The U.S. Department of Transportation (DOT) has fully implemented its new department-wide electronic grant payment system, Delphi eInvoicing System. The system provides a web-based standardized portal for grantees to electronically request grant payments and monitor payment status. All airport sponsors have transitioned to this new system.

Delphi eInvoicing eAuthentication
The Office of Management and Budget (OMB) and the DOT require that the identity of Delphi eInvoicing users be authenticated and verified. This eAuthentication process contains two major sets of requirements that must be met:
- The verification of the user prior to the issuance of the credentials (identity proofing)
- A technical authentication method (username and password)
Prior to accessing the eInvoicing system, all grant sponsors must complete the eAuthentication certification process.
