[1](https://www.embroker.com/coverage/professional-liability-insurance/ "Professional Liability Insurance Coverage & Quotes") [2](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") ## What Are the Key Differences Between Embroker and USI Insurance Services Professional Liability (E&O) Insurance? ### Whether an Insurer Is Named Embroker's professional liability page describes coverage, exclusions and deductible structure without naming a carrier. [1](https://www.embroker.com/coverage/professional-liability-insurance/ "Professional Liability Insurance Coverage & Quotes") USI's page for its CPA-focused program instead names one directly: USI's own page states that the AICPA Professional Liability Program is "underwritten by CNA," naming the carrier for that specific program. USI's general Business Services E&O placements do not name an insurer. [2](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") (Evidence: Company-reported; scope: Direct quote from the AICPA program page; CNA underwrites only this named program, not USI's other professional-liability placements..) ### Who Each Targets Embroker markets broadly to businesses giving professional advice or services for a fee, naming accountants, bookkeepers, consultants, real estate agents, home inspectors, and IT and healthcare professionals. [1](https://www.embroker.com/coverage/professional-liability-insurance/ "Professional Liability Insurance Coverage & Quotes") USI's named program instead targets sole practitioners and regional CPA firms specifically, a niche it says it has served since 1967; its separate Business Services practice brokers E&O more broadly for other business types. [2](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") [4](https://www.usi.com/property-casualty/business-services/ "Business Services") ### Extra Services Included USI says CPA firms enrolled in its AICPA program get supportive claims handling and exclusive access to risk-management resources, including engagement-letter templates. [2](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") Embroker's page describes no comparable risk-management service; instead it documents deductible choice, letting a buyer select an aggregate deductible or a first-dollar-defense option. [1](https://www.embroker.com/coverage/professional-liability-insurance/ "Professional Liability Insurance Coverage & Quotes") ## What Should You Confirm in Embroker and USI Insurance Services Professional Liability (E&O) Insurance Quotes? - If you're a CPA, confirm whether USI's AICPA program or its general Business Services practice would place your coverage, since only the AICPA program names an insurer. [2](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") - Get the limit and retention on your quote from each; neither publishes figures publicly. [1](https://www.embroker.com/coverage/professional-liability-insurance/ "Professional Liability Insurance Coverage & Quotes") [2](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") - Ask USI whether its engagement-letter templates and claims support extend to firms outside the CPA-specific AICPA program. [4](https://www.usi.com/property-casualty/business-services/ "Business Services") - Ask Embroker whether the aggregate or first-dollar-defense deductible structure is available for accounting firms specifically, or only for other professions it lists.

[2](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") (Evidence: Company-reported; scope: Program page description; actual insuring agreements, exclusions and conditions are set by the issued CNA policy form..) | | Role in This Line | Embroker sells professional liability, also called errors and omissions insurance, as a standalone product for professional-services businesses, separate from its lawyers professional liability program and its bundled technology E&O/cyber product. [1](https://www.embroker.com/coverage/professional-liability-insurance/ "Professional Liability Insurance Coverage & Quotes") (Evidence: Company-reported; scope: Product-page description; not a statement about the issuing insurer..) | For CPA firms, USI runs the AICPA Professional Liability Program through its USI Affinity division as the endorsed producer, rather than underwriting the policy itself. USI's general Business Services practice separately brokers errors and omissions/professional liability coverage for other business types.
