NAICS Code for Management Consulting
Management consulting to the federal government is a high-volume, high-competition NAICS category. The choice between 541611 and 541618 affects which contracts you see and how long you stay small under SBA size standards. Most small consulting firms get this wrong by defaulting to 541611 without checking whether 541618 is a better fit.
Primary NAICS codes for management consulting
541611: Administrative Management and General Management Consulting Services ($24.5M size standard) Use this for general management consulting: organizational design, strategy, operations improvement, change management, executive advisory. This is the default primary for most management consulting firms.
541618: Other Management Consulting Services ($19.5M size standard) Use this for specialized management consulting that doesn't fit under 541611. Logistics consulting, supply chain advisory, and specialized operational consulting often fit here.
541612: Human Resources Consulting Services ($14M size standard) Use this for HR-focused consulting: workforce planning, compensation design, benefits consulting, talent management.
541614: Process, Physical Distribution, and Logistics Consulting Services ($19.5M size standard) Use this for logistics and supply chain consulting, distribution strategy, and process optimization focused on physical operations.
Secondary NAICS codes to consider
541690: Other Scientific and Technical Consulting Services ($19M) For technical consulting that touches management but isn't pure strategy work.
541990: All Other Professional, Scientific, and Technical Services ($17M) Catch-all for consulting services that don't fit elsewhere. Not recommended as primary.
611430: Professional and Management Development Training ($12.5M) For consulting firms whose work includes significant training delivery.
541720: Research and Development in the Social Sciences and Humanities ($25M) For consulting firms doing applied social science research, policy analysis, and program evaluation.
Which code should be your primary
The 541611 vs 541618 decision is the main one.
541611 (General Management Consulting) is broader and captures more federal search results, but the size standard is higher ($24.5M vs $19.5M) which means you stay small longer. Most general management consultants primary here.
541618 (Other Management Consulting) is narrower but less competitive. If your work is specialized enough to sit under 541618, you're competing against a smaller pool of contractors. The tradeoff is the lower size standard.
Rough rule: if your work is truly general strategy and operations consulting, primary under 541611. If your work has a specialized operational or technical focus that fits 541618, primary there and take advantage of the reduced competition.
HR consulting and specialized NAICS
If HR work is your core service, primary under 541612 rather than 541611. The size standard is smaller ($14M) but HR-specific set-asides and procurement searches filter by that code. Primary NAICS drives which searches find you.
Same logic applies to logistics consulting (541614) and training delivery (611430). Specialized codes have lower competition if they match your work.
Federal demand snapshot
Every federal agency buys management consulting. The largest spenders are DoD, DHS, HHS, Treasury, and VA. Professional Services Schedule (PSS) and OASIS+ are the dominant contract vehicles.
SDVOSB set-asides are consistent across management consulting NAICS, particularly at VA and DoD.
