## 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. [12](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [13](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [14](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [15](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

### Who Places the Business

At-Bay distributes MPL through its own disclosed producer, At-Bay Insurance Services LLC, so a buyer's path runs through a submitting agent rather than a direct purchase. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [4](https://www.at-bay.com/licenses/ "Licenses") Coverdash arranges professional liability as a broker under its own standard brokerage terms, placing coverage with a carrier while the buyer interacts with Coverdash directly. [9](https://www.coverdash.com/terms "Terms And Conditions") [10](https://www.coverdash.com/coverage/professional-liability "Professional Liability Insurance")

### How the Buying Process Differs

At-Bay's workflow runs through email submissions or its Broker Platform, described as creating a quote, customizing it, and binding the policy. [6](https://www.at-bay.com/brokers/platform/ "Broker Platform") Coverdash describes a fully digital, self-serve quote-to-purchase process, with the option to add coverages like general liability or cyber alongside professional liability at the same time.

Coverdash describes a fully digital quote-to-purchase process for professional liability, with the option to add coverages such as general liability or cyber alongside it. [10](https://www.coverdash.com/coverage/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Product-page company information and cross-sell section..)

### Scope of Published Coverage Terms

At-Bay lists specific insuring-agreement features for MPL, including a duty-to-defend contract, personal-injury coverage, and an 80/20 hammer clause. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") Coverdash describes coverage in broader categories — negligent advice, mistakes, and missed deadlines — without naming a hammer clause, duty-to-defend structure, or similar policy-level mechanics. [10](https://www.coverdash.com/coverage/professional-liability "Professional Liability Insurance")

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

- Ask whether your business can quote At-Bay's MPL directly or only through a licensed broker. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")
- Neither company names the insurer that would issue your policy; ask both directly. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [10](https://www.coverdash.com/coverage/professional-liability "Professional Liability Insurance")
- Confirm whether Coverdash's professional liability policy includes a duty-to-defend provision like At-Bay's advertised structure. [10](https://www.coverdash.com/coverage/professional-liability "Professional Liability Insurance")
- Ask At-Bay for its published $5 million limit ceiling and applicable state restrictions. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")
- Ask Coverdash for specific limit, retention, or deductible figures, since its page does not publish them. [10](https://www.coverdash.com/coverage/professional-liability "Professional Liability Insurance")

## Offering Details

| Criteria | At-Bay Miscellaneous Professional Liability (MPL) Insurance | Coverdash Professional Liability (E&O) Insurance |
| --- | --- | --- |
| Role in This Line | At-Bay markets MPL as one of its own named insurance products, sold through its disclosed producer, At-Bay Insurance Services LLC, with the product page directed at "properly licensed insurance professionals" submitting business rather than at direct retail buyers. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [4](https://www.at-bay.com/licenses/ "Licenses") (Evidence: Company-reported; scope: Current MPL product page and license disclosures; this describes the distribution channel, not who bears the underwriting risk..) | Coverdash arranges professional liability (errors and omissions) coverage as a broker rather than an insurer, placing coverage with a carrier under its standard brokerage terms. [9](https://www.coverdash.com/terms "Terms And Conditions") [10](https://www.coverdash.com/coverage/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: General brokerage terms applied to the professional liability page; not specific to any one carrier or state..) |
| Issuing Insurer | The current MPL product page does not name the insurer that issues the policy. A September 2023 press release named United Specialty Company in connection with MPL, but that historical reference does not establish the current issuing insurer for a new MPL quote. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [5](https://www.at-bay.com/press_releases/at-bay-doubles-mpl/ "At-Bay Doubles Miscellaneous Professional Liability Appetite") (Evidence: Not found in reviewed sources; scope: Reviewed MPL page as of 2026-09-23 and the September 2023 press release; restates the existing provider fact that MPL's current issuer is unresolved, distinct from the August 2023 Cyber/Tech E&O transition to At-Bay Specialty Insurance Company paper..) | The professional liability page does not name the insurer that issues the policy. [10](https://www.coverdash.com/coverage/professional-liability "Professional Liability Insurance") (Evidence: Not publicly disclosed; scope: Reviewed professional liability page as of 2026-09-23; the page describes coverage without naming a specific carrier..) |
| Who It’s For | At-Bay says it provides primary MPL for businesses of all revenue sizes with limits up to $5 million, subject to state restrictions and eligibility requirements detailed in a separate MPL appetite guide. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") (Evidence: Company-reported; scope: Current MPL appetite paragraph; the linked appetite guide's specific eligibility requirements were not independently opened for this record..) | Coverdash markets professional liability to any small business, startup or e-commerce seller that gives advice, provides a service or delivers work for clients, citing examples including architects, dentists, doctors and real estate agencies. [10](https://www.coverdash.com/coverage/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Product-page eligibility description; actual acceptance depends on underwriting and profession-specific appetite..) |
| Coverage Features | At-Bay lists MPL coverage highlights including automatic coverage for acquired subsidiaries, claims-made-and-reported coverage, coverage for independent contractors, disciplinary-proceedings defense, a duty-to-defend contract, personal-injury coverage (including emotional distress), punitive damages where insurable, a professional-services definition written for each insured, and an 80/20 hammer clause. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") (Evidence: Company-reported; scope: Product-page coverage-highlights list; an 80/20 hammer clause is a settlement provision where the insurer pays 80% and the insured pays 20% of costs after the insured declines a recommended settlement. The issued policy and declarations control actual wording, limits and exclusions..) | Coverdash describes professional liability as covering claims that a client's financial harm came from the business's negligent advice or service, mistakes made by the business or an employee, or a missed deadline or undelivered work, and pays legal defense costs even for a baseless claim. [10](https://www.coverdash.com/coverage/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Product-page coverage cards; the issued policy and declarations control actual wording, limits, exclusions and whether the policy is claims-made..)<br><br>Coverdash's coverage hub lists this general professional liability product separately from Tech E&O (for technology companies) and Lawyers Professional Liability, so a technology or legal business would typically be pointed to the more specific product instead. [11](https://www.coverdash.com/coverage "Coverage Hub") (Evidence: Company-reported; scope: Coverage hub category structure; does not establish which product a given underwriter would actually issue..) |
| Limits and Retentions | At-Bay publishes an MPL limit ceiling of up to $5 million, with state restrictions that are not detailed on the product page itself. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") (Evidence: Company-reported; scope: Current appetite paragraph; this is an advertised ceiling, not a guaranteed available limit for any specific applicant..) | The professional liability page does not publish specific limit, retention or deductible amounts. [10](https://www.coverdash.com/coverage/professional-liability "Professional Liability Insurance") (Evidence: Not publicly disclosed; scope: Reviewed professional liability page as of 2026-09-23; figures are quote-specific and not shown on the public product page..) |
| How to Apply | At-Bay directs MPL submissions to underwriting by email or through automatic quotes on its Broker Platform, which At-Bay describes as a workflow of creating a quote, customizing limits and retentions, and binding the policy. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [6](https://www.at-bay.com/brokers/platform/ "Broker Platform") (Evidence: Company-reported; scope: Current submission instructions and the general broker-platform workflow description; MPL-specific automation details were not separately confirmed..) | Coverdash describes a fully digital quote-to-purchase process for professional liability, with the option to add coverages such as general liability or cyber alongside it.
