What does an AI chatbot for your own website cost?

A AI chatbot answers questions on the company’s own website – ideally from the company’s own documents, not from the general internet. The costs depend on three factors: the scope of the knowledge base, the frequency of changes to these documents and the scope of functions beyond simple answering.

Cost driver 1: The knowledge base

A chatbot is only as good as the documents it uses to answer. The effort rarely comes from the “training” itself, but from the cleanup beforehand: Which documents are current, which contradict each other, which may be answered at all? Companies with well-maintained documentation start at a lower cost than companies where knowledge is spread across folders and people.

Cost driver 2: How often content changes

Prices, opening hours, services, and availability change at different rates. The more often they change, the more important an automated process, keeping the knowledge base up to date – otherwise the bot will eventually and reliably answer with outdated information. This maintenance path is a real cost factor and is regularly underestimated.

Cost driver 3: What it should do besides answering

• Only provide information – the leanest and most cost-effective option
• Capture and route inquiries in a structured way
• Suggest appointments or book them directly
• Look up information in existing systems, for example an order status

Each level increases setup effort, but also saves more working time. The sensible starting point is almost always the lowest level, supplemented by structured request intake.

The right benchmark

Here too, the comparison is not “chatbot versus zero,” but chatbot versus the current effort. Repeated questions by email and phone already cost working time today — they just do not appear on any invoice. That is why a reliable calculation starts by recording the ten most frequent questions and how often they occur.

By the way: The Consulting and guided implementation of such assistants is eligible for funding. Through INQA-Coaching 80% of consulting costs are covered, up to €11,520. Funding applies to the implementation, not the software itself – the funding check shows in just a few minutes what is eligible for you.

Frequently asked questions about the cost of an AI chatbot

Why is there no fixed price here?

Because the effort depends largely on the condition of your documents and the desired scope of functions. A bot that answers from a well-maintained FAQ can be set up quickly; distributed, contradictory knowledge requires preparatory work.

Can I start small?

Yes, and that is the recommended approach. Start with the most common questions and a clear handoff to humans for everything else. The scope can be expanded later.

Is the chatbot itself eligible for funding?

Not the software, but the consulting and guided implementation do. Through INQA-Coaching, 80% of the consulting costs are covered, up to €11,520.

What does maintenance cost?

That depends on how often your content changes. What matters is to think about the update process from the start – setting it up later is more time-consuming than doing it right at the beginning.
