Benchmarking Insights for Professional, Scientific, and Technical Services

When you read the financial profile for Professional, Scientific, and Technical Services, the number only becomes actionable when paired with scale. This industry sits inside the broader Professional, Scientific, and Technical Services sector and reports N/A of aggregate annual receipts. Owners comparing their own books should read the margin as a midpoint — smaller operators typically run several points below the aggregate because fixed overhead (rent, software, insurance) consumes a larger share of lower revenue bases. Treat the industry figure as a ceiling calibrated by businesses that have already achieved operating leverage.

Labor economics tell the second half of the story. Census CBP shows 11,483 active establishments employing N/A workers. Florida leads the geographic distribution of employment, with Pennsylvania and Ohio rounding out the top three concentrations. Headcount density matters because thin-margin industries only clear the cash-flow bar when establishments reach the staffing level where fixed costs amortize — a useful cross-check against the margin line above.

Capital access is the third lens. SBA 7(a) and 504 approvals for this industry totaled 513 loans worth $89 million between FY2020 and FY2025, supporting 2,427 jobs at origination. The average ticket size — $173K — signals the typical capital gap operators bridge when expanding. Newtek Bank, National Association ranks as the most active SBA lender serving this NAICS code. Use this alongside the IRS and Census figures to decide whether your own plan should target operational efficiency, workforce expansion, or financed growth.
