      description: An Invoice is a financial statement issued by a creditor to a debtor
        that itemises the amounts owed and records how they are settled. Each line item
        is a billed financial entry — an order, refund, commission, finder fee, or
        adjustment — rather than a product or service. The invoice tracks its lifecycle
        status, the agreed settlement terms, and the proofs of settlement (payment
        actions) that discharge the amount due. An invoice may be issued, updated,
        settled, cancelled, or disputed over its lifecycle.
