What document outlines the policies and procedures for GPC usage?

The GPC operating procedures document is the definitive source that outlines the specific policies and procedures for the usage of the Governmentwide Commercial Purchase Card (GPC). This document is designed to provide clear guidance to cardholders and approving officials regarding the authorized uses of the GPC, responsibilities of users, spending limits, and compliance requirements. It is essential for ensuring that all transactions conducted with the GPC align with federal regulations and DoD standards, thereby minimizing the risk of misuse or fraud.

While the other options may contain relevant information, they do not specifically provide the comprehensive framework focused on GPC usage as clearly as the GPC operating procedures document does. For example, the operations manual of credit cards may address a broader range of credit card types and uses rather than the specific context of the GPC. Similarly, the financial regulations handbook and internal compliance guidelines are more generalized resources that might not delve into the specifics of GPC processes and procedures. Thus, the GPC operating procedures document serves as the primary authoritative source for understanding how to appropriately utilize the GPC within the Department of Defense.
