

The four AI chatbot pricing models you will see

Almost every quote you receive in 2026 will use one of four pricing models. Knowing which one a vendor uses tells you instantly whether their math will work at your volume.

1. Per resolution pricing

You pay each time the chatbot successfully closes a customer issue without human handoff. Intercom Fin charges $0.99 per resolution (Intercom's own word for it is an outcome). Zendesk's autonomous AI agents charge $1.50 per automated resolution on committed volume or $2.00 pay as you go once you pass a small included allowance, and several other enterprise vendors use the same model. The pitch is that you only pay for value delivered. The reality is that successful resolutions scale linearly with traffic, and at 10,000 resolutions a month you are looking at $9,900 in resolution fees alone, on top of seat costs.

I deployed Fin for a B2B SaaS client last year. Their previous bill was $1,200 a month on Intercom seats. Three months after Fin went live and their support volume grew, the combined bill hit $7,800. The product worked. The pricing did not.

2. Per seat or per agent pricing

Flat fee for each human agent in the system, regardless of how many tickets they handle. Zendesk Suite Professional runs $115 per agent per month billed annually ($149 monthly), and Copilot adds $50 per agent on top, which is $165 together. Intercom's Advanced plan is $85 per seat billed annually ($99 monthly). This model is predictable, but it punishes teams that hire more agents and rewards companies that lean harder on automation. Zendesk's pricing page shows how the add ons stack: Copilot ($50) and the Workforce Engagement Bundle ($50, a quality and agent performance add on; Quality Assurance and Workforce Management were listed at $35 and $25 separately in April 2026) are separate line items, and AI agents add per resolution charges once you pass the included allowance.

3. Per message credit pricing

You buy a pool of message credits each month. Chatbase Standard gives you 4,000 credits for $120 a month billed annually ($150 monthly). When you exceed the cap, you either upgrade or pay overage at $40 per 1,000 credits. This model is friendly to small businesses with predictable volume and brutal to anyone who hits a viral moment. I have seen one client blow through 18,000 credits in a single weekend after a Reddit post.

4. Flat tier or per contact pricing

You pay a tier price based on how many active users (or contacts, or workspaces) you have. ManyChat charges $14 a month for 250 active contacts and jumps to $139 a month for 25,000 (annual billing, or $17 and $199 monthly). Crisp charges per workspace. Botpress's Plus plan was $79 a month flat plus your raw AI spend on whichever LLM you point it at, and since May 14, 2026 new workspaces pay $150 a month billed annually for 250 conversations with AI usage included. This is the most predictable model and the easiest to budget against.

Real AI chatbot pricing breakdown by platform

Here is the actual current pricing for the platforms I deploy and audit most often, captured directly from each vendor's pricing page in April 2026 and rechecked against the same pages on October 14, 2026. Where the two readings differ I show the October one. Annual billing prices come first and monthly billing prices follow in brackets.

Intercom + Fin AI Agent

Intercom's Essential plan is $19 per seat per month billed annually ($29 monthly), Advanced is $85 per seat per month ($99 monthly), and Expert is $132 per seat per month ($139 monthly). Intercom appears to be testing its prices: on October 14, 2026 the same pricing page showed Essential at $19 per seat per month billed annually ($29 monthly) on one load and $29 ($39 monthly) on another, with Advanced and Expert unchanged, so check the price you are shown when you buy. Every plan includes Fin, billed at $0.99 per resolution (Intercom now calls it an outcome). Fin works on top of Intercom or as a standalone agent on Salesforce, Zendesk, and other helpdesks (also $0.99 per resolution, no seats required, with a $49 a month minimum that includes 50 outcomes). The Pro add on for AI insights is $100 a month, and Copilot is $29 per agent per month billed annually ($35 monthly) for unlimited usage. Fin Voice, for phone support, is sold through Intercom sales at $1.99 per voice outcome. Startups with under $10M raised and 15 or fewer employees can apply for Intercom's Early Stage program, which Intercom advertises at up to 93 percent off.

