What this NAICS code covers

NAICS 541519 is the North American Industry Classification System code that federal contracting officers assign to other computer related services work. The code determines your small-business size standard for any solicitation issued under it, which in turn determines whether you can compete as a small business or pursue any of the socioeconomic set-aside programs.
