AI agent: simple definition, examples and costs for an SMB

In brief

An AI agent is a program that, unlike a chatbot, doesn't just answer: it executes actions (qualify a case, follow up with a client, extract data, connect your tools). It's the difference between an assistant that talks and an assistant that acts.

• An agent reads data, makes decisions according to your rules, and chains actions in your tools.
• It's supervised: activity logs, dashboards, escalation to a human when needed.
• Unlike no-code, it's production code, robust at scale.
• For an SMB, an agent's operating cost runs around 5 to 30 €/month depending on volume.

The problem, concretely

Your teams spend hours on repetitive tasks: sorting cases, following up with clients, re-entering data between two tools. An AI agent does these tasks in your place, following your rules, 24/7, without entry errors. Humans keep supervision and sensitive decisions.

Chatbot vs agent: the difference

A chatbot answers questions (it reads your documents and cites its source). An agent goes further: it reads, decides and acts in your tools (qualification, follow-up, extraction, CRM update). An agent can even use a chatbot to answer, but it adds action.

Concrete examples for an SMB

• Case qualification: the agent reads the documents, applies your criteria, classifies and passes along.
• Follow-ups: quotes, unpaid invoices, missing documents: the agent follows up at the right time, with the right tone.
• Extraction and entry: it reads a document and updates your CRM or spreadsheet.
• Summaries: it summarizes meetings and documents, with the actions to keep.
