Under the schedules program, buyers receive the “most favored customer pricing,” and enjoy shorter acquisition lead-times, lower administrative costs, and reduced inventories. In addition to ensuring competitive price points versus those found on the open market, services can be purchased with reduced administrative burden using the GSA Advantage Online Shopping Service. QSI’s MAS contracts allow for competitive pricing against multiple GSA contractors using the GSA e-Buy Request for Quote (RFQ) tool. Using the RFQ tool, customers can obtain our services using a more standard comparison bidding process.

Whenever or whatever your needs, QSI’s MAS Contracts provide your agency with the tools to order industry-leading professional, technical and managerial services.

For assistance with QSI GSA Contracts: Please contact our GSA Administrators, Dan Dumlao or Valerie Valdez or call (210) 212-8784.
