Welcome to the District Integrated Financial System, DIFS!

♦ ♦ Important Announcement for Procurement Suppliers ♦ ♦ 

The DIFS Supplier Portal has replaced the DC Vendor Portal starting on November 2, 2026.

DIFS will deliver “one-stop shop” self-service functionality and enable you to:

• Submit invoices and track payments,
• Upload supporting documentation, and
• Update your profile (address, contacts, and bank information).

Key details for the November 2 go-live:

• November 2, 2026: DIFS goes live for Procurement Supplier registration and self-service profile management.  Invoices approved by the agencies in PASS prior to November 20 will be automatically migrated to DIFS. Invoices rejected in PASS after October 30 will need to be re-entered by the Supplier in the DIFS Supplier Portal. Any invoices not approved in PASS by November 20 will be processed manually by the OCFO
• September 30, 2027: Last day to access historical invoices in the DC Vendor Portal.
