The Small Business Guide To Professional Liability (Errors & Omissions) Insurance

Professional liability insurance — also known as errors and omissions (E&O) insurance, indemnity insurance, or malpractice insurance — protects businesses from claims that they made a mistake or provided inadequate advice.

If your business offers professional services, general liability insurance typically won’t cover these claims. Professional liability insurance helps cover legal defense costs, settlements, and judgments related to negligence, misrepresentation, or errors in your work.

This guide explains how professional liability insurance works, what it covers, and how to choose the right policy for your business.

What Is Professional Liability (Errors & Omissions) Insurance?

Professional liability insurance protects businesses from the cost of claims related to mistakes, negligence, or failure to deliver services as expected.

It typically covers:

• Negligence (e.g., errors in judgment or failure to meet professional standards)
• Misrepresentation
• Errors and omissions in services provided
• Legal defense costs, settlements, and judgments

For example, a claim could arise from incorrect advice, missed deadlines, or data loss that impacts a client.

How Does Professional Liability Insurance Work?

Professional liability insurance covers legal and financial costs if your business is accused of negligence, errors, or failure to deliver services as expected.

If a claim is filed, the policy may help cover:

• Legal defense costs (attorneys, court fees)
• Settlements or judgments
• Other related claim expenses, up to your policy limits

Coverage depends on your policy terms and whether the claim falls within covered risks.

Types Of Professional Liability (Errors & Omissions) Insurance

There are two main policy types:

• Claims-made: Covers claims filed while the policy is active, as long as the incident occurred after the policy’s retroactive date. If coverage lapses, claims are typically not covered unless you have extended reporting (“tail”) coverage.
• Occurrence-based: Covers incidents that occurred while the policy was active, even if the claim is filed later after the policy has ended.

Note: Claims-made policies are more common for professional liability insurance.

Additional Types Of Business Insurance

Professional liability insurance covers service-related risks, but most businesses need additional coverage for broader protection.

Common policies to consider include:

What Does Professional Liability Insurance Cover?

Professional liability insurance covers claims that your business made a mistake, provided inadequate services, or failed to meet professional standards.

Coverage typically includes:

• Negligence and errors: Mistakes, missed deadlines, or failure to meet industry standards
• Errors and omissions: Incomplete work, oversights, or failure to deliver services as expected
• Misrepresentation: Incorrect or misleading advice or services
• Legal defense costs: Attorney fees, court costs, and related expenses
• Settlements and judgments: Payments if your business is found liable
• Personal and advertising injury: Claims such as defamation, libel, or slander (if included in the policy)
• Intellectual property claims: Limited coverage for issues like copyright infringement (varies by policy)

These claims typically involve financial harm rather than physical injury or property damage, which is why they are not usually covered under general liability insurance.

What Professional Liability (Errors & Omissions) Insurance Doesn’t Cover

Professional liability insurance covers service-related risks, but it does not apply to all types of business claims. Coverage varies by policy, but common exclusions include:

• Intentional or illegal acts: Claims involving fraud, criminal activity, or deliberate wrongdoing
• Employee injuries: Covered under workers’ compensation insurance
• Bodily injury or property damage: Typically covered under general liability insurance, unless tied directly to professional services (e.g., malpractice)
• Employment-related claims: Issues like discrimination or wrongful termination, which are usually covered by employment practices liability insurance (EPLI)
• Cyber incidents: Data breaches and cyberattacks, which require cyber liability insurance
• Contractual guarantees: Claims based on guaranteed results or performance beyond standard professional duties (varies by policy)

Who Needs Professional Liability (E&O) Insurance?

Professional liability insurance is recommended for businesses that provide services or professional advice.

It’s commonly used by:

• Consultants, freelancers, and agencies
• Accountants, financial advisors, and real estate professionals
• IT professionals, designers, and marketers
• Healthcare providers and legal professionals

Some professions — such as doctors and lawyers — may be required to carry professional liability (often called malpractice insurance) to meet state licensing or regulatory requirements.

When to Consider Coverage

You may need professional liability insurance if your business:

• Provides advice or professional recommendations
• Delivers services where mistakes could cause financial loss
• Handles client data, projects, or deliverables
• Could face claims of errors, omissions, or missed deadlines

If these risks apply to your business, professional liability coverage can help protect against potential claims.

How Much Does Professional Liability (Errors & Omissions) Insurance Cost?

Professional liability insurance costs vary based on your business’s risk profile, industry, and coverage needs.

As a general benchmark, many small businesses pay between $500 and $1,000 per year, though premiums can be lower or significantly higher depending on the level of risk.

Key factors that affect cost include:

• Industry and services provided: Higher-risk professions (e.g., legal, medical, financial) typically pay more
• Business size: More clients, employees, or projects can increase exposure
• Coverage limits: Higher limits lead to higher premiums
• Claims history: Past claims can increase rates
• Location: State laws and litigation risk can impact pricing

Ways to Manage Costs

• Adjust your deductible: Higher deductibles can lower premiums but increase out-of-pocket costs if a claim occurs
• Bundle policies: Combining coverage (e.g., with general liability) may reduce overall costs
• Maintain strong risk controls: Clear contracts, documentation, and internal processes may help reduce claims risk
