Staffing & HR Services sector
Supplier diversity in staffing & hr services.
The U.S. staffing industry generated over $207 billion in revenue in 2024, providing jobs to approximately 13 million employees. Staffing Industry Analysts (SIA) identified 223 diversity-owned staffing firms on their 2024 list, but this represents a small fraction of the market. Major corporations and government agencies actively seek diverse staffing suppliers, making certification a powerful differentiator in this massive, growing industry.

Why certification matters here
What certification opens for staffing & hr services suppliers.
Staffing and HR services is a massive market where diverse suppliers are actively sought. Here's why certification matters:
Corporate Staffing Mandates: Fortune 500 companies routinely include diverse staffing supplier requirements in their Managed Service Provider (MSP) and Vendor Management System (VMS) programs. Without certification, you may be excluded from corporate staffing vendor lists entirely.
Federal Staffing Contracts: The federal government is a major purchaser of temporary and contract staffing services, with set-asides for 8(a), WOSB, SDVOSB, and HUBZone firms across multiple agencies.
SIA Recognition: Staffing Industry Analysts publishes an annual Diversity-Owned Staffing Firms list. In 2024, 223 firms were recognized. Being on this list and holding certifications increases visibility with large corporate and MSP buyers.
MSP/VMS Access: Most large corporations use MSPs (like Allegis, Hays, or Kelly) and VMS platforms (Fieldglass, Beeline, Pontoon) to manage contingent labor. Certified diverse staffing firms receive preferential inclusion in these programs.
Performance Advantage: Harvard Business Review research shows that small and diverse suppliers awarded federal set-aside contracts perform better—with lower cost overruns and shorter delays—than comparable non-diverse suppliers. This data supports the business case for diverse staffing partners.
Growing Market: Despite industry size, diverse suppliers hold a small share of the staffing market, creating significant growth opportunity for certified firms willing to invest in the sector.

FAQ
Questions staffing & hr services owners ask.
How do I get on a corporate staffing vendor list? +
Most large corporations manage temporary staffing through MSPs (Managed Service Providers) and VMS (Vendor Management System) platforms. To get on the vendor list, you need: 1) NMSDC or WBENC certification, 2) registration in the VMS platform the client uses (SAP Fieldglass, Beeline, etc.), 3) compliance documentation (insurance, workers comp, E-Verify). Contact the MSP's diverse supplier program manager to begin the process.
What is a VMS and how does it affect diverse staffing suppliers? +
A VMS (Vendor Management System) is a technology platform that manages a company's contingent workforce procurement. Major platforms include SAP Fieldglass, Beeline, and Coupa. Companies release job requisitions through the VMS, and approved staffing vendors submit candidates. Being a certified diverse supplier often gives you preferred status or guaranteed access to requisitions in these systems.
How do I fund payroll when clients pay in 30-60 days? +
Payroll funding is the biggest challenge for staffing startups. Options include: 1) Traditional bank line of credit, 2) Staffing-specific factoring companies (they advance 80-90% of invoice value), 3) SBA loans, 4) Staffing industry lenders like Advance Partners or eCapital. Factor your funding costs into your bill rates. Many staffing firms use factoring for their first 1-3 years until they build sufficient reserves.
What insurance do I need for a staffing company? +
At minimum: general liability ($1M-$2M), workers compensation (required by law in most states), professional liability/E&O, employment practices liability (EPLI), and commercial auto if transporting workers. Workers comp is your largest insurance cost and varies by state and job classification. Use staffing-industry insurance specialists who understand classification codes and experience modification rates.
Should I specialize in a staffing niche or offer broad services? +
Specialize. Staffing is a relationship and expertise business—you cannot be excellent at recruiting software engineers AND warehouse workers AND nurses. Pick a niche aligned with your experience and network: IT, healthcare, industrial, administrative, or professional/financial. You can expand to adjacent niches after establishing a strong reputation and track record in your primary specialty.
