Which of the following positions is responsible for approving the purchase card invoice?

The Certifying Official is responsible for approving the purchase card invoice because this role carries the authority to validate and confirm that the transactions are appropriate, necessary, and comply with the organization's policies and regulations. The Certifying Official ensures that the funds are available and that the purchase aligns with the established guidelines before approval, which is crucial for maintaining financial integrity and accountability within the organization.

In contrast, while the Cardholder makes purchases and potentially initiates the invoice, they do not have the authority to approve payments. The Approving Official may oversee the process but is typically not the one who certifies invoices for payment. The Program Coordinator may have an administrative function regarding purchase cards but does not hold the responsibility for invoice certification. Therefore, the role of the Certifying Official is vital in the financial process to ensure all transactions are legitimate and properly documented.
