Answer

Ask a question to begin.

The account and the two periods select which invoices are compared. The question text shapes the wording of the explanation, not the arithmetic — the comparison is computed by billing_compare_invoices, never by the model. Every figure is validated against the evidence before it is shown; if validation fails the narration is withheld and the computed ranking is shown instead.
