The AP invoice includes the vendor’s name, address, and contact information, as well as the details of the goods or services provided, the quantity, the unit price, and the total amount due. It also includes the payment terms, such as the due date and any discounts that may be applied. The AP invoice is an important document for both the vendor and the business, as it serves as an official record of the transaction and helps to ensure that payments are made on time.
