How to register, step by step
- Gather your information. Have these ready: Register in the DIFS Supplier Portal to receive payment from the District; Multi-factor authentication; Several forms including a W-9 (new suppliers).
- Register in DIFS Supplier Portal (District Integrated Financial System, run by OCFO). Start at cfo.dc.gov. Use your exact legal name and taxpayer ID so your record matches tax and payment systems.
- Describe what you sell. If the system asks for commodity or service codes, choose them carefully: agencies and bid notices often use them to find vendors.
- Keep your profile current. Update contacts, codes and documents so notices and purchase orders reach the right people.
- Look beyond the state. Cities, counties, school districts, universities and utilities in the District of Columbia often run their own vendor registration and bid systems.
Good to know
The DIFS Supplier Portal replaces the DC Vendor Portal effective November 2, 2026 for registration, profile management and invoicing.
After you register
Registration is the entry ticket, not the sale. Most District purchases above small-dollar thresholds go through competitive bids or existing contracts, including cooperative contracts many agencies use. Watch the District's bid notices, learn which contracts agencies buy from, and start conversations with the program staff who own the problems you solve before a solicitation is written. Our guides to government buying signals and cooperative purchasing explain how.
