Who is responsible for monitoring and reporting GPC usage?

The responsibility for monitoring and reporting GPC usage primarily falls on the contracting officer or designated official. This role is critical because these officials are tasked with ensuring compliance with applicable regulations and policies regarding the use of Government Purchase Cards. They are responsible for overseeing the activities related to the card’s usage, including reviewing transactions, ensuring that purchases are legitimate, and that they align with the agency's procurement policies.

The contracting officer or designated official plays a vital role in mitigating risks associated with improper usage of the GPC, such as unauthorized purchases or exceeding spending limits. They also compile necessary reports and data that reflect the usage patterns and help in identifying any areas for improvement or required training.

In contrast, the other options do not encapsulate the formalized responsibility and oversight that the contracting officer or designated official has in this matter. The general public does not have a role in the internal monitoring of GPC usage, a cardholder may be involved in day-to-day spending but lacks the oversight capacity, and any employee in the department does not inherently possess the responsibility for this specific task without appropriate designation or training.
