Systems Integration Design Services (NAICS 541513) covers companies that design, integrate, and architect complex technology systems across organizations. This code applies to systems integrators, enterprise architects, and consulting firms that help federal agencies plan and implement large-scale IT transformations.
What Businesses Fall Under This Code
541513 includes systems integrators, enterprise architects, and IT consultancies focused on large-scale implementations. This is distinct from development services (541511/541512) in that the focus is architectural planning, integration of multiple systems, and transformation design rather than coding specific applications. Examples include companies designing federal data centers, integrating agency applications, or architecting cloud migrations.
SBA Size Standard and What It Means
The SBA size standard for 541513 is $37 million in average annual receipts. With average annual receipts of $37 million or less, you count as a small business on contracts filed under this code.
Federal Spending in This Category
Federal systems integration spending exceeds $30 billion annually. This includes major modernization initiatives (like VA's Cerner EHR implementation, IRS modernization, DoD cloud migration) that require systems integrators to coordinate complex implementations across multiple vendors and legacy systems.
Top Agencies Buying in This Code
The Department of Veterans Affairs, Department of Defense, Internal Revenue Service, Social Security Administration, and Department of Energy are major spenders. These agencies undertake massive IT transformation initiatives requiring systems integration expertise. The Defense Information Systems Agency (DISA) and General Services Administration (GSA) also procure systems integration services.
Tips for Tech Companies Using This Code
Position your company as a trusted integrator who can coordinate complex implementations. Show experience managing multi-vendor environments, complex migrations, and large-scale implementations. Federal agencies want systems integrators who understand federal compliance, security requirements, and can navigate procurement processes with multiple stakeholders.
Pro Tip: 541513 is best positioned for mid-size to larger firms with proven enterprise track records. If you're a small startup in custom development, focus on 541511/541512 first. As you grow, add 541513 to position for larger systems integration opportunities.
