WOSB Certification for Professional Services Companies

Federal certification for businesses at least 51% owned and controlled by women.

Professional services is the fastest path to contracting for many diverse businesses. Here's why certification matters:

Low Barriers to Entry: Unlike manufacturing or construction, professional services require expertise rather than equipment or facilities.

High Demand: Every organization needs professional services - consulting, staffing, legal, accounting, marketing.

GSA Schedule Access: Professional services are well-suited for GSA Schedule contracts, opening federal opportunities.

Corporate Spending: Fortune 500 companies spend billions annually on professional services with supplier diversity goals.

Subcontracting Opportunities: Large consulting firms (Big 4, Accenture, etc.) actively seek diverse subcontractors.

Professional services certifications can unlock opportunities in virtually every industry vertical.

51% owned by women citizens, women control management and daily operations, meets SBA size standards.

What counts as a women-owned small business In federal law, a women-owned small business (WOSB) is a firm that is small under the size standard for a NAICS code in its SAM profile and is not less than 51% unconditionally and directly owned and controlled by one or more women who are U.S. citizens and live in the United States (13 CFR 127.200, read on eCFR November 3, 2026). SBA certification is required only to win WOSB or EDWOSB set-aside and sole-source contracts. A women-owned small business that does not pursue those contracts may self-certify, win awards outside the program, and still count toward an agency's women-owned small business goal, which SBA lists as 5% of federal contracting dollars (13 CFR 127.200(c)(2); SBA contracting goals, checked November 3, 2026). WBENC's WBE is a separate, private standard used by corporate buyers. This guide covers who qualifies and what the program opens; the document list lives in our WOSB certification requirements checklist.

WOSB eligibility is defined in 13 C.F.R. Part 127. There are two tiers: WOSB (basic) and EDWOSB (economically disadvantaged). Both require the same ownership and control criteria; EDWOSB adds a net worth and income test.

Ownership

• 51% unconditionally and directly owned by one or more women who are U.S. citizens and live in the United States
• Ownership must be genuine, not a gift or nominal transfer designed solely to qualify
• For publicly traded companies: women must own at least 51% of each class of voting stock

Control: management

• A woman must hold the highest officer position in the business (CEO, President, Managing Member, or equivalent)
• A woman must manage the business on a full-time basis during normal business hours
• Women must make long-term strategic decisions for the business

Control: daily operations

• Women must control day-to-day management and administration
• A woman must have the technical expertise to manage the firm's primary industry, or hold ultimate decision-making authority over those who do
• The highest officer position cannot be held by a man, even temporarily

Business requirements

• Must be a small business under SBA size standards for the applicable NAICS code (verify at sba.gov/size-standards)
• Must be a for-profit business operating in the United States
• SBA publishes a list of NAICS codes where WOSBs are underrepresented or substantially underrepresented; WOSB set-asides are restricted to those codes

EDWOSB additional requirements (applied simultaneously)

• Personal net worth below $850,000 (excludes equity in primary residence and in the EDWOSB firm)
• Three-year average adjusted gross income below $400,000
• Total personal assets below $6.5 million
• These thresholds mirror the 8(a) economic disadvantage standard

Step 1: Confirm SAM.gov registration is active WOSB certification requires an active SAM.gov registration. Log into sam.gov, verify your registration is current, and confirm your legal business name and address match exactly what will appear on the SBA application. SAM.gov renewals take 7-10 business days; do not wait until the last minute.

Step 2: Determine whether you qualify for EDWOSB simultaneously Run the economic disadvantage numbers before you open the certifications.sba.gov application. Calculate your personal net worth: add all personal assets (brokerage accounts, real estate other than your primary residence, retirement accounts, vehicles, ownership interests in other businesses), subtract personal liabilities, and exclude equity in your primary home and your ownership stake in the applying firm. If the result is below $850,000 and your 3-year average adjusted gross income is below $400,000, you qualify for EDWOSB. Apply for EDWOSB at the same time; it uses the same application with additional financial disclosures.

Step 3: Gather documents before opening the application The certifications.sba.gov portal session times out. Have every document scanned and labeled before you start: citizenship proof, operating agreement or bylaws, stock certificates or membership ledger, 2-3 years of business tax returns, personal financial statement (for EDWOSB), SAM.gov registration confirmation, and a current business license.

Step 4: Apply at certifications.sba.gov Create or log into your SBA certifications.sba.gov account and select the WOSB (and EDWOSB if applicable) program. The application covers ownership structure, control documentation, business details, and financial information. Be precise and consistent; reviewers cross-check your application answers against your supporting documents.

Step 5: Respond to SBA requests promptly After submission, SBA may issue a request for additional information (RFAI). You have 15 days to respond. Missing this deadline pauses or closes your application. Check the portal weekly and monitor the email address on your SBA account.

Step 6: Certification decision SBA targets 90 days from a complete application for review and decision. Complex ownership structures may take longer. Once certified, your WOSB/EDWOSB status is reflected in your SAM.gov record and visible in the Dynamic Small Business Search (DSBS), which contracting officers use to find WOSB firms.

Step 7: Set up for contract pursuit After certification, search for WOSB and EDWOSB set-aside opportunities on sam.gov using the "type of set-aside" filter. Review the SBA's current list of NAICS codes where WOSBs are underrepresented (published on sba.gov) to understand which industries your set-aside eligibility covers. Update your SAM.gov profile with your WOSB certification and capability description.
