According to the US Census Bureau Statistics of US Businesses, the average company in the US has 15.9 employees. I would assume, since Paychex processes payroll for 564,000, their average current client size would match that of what the actual national average is.  
 
 
 
If you continue to do some research, you will find that the largest 30,000 clients (about 18% of their clients)that Paychex processes payroll for average 140 employees. Comparing that again the the US Census Bureau numbers, Employers that have between 100-499 employees make up approximately 14% of the overall market.  
 
 
 
Looking at ADP's numbers (the largest competitor of Paychex...who actually focuses on large clients), they are almost identical to the Paychex numbers!  
 
 
 
The point is, the average size client that Paychex works with does and will always mirror the average size of all US businesses. That is whaat happens when you are one of the two larget payroll providers in the market.  
 
 
 
I think if you are going to put info out there, you should include all the facts so that you do not mislead your readers.

Yes, I agree that the Paychex clients mirror the US business market.  
 
The census data is interesting-- but if you add it up, 88% of the firms only employ 39% of the employees (the largest 12% employee 61% of employees). 
 
My point in writing the blog was that the top 12% (100 or more employees) have more demanding needs, which happens to be the market that we cater to...
