Our Verified Certifications

Every certification listed below is current, verifiable, and documented. Procurement officers and vendor qualification teams can verify each credential directly through the issuing organization.

Cert · 01

Women's Business Enterprise National Council (WBENC) Certification

Certification HolderMarcie Manfredonia-Siciliano, President & CEO

Verify at WBENC.org

What It Is

WBENC certification is the most widely recognized and rigorous Women's Business Enterprise certification in the United States. Issued by the Women's Business Enterprise National Council, WBENC certification requires a comprehensive review of business ownership, control, and management to confirm that the business is at least 51% owned, controlled, and operated by one or more women. The review includes documentation review, site visits, and periodic recertification — making WBENC the gold standard for WBE verification accepted by Fortune 500 companies, federal agencies, and state and local governments.

What It Means for Your Procurement

WBENC certification is accepted by more than 10,000 corporations and government entities as proof of women's business enterprise status for supplier diversity programs. For Fortune 500 companies with supplier diversity spending requirements and government agencies with WBE procurement set-asides, Nationwide Maintenance's WBENC certification satisfies vendor qualification requirements directly — no additional verification needed.

Cert · 02

SBA Women-Owned Small Business (WOSB) Federal Contract Program

Certification HolderMarcie Manfredonia-Siciliano, President & CEO

Verify at SBA.gov

What It Is

The SBA Women-Owned Small Business (WOSB) Federal Contract Program is administered by the U.S. Small Business Administration and enables federal agencies to set aside contracts specifically for women-owned small businesses. To qualify, a business must be at least 51% owned and controlled by one or more women who are U.S. citizens, and must meet the SBA's small business size standards for the relevant industry. Nationwide Maintenance meets all SBA WOSB requirements — enabling participation in federal contracting set-asides across the facility maintenance and general contracting categories.

What It Means for Your Procurement

For federal government agencies and state agencies using federal procurement standards, SBA WOSB certification qualifies Nationwide Maintenance for women-owned small business set-aside contracts and procurement preferences. Combined with our WBENC certification, Nationwide Maintenance satisfies WBE vendor requirements across both the corporate and government procurement ecosystems.

Cert · 03

Better Business Bureau (BBB) Accreditation

Verify at BBB.org

What It Is

BBB Accreditation is awarded by the Better Business Bureau to businesses that meet the BBB's standards for trust — including commitment to make a good faith effort to resolve any consumer complaints, transparency, honesty in advertising, and maintenance of a positive complaint resolution record. BBB accreditation is not automatic — it requires application, review, and ongoing compliance with BBB standards.

What It Means for Your Procurement

BBB accreditation provides an independent third-party validation of Nationwide Maintenance's business practices, complaint history, and commitment to customer resolution. For procurement teams conducting vendor due diligence, BBB accreditation is a recognized trust indicator that complements our certification credentials and client reference documentation.

Why WBE Certification Matters for Your Organization

For Fortune 500 Companies

Many Fortune 500 companies operate formal supplier diversity programs that require a percentage of procurement spending to go to certified diverse suppliers — including women-owned businesses. Nationwide Maintenance's WBENC certification satisfies this requirement across the full range of facility maintenance services we provide — cleaning, pest control, construction, landscaping, handyman services, parking lot maintenance, and all other services in our portfolio. Engaging Nationwide Maintenance for facility maintenance services directly contributes to your organization's supplier diversity spending targets.

Companies that have engaged Nationwide Maintenance as a certified WBE supplier include Bloomingdale's, CVS, Macy's, Whole Foods, Costco, Shake Shack, and other recognized national brands. View our full client references.

For Government Agencies

Federal, state, and municipal government agencies operate procurement programs that include set-asides and preferences for women-owned small businesses. Nationwide Maintenance's SBA WOSB certification qualifies us for these set-asides, and our WBENC certification is accepted by state and local government procurement programs across New York, New Jersey, and Connecticut. Government facility maintenance contracts, renovation projects, and service agreements with Nationwide Maintenance satisfy WBE and WOSB procurement requirements without any additional verification steps.

Government clients served include USPS, the NY Federal Reserve, and public libraries and municipal facilities throughout the Tri-State area.

For Large Commercial Operators

Beyond formal diversity programs, WBE certification signals organizational stability, management accountability, and the governance standards that rigorous certification processes require. Working with a certified WBE partner also supports your organization's broader corporate social responsibility and supplier diversity reporting — an increasingly important element of ESG compliance and stakeholder reporting for large commercial operators.