Verdict: Intercom is the right call if you already live in Intercom. If you are starting fresh and your ticket volume is high, the per resolution math will outpace cheaper alternatives by month four. Source: Intercom pricing and Fin pricing. If you are weighing Intercom against other helpdesks, I compare them in best AI chatbot customer service software.

Zendesk Suite + Copilot

Zendesk Suite Professional is $115 per agent per month billed annually ($149 monthly), so Suite Professional with Copilot is $165 per agent per month. The standalone plans (without Copilot) start at $19 per agent per month for Support Team and $55 for Suite Team, billed annually ($25 and $69 monthly), and Suite Enterprise is quoted by sales. Copilot as an add on is $50 per agent per month billed annually. AI agents are now included in every plan with 5 automated resolutions per agent per month (10 on Suite Professional, up to 10,000 a year), then $1.50 per resolution on committed volume or $2.00 pay as you go. The Workforce Engagement Bundle, Zendesk's quality and agent performance add on, is $50 per agent per month, and the comparison table still says AI agents for email require the QA add on.

Verdict: Zendesk is the default if you have 25+ agents and need full helpdesk infrastructure. The total cost per agent often lands at $200 to $300 once add ons stack: Suite Professional plus Copilot plus the Workforce Engagement Bundle is $215 per agent per month on annual list prices, before any resolution charges. Source: Zendesk pricing.

Tidio + Lyro AI Agent

Tidio's Starter plan is $24.17 a month billed annually, or $29 monthly (100 billable conversations a month and 50 Lyro AI conversations as a one off). Growth is $49.17 a month annual ($59 monthly) with 250 conversations. Plus now starts at $300 a month plus monthly usage, down from the $749 a month I recorded in April 2026. The Lyro AI Agent itself can also be added to Zendesk, Salesforce, or any other helpdesk as a standalone product, from $32.50 a month billed annually ($39 monthly) for 50 Lyro conversations.

Verdict: Tidio is the most price friendly option for ecommerce shops doing under 500 monthly conversations. The Lyro 50 conversation cap on the cheapest plan is the gotcha to watch. Source: Tidio pricing.

Chatbase

Chatbase's pricing page lists a 7 day trial on each paid plan and no Free plan when I checked on October 14, 2026, although Chatbase's own blog still says a free plan exists (it gave 50 message credits a month when I first recorded it in April 2026). Hobby is $32 a month billed annually ($40 monthly) with 700 credits, up from 500 in April 2026. Standard is $120 a month annual ($150 monthly) with 4,000 credits. Pro is $400 a month annual ($500 monthly) with 15,000 credits. Auto recharge is $40 per 1,000 additional credits. Voice and telephony unlock at the Standard tier. SSO is Enterprise only, and white labeling is Enterprise or a $99 a month add on that removes the Powered by Chatbase badge.

Verdict: Chatbase is my default recommendation for businesses that want a RAG chatbot trained on their own docs without a custom build. Standard tier covers 95 percent of small business needs. Source: Chatbase pricing. If you are choosing a builder rather than a helpdesk, best AI chatbot builder compares Chatbase with Botpress, Tidio, and Voiceflow.

Botpress

Botpress Pay as you go was $0 a month plus your AI spend (charged at provider rates). The Plus plan was $79 a month plus AI spend. Team was $445 a month plus AI spend. The fully managed plan was $1,245 a month for done for you bot building and ongoing maintenance. Every paid plan included a $5 monthly AI credit. That is what I recorded in April 2026, and on those legacy plans AI token usage is billed separately on top of your subscription. Botpress no longer lists those prices after it changed its plans on May 14, 2026, so I cannot verify them today.

The current plans apply to workspaces created after May 14, 2026, and Botpress said at launch that legacy workspaces keep their current pricing for now. I could not confirm whether that still holds in October. As of October 14, 2026 the page shows Free at $0 for 100 conversations, Plus at $150 a month billed annually ($189 monthly) for 250 conversations with extra packs of 100 for $65, and Team at $750 a month billed annually ($939 monthly) for 1,500 conversations with packs of 100 for $50. Botpress now charges per conversation, not per message, and bundles AI usage: every conversation includes $0.10 of AI usage, which is the $25 included on Plus and the $150 included on Team. Past that allowance Botpress buys a $10 credit grant of AI spend at cost when you reach 95 percent of your limit. Conversation packs work the same way: at 95 percent of your quota a pack of 100 is added automatically, and you cannot turn that off. A conversation counts once the visitor has sent at least two messages, and a voice call counts as one conversation per 3 minutes. The managed plan, now called Built For You, started at $1,650 a month in Botpress's May announcement and the pricing page now sends you to Botpress's sales form.

