Delphi eInvoicing System Deployment Schedule

The Department of Transportation (DOT) has implemented a program to transform and automate the grants payment process. This program will improve online invoice processing activities by having grant recipients submit invoices electronically via a new system called 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.
