Can I hold WOSB and 8(a) certification at the same time?

Yes. WOSB and 8(a) certifications are fully compatible. Many women-owned businesses hold both, allowing them to compete for both WOSB set-asides and 8(a) set-asides/sole-source contracts. Other compatible certifications include HUBZone, SDVOSB (for veteran women business owners), and state-level WBE and DBE certifications.

What Is WOSB Certification?

The Women-Owned Small Business (WOSB) Federal Contracting Program is an SBA initiative that helps women-owned businesses compete for federal contracts in industries where women are historically underrepresented. When a contracting officer determines that two or more WOSB firms are likely to compete, they can set aside the contract exclusively for WOSB or EDWOSB firms.

WOSB set-asides cover over 600 NAICS codes across industries including professional services, construction, healthcare, technology, and more. The federal government awards over $25 billion annually to WOSB-certified businesses.

EDWOSB (Economically Disadvantaged WOSB) is a subset of the WOSB program with additional financial eligibility requirements. EDWOSB firms qualify for both WOSB-designated set-asides and EDWOSB-designated set-asides, giving them access to a broader range of opportunities.

Who Qualifies for WOSB Certification?

To qualify for WOSB certification, your business must meet all of the following:

Ownership: The business must be at least 51% unconditionally and directly owned by one or more U.S. citizens who are women.
Control: Women must control the long-term decision-making and daily management of the business. The highest officer position (CEO, President, or equivalent) must be held by a woman owner.
Size: The business must qualify as small under SBA size standards for its primary NAICS code.
Industry eligibility: The business must operate primarily in a NAICS code designated as underrepresented or substantially underrepresented for WOSB set-asides.

For EDWOSB, additional requirements apply to each woman owner with 51%+ ownership:

Personal net worth below $850,000 (excluding equity in the business and primary residence)
Adjusted gross income of $450,000 or less on average over the past 3 years
Total assets of $6.5 million or below

Benefits of WOSB Certification

Set-aside access in 600+ NAICS codes: Contracting officers can set aside contracts exclusively for WOSB firms, dramatically reducing your competition to other women-owned businesses.
Sole-source contracts for EDWOSB: EDWOSB firms can receive sole-source contracts up to $4.5M for services and $7M for manufacturing in certain circumstances, without competition.
Subcontracting goals: Large prime contractors are required to set subcontracting goals for women-owned businesses. WOSB certification makes you visible to large contractors actively seeking certified subcontractors.
Compatible with other certifications: WOSB/EDWOSB can be held alongside 8(a), HUBZone, SDVOSB, and state-level WBE and DBE certifications.
Self-certification available: Unlike some programs, WOSB allows self-certification through SBA Certify, making initial certification faster and lower-cost than programs requiring third-party review.

WOSB vs. EDWOSB: Which Should You Apply For?

If you meet the EDWOSB financial eligibility requirements (personal net worth below $850K, AGI below $450K, total assets below $6.5M), apply for EDWOSB, it provides access to both WOSB and EDWOSB set-asides. If you don't meet the EDWOSB financial thresholds, apply for WOSB, which still provides access to the broader set of WOSB-designated opportunities.

GovLadder's free eligibility check evaluates both WOSB and EDWOSB requirements and recommends which designation to pursue.

How Much Revenue Can WOSB Generate?

The federal government awarded over $25 billion to WOSB-certified businesses in recent fiscal years. Set-aside access in 600+ NAICS codes means WOSB is relevant across nearly every industry, from IT services and healthcare to construction and professional consulting.

How to Get WOSB Certification

Verify your business qualifies as small

Check your primary NAICS code against SBA size standards at sba.gov. WOSB applies only to businesses meeting the SBA small business definition. Size is measured by revenue or employee count depending on your industry.

Gather ownership documentation

Prepare: operating agreement or corporate bylaws showing women's 51%+ ownership, stock certificates, buy-sell agreements, business bank account statements, and any other documents demonstrating women's unconditional ownership and day-to-day control.

Verify SAM.gov registration is active

Log into sam.gov and confirm your entity registration is current. Your primary NAICS code in SAM.gov should reflect your main business activity, this affects which set-aside opportunities you're eligible for.

Apply through SBA Certify

Go to certify.sba.gov and start a WOSB or EDWOSB application. Upload your ownership documents, personal financial statements (for EDWOSB), and any additional documentation the system requires. SBA review typically takes 30–45 days from a complete submission.

Consider third-party certification for maximum credibility

While self-certification is accepted, some contracting officers and prime contractors prefer or require third-party WOSB verification. Approved certifiers include NWBOC, WBENC, USPAACC, and El Paso Hispanic Chamber of Commerce. Third-party certification takes 4–8 weeks and may include site visits.

Common Mistakes That Delay WOSB Applications

Mistake 1

Incomplete ownership documentation. The SBA requires clear evidence that women own 51%+ of the business unconditionally. Missing a buy-sell agreement, outdated operating agreement, or missing stock certificates are the most common causes of WOSB application delays.

Mistake 2

Applying in the wrong NAICS code. WOSB set-asides are only available in specific NAICS codes where women are underrepresented. If your primary NAICS code is not on the WOSB-eligible list, you won't be able to pursue WOSB set-asides in your primary industry. GovLadder verifies this during the eligibility check.

Mistake 3

Women don't control daily management. If a man manages daily operations while women hold ownership shares passively, the business doesn't meet the WOSB control requirement. The highest officer must be a woman owner actively managing the business.
