How does the GPC differ from a traditional purchase order?

The correct choice reflects the primary benefit of the Governmentwide Commercial Purchase Card (GPC) compared to traditional purchase orders. The GPC is designed to streamline the procurement process, allowing for faster and more efficient purchasing of goods and services. This is achieved by reducing the amount of required documentation, which typically leads to expedited purchases.

In contrast, traditional purchase orders often involve more extensive paperwork and approvals that can slow down the acquisition process. This speed and efficiency make the GPC a valuable tool for small purchases where quick access to funds is necessary, supporting operational agility.

The other options do not accurately represent the characteristics of the GPC. While it does have spending limits, they are not strictly without exceptions. Additionally, the GPC is not exclusively for travel-related expenses; it can be used for a wide range of purchases. Lastly, the GPC process is intended to be more streamlined rather than involving more approvals and a longer process.
