Kinro vs USI Insurance Services: How Do They Compare for Professional Liability (E&O) Insurance?

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 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

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. ²Company-reported. 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

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 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

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
Ask Kinro which carrier it would route your submission to if you don't fit the AICPA program's CPA focus. ¹
Ask USI whether the AICPA program's risk-management resources, like engagement-letter templates, extend to its general Business Services E&O placements. ²
Neither page publishes limits or retentions for these placements; get both in writing. ² ¹

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. ²Company-reported. 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. ¹Company-reported.
