Robert Half International ranks as the largest supplier of finance/accounting temporary staffing in the US with one-quarter of the market share, according to a new report released by Staffing Industry Analysts. The annual list of largest US finance/accounting firms includes companies with revenue of at least $50 million in the US finance/accounting staffing segment in 2014. This year’s list included 13 firms.

The market share of the five largest finance/accounting staffing firms increased shortly after the most recent recession, in part due to the acquisition of MPS Group by Adecco, but has stayed roughly the same over the past three years.

The five largest finance/accounting staffing firms in the US and their estimated 2014 staffing revenue are:

• Robert Half International: $1.70 billion, 25% market share
• Accounting Principals (Adecco): $335 million, 5% market share
• Randstad Professionals: $310 million, 5% market share
• Kforce: $276 million, 4% market share
• RGP (Resources Connection): $200 million, 3% market share

Two firms appear in this year’s report that did not appear in last year’s ranking: Digital Intelligence Systems (DISYS) and Addison Group.
