## 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. [8](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [9](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [10](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [11](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

### A Fixed List Versus Custom-Built Coverage

Heffernan's small-business division names a wide industry range and adds a further option:

Heffernan's small-business division says it serves sole proprietors through fast-growing companies across industries including construction, food, health care, hospitality, nonprofits, real estate, technology, transportation, and vintners and growers, and will custom-design a package for industries not listed. [7](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; not exclusively E&O-specific, but describes the buyer base for the page listing this coverage..)

Alliance Risk instead names a fixed set of professions it targets, including consultants and advisory firms, accountants and tax professionals, and financial planners and investment advisors, without describing a custom-build option for industries outside that list. [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance")

### How Much Detail Each Page Gives on Coverage

Heffernan's page describes errors and omissions coverage in one general sentence: protection against claims that a problem with the company's product or service caused a client financial loss. Alliance Risk's page goes further, itemizing specific covered scenarios like breach of contract and misrepresentation alongside named exclusions such as bodily injury, fraud and cyber incidents. [7](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance")

### How You Start the Process

Heffernan directs buyers to contact its small-business division directly to request a quote and build a package. Alliance Risk's reviewed page offers a generic "Get a quote" request without describing a dedicated division or custom-build process. [7](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance")

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

- Ask Heffernan which carrier it would place your errors and omissions coverage with, since its page names none. [7](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")
- Ask Alliance Risk the same question, since its page also names no carrier. [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance")
- Get actual limit and premium figures from both, since neither publishes them for this line. [7](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance")
- If your industry isn't on Heffernan's list, ask what information it needs to custom-design a package for you. [7](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")

## Offering Details

| Criteria | Alliance Risk Professional Liability Insurance | Heffernan Professional Errors and Omissions Brokerage |
| --- | --- | --- |
| Role in This Line | Alliance Risk places professional liability (errors and omissions, or E&O) coverage as a broker, saying it backs placements with risk-specific underwriting input and carrier partnerships rather than underwriting the policy itself.

[7](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; no dedicated professional-E&O product page was found..) |
| Issuing Insurer | The reviewed professional liability page does not name the insurer that would issue a policy; it refers generally to 'strong carrier partnerships' without identifying a specific carrier. [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") (Evidence: Not publicly disclosed; scope: Professional liability product page as read on 2026-09-23..) | Not described in the reviewed sources. |

| Coverage Features | Alliance Risk lists negligent acts or omissions, breach of contract, misrepresentation, and missed deadlines as typically covered, and says bodily injury or property damage, intentional wrongdoing or fraud, employment disputes, cyber incidents, and prior known claims are excluded and belong to other lines such as general liability, EPLI or cyber liability. [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability product page; coverage and exclusions described in general terms, subject to the policy as issued..) | 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.

| Limits and Retentions | The reviewed professional liability page gives cost ranges by firm size (for example, solo practitioners at $500-$3,000 a year up to mid-sized to large firms at $10,000-$50,000-plus) but does not publish specific coverage limits, retentions or deductible amounts for this line. [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") (Evidence: Not found in reviewed sources; scope: Professional liability product page as read on 2026-09-23; cost figures are illustrative premium estimates, not published limits..) | The reviewed page does not publish limits, retentions, or premium ranges for errors and omissions coverage. [7](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 | Alliance Risk describes its approach to professional liability as including industry-specific risk reviews, claims-trend analysis, customized policy language, review of client contracts to limit personal exposure, and expertise structuring claims-made policies including tail coverage, prior acts and retroactive dates. [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability product page, Our Approach to Professional Liability and The Alliance Risk Difference sections..) | Not described in the reviewed sources. |
| How to Apply | The professional liability page's only application route is a generic 'Get a quote' request; it does not list the specific submission information Alliance Risk asks for on this line, unlike its D&O, EPLI and fiduciary product pages. [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") (Evidence: Not found in reviewed sources; scope: Professional liability product page as read on 2026-09-23..) | 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.

| Claims Support | Alliance Risk says professional liability clients get access to a legal network and claims experts who understand the client's industry, providing a defense strategy if a claim arises. [3](https://joinalliancerisk.com/professional-liability-business-insurance/ "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability product page, The Alliance Risk Difference section..) | Not described in the reviewed sources. |
