Which item is included as a requirement on a purchase order?

• A. Ship To location.
• B. Pre-Printed Sequence Number to keep track of order.
• C. Space for the supplier's/vendor's name and address.
• D. The firm's name and billing address, telephone number, fax number, and e-mail address of an appropriate party.

Answer: (B)

Tracking and documentation in purchase orders rely on having a unique identifier for each order. A pre-printed sequence number serves as that identifier, giving every order a distinct code to reference during receiving, invoicing, and payment. This makes it possible to reconcile what was ordered with what was delivered and what was billed, and to maintain a clean audit trail. While ship-to location, vendor details, and the buyer’s contact information are standard and necessary for handling the order, they don’t by themselves ensure traceability across the procurement process in the same way the PO number does. The sequence number is the essential mechanism that enables precise tracking of each individual order.
