Every federal agency has its own Office of Small & Disadvantaged Business Utilization Office (OSDBU or OSBU) that supports small businesses, proving information on contracting opportunities and other resources.
The Department of Labor’s OSDBU web page has a lot of great information to help you market to the agency, including OSDBU Key personnel and phone numbers, Agency credit card holders, IT representatives, Small business specialists, training representatives, the department’s procurement forecast, grant opportunities, and compliance assistance.
