Search for "chatbot costs" and you'll mostly find price lists from platform vendors — which naturally tell only half the story. Here's the honest market overview, including the costs that don't appear on any pricing page.
The three price classes on the market
Builder bots (€10–100 per month). Rule-based bots that react to keywords with canned answers. Cheap — and they feel exactly that way: phrase a question differently than anticipated and you hit a dead end. Fine for simple FAQ routing, usually a disappointment for real customer service.
SaaS AI platforms (€500–2,500 per month). The established vendors deliver real AI chatbots as a subscription — plus one-time setup that runs between €2,000 and €15,000 depending on complexity. This works, but has two catches: the costs run forever, and the bot isn't yours. Cancel the subscription and your customer-service knowledge is gone.
Your own AI assistant (one-time, plus API costs). The third option is rarely advertised because nobody earns a subscription from it: an assistant built on your content that belongs to you, whose running costs consist only of actual usage. Setup is a manageable project; at typical SMB volume, operation sits in the double-digit euro range per month — not four digits.
The hidden costs nobody mentions
Whichever route — these items rarely appear on price lists:
- Content maintenance. A bot is only as good as the knowledge behind it. When products, prices or processes change, the knowledge has to follow — otherwise it confidently answers wrong.
- Integrations. "Can the bot also look things up in the order system?" — it can, but the connection is its own effort. Clarify before, not after.
- Escalation. The handover to humans (mail, ticket, callback) decides whether the bot helps customers or infuriates them. Good escalation costs concept work.
- Agent licenses & volume limits. On SaaS platforms, additional team members and higher chat volumes cost extra — the entry price is rarely the final price.
The honest math
Don't compare monthly prices — compare total cost over three years: a platform at €800 per month is close to €30,000 plus setup — and in the end you own nothing. Your own assistant costs a fraction of that once, and the running costs scale with usage instead of contract duration.
The counter-question is part of honesty too: if your team only gets a handful of requests per week, you probably don't need a chatbot at all — you need a good FAQ page.
What an assistant should be able to do
What an AI assistant looks like that genuinely answers customer questions — with your knowledge, in your tone, with clean human handover — is shown at AI for customer service. And if you want to know what your specific case would cost: ask us — you'll get a fixed price instead of a subscription trap.
