Women-Owned Small Business (WOSB)

A Women-Owned Small Business (WOSB) is a small business that is at least 51% owned by one or more women, where those women also control daily operations and long-term management decisions. WOSB status is recognized under federal small business programs to promote participation by women entrepreneurs in government contracting.

What Is a Women-Owned Small Business?

A Women-Owned Small Business (WOSB) is a small business that is at least 51% owned by one or more women, where those women also control daily operations and long-term management decisions.

WOSB status is recognized under federal small business programs to promote participation by women entrepreneurs in government contracting.

Key Characteristics

At least 51% direct and unconditional ownership by one or more women

Women owners must control day-to-day operations and long-term strategic decisions

Must meet SBA size standards for the applicable NAICS industry classification

Eligible for federal set-aside contracts in underrepresented industries

Subject to SBA certification requirements and ongoing compliance obligations

How It Works in Government Contracting

Where It Appears in the Procurement Lifecycle: WOSB status is used during acquisition planning when agencies designate set-aside contracts, during source selection when evaluating small business eligibility, and in subcontracting plan compliance for large prime contractors required to allocate spending to small business categories.

Who Uses It: Federal contracting officers use WOSB designations to structure set-aside opportunities, while women-owned businesses use certification to access reserved competitions. Large prime contractors also seek WOSB partners to fulfill subcontracting plan requirements.

Why It Matters: The federal government maintains a goal of awarding at least 5% of federal contracting dollars annually to WOSBs. Certain contracts are set aside exclusively for WOSBs or Economically Disadvantaged WOSBs (EDWOSBs) in industries where women are underrepresented, creating targeted competitive opportunities for qualifying firms.

Practical Application

Example 1 — Set-Aside Award: A women-owned IT consulting firm competes for a WOSB set-aside contract reserved for industries where women are underrepresented, winning a federal task order without competing against larger firms.

Example 2 — EDWOSB Eligibility: A small engineering firm owned by a woman meeting additional financial disadvantage criteria qualifies as an EDWOSB and accesses a narrower pool of reserved contract opportunities.

Example 3 — Subcontracting Partnership: A large defense prime contractor identifies a WOSB-certified firm as a subcontractor to meet its small business subcontracting plan goals under a major DoD contract.

Regulatory Framework

WOSB participation is governed by federal small business law and acquisition regulations that establish eligibility requirements, certification procedures, and contracting rules:

The Small Business Act, 15 U.S.C. § 637(m)

Federal Acquisition Regulation (FAR) Part 19

SBA Women-Owned Small Business Program regulations

Why It Matters for Contractors

Business Implications: WOSB certification provides access to set-aside contracts, increased visibility in federal databases, greater competitiveness in subcontracting, and enhanced credibility in diversity and inclusion programs pursued by both government agencies and large prime contractors.

Compliance Impact: WOSBs must maintain the required ownership structure, ensure women retain operational control, keep certification documentation current, and report any changes in ownership or management. Failure to maintain eligibility can result in loss of WOSB status.

Strategic Importance: Many prime contractors actively seek WOSB partners to meet subcontracting goals, creating teaming and partnership opportunities beyond direct set-aside awards. WOSB certification can open doors to both prime and subcontracting revenue streams.

Risk Considerations: Key risks include failure to maintain required ownership or control structures, lapses in certification documentation, unreported changes in management, and competing in set-aside categories without maintaining eligibility — all of which can result in loss of status or contract termination.

Common Misconceptions About WOSB

Any business owned by a woman automatically qualifies.

The business must meet strict ownership, control, and size standards — simple majority ownership alone is not sufficient.

Certification guarantees contracts.

WOSBs must still compete and meet all proposal requirements; certification provides access to set-asides, not automatic awards.

A woman can be listed as majority owner without operational control.

Control and management authority over daily operations and long-term decisions are mandatory requirements for WOSB qualification.

Frequently Asked Questions

How is WOSB certification obtained?

Through the SBA's certification process or an SBA-approved third-party certifier.

What is an EDWOSB?

An Economically Disadvantaged Women-Owned Small Business that meets additional financial eligibility requirements beyond standard WOSB criteria.

Can a WOSB compete for non-set-aside contracts?

Yes. WOSBs can compete in full and open competitions in addition to set-aside opportunities.

Does WOSB status apply to all industries?

Yes, but certain industries have specific WOSB or EDWOSB set-aside eligibility based on underrepresentation data.
