when people understand how they fit into the overall scheme and what their role is and grasp the essentials of how the organization operates, they produce higher quality work and are more energized.

cpa firms are no exception.

and it starts with the partners:

  • partners should be formally educating their staff on the business of public accounting, how firms are structured, what makes them successful, how firms are managed, how they get clients, what makes them profitable, and how profitability is held back.
  • staff who aspire to become partners should understand all of the topics listed above. if the firm doesn’t proactively offer this education, then they should take it upon themselves to acquire this knowledge.

services provided by cpa firms

cpa firms typically provide three main types of services, with each service having several subgroups. the mix of these three main services is shown underneath, broken down by size of firm:

  • big 4 (deloitte, pwc, ernst & young and kpmg)
  • large regional firms. these are roughly the largest 50 firms in the u.s. beyond the big 4. though an increasing number of these firms have become quasi-national firms, most are regional, based in the northeast, midwest, southeast, southwest or another region. the 50th largest firm in the country has annual revenue of roughly $100 million.
  • local firms. these are multi-partner firms below the regionals. most have one or two offices.

(5) the term “handholding” is colloquially used to describe arguably the most important work that cpas do for their clients. cpas are their clients’ most trusted advisors. clients seek advice from them in a wide variety of areas, such as estate planning, paying for college, getting a business loan, hiring a controller, buying a company, investing their money, choosing what kind of insurance to buy … the list is endless.

the u.s. cpa firm market

there are roughly 44,000 cpa firms in the united states. the market is skewed significantly from large to small:

  • the big 4 international firms (ernst & young, kpmg, pwc and deloitte) account for 46 percent of the industry’s total revenue.
  • there is a huge fall-off from the big 4 to the next tier of firms: the smallest big 4 firm is five times the size of the fifth-biggest firm.
  • the 200 largest firms account for 65 percent of the industry’s total revenue.
  • the vast majority of the 44,000 firms are very small; most employ well under 10 total people.
  • roughly 30,000 of the 44,000 firms are sole practitioners. most are one-person operations but many have several employees.

the demographics of the 44,000 firms are summarized here.

i am unaware of any authoritative, exact source for the revenue size of the 44,000 cpa firms. the above is a very good guess. however, the point of the chart is to show how a relatively small number of firms dominate the market in terms of revenue. three hundred firms comprise 67 percent of the market.
