What must accompany any service purchase made with GPC?

When making a service purchase with a Government Purchase Card (GPC), it is essential to accompany the transaction with a written statement justifying the necessity for the service. This justification serves multiple critical purposes: it helps ensure that the expenditure is appropriate, aligns with government regulations and policies, and provides transparency and accountability regarding the use of government funds. The written statement helps to document the need for the services, making it easier to provide oversight and manage budgets effectively.

Additionally, this form of documentation is essential for compliance with federal procurement regulations, which mandate that federal agencies must justify their purchases to prevent wasteful spending and ensure that government resources are used efficiently. The inclusion of this justification not only protects the integrity of the purchasing process but also serves to safeguard officials from potential audit issues and misuse of funds.

The other options do not fulfill the requirements set forth for service purchases made with a GPC. A purchase order may be common in traditional procurement processes but is not typically required for GPC purchases. A verbal agreement from the vendor lacks the necessary documentation and formalization needed in government procurement. Lastly, operating without documentation goes against the principles that govern GPC transactions, as all expenditures must have clear, written justification to promote accountability.
