Overview of GSA PSS

The GSA PSS consolidates multiple service schedules into a single contract vehicle, making it easier for federal buyers to procure integrated professional services. PSS is available to all federal agencies and can be used for both DoD and civilian requirements. Orders placed under PSS can be firm-fixed-price, time-and-materials, or labor-hour contracts, depending on agency needs. 

Scope of Services Available Under PSS

ABSI’s offerings under PSS include:
  • Program management and consulting services

  • Engineering and technical services

  • Logistics and administrative support

  • Training program development and delivery (including sUAS operator training)

  • Acquisition and program office support services

  • Professional staffing solutions

Through PSS, agencies can obtain ABSI’s expertise quickly using pre-negotiated rates and terms. This simplifies acquisition planning while ensuring compliance with the Federal Acquisition Regulation (FAR).

Together, these divisions make ABSI a flexible, capable provider under PSS.
