Women-owned small businesses can compete for a specific pool of federal contracts that is legally set aside just for them. The program is called WOSB, Women-Owned Small Business, and it is a federal certification administered by the U.S. Small Business Administration. If you run a qualifying business in Missouri, here is what you need to know to get certified and start bidding.
What WOSB certification is
The WOSB Federal Contracting Program was created under the Small Business Act to help women-owned firms win more federal contracts. Congress mandated a 5% goal: at least 5% of all federal contracting dollars should go to women-owned small businesses each year. Certification is the mechanism that makes your business visible and eligible for those restricted competitions.
There are two tiers. A WOSB can compete for contracts in any of the 83 designated NAICS codes where women-owned firms are statistically underrepresented. An Economically Disadvantaged Women-Owned Small Business (EDWOSB) faces the same requirements but adds an income and asset cap, which opens a smaller subset of even more restricted competitions. You can hold both designations simultaneously.
Eligibility requirements
To qualify as a WOSB, your business must meet all of these conditions:
Ownership. At least 51% of the business must be unconditionally and directly owned by one or more women who are U.S. citizens. "Unconditional" means ownership cannot be subject to conditions that would transfer control away from women.
Control. Women must control the business, both in day-to-day operations and long-term strategic decisions. The woman owner (or owners) must hold the highest officer title and have the authority to make final decisions on contracts, personnel, and finances.
Size. The business must qualify as a small business under SBA size standards for its primary NAICS code. For most industries, the revenue cap sits at $30 million in annual receipts, though some manufacturing NAICS codes use employee-based size standards instead. You can check your specific NAICS code at sba.gov/size-standards.
For EDWOSB, there is an additional financial cap. Your adjusted gross income averaged over three years must be $400,000 or less (or $750,000 or less if you are primarily invested in your business), and your personal net worth must be below $750,000 excluding your primary residence and equity in the business.
How to apply
SBA replaced its old third-party certification requirement with a self-certification option in 2020, and then updated the rules again in 2023. As of January 1, 2024, self-certification alone is no longer sufficient for competing on WOSB set-aside contracts. You must obtain certification through an SBA-approved certifier.
Option 1: SBA direct certification. Apply through the SBA's free certification portal at certify.sba.gov. You create an account, complete the online application, upload supporting documents, and SBA reviews your submission. The SBA does not charge a fee. Processing times have historically run 60 to 90 days, though they vary with application volume.
Option 2: Third-party certifiers. SBA has approved four organizations to certify WOSBs:
- Women's Business Enterprise National Council (WBENC)
- National Women Business Owners Corporation (NWBOC)
- El Paso Hispanic Chamber of Commerce
- U.S. Women's Chamber of Commerce
Each has its own application process and fee structure. WBENC certification, for example, involves an in-person or virtual interview and site visit, and fees scale with annual revenue. The advantage is that WBENC certification is also recognized by many Fortune 500 supplier diversity programs, so one application can open both federal and corporate doors.
Regardless of which path you choose, your certification must appear in SAM.gov (the System for Award Management) before you can bid on set-aside contracts. SAM.gov registration is separate and free, but required.
What contracts it unlocks
WOSB and EDWOSB set-asides are available for contracts in 83 specific NAICS codes where SBA data shows women-owned firms are underrepresented. The list covers a broad range, including construction trades, professional and technical services, administrative support, healthcare, and IT.
Contracting officers can set aside a contract for WOSBs when the anticipated contract value falls between the micro-purchase threshold ($10,000) and the simplified acquisition threshold ($250,000). Above $250,000, officers can restrict competition to WOSBs or EDWOSBs if there is a reasonable expectation that at least two eligible firms will submit offers and the award will be made at a fair price.
Finding these opportunities requires regular searching in SAM.gov under set-aside type "WOSB" or "EDWOSB." You can also monitor agency forecast sites, which publish upcoming contract opportunities before they are formally solicited.
Federal buyers active in Missouri
Missouri has significant federal contracting activity. The state hosts several major military installations: Fort Leonard Wood (training and engineering), Whiteman Air Force Base (B-2 Spirit operations and maintenance), and Richards-Gebaur, which now operates as a joint use facility. Each generates procurement activity in logistics, construction, professional services, and support contracts.
Civilian agencies with Missouri footprints include the Department of Veterans Affairs (with medical centers in St. Louis and Kansas City), the Social Security Administration, the General Services Administration, and several Department of Agriculture offices. The VA in particular runs active small-business outreach programs and regularly awards contracts under WOSB set-asides.
Federal spending in Missouri runs into the billions annually across defense and civilian agencies. The contracts you can reach depend on your NAICS code and capabilities, not your geography, because federal contracts are competed nationally, but agencies often prefer contractors who can perform locally, especially for services and construction.
Free help from the APEX Accelerator in Missouri
Missouri PTAC at Missouri Enterprise is the state's APEX Accelerator, part of the national network of procurement technical assistance centers funded by the Department of Defense. Their counselors help businesses get registered in SAM.gov, find relevant contract opportunities, prepare bids, and navigate certifications including WOSB. The service is free.
Missouri Enterprise serves businesses statewide. To connect with an advisor, go to missourienterprise.org. Bringing your business financials, ownership documents, and operating history to the first meeting will save time.
Missouri state certifications that complement WOSB
Missouri does not have a state-level women-owned business certification that mirrors WOSB. However, the state does recognize certifications issued by outside bodies for public procurement.
For state contracting and utility supplier diversity programs, the relevant credentials are MBE (Minority Business Enterprise) and WBE (Women Business Enterprise) certification issued by the Missouri SDVOB program or accepted from NMSDC and WBENC affiliates. If you are also a minority-owned firm, the Mid-America Minority Business Development Council (Mid-America MBDC) is the NMSDC regional affiliate for Missouri and Kansas.
The Missouri Office of Equal Opportunity handles certification for state agency contracts under the Minority Business Enterprise program. If you do business with Missouri utilities such as Ameren or Kansas City Power & Light, those companies run their own supplier diversity programs and often accept WBENC or NMSDC certification directly.
DBE (Disadvantaged Business Enterprise) certification, administered by MoDOT, is required for federally funded transportation contracts. DBE certification overlaps in eligibility criteria with WOSB but is a separate process and serves a different contract pool.
Timeline and process steps
A realistic timeline for WOSB certification through SBA direct:
- Register in SAM.gov if you are not already. Allow two to four weeks for processing on a new registration.
- Gather documents: business formation documents, operating agreement or bylaws, three years of tax returns, proof of citizenship for woman owner(s), bank signature cards, and any licenses showing operational control.
- Submit through certify.sba.gov. The online application takes two to four hours depending on your document organization.
- SBA review: plan for 60 to 90 days.
- Once approved, confirm your WOSB designation appears in SAM.gov.
- Begin monitoring SAM.gov for WOSB and EDWOSB set-aside opportunities in your NAICS codes.
Total elapsed time from starting SAM.gov registration to first bid eligibility: four to five months if you move steadily. Missouri Enterprise PTAC can help compress that timeline by flagging common application errors before you submit.
