Delphi eInvoicing System

What is eInvoicing?

eInvoice has been implemented by the Department of Transportation (DOT) as a program to transform and automate the invoice and grants payment process. This program will improve online invoice processing activities by having vendor and grant recipients submit invoices electronically via the Delphi eInvoicing System.

The Delphi eInvoicing System is a real-time invoicing tool that improves efficiency and data transparency by reducing the time between invoice submission and payment and by providing grant recipients with accurate invoice status reporting capabilities.

The system will be available for invoice submission and processing from 6:00am ET Monday through 9:00pm ET Saturday. System maintenance will occur between 9:00pm ET Saturday through 6:00am ET Monday.
