The best AI agent is the one that knows when to stop
Most AI customer service tools can hold a fluent conversation. That is no longer the hard part. What separates them is what happens at the edges: the question the agent has no approved answer for, the angry customer, the request to speak to a person. A good set-up answers the common questions well and hands over gracefully. Testing providers on your awkward questions, not their demo, is how you find it.

What to compare
- Where its answers come from. From a knowledge base you approve, or from anything it can find? The narrower the source, the fewer surprises.
- What it does when it does not know. A good agent says so and offers a person or a callback. Ask each provider to show you this happening.
- Which channels it covers and whether conversations from chat, WhatsApp and social messages land in one place for your team.
- How it connects to your systems, such as bookings, orders or a CRM, and what it can change rather than just read.
- What you can see afterwards: full transcripts, unanswered questions and hand-over rates, so you can improve it.
What has changed
Old-style chatbot or AI agent?
“Chatbot” covers two very different things. Know which one you are being sold.
| Feature | Rules-based chatbot | AI customer service agent |
|---|---|---|
| How it understands the customer | Buttons and keywords | Everyday wording, typos and follow-up questions |
| Where answers come from | Fixed replies written in advance | Your approved information, phrased to fit the question |
| Can it take action? | Rarely | Often, within your rules: book, check an order, take details |
| When it is stuck | Shows a menu again | Should say so and hand over to a person |
| Main risk | Frustrating dead ends | Confident answers you did not approve, if set up loosely |
Channels
Wherever customers message you
Website chat
A chat window on your site that answers questions, captures enquiries and offers bookings while visitors are still on the page.
WhatsApp and text
Many customers prefer to message. An agent can answer, book and send confirmations in the same thread.
Facebook and Instagram
Direct messages from social media answered from the same approved information as your website.
Email and forms
Often handled by an AI email assistant, ideally sharing the same rules and answers.

The work that matters
An agent is only as good as what you teach it
Whichever provider you choose, the quality of its answers comes down to the information you give it. Four steps, in this order.
- 1
Start with your real questions
Pull the twenty questions customers ask most from your inbox, phone notes and messages. Answer them properly once.
- 2
Add the facts it must get right
Opening hours, prices you publish, areas you cover, lead times, returns, cancellation terms. Keep them in one place you update.
- 3
Write the no-go list
Topics it must never answer on its own: complaints, refunds outside policy, medical or legal questions, anything about a specific account.
- 4
Decide the hand-over
When it passes to a person, how the customer is told, and what happens out of hours.
Guardrails
Treat it like a new member of staff
Customers will take what your AI agent says as coming from your business. So give it the same boundaries you would give a new starter on the front desk: what it can say, what it must pass on, and who it asks when unsure.
The Competition and Markets Authority is clear that a business is responsible for what an AI agent it uses does, even when someone else supplies the tool. Tell customers at the start that they are chatting with an AI assistant, and make it easy to reach a person.
You would not be alone: in September 2026, 30% of UK businesses, and 38% of those with ten or more employees, used at least one AI technology, according to the ONS.
What to measure in the first month
- How many conversations it resolves without a person
- How many it hands over, and why
- Questions it could not answer, to add to the knowledge base
- Bookings or enquiries it captured
- Complaints about the agent itself
What is an AI chatbot for business?
A chat assistant on your website or messaging channels that answers customer questions and captures enquiries. Older chatbots follow fixed scripts and buttons; AI agents understand everyday wording and answer from the information you give them.
Will it make things up?
It can, if it is set up loosely. Choose a provider that limits answers to your approved information, test it with awkward questions before going live, and make sure it says when it does not know.
Am I responsible for what the chatbot tells customers?
Yes. The Competition and Markets Authority’s guidance on using AI agents says that if an AI agent you use does something illegal, your business is responsible, even if a third party supplies the tool. Keep prices, terms and promises in its knowledge base accurate and up to date.
Can it hand over to a person?
Most can pass a conversation to your team in real time, or take details for a callback when nobody is free. Decide in advance which topics always go to a person.
Can it work on WhatsApp and Instagram?
Many providers cover website chat, WhatsApp and social messages from one set-up, so customers get the same answers wherever they ask. Check which channels each provider supports.
Can it take bookings or check orders?
Yes, if it connects to your booking or order system. Start with read-only tasks, such as checking availability, before letting it change anything.
Should customers be told they are chatting with AI?
Yes. Say so at the start of the chat. Being open about AI is expected good practice, and customers who know are less likely to feel misled when they ask for a person.
What about customer data?
Your business remains responsible for personal data collected in chats under UK GDPR. Check where transcripts are stored, for how long, and get a data processing agreement with the provider.
Is this the same as an AI receptionist?
Similar idea, different channel. An AI receptionist answers phone calls; a customer service agent answers messages. Many businesses use both, set up with the same rules. See our answering service comparison.
How long does it take to set up?
Most of the time goes into writing and checking the knowledge base, not the technology. A small business with clear answers to its common questions can be ready far quicker than one starting from scratch.
