Which document must be included for all GPC transactions?

A detailed receipt is crucial for all Government Purchase Card (GPC) transactions because it serves as the primary documentation to validate the purchase. The receipt provides important information such as the date of the transaction, the items or services purchased, the amount spent, and the vendor details. This documentation is necessary for ensuring compliance with procurement regulations, providing a clear audit trail, and assisting in budget management.

In the context of GPC usage, the detailed receipt is essential for substantiating expenditures and demonstrating that the items acquired were actually received and are in line with authorized purchases. Without this documentation, it becomes challenging to justify the legitimacy of the transaction during audits or reviews.

Other documents like purchase orders, email confirmations, and signed contracts may apply in specific circumstances but are not universally required for every GPC transaction. Each of these documents may provide useful information or context for specific purchases but do not replace the need for a detailed receipt, which is the foundational proof of the transaction.
