Which of the following best describes an invoice?

Option B best describes an invoice. An invoice is a document that specifies the details of a transaction between a seller and a buyer. It contains information such as the quantity, description, prices, and total value of the goods or services being purchased. The invoice serves as a request for payment from the buyer to the seller. In other words, an invoice is a document that a seller sends to a buyer to request payment for goods or services that have been provided. The invoice specifies the terms of the transaction, such as the due date for payment, the amount owed, and the method of payment. It is an important document for both the seller and the buyer, as it helps to ensure that the transaction is properly documented and that both parties have a clear understanding of the terms of the sale. Therefore, option B is the correct answer.
