What does Invoice Submission in DIFS mean for Suppliers?

Suppliers will submit invoices, track status, and view payments information through a single portal.
Real-time visibility into your invoices and payments, without making calls or sending emails to check on status.
Plain-language guides and the DIFS Help Desk is ready to help you before, during, and after the change:
- (202) 671-3437 (Monday through Friday, 7:00 am to 5:30 pm)
- [email protected]
- Zendesk Ticket

What will stay the same?

How you bid. Registration for PASS Sourcing events and the way you find and respond to solicitation opportunities remain the same.
Your payment terms. How or when you get paid will not change.
Your standing. Your contracts, your certifications, and your history with the District are carried forward.

In case you missed it, check out these presentations to learn more about the DIFS Supplier Portal and how to submit an invoice.
