Final answer:
Validating a vendor invoice involves multiple steps, all of which are essential. The correct option is: 5) None of the above
Step-by-step explanation:
In a typical, efficient AP/CD process, the step of "validating" a vendor invoice includes reviewing the invoice for accuracy, verifying the vendor's information, matching the invoice to purchase orders and receiving documents, and approving the invoice for payment. Therefore, all of the given options 1) reviewing the invoice for accuracy, 2) verifying the vendor's information, 3) matching the invoice to purchase orders and receiving documents, and 4) approving the invoice for payment, are expected steps in validating a vendor invoice. Hence, none of the above applies as an exception.
