WOSB stands for women owned small business, which simply requires that a small business be at least 51 percent owned and operated by women who are U.S. citizens. EDWOSB stands for economically disadvantaged women owned small business, which must meet the requirements for WOSBs, and also prove the owner comes from an economically disadvantaged background. This includes having a low personal net worth and other qualifications. EDWOSB certification may open a business up to even more government contracting opportunities, though both provide benefits. Whether you’re considering WOSB or EDWOSB certification, you’ll need to submit information about company ownership and management to the SBA or third party certification providers.