Verdict: Botpress is the right choice if you want maximum control over which LLM you use and you are willing to monitor usage yourself. On a legacy workspace the "+ AI Spend" addition is the variable that catches teams off guard, because AI token usage is billed separately on top of your subscription. For a typical SME chatbot running on Claude Haiku or Gemini Flash, budget $50 to $300 a month on a legacy Plus plan. That range is an estimate at Haiku 4.5 prices, not a Botpress figure: at six model calls per conversation, 8,000 input tokens and 300 output tokens per call, Claude Haiku 4.5 at $1 per million input tokens and $5 per million output tokens costs about $0.06 per conversation, which is $57 at 1,000 conversations a month and $285 at 5,000. Anthropic's newer Haiku 5.5 is listed at $0.10 and $0.50 per million tokens, a tenfold cut to $5.70 and $28.50 on the same assumptions, so a legacy workspace on that model would spend far less than the range above. On the new plans the $0.10 per conversation allowance covers that modelled usage, so the ceiling moves to conversation packs: a 1,000 conversation month on Plus is the 250 included plus 8 packs of 100 at $65, or $670 in total.

ManyChat

ManyChat Free gives you 25 active contacts. Essential is $14 a month billed annually ($17 monthly) with 250 active contacts. Pro is $29 a month ($39 monthly) with 2,500 active contacts. Business is $69 a month ($99 monthly) with 7,500 active contacts. Advanced is $139 a month ($199 monthly) with 25,000 active contacts. ManyChat AI is bundled into the Pro tier and above. ManyChat introduced this five tier model on March 2, 2026, and accounts created before that date are moving to it country by country. Past the cap you pay per extra contact: $0.10 on Essential, $0.05 on Pro, $0.025 on Business, and $0.004 on Advanced on monthly billing, a little less on annual (Essential is $0.08). At 1,000 active contacts, Essential on annual billing works out to $14 plus 750 extra contacts at $0.08, or $74, against $29 for Pro.

Verdict: ManyChat dominates Instagram, WhatsApp, and Messenger automation. It is not built for general customer support. If your funnel runs through Meta channels, this is your platform. ManyChat's own pricing page sat behind a bot challenge when I checked on October 14, 2026, so these figures come from its help center. Source: ManyChat help center, plans and pricing.

Voiceflow

Voiceflow moved to a custom usage based pricing model in 2026 and removed public price tiers from its site. As of October 14, 2026 its pricing page shows no prices on either track: agencies and partners start with a free trial and usage based billing, and businesses book a demo or request pricing. From client quotes I have seen this year, expect to pay between $200 and $2,500 a month depending on conversation volume and channels (voice agents cost more than chat). That range comes from those quotes, not from a published price. The platform is excellent for agencies managing multiple client deployments.

Verdict: If you need voice and chat agents under one roof and your team or agency builds for clients, Voiceflow is worth a sales call. Otherwise it is overkill.

Crisp

Crisp Free gives you a website chat widget for two seats and no AI credits. Mini is $45 per workspace per month with four seats and $5 of included AI credits (about 90 automated conversations). Essentials is $95 per workspace per month with ten seats, $25 of AI credits (about 450 automated conversations) and the omnichannel AI chatbot builder. Plus (the AI first support suite) is $295 per workspace per month with 20 or more seats and $75 of AI credits (about 1,350 automated conversations).

Verdict: Crisp's per workspace pricing keeps billing simple if you have a small team. Every paid tier now carries some AI credits, but the volume that justifies the comparison sits on Essentials and Plus, and Plus puts it in the same price range as Chatbase Pro. Source: Crisp pricing.

