What Is Professional Errors and Omissions (E&O) Insurance?
Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. 10,11,12,13
Key Differences in Professional Liability (E&O) Insurance
CPA-specific program versus broader quote examples
USI’s AICPA Professional Liability Program is aimed at sole practitioners and regional CPA firms. Simply Business lists consultants, IT professionals, real-estate agents and bookkeepers among E&O examples. A CPA firm should compare the program’s eligibility and terms with any marketplace quote rather than assuming a general professional-liability offer is equivalent. 7 3
USI identifies CNA for the AICPA program
USI states that CNA underwrites the AICPA program. Its general business E&O placements do not name an insurer, and Simply Business’s insurer depends on the particular panel quote. Confirm which USI route and which issuer apply to your firm before comparing carrier terms. 7 2
The USI program adds CPA-focused resources
USI says enrolled firms receive claims support and access to risk resources such as engagement-letter templates. Simply Business’s E&O materials focus on online quote comparison and possible covered legal costs. If claims guidance or practice tools matter, ask what is included with the precise Simply Business placement. 7 3
