Errors and Omissions (E&O) Insurance
Also called professional liability insurance, E&O protects your business when a client claims your work, advice, or service caused them a financial loss. One mistake, one missed deadline, or one unhappy client can trigger a lawsuit, even if you did nothing wrong. E&O is what defends you.

Quick Answer: Errors and omissions (E&O) insurance, also known as professional liability insurance, covers the financial harm a client suffers because of a mistake, oversight, or piece of bad advice in the professional services your business provides. It pays legal defense, settlements, and judgments for claims of negligence, errors, or failure to deliver. It does not cover bodily injury or property damage, which is general liability. Many client contracts require it.
People make mistakes, and in a service business a single mistake can become a lawsuit. A missed deadline, a typo in a contract, advice that did not work out, or simply a client who believes you fell short, any of these can end in a claim for the money they say they lost. The hard part is that you do not have to actually be at fault to be sued, and defending even a baseless claim can cost tens of thousands of dollars. According to the U.S. Small Business Administration, professional liability is one of the core coverages service businesses should carry. As an independent brokerage, Pro Insurance Group matches your profession to the right E&O policy and makes sure the details that decide whether a claim is paid, like your retroactive date, are set correctly.
What E&O Insurance Covers
Negligence
Claims that your business failed to perform its professional duties to the standard a client reasonably expected.
Errors in Your Work
Mistakes in the services you delivered that caused a client a financial loss, from a flawed design to a calculation error.
Omissions and Failure to Act
Something you should have done but did not, such as a missed filing, a forgotten step, or a deadline that slipped.
Inaccurate Advice
Guidance or recommendations a client relied on that turned out to be wrong and cost them money.
Misrepresentation
Allegations that you misstated what your service would do or failed to meet what was promised.
Defense Costs
Court costs, attorney fees, and settlements, even when the claim is groundless. Defense is often the biggest expense.
What E&O Does Not Cover
E&O is focused on the financial harm of professional mistakes. It is not a catch-all, and these exposures belong on other policies:
- Bodily injury or property damage, which fall under general liability.
- Employee injuries or illness, which fall under workers compensation.
- Data breaches and cyber incidents, which fall under cyber liability.
- Stolen intellectual property, and intentional or illegal acts.
Why the Retroactive Date Matters
E&O is almost always written on a claims-made basis, which works differently from most business insurance and trips up a lot of owners. A claims-made policy responds only when both the work and the claim fall within the right window. Two dates control everything: the retroactive date, which is the earliest point your past work is covered, and the policy period the claim is reported in. If a claim is reported after the policy ends, an extended reporting period, often called tail coverage, can preserve protection for past work.
The practical takeaway is simple. When you switch carriers or let a policy lapse, you can accidentally lose coverage for years of past work if the retroactive date is not carried forward. This is exactly the kind of detail an independent broker watches so a gap never opens up. We make sure your retroactive date and reporting terms protect the work you have already done, not just the work ahead.
Which Businesses Need E&O
Any business that gives advice or delivers a professional service for a fee. Consultants, accountants, financial advisors, real estate agents, insurance agents, attorneys, marketing agencies, architects, and engineers are classic examples, and many of their client contracts require it. See coverage built for your field:
E&O vs General Liability vs D&O
These three coverages get confused constantly, but each answers a different question about what went wrong:
- E&O answers, did your professional work or advice cause a client a financial loss?
- General liability answers, did your business cause someone bodily injury or property damage?
- Directors and officers answers, did a leadership decision harm the organization, its investors, or its members?
A botched client deliverable is E&O. A customer slipping in your office is general liability. A shareholder suit over a bad decision is D&O. Most service businesses need at least E&O and general liability, and we often bundle them in a business owners policy to lower the combined cost.
What E&O Insurance Costs
| Business Profile | Typical Annual Premium |
|---|---|
| Solo consultant or small service firm | $500 to $1,500 |
| IT, tech, or marketing firm | $1,000 to $3,000 |
| Higher-risk or regulated profession | $3,000 and up |
| Larger firm or high coverage limits | Priced individually |
Ranges are illustrative. E&O premium depends on your industry and risk level, your coverage limit, your claims history, and where you operate. Request a quote for a firm number tailored to your profession.

Errors and Omissions Insurance FAQ
What is errors and omissions insurance?
E&O insurance, also called professional liability insurance, covers the financial harm a client suffers because of a mistake, oversight, or piece of bad advice in the professional services your business provides. It pays legal defense, settlements, and judgments on covered claims of negligence, errors, and failure to deliver.
Is E&O the same as professional liability insurance?
Yes. Errors and omissions and professional liability are two names for the same coverage. Some industries favor one term over the other, but both describe insurance that protects you from claims that your professional work or advice cost a client money.
What is the difference between E&O and general liability?
General liability covers physical harm: bodily injury and property damage, like a client tripping in your office. E&O covers financial harm from your professional work, like a costly error in a deliverable or bad advice. They cover different risks, so most service businesses need both.
Do I need E&O if I never make mistakes?
Yes, because you do not have to be at fault to be sued. A client who is simply unhappy with the outcome can still file a claim, and defending even a groundless lawsuit can cost tens of thousands of dollars. E&O pays that defense whether the claim has merit or not.
What is a retroactive date and why does it matter?
E&O is usually claims-made, meaning the retroactive date sets the earliest point your past work is covered. If you switch carriers or let a policy lapse without carrying the retroactive date forward, you can lose coverage for years of completed work. Protecting that date is one of the most important things a broker does for you.
How much does E&O insurance cost?
A solo consultant or small service firm often pays $500 to $1,500 per year, an IT or marketing firm $1,000 to $3,000, and higher-risk or regulated professions more. Cost depends on your industry, coverage limit, claims history, and location. We shop professional liability markets to find the best fit.
