The federal government sets aside certain contract bid opportunities exclusively for small businesses.
In order to compete for these contracts, you must first register as a vendor with the government. As part of the registration process, you will be required to enter information about your company in the System for Award Management (SAM) database where you may self-certify as a small business.
The federal government also has programs that help small businesses owned, operated and actively managed by women, minority group members, veterans or persons with disabilities compete in the marketplace.
You can find federal government contract certifications here that include Small Disadvantaged Business (SDB) 8(a) program, HUBZone Empowerment Contracting and Certification, Woman-Owned Business Certification, Veteran-Owned Small Business, and Service Disabled Veteran Owned Small Business.
