Three everyday cases, step by step. They are illustrations of how we work, not client stories.

  6. Done. It is held under your number until tomorrow at closing time. Anything else?
  7. Do you also do alterations?
  8. That is not in the shop’s information. It does not guess.
  9. I don’t have that information. I’ll pass your question to the team and they will reply here.

  1. Where is my order? It was supposed to arrive yesterday.
  2. Finds the order by the customer’s phone number and reads its status.
  3. I found it: the order left the warehouse this morning and is on today’s route, with delivery expected before 2 pm. I’m sorry for the delay.
  4. I need it before noon or I can’t open.
  5. A promise it cannot make by itself. It alerts dispatch with the order and the deadline.
  6. I can’t promise that myself. I have alerted dispatch with your deadline, and a person will confirm here in a few minutes.
  7. Marta · DispatchThis is Marta from dispatch. I moved your delivery to the first stop. It will be there by 11.

A distributor: where is my order?

The agent reads the order system, tells the truth about a delay, and alerts a person when a promise is needed.

What happens behind

  1. Customer
  2. Agent
  3. Order system
  4. Dispatch

What we test before launch

  • It reads the status from the order system and never guesses.
  • It does not promise delivery times it cannot keep.
  • A late order raises an alert to a person, with the order attached.
  • It apologises once, plainly.

In every case the rule is the same: the agent does the routine part, and a person decides the rest.

On this site

This site’s own agent, and how we test it.

The chat on this page is a small agent built the same way. Before it went live, and after every change, it has to pass these checks with real questions.
