GSA Schedule for Staffing Companies: SINs and Requirements
Staffing and temporary labor companies can access the federal market through the GSA Multiple Award Schedule, primarily through SINs covering human capital services. The federal government uses contingent workforce solutions extensively — agencies need temporary IT professionals, administrative staff, subject matter experts, and specialized labor for programs that cannot sustain full-time headcount. The GSA Schedule provides the vehicle to compete for this work.
Primary SINs for Staffing Companies
The most relevant SINs for staffing firms include SIN 736 (Temporary and Term Employment of Technical, Professional, and Management Personnel) and SIN 54151S for IT staffing specifically. Some staffing companies also hold SINs under the Professional Services Schedule (PSS) for longer-term consulting engagements. SIN 736 covers temporary placement of staff in administrative, technical, and professional roles across a wide range of agencies. Rates are typically expressed as fully loaded hourly rates by labor category and may include markup/fee structures common to staffing industry pricing.
Staffing Pricing Structure on the Schedule
Staffing companies on the Schedule price their offerings in one of two common ways: (1) loaded hourly rates by labor category that include the worker's compensation, benefits, overhead, and fee; or (2) a pricing structure that separates the base wage from a markup percentage. Many Schedule contracting officers prefer fully loaded rates because they simplify price evaluation. Ensure your rates are built to include the 0.75% IFF and that your labor category definitions clearly specify minimum qualifications so buyers understand what they're paying for at each rate tier.
| Labor Category Type | Typical Pricing Model |
|---|---|
| Administrative/clerical | Loaded hourly rate by seniority level |
| IT professionals | Loaded hourly by skill set and clearance level |
| Professional (legal, finance) | Loaded hourly by credentials and experience |
| Management/executive | Fixed-fee or loaded hourly (project-based) |
Clearance Requirements and Staffing
Many federal staffing requirements involve positions requiring security clearances. If your staffing company provides cleared personnel, this is a significant differentiator — there is persistent demand for cleared IT professionals, program analysts, and administrative personnel across DoD, IC, and civilian agencies. Note the clearance level (Secret, Top Secret, TS/SCI) in your labor category descriptions and in any RFQ responses where clearance is specified. Agencies pay a premium for cleared staff and often prefer vendors who have established their own facility clearance (FCL).
