NAICS Code 541512: Computer Systems Design Services for Government Contracts

What Is NAICS Code 541512?

NAICS code 541512 — Computer Systems Design Services covers businesses that plan and design computer systems that integrate hardware, software, and communications technologies. This includes companies that provide IT consulting, systems integration, network design, and custom software development as part of a broader systems design engagement.

If your business helps organizations plan, design, or implement computer systems — whether that's migrating to the cloud, building out network infrastructure, or integrating enterprise software — this is likely your primary NAICS code.

What Services Fall Under 541512?

The Census Bureau defines 541512 to include:

• Computer systems integration design consulting services
• Local area network (LAN) and wide area network (WAN) design consulting
• Office automation planning and design
• Hardware and software consulting combined with systems design
• Turnkey computer systems integration
• Information management system design and consulting (except hardware or software only)

The key distinction is that 541512 covers integrated systems design — if you're providing both the planning and implementation of systems that combine hardware, software, and networking, this is your code. If you only write custom software, that falls under 541511 (Custom Computer Programming Services). If you only provide IT support, that's 541513 (Computer Facilities Management Services).

541512 SBA Size Standard

The Small Business Administration (SBA) size standard for NAICS 541512 is $34 million in average annual receipts. This means your company qualifies as a "small business" for government contracting purposes if your average annual revenue over the past 3-5 years is below $34 million.

This is one of the higher revenue thresholds in the professional services category, which means many mid-sized IT consulting firms still qualify as small businesses for set-aside contracts.

Set-Aside Programs for 541512

If your company qualifies as small under the 541512 size standard, you're eligible for several set-aside programs that limit competition to small businesses:

• Small Business Set-Aside — Open to all qualifying small businesses

• HUBZone — For businesses in Historically Underutilized Business Zones
• SDVOSB — Service-Disabled Veteran-Owned Small Business
• WOSB / EDWOSB — Women-Owned Small Business / Economically Disadvantaged WOSB
