When comparing Harper and Heffernan Insurance Brokers, the more specific product menu can make fit easier to judge before you request a quote.

### Reviewing Exclusions

Harper says it reads a policy's exclusions line by line before a client buys, because two E&O policies with the same limit can respond differently to the same claim. [1](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") Heffernan's page does not describe a comparable exclusions review; it summarizes coverage in one sentence, as protecting against claims that a product or service problem caused a client's financial loss.

### Who Each Brokerage Names as a Fit

Harper targets consultants, agencies, tech firms and licensed professionals whose work product is advice, design or a decision, distinguishing the line from general liability in its FAQ. [1](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") Heffernan instead says its small-business division serves sole proprietors through fast-growing companies across construction, food, health care, hospitality, nonprofits, real estate, technology, transportation, and vintners and growers.

- Harper says it checks exclusions line by line before you buy; ask to see that comparison for your specific policy. [1](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")
- Heffernan's page groups E&O with other small-business coverages rather than giving it a dedicated form; ask whether your submission gets profession-specific underwriting. [4](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")
- Heffernan's reviewed page names no carrier for the E&O it shops, and Harper's pages name none either; ask both directly. [4](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") [1](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")
