AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
UK consumer law applies to what an AI support agent tells customers exactly as it applies to a person: it must not misstate rights under the Consumer Rights Act 2015 or the 14-day cancellation rules, or mislead in ways the Digital Markets, Competition and Consumers Act 2024 prohibits. The safest set-up answers only from your written policies, states statutory rights accurately and hands disputes, complaints and exceptions to a person.
Your AI agent speaks for your business
When a customer asks your chat assistant whether they can return a faulty kettle, the answer is your business's answer. If the agent says no and the law says yes, you are responsible, not the software. Since April 2025 the Competition and Markets Authority can enforce consumer law directly under the Digital Markets, Competition and Consumers Act 2024, including fines of up to 10% of global turnover for serious breaches. Small firms are unlikely to be the first target, but the rules apply to them and to customers' own claims.
The rights an agent must never contradict
| Rule | What it gives consumers | What the agent must do |
|---|---|---|
| Goods: Consumer Rights Act 2015 | Goods must be of satisfactory quality, fit for purpose and as described | Never say a faulty item cannot be returned |
| Short-term right to reject | Usually 30 days to reject faulty goods for a refund | Offer a refund in this window for faulty goods |
| Repair or replacement | After 30 days, one repair or replacement before a price reduction or refund | Explain the next step accurately |
| Services | Must be performed with reasonable care and skill | Route complaints about quality to a person |
| Distance sales: Consumer Contracts Regulations 2013 | Usually 14 days to cancel most online or phone purchases, with exceptions | Apply the exceptions only as your policy sets them out |
| Unfair practices: DMCC Act 2024 | Bans misleading actions and omissions, aggressive practices, fake reviews | Never pressure, invent urgency or misstate terms |
Your own returns policy can be more generous than the law, never less. A common error is an agent trained on a policy that says no refunds after 14 days, which then tells a customer with a faulty item that they are out of luck. The agent should treat statutory rights as a floor it cannot go below, whatever the policy text says.
Pricing is another area where agents can slip. Under the DMCC Act, drip pricing, where unavoidable fees are revealed only late in the buying process, is treated as misleading. An agent quoting a price should give the total the customer will pay, including any mandatory charges, and should not invent discounts or deadlines to close a sale.
How to set up a support agent that stays inside the law
- Write the policy set first: returns, refunds, delivery, warranties, complaints. Have it checked against the law once.
- Load that set as the only source the agent may answer from, with each reply citing the clause.
- Set a confidence floor: below it, the reply goes to a person, not the customer.
- List the topics that always go to a person: disputes, injury or safety, vulnerable customers, chargebacks, legal threats.
- Tell customers they are talking to an AI and how to reach a person.
- Review a sample of conversations each week and fix the policy, not just the reply.
A worked example: an online furniture retailer
This is an illustrative example. A small furniture business in Norwich sells online and receives about 600 messages a month, mostly about delivery dates. The support agent answers delivery questions from the order system and the delivery policy, with the clause attached. A customer writes on day 22 that a chair leg has split. The agent recognises a fault within 30 days, states that the customer is entitled to reject it for a refund, and offers the options the policy allows. It books the collection request with a person, because arranging couriers is outside its scope.
A second customer, on day 40, wants to return a sofa because the colour does not suit the room. This is outside the 14-day cancellation period and not a fault. The agent explains the policy politely, does not invent an exception, and offers to pass the request to the owner, who decides to offer a goodwill exchange. The goodwill decision stays with a person.
Across both cases, the record matters. Each reply, the clause it relied on and the hand-over to a person were logged, so if the customer later complains, or takes a claim to the small claims court, the business can show exactly what it said and why.
Complaints handling itself deserves a clear route. Customers should be able to reach a person without repeating their story, and the agent should pass on the full conversation and order history. Measure how long escalated cases wait, not just how fast the agent replies, because a quick automated answer followed by a week of silence is worse than a slower human one.
Data protection and transparency
Customer conversations contain personal data, so UK GDPR applies. You need a lawful basis, a contract with any AI provider, and a privacy notice that explains the AI's role. Since February 2026 the Data (Use and Access) Act 2025 has changed the rules on solely automated decisions with significant effects: they are permitted in more cases, but with safeguards, including telling people and letting them ask for human review. Refusing a refund is unlikely to be significant in that legal sense, but a human route is good practice in any case.
Where Pryme fits
The Pryme Customer Support agent answers only from the policies you load, attaches the source to every reply, and sends anything below the evidence floor to a person intact with its history. It cannot grant an exception, move money or change a policy, and refunds within policy are booked with the Finance agent.

Questions people ask
Do I have to tell customers they are talking to an AI?
There is no single UK rule requiring it in every case, but being clear avoids misleading customers and supports transparency under UK GDPR. Most businesses say so at the start.
Can my AI agent refuse a refund?
It can apply your policy, but it must not refuse a refund the law requires, such as for faulty goods within 30 days. Disputed cases should go to a person.
What if the agent gives a customer wrong information?
Your business is responsible. Correct it promptly, honour statutory rights, and fix the source policy or rule that caused it.
Does the 14-day cancellation right apply to everything?
No. There are exceptions, such as personalised items and some perishable goods. Your policy should list them, checked by an adviser.
