What is needed to determine if a purchase order is authorized?

To determine if a purchase order is authorized, the purchaser's signature serves as a critical indicator of authorization. This signature typically signifies that the individual responsible for the transaction has formally approved and accepted the terms of the purchase order. It establishes a clear, accountable link between the financial commitment made by the organization and the authorized personnel.

While other elements like agreement information, the requisitioner's signature, or approval by the requisitioner can provide context or additional validation of the order, they do not carry the same weight of authorization as the purchaser's signature. The purchaser’s signature directly indicates that the person authorized to make purchasing decisions has reviewed and accepted the order, ensuring that it aligns with company policies and budget constraints.
