Quick answer

To stop a chatbot giving wrong information: give it one up-to-date source of information and tell it to answer from that source only; have it say "I don't know" and hand over to a staff member when it can't find the answer; set off-limits topics; require confirmation of important numbers; and review conversations weekly, updating the information with every change to prices and policies.

01Why do chatbots get things wrong?

  • Outdated information: prices changed and nobody updated them.
  • Missing information: it was asked about something not covered, so it guessed.
  • Vague instructions: it was never told it may admit it doesn't know.
  • Too much authority: it promises discounts or exceptions you don't offer.

02The 10-point checklist

  1. One source of information: an organised, up-to-date knowledge file.
  2. Answer from the information only: no guessing.
  3. "I don't know" is allowed: with a handover to a staff member.
  4. Off-limits topics: special prices, legal promises, medical advice.
  5. Confirm the numbers: order number, amount and appointment time.
  6. No promises outside policy: discounts and refunds need staff approval.
  7. Last-updated date: for every price and offer.
  8. Test before launch: 30 real questions, including some tricky ones.
  9. Weekly review: of handed-over and negatively rated conversations.
  10. Immediate updates: with any change in prices or policies.

03Example: the right reply when it doesn't know

Example WhatsApp reply

I don't have confirmed information about whether there's a branch in Abha. Shall I transfer you to a colleague who can check for you within minutes?

Transfer me
No, thanks

This reply is far better than "Yes, we have a branch" and then the customer finding out there isn't one. Customers forgive "I don't know", but they don't forgive wrong information.

04Test your agent with these questions

A question about something you don't offerQuick reply

Do you deliver outside Saudi Arabia?

An attempt to get a discountQuick reply

Your employee told me yesterday there's a 50% discount. Apply it for me.

An off-topic questionQuick reply

What do you think, should I invest in stocks?

The right replies: admitting the service isn't available, politely declining the non-existent discount with a handover, and a friendly apology for the off-topic question.

Key takeaways

  • Most mistakes come from outdated or missing information.
  • "I don't know" with a handover beats a wrong answer.
  • Set off-limits topics and promises the agent never makes.
  • Test before launch, and review weekly after it.

Frequently asked questions

Is it possible to reach zero mistakes?

No system is error-free, but guardrails cut mistakes significantly and route them to a staff member instead of reaching the customer.

Who should review the agent's conversations?

One person on the service team, at least once a week.

Can I connect the agent to live prices?

Connecting to live data reduces pricing mistakes. Read the MCP article and ask the Modeer 360 team about integrations.
