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.
Support through free training, plain-language guides, and a team that is ready to help you before, during, and after the change.

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 the Town Hall recording to learn more about DIFS and the PASS Modernization project.
