what is an invoice #
An invoice is a commercial document that itemizes a transaction between a buyer and a seller. If goods or services were purchased on credit, the invoice usually specifies the terms of the deal, and provide information on the available methods of payment. An invoice is also known as a bill or sales invoice. BREAKING DOWN 'Invoice' Companies may opt to simply send a month-end statement as the invoice for all outstanding transactions. If this is the case, the statement must indicate that no subsequent invoices will be sent. An invoice must state it is an invoice on the face of the bill.
