Other Computer-Related Services (NAICS 541519) is a catch-all classification for IT services that don't fit cleanly into other NAICS codes. This includes IT consulting, IT staffing services, IT portfolio management, and specialized technology support services. Many IT services companies use 541519 as a secondary NAICS code to capture opportunities that don't fit primary codes.

What Businesses Fall Under This Code

541519 covers IT consulting, IT strategy development, technology staffing services, IT portfolio management, and specialized support. This is a broader classification that captures IT services not specifically classified as development, systems integration, or specific technical areas. Examples include IT consulting for digital transformation, IT security consulting (distinct from implementation), and IT staffing services.

SBA Size Standard and What It Means

The SBA size standard for 541519 is $34 million in average annual receipts. With average annual receipts of $34 million or less, you count as a small business on contracts filed under this code. Some work under this code has its own standard: Information Technology Value Added Resellers (150 employees).

Federal Spending in This Category

Federal spending in miscellaneous IT services exceeds $25 billion annually. This is spread across specialized consulting, staffing, portfolio management, and technology advising services. Many smaller IT consulting firms find their primary revenue here.

Top Agencies Buying in This Code

All major federal agencies procure services classified under 541519. DoD, DHS, VA, and civilian agencies all use IT consultants for strategy, planning, and specialized technology support. The General Services Administration (GSA) and Federal CIO Council drive significant consulting spending government-wide.

Tips for Tech Companies Using This Code

Use 541519 as a secondary code to capture diverse IT service opportunities. If you're a management consulting firm offering digital transformation services, include 541519. If you're a staffing company providing IT professionals, 541519 may be more appropriate than development codes. Position your company's unique expertise—IT portfolio management, digital transformation, technology strategy, or specialized consulting.

Pro Tip: 541519 is best as a secondary NAICS code. If this is your primary code, consider whether you should register for more specific codes (541511, 541512, 541513) to be visible to agencies searching those specific categories.