Custom built AI chatbot (the option no platform sells you)

If you want a chatbot that lives entirely in your stack, knows your specific data, and has no per resolution fees, you build it. The infrastructure cost on AWS Bedrock with Claude Haiku 4.5 plus a managed knowledge base runs $200 to $800 a month for typical small business volume. On OpenAI it lands at $150 to $600 a month. For the model line inside those figures, Anthropic lists Claude Haiku 4.5 at $1 per million input tokens and $5 per million output tokens, and the newer Claude Haiku 5.5 at $0.10 and $0.50 (checked October 14, 2026). The build cost ranges from $5,000 for a focused single use case to $50,000 for a multi channel agent with CRM integration and analytics.

I cover the build vs buy math in detail in Custom AI Chatbot vs Off the Shelf. The short version: you build when your data is sensitive, your workflows are specific, or your volume makes per resolution math impossible. You buy when you want to be live in two weeks for $200 a month. If you would rather have the custom route built for you, that is the work on my AI agent development page, and the build vs buy calculator and the AI agent cost calculator run the comparison on your own volumes.

Hidden costs no one mentions on the pricing page

Sticker prices are honest about themselves and dishonest about everything else. These are the line items that quietly add 20 to 40 percent on top of the published number, every single time.

Overage fees

Per message credit and per resolution platforms charge punishing overage rates. Chatbase overage is $40 per 1,000 credits. Intercom Fin keeps charging $0.99 per resolution forever. If you have any seasonality (holiday traffic, product launches, viral moments), build the overage into your annual budget or you will get surprised.

Setup and onboarding

Most vendors offer "free setup" but mean it loosely. Real onboarding for a production chatbot takes 20 to 80 hours of internal time across writing the knowledge base, configuring intents, building escalation flows, and testing edge cases. At a $75 per hour internal cost that is $1,500 to $6,000 in labor before the bot is useful.

Integration costs

Out of the box integrations are usually free. Custom integrations (your specific CRM, your specific shipping system, your specific calendar) are not. Plan for $1,500 to $8,000 in setup time depending on whether the integration uses native connectors, Zapier, n8n, or custom code. I write more about workflow plumbing in my n8n AI agent guide.

Knowledge base maintenance

The chatbot is only as good as what it knows. Maintaining a current knowledge base costs roughly 4 to 12 hours of internal time per month for a small business. Most teams underestimate this and watch quality degrade quietly over the first six months.

Annual lock in penalties

Annual billing usually saves 17 to 30 percent. On the list prices I rechecked in October 2026 the full spread runs from 5 percent (Intercom Expert) to 34.5 percent (Intercom Essential at $19 against $29 monthly). It also locks you in. If you cancel after three months, you do not get a refund on the remaining nine. I have seen clients overcommit to annual on a platform that turned out to be wrong for them. Try monthly first for at least 60 days before signing annual.

Three real client scenarios with monthly bills

Pricing pages give you ranges. These are the actual monthly numbers from three deployments I shipped in the last 12 months, with client names removed.

Scenario 1: Solo law firm, 80 conversations a month

The client wanted a website chatbot to qualify leads after hours and book consultations. Volume was low and predictable. We deployed Chatbase Hobby at $32 a month for 500 credits, which covered their volume with headroom. Knowledge base setup took 6 hours of my time. Total monthly cost: $32. Total first month cost including build: $750. Hobby now includes 700 credits.

Scenario 2: Mid market ecommerce, 1,800 conversations a month

The client was on Tidio for live chat at $89 a month and wanted to add an AI agent to handle order status, shipping, and returns. We added Lyro at the Growth tier for $49.17 a month annual, plus a custom Shopify integration that took 12 hours of my time. Combined platform bill: $138 a month. Build cost: $1,800. They saved an estimated 24 hours a week of human chat time, which they redirected to outbound sales.

