If you sell advice, expertise or professional services, such as management consulting, marketing, IT, software development, HR, design, coaching or bookkeeping, your biggest liability risk usually isn't someone slipping in your office. It's a client claiming your work cost them money. That's what professional liability insurance, also called errors and omissions (E&O), is designed to address.
What E&O covers
E&O policies typically cover claims alleging financial loss caused by:
- Errors, mistakes or oversights in your work
- Negligence or failure to perform professional services
- Missed deadlines that cause client losses
- Misrepresentation or inaccurate advice
- Breach of duty related to your professional services
A key benefit is defense costs. Even if the claim has no merit, defending a lawsuit can be expensive. Many E&O policies include defense costs within the limit (so-called defense-within-limits or "eroding" limits), which means legal fees reduce the amount available for a settlement. Ask about this when choosing limits.
What E&O usually doesn't cover
- Bodily injury and property damage. That's general liability.
- Intentional wrongdoing, fraud and criminal acts.
- Contractual liability you assumed beyond your normal legal liability (for example, broad indemnity agreements), subject to policy wording.
- Guarantees of results or fee disputes, in many forms.
- Data breaches and cyber incidents, unless the policy includes cyber coverage. See our cyber insurance guide.
- Employment claims by your own employees, which call for employment practices liability (EPLI).
The U.S. Small Business Administration describes professional liability among the core types of business insurance: SBA – Get business insurance.
E&O vs. general liability
| General liability | Professional liability (E&O) | |
|---|---|---|
| Covers | Bodily injury, property damage, personal and advertising injury | Financial loss from professional services |
| Example | Client trips over your laptop cord at their office | Client says your software recommendation caused a costly outage |
| Trigger | Usually occurrence | Usually claims-made |
Many consultants need both. A business owner's policy (BOP) bundles general liability with property, but usually excludes professional services. See our small business insurance by industry guide.
Claims-made coverage: the most important concept
Most E&O policies are written on a claims-made basis. That means:
- The claim must be made during the policy period (or an extended reporting period) to be covered.
- The work must have been performed after the retroactive date. The retro date is usually the date you first bought continuous E&O coverage.
Why it matters:
- Don't let coverage lapse. If you cancel and a client sues later about past work, you may have no coverage.
- Keep your retro date when switching insurers. A new insurer should honor your existing retroactive date ("prior acts coverage"). If the new policy resets the retro date, work you performed before that date isn't covered.
- Report potential claims promptly. Most policies require you to report claims, and often circumstances that could lead to claims, during the policy period.
Tail coverage (extended reporting period)
If you retire, close your business or switch to a policy without prior acts coverage, an extended reporting period (ERP), or "tail," lets you report claims made after the policy ends for work done while it was in force. Tails are purchased for a set period, sometimes with options for multiple years, and must usually be elected within a short window after cancellation. Plan for it before you close a practice.
Client contract requirements
Larger clients, government agencies and staffing firms often require consultants to carry E&O at specified limits, and sometimes general liability, cyber and workers' compensation. Before signing:
- Check required limits (per claim and aggregate).
- Look for requirements to keep coverage in force for a period after the project ends, which works with claims-made policies.
- Review indemnification clauses. Broad indemnity may obligate you beyond what insurance covers.
- Note any additional insured request. Additional insured status is common on general liability but less common on E&O; ask your broker how to respond.

Licensed professions
Some professions are subject to licensing board rules or state requirements regarding insurance, such as certain financial, legal, health care, and design professionals. If you're licensed, check your board's rules. Insurance agents themselves carry E&O; you can confirm a California agent's license on the California Department of Insurance license lookup.
Choosing limits and deductibles
Factors to consider:
- The size of the projects and the potential financial harm from a mistake
- Client contract requirements
- Whether defense costs erode the limit
- Your industry's claim patterns
- Deductible or retention you can afford
Reducing professional liability risk
- Use written contracts with clear scope, deliverables and limitation-of-liability clauses reviewed by an attorney.
- Document changes in scope, client approvals and key communications.
- Avoid guarantees of specific results.
- Manage expectations with realistic timelines.
- Stay in your lane. Work outside your expertise can be excluded and is riskier.
- Protect data with good cybersecurity practices.

Frequently asked questions
What is errors and omissions insurance?
Errors and omissions (E&O), or professional liability, insurance covers claims that your professional services caused a client financial loss, including defense costs, subject to policy terms.
What does claims-made mean?
A claims-made policy covers claims made during the policy period for work performed after the retroactive date. Lapses can leave past work uncovered.
What is tail coverage?
An extended reporting period that lets you report claims after a claims-made policy ends, for work done while it was in force.
Does general liability cover professional mistakes?
Generally no. General liability covers bodily injury and property damage. Professional mistakes that cause financial loss are covered by E&O.
Do I need E&O as a freelancer?
It's not usually legally required, but many clients require it, and it can protect you against costly claims about your work.
