Joined at the hip
CBIZ and Mayer Hoffman McCann P.C. (MHM) are independent
businesses, associated through an alternative practice structure;
this means they work jointly to provide services to their clients.
Together, CBIZ and MHM are the 11th largest accounting provider in
the U.S. (according to Accounting Today's 2014
ranking of the largest firms by revenue). MHM is an
independent CPA firm providing audit, review, and attest services,
and works closely with CBIZ, a business consulting, tax, and
financial services provider. For the combined firms,
accounting services bring in approximately 25 percent of revenue;
tax services are responsible for 41 percent; and advisory and other
services make up about 34 percent.
MHM's roots date back to 1954 when Ernest D. Mayer opened an
accounting practice in Kansas City, Mo. Mayer later merged his
practice with one owned by Bill Hoffman. In 1978, Chuck McCann
joined the firm and the name changed to Mayer Hoffman McCann P.C.
In 1998, MHM spun off its tax and consulting practice to Century
Business Services, Inc., now known as CBIZ.
CBIZ was founded in 1996 as a result of the merger between
Republic Environmental Systems and CBIZ Surety Group. The two
companies combined to become International Alliance Services, Inc.
(IASI). In December 1997, IASI changed its name to Century Business
Services, Inc. Often referred to as "CBIZ" due to its Nasdaq symbol
of the same name, the company legally changed its name to CBIZ,
Inc. in August 2005. CBIZ began trading on the New York Stock
Exchange in August 2006 under the symbol "CBZ."
Today, CBIZ and MHM have nearly 3,000 associates, including more
than 420 partners.
