Award counts and obligations are both scoped to NAICS 541620 only — not a company’s total federal portfolio, and not a claim that the underlying work matches this code’s title beyond what the code itself covers. Companies are resolved to the platform’s own production family-root spine, and an identical registered name appearing under two legal registrations is merged into one row — a small number of near-duplicate registrations (a punctuation or naming variation the spine has not yet linked) may still appear separately. A set-aside badge renders ONLY when the company’s OWN current federal registration confirms it holds that status today; an unconfirmed status is never displayed. Designation badges are never a size determination this platform makes.
This page ranks NAICS 541620 the way the federal government’s own records break it down: total obligations under this one code, summed across the last five completed fiscal years — never a contract ceiling, and never a claim about who does the best work. It does not, and cannot, tell you whether a company can actually run this kind of engagement, who they’ve done that work for, or how they’d fit on a team next to you.
That read takes more than a NAICS code: demonstrated capabilities pulled from these companies’ own contract descriptions and performance work statements, their customer relationships, every filter by revenue division and certification, and a full profile for anyone on this page.
Plus the labor rates behind the prices, the Other Transactions most tools never touch, and buying-office intelligence behind every customer.
That’s the data we put at your fingertips.
