WOSB vs EDWOSB: what's the difference?

Both WOSB and EDWOSB are statuses within SBA's Women-Owned Small Business Federal Contract program. EDWOSB is a narrower status with economic limits on the owners, and it qualifies a firm for an extra pool of set-asides that ordinary WOSBs cannot bid on. Because the two labels look so similar on SAM.gov notices, many women business owners are unsure which they hold, which they could hold, and what difference it makes. This guide compares them in detail using SBA's own rules, explains which contracts each can pursue, walks through certification, and covers what it takes to stay certified.

The program in brief

The government limits competition for certain contracts to businesses in the WOSB program, and it aims to award at least 5% of federal prime contracting dollars to women-owned small businesses each year, according to SBA's WOSB Federal Contract program page. The contracts covered are for goods and services in specific industries, identified by NAICS code, where SBA has determined women-owned small businesses are underrepresented. Some of those contracts are restricted further to EDWOSBs. The full rules are in Title 13, Part 127 of the Code of Federal Regulations.

WOSB eligibility

To be eligible as a WOSB, a business must be small under SBA size standards for its industry, must be at least 51% owned and controlled by women who are U.S. citizens, and must have women managing day-to-day operations who also make long-term decisions. Each part of that test matters. Ownership is about who holds the equity. Control is about who actually runs the company, which SBA looks at closely: a firm where a woman holds 51% of the shares but a male co-owner makes the major decisions may not meet the control requirement. Size is measured against the SBA size standard for the relevant NAICS code.

EDWOSB eligibility

An EDWOSB must meet every WOSB requirement, and its women owners must also be economically disadvantaged. SBA defines that with three tests that each owner relied on must meet: a personal net worth of less than $850,000, adjusted gross income of $400,000 or less averaged over the previous three years, and $6.5 million or less in personal assets. Funds invested in an official retirement account are excluded when SBA calculates personal net worth. SBA has aligned these economic disadvantage standards with the 8(a) Business Development program, and 8(a) firms pursuing EDWOSB certification may submit their most recent 8(a) annual review letter, or acceptance letter if in their first year, when they apply.

Which contracts can each bid on?

WOSB and EDWOSB set-asides apply only in NAICS codes that SBA has designated as eligible, and SBA publishes the list on its WOSB program page. A certified EDWOSB can compete for both WOSB and EDWOSB set-asides. A WOSB that is not also an EDWOSB can compete for WOSB set-asides but not for those reserved for EDWOSBs. Either can also compete in total small business set-asides and full and open competitions, and, if eligible, in other socioeconomic programs such as 8(a) and HUBZone; FAR 19.203 gives none of the four programs precedence over the others.

A hypothetical example makes the industry rule concrete. A woman-owned engineering firm that also sells commercial furniture might find that its engineering NAICS code is on SBA's eligible list while its furniture code is not. It could use WOSB status for engineering set-asides but would compete for furniture contracts through ordinary small business set-asides instead. Before applying, check your main codes against SBA's list so you know where the certification will actually help.

On SAM.gov and on SetAside Signal you will see these notices labeled by their FAR authority, for example on our page of current WOSB set-aside opportunities. Some notices are sole-source awards, where the agency intends to award to a specific certified firm without competition.

How to get certified

Self-certification for WOSB set-asides ended in 2020, when SBA implemented changes Congress made in the 2015 National Defense Authorization Act. Today, every firm must apply through SBA Certifications, SBA's free online system, before competing for WOSB program set-asides. Alternatively, a firm can be certified by one of the four SBA-approved third-party certifiers, which SBA lists as the El Paso Hispanic Chamber of Commerce, the National Women Business Owners Corporation, the U.S. Women's Chamber of Commerce and the Women's Business Enterprise National Council. Third-party certifiers may charge fees, and a firm certified that way must still upload its certificate and proof of citizenship to SBA Certifications before bidding.

Whenever practicable, SBA makes its decision within 90 calendar days after receiving a complete application. If the application is incomplete, an SBA representative may request more information, which pauses progress, so it pays to assemble documents carefully at the start. Typical materials include ownership documents, governing documents such as operating agreements or bylaws, and, for EDWOSB, personal financial information for the owners. Your business must also have an active SAM.gov registration.

Staying certified

Certification is not permanent without upkeep. SBA requires certified firms to undergo a program examination every three years, conducted by SBA or a third-party certifier. SBA's rules also call for an annual attestation, which SBA notes is currently in abeyance, so firms do not have to submit it at this time; check the program page for changes. Firms must update their SAM.gov registration annually so their Small Business Search profile stays active. If ownership, control or finances change, for example if a new investor buys in or an owner's net worth rises above the EDWOSB limit, eligibility may change too.

Choosing between them

For most firms the choice makes itself: if your women owners meet the economic tests, apply as an EDWOSB, since that status covers both pools of set-asides. If they do not, apply as a WOSB. Either way, the certification is only as valuable as the contracts in your industry, so look at how often agencies actually issue WOSB and EDWOSB set-asides in your NAICS codes before investing the time. Our post comparing HUBZone, WOSB, SDVOSB and 8(a) set-asides can help if you might qualify for more than one program.

Frequently asked questions

What is the difference between WOSB and EDWOSB?

EDWOSB firms meet all WOSB requirements and their women owners are also economically disadvantaged (personal net worth under $850,000, average AGI of $400,000 or less, and $6.5 million or less in assets). EDWOSBs can bid on both WOSB and EDWOSB set-asides.

Can I self-certify as a WOSB?

No. Since 2020, firms must be certified through SBA Certifications (or an SBA-approved third-party certifier, with documents uploaded to SBA) to compete for WOSB set-asides.

Is WOSB certification free?

Certifying through SBA is free. Third-party certifiers may charge fees.
