Direct UNC to strengthen its administrative and management processes and procedures surrounding the approval of vendor and service provider invoices. Updated procedures could include: a. Updating UNC’s invoice approval process to require that the approver verify that costs invoiced by the vendor or service provider are consistent with the costs outlined in the vendor/service agreement. b. Requiring organizations that invoice UNC for conference travel expenses to provide original receipts that support the allowability of the travel expenses and/or justifications to support how the organization established the travel stipend award amounts.