Scenario 3: B2B SaaS, 7,200 resolutions a month

The client started on Intercom Advanced ($85 per seat for 8 seats = $680) plus Fin at $0.99 per resolution. At 7,200 monthly resolutions Fin alone was $7,128, bringing the combined Intercom bill to $7,808 a month. We rebuilt their support flow on a custom RAG agent on AWS Bedrock with Claude Haiku 4.5, kept Intercom for the inbox at the Essential tier ($29 x 4 seats = $116), and pointed the agent at their docs. New monthly cost: $116 (Intercom) + $620 (Bedrock + DynamoDB + S3 Vectors) = $736 a month. Build cost: $11,000. Payback: 7 weeks. Intercom's list prices have moved since: as of October 2026 Essential is $19 per seat billed annually or $29 monthly (one version of the page shows $29 and $39), and Advanced is $85 annually or $99 monthly.

Decision framework: which AI chatbot pricing model wins for your volume?

This is the framework I walk every client through on the first call. Answer four questions and the right pricing model usually picks itself.

1. How many monthly conversations or resolutions do you expect? Under 500: flat tier (Tidio, Crisp Mini, Chatbase Hobby). 500 to 5,000: per message credit (Chatbase Standard) or flat tier (Botpress Plus, now priced per conversation). Over 5,000: custom build or per seat (Zendesk + Copilot), almost never per resolution.
2. How many human support agents will use the system? Zero or one: pick a flat tier platform with no seat fees. Two to ten: per seat is fine if you negotiate. Eleven or more: per seat starts to bite, evaluate custom build.
3. How seasonal is your volume? Predictable: per credit or per resolution can work. Spiky: flat tier or custom build only, otherwise overage will eat you.
4. How specific is your knowledge base? Generic FAQs: any platform works. Highly specific data, regulated industry, sensitive PII: custom build on Bedrock or self hosted.

If you want me to walk through your specific case, take the AI readiness assessment first. It will tell you in 5 minutes whether you are ready to deploy and which pricing model fits.

Worked estimate: a site with 50,000 visits a month

People often ask what a chatbot costs on a site with 50,000 visits a month. The answer depends on how many visitors start a chat, which I cannot know for your site, so here are three cases at 1, 2, and 4 percent: 500, 1,000, and 2,000 conversations a month. Those start rates are my assumptions, not measured figures. I also assume Fin resolves half of the conversations, the rate one customer quotes on Intercom's pricing page, and I price two Intercom Essential seats at $19 on annual billing. The custom build line is model fees at Claude Haiku 4.5 prices, using the token model from the Botpress section, plus the $300 infrastructure floor from the table at the top. The build section's $200 to $800 infrastructure range already includes model fees, so the custom line is slightly high. The Intercom line rises by $20 a month if the page shows $29 seats. No line includes build cost, time spent maintaining the knowledge base, or the human agents who answer the conversations the bot does not resolve.

Per conversation, Intercom stays between $0.51 and $0.57 at every volume because Fin bills each outcome, Botpress falls from $0.69 to $0.50, and the custom build falls from $0.66 to $0.21 as the fixed $300 spreads across more conversations. The custom build also carries a one time cost of $5,000 to $50,000. At the $5,000 low end it does not pay back in any useful time at 500 conversations, takes about 28 months against Intercom and 16 months against Botpress at 1,000, and about 8 months against either at 2,000. If you want to see how the human side of that comparison works, AI agent vs live chat customer service covers it.

When the math stops working

Per resolution pricing breaks at scale. Per seat pricing breaks when you scale headcount. Per credit pricing breaks on viral spikes. Knowing where each model breaks down lets you avoid the trap before you sign.

The B2B SaaS client I described earlier was a textbook case. Intercom Fin at $0.99 per resolution looks reasonable at 500 resolutions a month ($495). At 5,000 it is $4,950. At 10,000 it is $9,900. The pricing scales linearly with success, which sounds fair until you realize the marginal cost of an LLM API call at that volume is closer to $0.02. The vendor is keeping $0.97 per resolution as margin. A whole conversation is several calls: on my token model in the Botpress section it costs about $0.06 in model fees on Claude Haiku 4.5 and about $0.01 on Haiku 5.5, which is the fairer comparison with a $0.99 resolution. At a certain volume that math becomes impossible to defend internally and you either build custom or you cap usage artificially.

