What WOSB certification is
Women-Owned Small Business (WOSB) certification is a federal designation that lets the government set aside contracts exclusively for women-owned firms. It sits inside the SBA's procurement preference programs alongside 8(a), HUBZone, and SDVOSB. Contracting officers can use WOSB set-asides on contracts valued between $10,000 and $7 million (or $4 million for manufacturing) without competitive bidding across the full market.
The program targets 83 NAICS industry codes where the SBA has determined women-owned firms are underrepresented in federal contracting. That list spans construction, professional services, IT, healthcare support, and dozens of others. If your primary NAICS code falls on that list, set-asides are available to you. If not, you can still pursue contracts under the Economically Disadvantaged WOSB (EDWOSB) designation, which adds an additional income threshold but opens competition in another set of NAICS codes.
Eligibility requirements
The baseline requirements are not complicated, but you have to meet all of them:
Ownership. At least 51% of the business must be owned by one or more women who are U.S. citizens. This means equity ownership, not just operational control.
Control. Women must control both the day-to-day management and the long-term strategic decisions of the business. If a male spouse or business partner holds majority voting rights or has veto power over major decisions, that is a problem during certification review.
Size standard. The business must qualify as small under the SBA size standard for its primary NAICS code. For most service industries, WOSB uses the revenue-based size standard, which caps at $30 million for a large number of codes. Manufacturing industries use employee-count standards instead. You can look up the exact threshold for your NAICS code at SBA's table of size standards.
EDWOSB additional threshold. If you want the Economically Disadvantaged designation, personal net worth of each woman owner must be below $850,000 (excluding equity in the business and primary residence), adjusted gross income must average below $400,000 over the prior three years, and total personal assets must be below $6.5 million.
How to apply
You have two routes: SBA self-certification or certification through an SBA-approved third-party certifier.
SBA self-certification at certify.sba.gov. Create an account, complete the online questionnaire, and upload supporting documents. Required documents typically include articles of incorporation or organization, operating agreement or bylaws, stock certificates or membership certificates showing ownership percentages, and a personal financial statement if applying for EDWOSB. The SBA does not conduct an in-person site visit for self-certification, but the agency may audit your file at any time, and contracting officers can challenge certifications. Self-certification is free and does not expire, though you must recertify annually to confirm continued eligibility.
Third-party certification. Four organizations are currently approved by the SBA to issue third-party WOSB certifications:
- WBENC (Women's Business Enterprise National Council)
- NWBOC (National Women Business Owners Corporation)
- El Paso Hispanic Chamber of Commerce
- U.S. Women's Chamber of Commerce
Third-party certification requires an on-site or virtual review and carries a fee that varies by certifier and business size. WBENC's fee ranges from roughly $350 to $1,250 per year depending on annual revenue. The review process is more rigorous, which makes the resulting certification more defensible if a contracting officer or competitor challenges it.
For most Tennessee businesses just getting started, SBA self-certification is the faster and cheaper path. If you plan to pursue large contracts where challenges are more likely, third-party certification is worth the cost.
What contracts it unlocks in Tennessee
Tennessee has substantial federal buying activity across multiple agencies. The Department of Defense is the largest federal buyer in the state, driven by installations including Arnold Air Force Base in Tullahoma, Naval Support Activity Mid-South in Millington, and Fort Campbell on the Kentucky border. These installations contract for construction, facilities management, logistics support, professional services, and IT.
The Tennessee Valley Authority, headquartered in Knoxville, is a federal corporation and one of the largest public utilities in the country. TVA has active supplier diversity outreach and awards contracts in engineering, environmental services, construction, and operations support.
The Department of Veterans Affairs operates multiple medical centers in Tennessee, including facilities in Memphis, Nashville, Mountain Home, and Murfreesboro. VA medical centers are active buyers of healthcare support services, facilities management, IT, and administrative services. Many of these NAICS codes fall within WOSB-eligible industries.
NASA's Marshall Space Flight Center is in Huntsville, Alabama, just across the state line, and regularly works with Tennessee-based suppliers on engineering and technical support contracts.
To find active opportunities, search SAM.gov using your NAICS code with the "Set-Aside" filter set to WOSB or EDWOSB. You can also register in SAM.gov as a WOSB and get notified of relevant solicitations.
Tennessee state-level certifications that complement WOSB
WOSB is federal only. Tennessee has its own certification programs that operate separately and serve different buyers.
The Tennessee Department of Transportation (TDOT) administers the Disadvantaged Business Enterprise (DBE) program, which is required for federally funded transportation projects. DBE certification is based on social and economic disadvantage, not gender alone, though many women-owned firms qualify. DBE opens bidding opportunities on highway construction, bridge work, transit projects, and airport infrastructure funded by federal transportation dollars.
The state also operates the Small and Minority Business program under the Department of General Services. This certifies women-owned businesses for state government procurement preferences on Tennessee contracts. It is separate from WOSB and applies to state agency buying, not federal.
If you sell to both federal agencies and state/local government buyers, or to prime contractors working on state transportation projects, pursuing both WOSB and Tennessee DBE certification is worth the effort. The document requirements overlap significantly: you will gather most of what you need for one application while completing the other.
Getting help from the Tennessee APEX Accelerator
The Tennessee APEX Accelerator (formerly Procurement Technical Assistance Center) provides free one-on-one advising to businesses pursuing federal and state government contracts. Advisors can walk you through the certification application, review your documents before submission, help you register in SAM.gov, and identify contract opportunities that match your capabilities.
This is not a paid consulting service. It is federally funded assistance available to Tennessee businesses at no cost. If you are starting from scratch on WOSB or any other certification, a session with a Tennessee APEX Accelerator advisor is the right first call. You can find the program through the APEX Accelerator locator at apexaccelerators.us.
Timeline and process steps
Here is a realistic sequence for getting certified and competing for your first WOSB set-aside:
- Confirm NAICS eligibility. Look up your primary NAICS code against the SBA's WOSB-eligible industry list. Confirm you meet the size standard for that code.
- Register in SAM.gov. Federal contracting requires an active SAM.gov registration. This takes 7 to 10 business days and must be renewed annually. WOSB certification is not valid for federal contracting without an active SAM registration.
- Gather documents. Collect your ownership documents, operating agreement or bylaws, bank signature authority records, and a resume demonstrating management experience. For EDWOSB, add personal financial statements.
- Apply at certify.sba.gov. The online application takes 2 to 4 hours if your documents are organized. SBA typically processes applications within a few weeks.
- Apply for Tennessee DBE if applicable. If you pursue transportation or state government work, start the TDOT DBE application after your WOSB is approved. Many documents carry over.
- Search SAM.gov for opportunities. Filter for WOSB and EDWOSB set-asides in your NAICS codes. Set up email alerts for new postings.
The full cycle from document gathering to receiving your first contract bid takes most businesses three to six months. Certification itself can be completed in under 30 days if your documentation is clean.
