The US professional services industry includes about 890,000 establishments (single-location firms and units of multi-location firms) with combined annual revenue of about $1.6 trillion.
Demand is driven by corporate profits and the overall health of the US economy. Although some professional services are necessary for the normal functioning of most companies, many services can be postponed during economic downturns. The profitability of individual firms depends on having a regular flow of projects.

Small firms can compete successfully by offering special expertise or focusing on particular regions. The US industry is highly fragmented: the 50 largest firms account for less than 20% of revenue.
