What is one of the primary uses for a purchase order?

A purchase order is primarily used to request shipment of merchandise from a vendor. It serves as a formal document that a buyer sends to a supplier, indicating the types, quantities, and agreed prices for products or services. This document not only initiates the transaction but also establishes a clear record of what has been ordered, which helps both parties manage inventory and resources effectively.

By issuing a purchase order, the buyer ensures that the vendor has the necessary information to process the order, fulfill it accurately, and ship the specified items. This is crucial for maintaining strong supplier relationships and ensures that both parties are on the same page regarding expectations, terms, and delivery timelines.

The other options do not align with the primary function of a purchase order. For example, recording sales growth pertains to sales analysis and performance metrics, confirming arrival relates to receiving procedures, and documenting customer complaints is focused on customer service rather than procurement. Thus, the role of a purchase order is specifically oriented toward the acquisition and shipment of goods.