The HVAC client I deployed for last quarter hit a different wall. They were on Crisp at $45 a month for two seats. They hired three more agents, which jumped them to a $295 a month tier (Plus is the only tier that supports unlimited agents and AI). They were paying for AI features they did not yet use. We moved them to Botpress Plus at $79 a month plus about $40 in AI spend, and they kept Crisp Free for the website widget. Total: $164 a month. Saved: $131 a month. My healthcare and home services automation page has more on this kind of consolidation play.

Those were the Crisp and Botpress prices at the time. As of October 2026 Crisp Mini includes four seats and Essentials includes ten, with AI credits on every paid tier, and a new Botpress Plus workspace is $150 a month billed annually with AI usage included, so the same consolidation would price differently today.

FAQ: AI chatbot pricing in 2026

What is the cheapest AI chatbot you can actually run a business on?

Chatbase Hobby at $32 a month billed annually ($40 monthly) or Tidio Starter at $24.17 a month annual ($29 monthly) are the two cheapest credible options for businesses doing under 100 monthly conversations. Free tiers exist (Botpress Free, ManyChat Free, Crisp Free) but every one of them caps at limits that production traffic will blow through inside a month.

Is per resolution pricing always more expensive than per seat?

No. Per resolution wins at low volume because you pay nothing for tickets the bot does not handle. It loses at high volume because the marginal cost stays $0.99 forever even when the model fees behind each resolution are a small fraction of that price. The crossover point is usually around 1,500 to 3,000 resolutions a month depending on seat count.

How much does ChatGPT Enterprise cost compared to a dedicated chatbot platform?

ChatGPT Enterprise pricing is custom and OpenAI does not publish a list price. Any per seat figure you see online is a third party estimate that OpenAI has not confirmed, so ask sales for a quote before you plan around one. It is a general purpose assistant, not a customer facing chatbot. For a customer support or sales chatbot you still need a platform like Intercom, Tidio, or Chatbase on top, which adds $50 to $400 a month minimum.

Should I choose monthly or annual billing for an AI chatbot?

Start monthly for the first 60 days. Annual saves 17 to 30 percent but locks you in. I have seen too many clients commit annually to a platform that turned out wrong for their workflow and lose 6+ months of unused subscription. Validate fit first, then convert to annual.

What does it actually cost to build a custom AI chatbot in 2026?

Build cost ranges from $5,000 for a single use case (lead qualification on a website) to $50,000 for a multi channel agent with CRM, calendar, and helpdesk integration. Infrastructure cost runs $200 to $800 a month on AWS Bedrock or $150 to $600 a month on OpenAI for typical small business volume. The math wins above 3,000 monthly conversations or when data sensitivity rules out off the shelf platforms.

How do I avoid overage fees on per credit AI chatbot platforms?

Three tactics work. First, set hard caps in the platform's admin panel rather than trusting yourself to upgrade in time. Second, build a fallback flow that hands off to a human form when the bot hits its limit, instead of failing silently. Third, monitor weekly, not monthly, so a viral moment does not blow your budget before you notice.

Are free AI chatbots actually viable for small businesses?

Free tiers are useful for testing and for businesses with truly tiny volume (under 25 active contacts for ManyChat, or 100 conversations a month on Botpress Free). For any real customer facing deployment you will outgrow the free tier in the first 30 days. Budget for the cheapest paid tier from day one.

What hidden cost surprises clients the most after they sign?

The cost of maintaining the knowledge base. Most clients budget for the platform fee and forget that someone has to keep the bot's training data current. For a small business that is 4 to 12 hours of internal time per month. At an internal labor rate of $50 to $100 an hour, that is another $200 to $1,200 a month in real cost that never appears on the vendor's invoice.

The real answer to "what does an AI chatbot cost?"

The right AI chatbot pricing for your business depends on three things: your monthly conversation volume, the specificity of your data, and how predictable your traffic is. For most small businesses under 500 monthly conversations, Tidio or Chatbase at $24 to $120 a month is the sweet spot. For mid market companies with moderate volume and existing helpdesk infrastructure, Zendesk or Intercom at $200 to $800 a month is usually the right call. For high volume companies where per resolution math stops making sense, you build custom on Bedrock or OpenAI for $300 to $1,000 a month in infrastructure plus a one time build cost.
