Accounts Payable Invoice is essentially an invoice created when a company purchases goods or services. It is typically used to record the details of the transaction, such as the vendor, product/service purchased, quantity, price, and payment terms. This type of invoice is generally issued by the buying organization and received by the selling organization. On the Accounts Payable Invoice, the buyer must include their name, address, contact information and invoice number to ensure that it is properly tracked and processed. The Accounts Payable Invoice must be paid in full within the specified period outlined on the invoice for it to be considered valid.
