GSA’s Office of Assisted Acquisition Services (AAS) provides custom acquisition, project, and financial management support services to federal agencies. We help you acquire the services you need to advance your mission, guiding you through every stage of the acquisition process.

We are organized as a Client Support Center housed within the General Services Administration’s (GSAs) Federal Acquisition Service (FAS). Learn more about GSA's organization by viewing this chart.

We support the full spectrum of the acquisition lifecycle, so you can focus less on acquisition management and more on your agency's core mission activities. To execute the GSA FAS AAS mission, our national and regional Client Support Centers (CSC) integrate together to support client mission requirements.

Our acquisition, financial, and project management experts develop creative solutions to ensure quality and compliance throughout the life cycle of each acquisition.
