"Should we build an AI agent or a chatbot?" A question we get asked more and more. The terms get used interchangeably, but the difference determines what you get, what it costs, and whether it actually works for your use case.
Chatbot: scripted, predictable, cheap
A chatbot follows predefined paths. A customer types something, the bot recognises the intent, and returns a canned answer or triggers a fixed process. Think of an FAQ bot on your website or a lead form that asks smart follow-up questions.
Characteristics:
- Limited tasks (Q&A, forms, simple routing)
- Predictable output
- Fast to build — often in days
- Low cost — usually €1,500 to €5,000 for a solid implementation
- Works well at high volume and low complexity
AI agent: autonomous, reasoning, more powerful
An AI agent has a goal and the tools to reach it. It uses a large language model (such as Claude or GPT-4) to decide which steps to take, which tools to call, and how to respond to unexpected situations.
Examples from our own practice: an agent that reads email, prioritises it, and drafts replies. An agent that assembles quotes by combining your CRM, product database, and historical deals. An agent that researches a new account and delivers a complete sales briefing.
Characteristics:
- Complex, multi-step tasks
- Integration with multiple systems (CRM, ERP, email, calendar)
- Adapts to new situations
- Higher cost — usually €5,000 to €25,000 for a production-grade agent
- Requires monitoring and governance — see our EU AI Act compliance offering
When to choose which?
In short:
- Choose a chatbot if your use case consists of predictable interactions with a clear path. FAQ, lead capture, simple triage.
- Choose an AI agent if the task has multiple steps, requires judgment, or needs to integrate with multiple systems.

The middle ground: agent-augmented chatbot
In practice we increasingly see hybrids. A chatbot handles 80% of standard questions — fast, predictable, cheap — and escalates the complex 20% to an AI agent. That gives you the best of both worlds without unnecessary cost on simple cases.
Key takeaway
The right choice depends on the complexity of your task — not on what sounds most "modern". A well-built chatbot can be a better solution than a mediocre agent.

Frequently asked questions
When should I choose a chatbot and when an AI agent?
Choose a chatbot if your use case consists of predictable interactions with a clear path, such as FAQ, lead capture or simple triage. Choose an AI agent if the task has multiple steps, requires judgment, or needs to integrate with multiple systems such as CRM, ERP or email.
What does a chatbot or AI agent cost for an SMB?
A solid chatbot implementation typically costs €1,500 to €5,000. A production-grade AI agent typically costs €5,000 to €25,000, depending on complexity and the number of systems it needs to integrate with.
Can you combine a chatbot and an AI agent?
Yes. In practice we increasingly see hybrids: a chatbot handles the standard questions — fast, predictable, cheap — and escalates the more complex cases to an AI agent. That gives you the best of both worlds without unnecessary cost on simple cases.
