§ 01 · Government

In government procurement.

How a contracting officer reads this code.
SAM.govUEI PR9KWJPM4JU9 · CAGE 91CE1 · 541512 is a primarycode on ITC's registered entity record.

Agencies use 541512 for systems-design and integration work: assessing requirements, designing the target architecture, and integrating hardware and software into a working system. It overlaps 541511 but sits a layer up, at the design and integration tier rather than the line-by-line build. It is a primary code on ITC’s SAM.gov record and a frequent vehicle for cloud-migration and modernization requirements where the agency wants a designed approach, not just developers.

§ 02 · Commercial

The same capability, commercially.

Mid-market, SMB, enterprise, and prime-subcontract buyers.
Note 02.AA NAICS code only matters when the buyer is a government agency. The capability is the same for private-sector buyers.

For commercial buyers this is the work that happens before a migration or a platform change: landing-zone design, workload classification, and the integration plan between the systems a company already runs. ITC delivers on Cloudflare, AWS, and Azure with documented US-East data residency through its own product stack. A mid-market firm consolidating tools, or a prime contractor that needs a subcontractor to own an integration workstream, buys this capability on its merits without a NAICS filter.

§ Who buys this
  • · Federal agencies and SLED

  • · Multi-location and distributed operations

About NAICS 541512.

What is the difference between NAICS 541512 and 541511?

541512 (Computer Systems Design) covers design and integration of a working system; 541511 (Custom Computer Programming) covers the software written to spec. A project can touch both: 541512 for the architecture, 541511 for the build.

Does 541512 cover cloud migration?

Yes. Migration planning, landing-zone design, and integration of cloud and on-premise systems fall under 541512. ITC delivers this on Cloudflare, AWS, and Azure.

Can this capability be bought commercially?

Yes. Systems design and integration are sold to commercial buyers on capability, not on procurement code. The NAICS only matters when the buyer is a government agency scoping a solicitation.

§ Need code-aligned help?

Send the solicitation.

We'll confirm the right NAICS and PSC for your scope, government or commercial.
