NAICS 561110: Office Administrative Services

NAICS 561110 – Office Administrative Services encompasses a broad spectrum of non-clinical, back-office support functions critical to federal agency operations. This category includes administrative management services such as records management, document processing, scheduling, mail and fleet logistics, human resources support, financial administration, and facility coordination. These services enable mission-critical agencies to maintain operational efficiency without diverting personnel from core functions. In the federal contracting landscape, this NAICS serves as an essential enabler for large-scale, complex organizations that require scalable, compliant, and secure administrative infrastructure—often integrated with enterprise resource planning systems and automated workflow platforms. Top contractors in this sector include a mix of large primes and specialized small businesses, with D2 Government Solutions, Inc., Deloitte Consulting LLP, and B3H Corporation leading in award volume. Other active players such as SunTiva LLC, Innovation at Work Inc., and Red Carrot Inc. demonstrate strong niche capabilities in federal administrative modernization, often leveraging cloud-based tools and process automation. The competitive landscape is characterized by high participation from small businesses and service-disabled veteran-owned firms, reflecting strong set-aside opportunities under SBA programs. Primary buyers include the Department of Defense across multiple branches—including the Marine Corps, Air Force, and Naval Medical Clinic—as well as the Department of Homeland Security, Department of State, and agencies like NASA, the NSF, and the VA. Demand is driven by mission continuity initiatives, workforce modernization, and the need for compliant, audit-ready administrative systems across decentralized operations. The market offers dense opportunity density, particularly for contractors with experience in federal compliance frameworks like FISMA, NIST, and FAR Part 12. Trends indicate growing demand for hybrid administrative models that blend human expertise with digital workflow automation, creating openings for firms skilled in both process design and federal procurement compliance.
