Professional liability & errors and omissions (E&O).

Your general liability pays if a client trips in your office. It pays nothing if your work costs that client money. For anyone paid to advise or deliver a professional service, that second risk is the one that ends businesses, and it has its own policy.

What E&O actually covers

Professional liability, also called errors and omissions, covers claims that your professional work caused a client a financial loss. A mistake, an oversight, missed advice, a deadline you did not hit, a service that did not deliver what was promised. It covers the claim itself, and it covers the legal defense, which is frequently the bigger number even when the claim goes nowhere.

The key word is financial. E&O is not about someone getting physically hurt or something being physically broken. It is about money a client lost because they relied on your work. That is a completely different risk from the one general liability handles, which is exactly why it is a separate policy.

General liability vs. E&O

This is the distinction that trips people up, so here it is plainly:

  • General liability responds to physical harm: a customer slips in your lobby, your equipment damages someone's property.
  • Professional liability (E&O) responds to financial harm from your professional work: your advice, design, filing, or service caused a client a loss.

A service business often needs both, because a general liability policy will look at an E&O claim and correctly say "that is not what I cover." Assuming one protects you from the other is how a business discovers the gap at the worst possible moment.

Who needs it

If people pay you for your judgment or your work product, you are exposed. That includes real estate agents and brokers, accountants and tax preparers, consultants, IT and software firms, designers, architects and engineers, property managers, and many licensed trades. In a lot of these fields it is not optional, a licensing board requires it, or a client will not sign a contract without seeing proof of it.

You do not have to be wrong to get sued. You only have to be blamed. E&O exists for the gap between doing good work and being accused of not doing it.

The date trap nobody explains

E&O is almost always written on a claims-made basis, and this is the part that quietly burns people. A claims-made policy responds based on when the claim is made, not when you did the work: it must be in force when the claim is filed, and the work must have happened on or after the policy's retroactive date. The policy does not have to have existed back when you did the work — the retroactive date is what reaches back to cover it. The practical consequences:

  • If you drop the policy or switch carriers carelessly, claims about your past work can fall through the cracks.
  • When you retire or close, work you did years ago can still generate a claim, so you may need extended reporting, called tail coverage, to stay protected.
  • A new policy with a recent retroactive date may not cover the work you did before it.

None of this is a reason to avoid E&O. It is a reason to set it up correctly and not let it lapse by accident. That is a large part of what I watch for when I place and renew it.

How I work

I place professional liability with multiple carriers, and the goal of a conversation is to match the coverage to the actual risk in your field, not to sell you a generic policy. I will look at what your work exposes you to, what your licensing board or your contracts require, and how your retroactive date and limits line up with the work you have already done. Then I tell you plainly where you stand.

Frequently asked questions

What is professional liability (E&O) insurance?

Professional liability, also called errors and omissions (E&O), covers claims that your professional work, advice, or service caused a client a financial loss, whether through a mistake, an oversight, or a failure to deliver. It also pays the legal defense costs, which are often the larger expense.

What is the difference between general liability and E&O?

General liability covers physical harm, such as bodily injury or property damage to someone else. E&O covers financial harm caused by your professional work. They are different risks, and many service businesses need both because one does not cover the other.

Who needs professional liability insurance?

Anyone paid to advise clients or deliver a professional service: real estate agents and brokers, accountants and tax preparers, consultants, IT and design firms, architects and engineers, property managers, and many licensed trades. It is often required by a licensing board or written into client contracts.

What is claims-made coverage and why does the date matter?

E&O is usually written on a claims-made basis: the policy must be in force when the claim is filed, and the work must have occurred on or after the policy's retroactive date. The policy does not need to have been in force at the time you did the work — the retroactive date is what reaches back to cover it. If you let the policy lapse, past work can become uncovered unless you purchase extended reporting, known as tail coverage.

Is malpractice insurance the same as E&O?

Essentially yes. Malpractice insurance is professional liability for specific fields such as medical or legal practice. It is the same idea under a field-specific name: coverage for claims that your professional work harmed a client.
