## What Is Professional Errors and Omissions (E&O) Insurance?

Professional errors and omissions (E&O) insurance, also called professional liability insurance, addresses claims that professional services or advice caused a client financial loss. What's covered depends on the services actually scheduled in the policy, not the product label alone. [10](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [11](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [12](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [13](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

## Key Differences in Professional Liability (E&O) Insurance

### Two Different Accounting-Focused Products

Relm describes a distinct Accountants Errors and Omissions product, separate from its general E&O line, covering misconduct accusations, financial misstatements, miscalculations and late filings:

Relm describes a distinct Accountants Errors and Omissions product covering misconduct accusations, financial misstatements, miscalculations, late filings, and in some cases breach of contract, including legal defense costs, settlements and damages. [3](https://relminsurance.com/lines-of-business/professional-lines-and-errors-and-omissions-insurance/ "Professional Lines and Errors and Omissions Insurance") (Evidence: Company-reported; scope: Professional Lines page 'Accountants Errors and Omissions' section; a related but separate product from Relm's general E&O line..)

USI's most detailed E&O offering is the AICPA Professional Liability Program, run through its USI Affinity division specifically for CPA firms, which it has provided since 1994. [7](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity")

### Who Underwrites the Policy

Relm's page does not name a specific issuing insurer for its Accountants E&O product. [3](https://relminsurance.com/lines-of-business/professional-lines-and-errors-and-omissions-insurance/ "Professional Lines and Errors and Omissions Insurance") USI's page names CNA as the underwriter of the AICPA program specifically, though its general Business Services practice, which brokers E&O for other business types, does not name an insurer. [7](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity")

### Who Each Company Targets

Relm's accounting-focused product sits inside a broader family of niche E&O lines that also cover consultants, financial institutions, lawyers, lenders and media. [3](https://relminsurance.com/lines-of-business/professional-lines-and-errors-and-omissions-insurance/ "Professional Lines and Errors and Omissions Insurance") USI's page targets sole practitioners and regional CPA firms specifically through the AICPA program, and has offered CPA coverage since 1967. [7](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity")

## What to Confirm in Professional Liability (E&O) Insurance Quotes

- If you're a CPA firm, ask both companies to confirm which named insurer would issue your policy. [3](https://relminsurance.com/lines-of-business/professional-lines-and-errors-and-omissions-insurance/ "Professional Lines and Errors and Omissions Insurance") [7](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity")
- Ask Relm whether its Accountants E&O or a different niche line fits your specific accounting role. [3](https://relminsurance.com/lines-of-business/professional-lines-and-errors-and-omissions-insurance/ "Professional Lines and Errors and Omissions Insurance")
- Ask USI what risk-management resources, such as engagement-letter templates, come with the AICPA program. [7](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity")
- Neither company's reviewed page publishes limits or retentions for these products; ask both for specific figures. [3](https://relminsurance.com/lines-of-business/professional-lines-and-errors-and-omissions-insurance/ "Professional Lines and Errors and Omissions Insurance") [7](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity")
