Professional Liability (E&O) Insurance
Errors and Omissions (E&O) protection for advice-based professionals, consultants, IT firms, and medical clinics.

What is Professional Liability (E&O) Insurance?
Errors and Omissions (E&O) or Professional Liability Insurance is a specialized coverage designed for business owners who provide professional advice, specialized designs, custom code, or consulting services. Standard general liability (CGL) only covers physical accidents like slips and falls. E&O is designed to cover purely financial losses that clients suffer due to your mistakes, oversight, missed deadlines, or failure to deliver promised professional results.
What Typically Covers
- Allegations of negligence, errors, omissions, or professional oversight.
- Financial losses suffered by your clients due to your work (e.g., custom code crash, faulty financial audit).
- Breach of contract claims arising from failed professional delivery.
- Full cost of legal defense fees, settlements, or damages awarded by a court.
Key Exclusions to Note
- Intentional fraud, misrepresentation, or criminal acts.
- Physical injury or physical property damage (these belong under CGL).
- Cyber breaches or data theft (requires Cyber Liability).
- Warranties or commercial guarantees of business success.
Active Claim Example
“A software consulting firm is hired to develop a custom retail checkout system. Due to an overlooked bug in the code, the online store crashes during Black Friday weekend, causing the client to lose $180,000 in retail revenue.”

Professional Liability (E&O) Insurance FAQs
- Who needs Errors & Omissions (E&O) insurance?
- Any business that bills for advice or service: IT developers, engineers, architects, management consultants, accountants, bookkeepers, and real estate agents.
- How is Professional Liability different from CGL?
- CGL covers physical damage (e.g., you spill coffee on a client's laptop). E&O covers economic damage (e.g., you give a tax recommendation that costs a client $50,000 in government penalties).
- Is E&O on a claims-made basis?
- Yes. Virtually all E&O policies are 'Claims-Made' meaning the policy must be active both when the error occurred AND when the claim is officially reported to the insurer.
