Explain why a bill went up, from the customer's own usage

In short

A customer asks why their bill is higher. Rendel reads the bill and the usage from your API and answers with the difference, the items that caused it, and what they can change.

From the customer's own data

The figures come from your API, so the answer is about this customer's bill, not a help article about bills in general.

In Kestrel, a demo app

Asked: “Why is my bill higher this month?”

Answered: Your October bill is €53.40, €18.00 more than in September, because of calls to Germany and roaming in Greece.

Questions

  • If you give it a plan-change action, yes, after the customer confirms on a card.

See Rendel do this in an app like yours.

Rendel is an AI assistant inside your own app. Customers ask in their words, and the order is tracked, the card frozen or the return started right there, without a support ticket.
