An invoice is a bill detailing services rendered or products purchased and their overall cost. As a legal document, an invoice can be used as evidence of an incurred debt. An invoice may cover the costs of newly purchased equipment.
In certain cases (especially when it is signed by the seller or seller's agent), an invoice serves as a demand for payment and becomes a document of title when paid in full. Types of invoice include commercial invoice, consular invoice, customs invoice, and pro forma invoice.
