# Embroker vs USI Insurance Services Professional Liability (E&O) Insurance

USI names CNA as the underwriter of its CPA-focused AICPA program; Embroker's professional liability page names no insurer for its general product.

## Research Scope and Use

Use this comparison to evaluate Embroker and USI Insurance Services for Professional Liability (E&O) Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

USI's AICPA Professional Liability Program page names CNA as the underwriter for that CPA-specific program. Embroker's professional liability page markets to a broader range of service businesses and does not name an issuing insurer.

## 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. [11](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [12](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [13](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [14](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

### Whether an Insurer Is Named

Embroker's professional liability page describes coverage, exclusions and deductible structure without naming a carrier. [4](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. [8](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. [4](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. [8](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") [10](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. [8](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. [4](https://www.embroker.com/coverage/professional-liability-insurance/ "Professional Liability Insurance Coverage & Quotes")

## What to Confirm in 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. [8](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. [4](https://www.embroker.com/coverage/professional-liability-insurance/ "Professional Liability Insurance Coverage & Quotes") [8](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. [10](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. [4](https://www.embroker.com/coverage/professional-liability-insurance/ "Professional Liability Insurance Coverage & Quotes")

## Offering Details

| Criteria | Embroker Professional Liability Insurance | AICPA Professional Liability Program (USI Affinity) |
| --- | --- | --- |
| 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. [4](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. [8](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") [10](https://www.usi.com/property-casualty/business-services/ "Business Services") (Evidence: Company-reported; scope: AICPA program page and Business Services practice page..) |
| Issuing Insurer | Not described in the reviewed sources. | 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. [8](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 It’s For | Embroker markets the policy to anyone who provides professional advice or services for a fee, listing accountants, bookkeepers, consultants, real estate agents, home inspectors, and IT and healthcare professionals as example buyers, while noting lawyers and doctors typically use specialized malpractice coverage instead. [4](https://www.embroker.com/coverage/professional-liability-insurance/ "Professional Liability Insurance Coverage & Quotes") (Evidence: Company-reported; scope: Product-page eligibility and industry-example sections; not a guarantee of coverage for a particular business..) | USI markets the AICPA program to sole practitioners and regional CPA firms. It has offered CPA coverage since 1967 and has been the endorsed AICPA Program provider since 1994. [8](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") (Evidence: Company-reported; scope: Program page description..) |
| Coverage Features | Embroker lists coverage for claims of errors, omissions or negligence, failing to meet expected standards or deadlines, false or misleading statements, breach of contractual obligations, and attorney fees from covered claims. [4](https://www.embroker.com/coverage/professional-liability-insurance/ "Professional Liability Insurance Coverage & Quotes") (Evidence: Company-reported; scope: Product-page What's covered section; the issued policy and declarations control..)<br><br>Embroker says the policy does not cover personal injury or property damage (handled by general liability), cyberattacks and data breaches (some tech E&O policies offer limited cyber coverage, but full protection needs a separate cyber policy), employee injuries, or employee discrimination claims (handled by EPLI). [4](https://www.embroker.com/coverage/professional-liability-insurance/ "Professional Liability Insurance Coverage & Quotes") (Evidence: Company-reported; scope: Product-page What's not included and 'Do I need Professional Liability insurance if I already have General Liability coverage?' sections..) | USI describes the policy as insuring a CPA and their practice against third-party claims that professional services caused financial harm, providing a defense and paying damages for covered claims arising from high-risk situations tied to new clients, changing business plans, or new laws and regulations. [8](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..) |
| Limits and Retentions | Embroker says the policy carries a deductible, that a higher deductible generally lowers the premium, and that buyers can choose an aggregate (once-annually capped) deductible or a first-dollar-defense option that applies the deductible only to damages, not legal costs. [4](https://www.embroker.com/coverage/professional-liability-insurance/ "Professional Liability Insurance Coverage & Quotes") (Evidence: Company-reported; scope: Product-page 'Does it have a deductible?' section; specific dollar limits and deductible amounts are not published and depend on underwriting..) | The AICPA program page does not publish limit, retention or premium figures; it says coverage plans allow a firm to tailor coverage to its risk profile. [8](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") (Evidence: Not publicly disclosed; scope: Page as read on 2026-09-23..) |
| Risk Services | Not described in the reviewed sources. | USI says firms enrolled in the program get supportive claims handling and exclusive access to risk-management resources, including engagement-letter templates, in addition to the coverage itself. [8](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") (Evidence: Company-reported; scope: Program page description..) |
| How to Apply | Embroker offers an online quote for professional liability through its digital platform, describing underwriting factors including business size, industry risk, location and claims history. [4](https://www.embroker.com/coverage/professional-liability-insurance/ "Professional Liability Insurance Coverage & Quotes") (Evidence: Company-reported; scope: Product-page 'Quick quotes' feature and cost-factor list; no quote was requested during this research..) | USI directs CPA firms seeking a quote or renewal to contact USI Affinity, with a dedicated Affinity_APL@usi.com address for the AICPA program specifically. [8](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") (Evidence: Company-reported; scope: Contact instructions on the AICPA program page..) |
