What impact do GPC transactions have on government budget accountability?

The correct choice emphasizes that GPC (Government Purchase Card) transactions help maintain control and oversight over small expenditures. By allowing agencies to make small purchases quickly and efficiently, GPC transactions are designed with oversight mechanisms that ensure compliance with federal regulations. This enhances budget accountability, as GPC transactions typically involve predefined spending limits and require proper documentation and approval processes to confirm that expenditures align with budgetary constraints.

Maintaining control is crucial, especially since small purchases can accumulate and significantly affect overall spending if not monitored. By enforcing strict guidelines and providing a transparent process, GPC transactions ensure that government funds are used responsibly and that every transaction aligns with the agency's budgetary goals. The capacity for oversight over these transactions fosters a culture of financial responsibility and accountability within government agencies.
