AI agents explained: what they are and what they do

What exactly is an AI agent?

An AI agent consists of a few parts that work together:

• A language model, such as the models behind ChatGPT or Claude. That's the brain that understands the task and makes a plan.
• Tools: connections to other systems, such as your inbox, calendar, CRM or accounting software. They let the agent do things instead of just talking.
• Memory: information about earlier steps and about your business, so the agent knows where it left off.
• A goal and rules: what needs to be achieved, and what the agent may and may not do on its own.

The difference from fixed automation is that an agent doesn't follow a rigid step-by-step plan. It chooses which step makes sense. If it gets unexpected information, it adjusts its plan.

An example. You give an agent the task: 'make sure this customer gets a quote for three workstations'. The agent looks up the customer in your CRM, checks which products fit, fetches the current prices, drafts a quote and asks you for approval. If information is missing, such as the delivery address, it asks that question first.

Chatbot vs automation vs AI agent: the difference

These three terms are often mixed up. Here's how they differ:

• Chatbot: answers questions in a conversation. Handy for customer service, but usually doesn't do anything in your systems itself. See also a chatbot on your website.
• Fixed automation: always performs the same steps when something happens. For example: when a form comes in, create a customer in the CRM. Reliable and predictable, but not flexible.
• AI agent: gets a goal and decides the route itself. More flexible, but also less predictable. That's why an agent needs clear boundaries.

In practice, the best solution often sits between fixed automation and an agent. A regular integration handles the fixed steps, and AI only does the part that requires thinking, such as reading and understanding an email.

AI agent examples for small businesses

A few tasks an AI agent can already do well today, provided it's set up properly:

• Preparing quote requests: the agent reads the request, looks up the right products and prices and prepares a draft quote.
• Handling customer questions: the agent looks up the status of an order and suggests a reply, or creates a return.
• Scheduling appointments: the agent checks the calendar, suggests times and confirms the appointment once agreed.
• Processing documents: the agent reads an invoice or packing slip, checks it against the order and flags discrepancies.
• Research: the agent gathers information about a new customer or supplier and writes a short summary.

What these examples have in common: they're tasks that take a lot of time and are slightly different every time, but do have a clear goal. You'll find more ideas in our overview of AI for small businesses.

Where AI agents still fall short

AI agents are impressive, but not perfect. Keep these limitations in mind:

• They can make mistakes and sound confident about them. One wrong step can carry through into the next steps.
• The more steps a task has, the greater the chance something goes wrong somewhere.
• They need good, up-to-date information. With outdated prices or messy data, even a smart agent makes mistakes.
• Every step costs computing power, so an agent that does a lot of work also costs money on an ongoing basis.
• An agent with access to your systems must be well secured.

How to use an AI agent safely

A few fixed rules keep an agent under control:

• Start with a small, well-defined task, not with 'handle all my admin'.
• Give the agent only the permissions it needs. If it only needs to read, don't give it write access.
• Always have a person approve important actions first, such as an email to a customer, a payment or a deletion.
• Keep a log of everything the agent does, so you can see what happened.
• Mind privacy: which personal data does the agent see? Also read AI and the GDPR.
• Test with real examples before you let it run live.

Also consider the European AI Act. If you let an agent make decisions about people, for example in recruitment, stricter rules apply. For most small business tasks, an agent that prepares and a person who decides is the safest choice.

Having an AI agent built: how to approach it

A good agent doesn't start with technology, but with your process. Which task takes a lot of time? Which steps do you take? Which systems do you use? And where do you want to keep the decision yourself? Only once that's clear do you choose the tools. Often it turns out that part of it can be done with a regular integration, and AI is only needed for the tricky part. That's cheaper and more reliable.
