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

USI's AICPA Professional Liability Program is underwritten by CNA for CPA firms specifically, while Kinro brokers professional liability/E&O generally and matches a submission to a carrier by appetite. [2](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") [1](https://kinro.com/products/professional-liability "Professional Liability / E&O")

## What Are the Key Differences Between Kinro and USI Insurance Services Professional Liability (E&O) Insurance?

### A Named Insurer for One Program

USI's page names a carrier for its AICPA-endorsed program specifically. [2](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") Kinro's page, by contrast, describes matching a submission to a carrier by appetite without naming one, since the fit depends on the specific operation. [1](https://kinro.com/products/professional-liability "Professional Liability / E&O")

### A CPA-Specific Program Versus a General Submission

USI's page describes a program built for one profession over decades:

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. [2](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") (Evidence: Company-reported; scope: Program page description..)

Kinro's page instead names broad fit categories — consultants, agencies, tech services and professional firms — without a profession-specific, decades-old program comparable to USI's AICPA relationship. [1](https://kinro.com/products/professional-liability "Professional Liability / E&O")

### Services Bundled With the Policy

USI's page says AICPA program enrollees get supportive claims handling and exclusive access to risk-management resources, including engagement-letter templates, alongside the coverage. [2](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") Kinro's reviewed page does not describe a comparable claims-handling or risk-management service bundled with its submissions; it focuses on the intake used to route the business to a carrier. [1](https://kinro.com/products/professional-liability "Professional Liability / E&O")

## What Should You Confirm in Kinro and USI Insurance Services Professional Liability (E&O) Insurance Quotes?

- If you're a CPA firm, ask USI whether you'd be placed in the CNA-underwritten AICPA program or a different market. [2](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity")
- Ask Kinro which carrier it would route your submission to if you don't fit the AICPA program's CPA focus. [1](https://kinro.com/products/professional-liability "Professional Liability / E&O")
- Ask USI whether the AICPA program's risk-management resources, like engagement-letter templates, extend to its general Business Services E&O placements. [2](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity")
- Neither page publishes limits or retentions for these placements; get both in writing. [2](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") [1](https://kinro.com/products/professional-liability "Professional Liability / E&O")

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

| Criteria | Kinro Professional Liability / E&O | AICPA Professional Liability Program (USI Affinity) |
| --- | --- | --- |
| Who It’s For | Kinro says this coverage commonly fits consultants, agencies, tech services and professional firms, and typically comes up when clients rely on the business's professional advice or deliverables, or a contract requires E&O or professional liability. [1](https://kinro.com/products/professional-liability "Professional Liability / E&O") (Evidence: Company-reported; scope: Professional Liability / E&O page "Common fit" and "Triggers" sections..) | 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. [2](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 | To quote professional liability/E&O, Kinro collects the services provided, client types, revenue and contract terms, prior claims and retroactive dates, and whether the business handles regulated, technical, financial or operational advice, and often reviews it together with cyber, general liability and D&O coverage. [1](https://kinro.com/products/professional-liability "Professional Liability / E&O") (Evidence: Company-reported; scope: Professional Liability / E&O page "Quote file" and "Reviewed with" sections..) | 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. [2](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..) |
| Coverage Features | Kinro describes professional liability/E&O as addressing claims tied to alleged errors, omissions, missed deadlines or service mistakes, and says it covers defense and claim-handling questions that a general liability policy may not address. [1](https://kinro.com/products/professional-liability "Professional Liability / E&O") (Evidence: Company-reported; scope: Professional Liability / E&O page introduction and "Coverage" section; actual terms depend on the carrier and policy placed..) | 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. [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 | Kinro is a broker: it matches a business to a professional liability/E&O carrier rather than underwriting the policy itself, saying the product "can underwrite differently" by operation and that market fit depends on carrier appetite. [1](https://kinro.com/products/professional-liability "Professional Liability / E&O") (Evidence: Company-reported; scope: Professional Liability / E&O page "Routing" and "Market fit" sections..) | 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. [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") (Evidence: Company-reported; scope: AICPA program page and Business Services practice page..) |
