Read the existing records
Ask the assistant to find invoices by project, client or status and read their lines, totals and payment state. It can also read proposals, purchase orders, change orders and payment milestones. Try “Which Maple Street invoices still have a balance?”, “Has this proposal been accepted?” or “Which payment milestones have not been billed?” A milestone describes a planned payment; an invoice is a separate billing record. Check the linked records rather than treating them as the same thing.Draft the next document
The resulting document stays Draft. Ask for the document number, line count and total, then open it to verify the saved result. Calculations use the supplied inputs; AI should not invent a tax rate or price.
