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

### Two Catalogue Names Versus One Line Item

Harper markets the identical policy under two catalogue entries, "Professional Liability" and "Errors and Omissions," stating on the E&O page that it is the same policy, just named what a given industry calls it:

Harper markets the identical policy under two catalogue entries, "Professional Liability" and "Errors and Omissions"; the E&O page states it is the same policy, just named what a given industry calls it. [4](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") [5](https://www.harperinsure.com/coverages "What We Cover") (Evidence: Company-reported; scope: Coverage directory listing plus the E&O page's own description; a naming convention Harper states about itself, not a distinction between two products..)

Heffernan instead names errors and omissions once, as one coverage among several its small-business division places for clients. [9](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")

### 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. [3](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. [9](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")

### 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. [3](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. [9](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")

## What to Confirm in Professional Liability (E&O) Insurance Quotes

- Harper says it checks exclusions line by line before you buy; ask to see that comparison for your specific policy. [3](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. [9](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. [9](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")
- Ask Heffernan for a specific limit and premium range for your industry, since its page gives neither, and ask Harper the same.

| Issuing Insurer | The reviewed pages name pricing drivers (services performed, revenue, contract size) but do not name the issuing insurer or publish specific limit, retention or premium figures for this line.

| Who It’s For | Harper targets consultants, agencies, tech firms and licensed professionals whose work product is advice, design or a decision, since general liability doesn't cover a client claiming that work caused a financial loss.

| Coverage Features | Harper describes coverage for errors and omissions in the work itself, negligence allegations about professional judgment, and legal defense costs, with limits it says are matched to the client contracts that require the policy.

The issued policy and its exclusions control actual scope..) | Heffernan describes errors and omissions coverage as protecting against claims for problems with a company's product or service that result in a financial loss to a client. [9](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") (Evidence: Company-reported; scope: Small Business Insurance page as read on 2026-09-23; the page does not list specific exclusions, claims-made versus occurrence form, or endorsements..) |
| Limits and Retentions | Not described in the reviewed sources. | The reviewed page does not publish limits, retentions, or premium ranges for errors and omissions coverage. [9](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") (Evidence: Not publicly disclosed; scope: Small Business Insurance page as read on 2026-09-23..) |
| Risk Services | 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 very differently to the same claim. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page 'We know this' section; a described review practice, not an independently verified outcome..) | Not described in the reviewed sources. |
| How to Apply | You request a quote online or by phone; if a client contract requires E&O, Harper says it places coverage matching that requirement and issues the certificate the same day. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page quote form and FAQ 'My client contract requires E&O. What now?'..) | Heffernan directs small-business buyers to contact the firm's small-business division to request a quote and says it will research and build a custom package for industries not already listed.
