GSA Multiple Award Schedule — Large Categories

GSA MAS Category 1 covers office management solutions including office supplies, office equipment, printing services, and records management. This category consolidates products and services that federal agencies need for day-to-day administrative operations, from pens and paper to high-volume copiers and document destruction services. It represents one of the most frequently ordered categories on GSA Advantage.

GSA MAS Category 2 encompasses facilities maintenance and management solutions including HVAC, plumbing, electrical, janitorial services, pest control, and building management systems. This category supports the government's massive real property portfolio — over 376,000 buildings and structures — making it one of the most critical categories for keeping federal facilities operational and compliant with environmental and safety standards.

GSA MAS Category 3 covers all types of furniture, furnishings, and floor coverings for federal workplaces, including systems furniture, seating, filing solutions, dormitory and quarters furnishings, and installation services. The category supports both traditional office environments and modern collaborative workspaces, with growing emphasis on ergonomic solutions, modular configurations, and sustainability (FSC-certified wood, recycled materials).

GSA MAS Category 4 provides industrial products and services including tools, hardware, paints, adhesives, material handling equipment, and industrial maintenance supplies. This category serves federal agencies with manufacturing, maintenance, and construction needs, from military depot-level repair to national park facility maintenance. It includes both commercial-off-the-shelf products and specialized industrial solutions.

GSA MAS Category 5 is the largest and most complex MAS category, encompassing all information technology products, services, and solutions. It includes hardware (laptops, servers, networking), software (COTS, SaaS, cloud), IT services (development, cybersecurity, managed services), and telecommunications. Category 5 is the primary vehicle for federal IT modernization and cloud migration initiatives.

GSA MAS Category 6 provides security and protection equipment and services including physical security systems, guard services, law enforcement equipment, fire protection, cybersecurity products, and personal protective equipment (PPE). Post-9/11 security requirements and the growing cybersecurity threat landscape have made this one of the fastest-growing MAS categories.

GSA MAS Category 7 covers transportation, logistics, and vehicle-related products and services including fleet vehicles, vehicle parts, shipping and freight services, fleet management, and vehicle maintenance. GSA Fleet (the largest civilian fleet in the federal government) and DoD vehicle programs are the primary drivers of Category 7 spending, with growing emphasis on electric and alternative fuel vehicles.

GSA MAS Category 8 encompasses a broad range of professional services including management consulting, engineering, environmental services, financial management, marketing and communications, logistics, and training. This category is the primary vehicle for agencies seeking expert advisory services that do not fall under IT (Category 5) or scientific research (Category 11).

GSA MAS Category 9 covers travel-related services including travel management, lodging, conference and event planning, relocation services, and travel agency services. The Federal Travel Regulation (FTR) and city-pair airfare programs set the framework within which Category 9 contractors operate, supporting millions of federal employee trips and permanent change of station (PCS) relocations annually.

GSA MAS Category 10 is a catch-all category for products and services that do not fit neatly into other MAS categories. It includes agricultural supplies, textiles, clothing, recreational equipment, musical instruments, ecclesiastical equipment, and specialized products for unique government needs. While smaller in spend than major categories, Category 10 addresses niche requirements across diverse federal missions.

GSA MAS Category 11 provides scientific, laboratory, medical, and management equipment used across federal research laboratories, healthcare facilities, and analytical operations. It includes laboratory instruments, medical devices, test and measurement equipment, and environmental monitoring systems. Category 11 supports agencies from NIH and CDC to DOE national laboratories and DoD research facilities.

GSA MAS Category 12 covers human capital management solutions including staffing services, HR consulting, workforce development, executive coaching, employee assistance programs (EAPs), and organizational development. This category supports federal agencies' workforce transformation, talent acquisition, and employee development initiatives in an increasingly competitive labor market.

OASIS+ is GSA's premier government-wide acquisition contract (GWAC) for complex professional services spanning multiple NAICS codes and disciplines. Replacing the original OASIS contracts, OASIS+ provides a single-award vehicle for multidisciplinary services including management consulting, engineering, scientific research, logistics, and financial advisory. The "plus" denotes expanded scope and simplified ordering procedures introduced in the 2024 re-compete.

Alliant 3 is GSA's next-generation IT services government-wide acquisition contract, succeeding Alliant 2. It provides federal agencies with access to IT services including systems integration, cybersecurity, cloud migration, agile development, and emerging technology solutions. Alliant 3 features a multi-pool structure with separate unrestricted and small business tracks, and incorporates lessons learned from the Alliant 2 program.

8(a) STARS III is GSA's government-wide acquisition contract exclusively for 8(a)-certified small businesses providing IT services. It enables federal agencies to issue sole-source and competitive task orders to 8(a) firms for IT modernization, cybersecurity, software development, and managed services. The STARS program has been instrumental in channeling billions in IT spending to small disadvantaged businesses.

VETS 2 is GSA's government-wide acquisition contract providing IT services exclusively through service-disabled veteran-owned small businesses (SDVOSBs). The vehicle supports federal agencies in meeting their 3% SDVOSB contracting goals while accessing high-quality IT services. VETS 2 covers the full range of IT services from help desk and managed services to enterprise architecture and cybersecurity.

Polaris is GSA's newest small business IT government-wide acquisition contract, designed as the next generation of vehicles like 8(a) STARS III and VETS 2. Polaris consolidates small business IT contracting into a unified vehicle with separate pools for HUBZone, SDVOSB, WOSB, and general small business categories. It is designed to maximize small business participation in the estimated $100 billion annual federal IT market.

A specialized subset of GSA MAS Category 11, the Healthcare Products and Services subcategory addresses the unique procurement needs of VA medical centers, DoD military treatment facilities, Indian Health Service, and other federal healthcare providers. It covers medical devices, pharmaceuticals (through the Federal Supply Schedule for pharmaceuticals), surgical instruments, diagnostic equipment, and healthcare consulting services.

The Environmental Services subcategory within GSA MAS Category 8 covers environmental remediation, hazardous waste management, NEPA compliance, environmental impact assessments, sustainability consulting, and climate resilience services.

It includes body cameras, forensic equipment, less-lethal weapons, emergency communications, and law enforcement training services.

The Energy Management and Sustainability subcategory within GSA MAS Category 2 supports federal energy efficiency mandates, renewable energy installations, and building performance optimization. With Executive Orders requiring federal buildings to achieve net-zero emissions by 2045, this subcategory encompasses energy audits, building automation systems, solar and wind installations, EV charging infrastructure, and energy savings performance contracts (ESPCs).

The Cloud Marketplace is a specialized subset of GSA MAS Category 5 that consolidates cloud computing offerings including Software as a Service (SaaS), Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and associated cloud professional services. FedRAMP authorization is mandatory for cloud offerings on the MAS program, ensuring security compliance for government data in cloud environments.
