A simple AI chatbot for basic Q&A typically costs $800 to $2,500 to set up, with ongoing costs of $50 to $200 a month. A more advanced chatbot with CRM integration, lead qualification, and calendar booking generally runs $2,500 to $7,000 to build, with $150 to $500 a month in ongoing costs. Highly custom, multi-integration chatbots can run higher still. The next sections explain what drives that range and which questions change the number a provider quotes you.
Simple vs advanced chatbots
A simple chatbot answers common questions from a defined knowledge base — your FAQs, policies, and service information — and captures basic contact details. It's essentially a well-organised, conversational front door to information a visitor would otherwise have to hunt for across your website. An advanced chatbot goes further: it qualifies leads through multi-turn conversation, integrates directly with your CRM and calendar, personalises responses based on who it's talking to, and can hand off seamlessly to a human with full context rather than making the visitor repeat themselves. The gap in cost between these two categories almost always comes down to how much logic, memory, and integration sits behind the conversation, not how "smart" the underlying language model itself is.
Setup costs
Setup covers building and training the chatbot on your specific business information, designing the conversation flow, and testing it against realistic scenarios — including the awkward, off-script questions real visitors actually ask, not just the tidy examples used in a demo. This is typically the largest one-off cost and scales with how much custom logic and integration work is involved. A chatbot answering FAQs from a static knowledge base is a relatively contained build; one qualifying leads through a multi-step conversation and routing different answers to different CRM fields is a considerably larger scope of work, even though both are technically "a chatbot."
AI model costs
Most AI chatbots run on a pay-per-use language model behind the scenes, so ongoing costs scale with conversation volume — a chatbot handling a handful of conversations a day costs very little to run; one handling hundreds scales up accordingly, though usually still remains modest per conversation. As a rough sense of scale, a chatbot handling a few hundred conversations a month on a well-configured setup often costs the business only a small fraction of what a single missed or delayed lead would have cost in lost revenue, which is part of why the model economics tend to work in the business's favour even at moderate volume.
Integration costs
Connecting the chatbot to your CRM, calendar, and any other business systems adds setup cost but is usually where the real efficiency gains come from — a chatbot that can't actually book an appointment or log a lead is far less valuable than one that can. A chatbot that answers questions well but still requires a staff member to manually copy details into the CRM afterward has only solved half the problem; the integration work is what turns a conversational FAQ into something that actually reduces admin load on your team.
Ongoing costs
Beyond model usage, factor in any chat platform subscription fees and periodic maintenance — updating the chatbot's knowledge as your services, pricing, or policies change. A chatbot is not a "set and forget" tool: pricing changes, seasonal promotions, and new service offerings all need to be reflected in what it tells customers, and a chatbot running on stale information can create as much friction as it removes if a customer is quoted an outdated price or told about a service you no longer offer.
Example budgets
| Chatbot type | Typical setup cost | Typical monthly cost |
|---|---|---|
| Basic FAQ/Q&A chatbot | $800 – $2,500 | $50 – $200 |
| Lead qualification + booking chatbot | $2,500 – $7,000 | $150 – $500 |
| Custom multi-integration chatbot | $7,000+ | $500+ |
These ranges assume a reasonably well-scoped project. Costs move toward the top of each range when the business has multiple service lines with different qualification logic, needs the chatbot to operate across multiple languages, or requires integration with several separate systems rather than one primary CRM.
Build vs off-the-shelf platforms
Some providers build a chatbot on a fully custom stack, while others configure a commercial chatbot platform with your specific business logic layered on top. The off-the-shelf route is usually faster and cheaper to launch, since much of the underlying infrastructure already exists, but can hit limits if your qualification logic or integration needs are unusual. A custom build costs more upfront but avoids being constrained by a third-party platform's roadmap or pricing changes down the line. Most small to mid-sized businesses are well served by a configured commercial platform; a fully custom build tends to make sense only once conversation volume or integration complexity genuinely justifies it.
ROI calculation
The simplest way to think about ROI: how many leads or enquiries currently go unanswered outside business hours, and what's even one of those worth if converted? For most service businesses, capturing even a handful of extra qualified leads a month easily covers the ongoing cost of a well-built chatbot. Consider a trades or professional services business where an average new client is worth several hundred to several thousand dollars — even one additional booked job a month from after-hours enquiries that would otherwise have gone to a competitor who answered first can outweigh the entire monthly running cost several times over. See our broader guide on AI automation costs for how this compares to other automation investments.
Hidden costs to watch for
A few costs are easy to overlook when comparing quotes. Fallback handling — what happens when the chatbot can't answer, and whether that's built cleanly into the setup fee or billed as an extra — is one. Knowledge base updates as your pricing or services change are another, and it's worth clarifying upfront how many updates are included before extra charges kick in. Finally, check whether the quoted price includes testing against realistic, messy real-world questions, or only against the tidy set of examples used in the sales demo — the gap between those two things is often where a chatbot's real quality shows up after launch.
What to ask a provider
Before committing, ask: what happens when the chatbot doesn't know an answer (does it escalate cleanly to a human, or make something up)? Is pricing based on conversation volume, and what happens if volume spikes unexpectedly during a busy period or campaign? What's included in ongoing maintenance versus billed as extra — updating the knowledge base, adjusting conversation flows, fixing integration issues? It's also worth asking to see the actual conversation logic for a handful of tricky real-world scenarios before signing off, rather than only reviewing a polished demo conversation.

FAQs
How much does a website chatbot cost? Basic chatbots typically cost $800 to $2,500 to set up with $50 to $200 a month in ongoing costs; advanced chatbots with CRM integration and lead qualification run $2,500 to $7,000 with $150 to $500 a month ongoing.
Are AI chatbots expensive to run? Generally no — most run on usage-based AI model pricing that stays modest unless conversation volume is very high, and the labour savings and captured leads usually outweigh the running cost by a meaningful margin.
What affects chatbot development cost? The complexity of the conversation logic, the number of system integrations required, and whether it needs custom qualification or personalisation logic beyond basic Q&A are the three biggest cost drivers.
