GSA Professional Services Schedule


The Professional Services Schedule (PSS) consolidates GSA’s professional-services Multiple Award Schedules into a single contract. GSA created the PSS to give federal-agency acquisition professionals the ability to obtain total contract solutions for their professional-services needs using a single contract vehicle. Agencies have access to the same professional services as before–but in an easier-to-use contract environment. Also, for both industry and GSA, PSS eliminates significant contract duplication and workload previously associated with negotiating, administering, and auditing multiple contracts.

Benefits of the Professional Services Schedule

PSS gives federal agencies the ability to use a single contract to procure simple to complex fixed-price or labor-hour professional services. When using PSS to acquire professional services, agencies can:

  • Use simplified acquisition procedures to issue a Request for Quotation (RFQ) using either their agency’s solicitation system or GSA’s eBuy solicitation system, or issue an RFQ directly to contractors using their agency’s procedures.
  • Allow unique Contractor Team Arrangements to bring a wide variety of industry partners to the negotiating table.
  • Customize terms and conditions in task orders–or through Blanket Purchase Agreements (BPAs)–to meet specific requirements.
  • Be assured that required FAR terms and conditions are incorporated into the contract.
  • Ensure adequate participation by small businesses, including setting aside RFQs for various socioeconomic subgroups, excluding 8(a) set-asides.
  • Save time by using the streamlined procurement procedures of FAR Subpart 8.4.

How the Professional Services Schedule Works

RFQs can be issued to contractors by Special Item Number (SIN) or solution set (e.g., Financial and Business Solutions), including contractors awarded complementary SINs (e.g., IT, HR, and energy-management services) under PSS.

Who Can Order through the Professional Services Schedule?

All federal and appropriately warranted Contracting Officers are authorized to award task orders against PSS.
