What Is Professional Liability Insurance Coverage?

Professional liability insurance protects businesses when employees make mistakes in the professional services they’ve provided to customers or clients. This coverage is also known as errors and omissions insurance (E&O). Even if you’re an expert in your business, mistakes happen. And if your client or customer thinks a mistake in your professional services caused a financial loss, they can sue you.

Why Is Professional Liability Insurance Important?

If your business offers professional services and you don't have professional liability coverage, you can be held liable if a customer believes you made a mistake. Even if it didn’t cause them financial loss, you can still get sued. Small business owners should consider having professional liability coverage because it protects businesses when they need it most. You should especially consider having this coverage if you:
  • Provide professional services
  • Offer advice to clients
  • Are required to have complete coverage

What Does Professional Liability Insurance Cover?

Professional liability insurance for small businesses can help protect against claims of:
If the professional services that you or your company provided result in damage or injury to a client. For example, your accounting firm makes a clerical error that costs your client thousands of dollars.
If a client claims that false or misleading information convinced them into a contract agreement with you or your company, which lead to damages to the client. For example, your bienes raíces firm recently sold a townhouse to a couple that was planning on starting a daycare. However, when the couple moved in, the townhouse association informed them they couldn’t use the property for a business. The new owners decide to sue you for negligence.
If a customer claims that you provided advice that caused them damage. For example, a client sues your florist shop for errors in the services you provided after you failed to deliver flowers on time for their wedding.
If someone accuses you or your business of libel or slander, whether it’s true or not. For example, a competitor claims that your new advertisements are slandering their business and sue you for damages.
If someone claims you or your business used their copyrighted work without their permission and they sue you for copyright infringement. For example, a sound engineer sues your company for using one of their sounds without their permission in one of your new advertisements.
Professional liability insurance can help cover your defense costs if a client sues you for mistakes in the professional services you provided them. Defense costs include attorney fees and other court-related expenses.
Even if you didn’t do anything wrong and believe you’ve made no mistakes, your client can still sue your business. Without coverage, you’ll have to pay expensive legal defense costs out of pocket.

Who Needs Professional Liability Insurance Coverage?

Professional liability insurance is an important coverage that business owners who provide a service to a client or customer should have. You’ll want to get professional liability insurance coverage if you:

How Does Professional Liability Insurance Work?

Many insurance companies write a professional liability insurance policy on a claims-made basis with a retroactive date and extended reporting period.
The retroactive date means you’re covered for incidents that happen on or after a specified date in your policy.
The extended reporting period helps cover claims filed within a certain time after your policy expires. This is generally a 30- to 60-day period, but you can extend this period to a year or more for an additional cost.
Your insurance company only covers claims against your business during your policy period within the extended reporting period. And the claim must be from a covered error or omission that happened after your policy’s retroactive date. It can help cover:
  • Damages
  • Legal defense costs
  • Disciplinary proceedings
  • Loss of earnings
  • Subpoena assistance
Some policies can also be written on an occurrence policy. This means there will be coverage for losses that happen during your policy period, even if the claim gets reported after your policy expires.

Since the claim was reported during the policy period and the loss occurred after the retroactive date, it would be eligible for coverage under a claims-made policy.
If a claim is brought after the policy’s expiration, it can get coverage if it’s reported within the extended reporting period.

Professional Liability Insurance FAQ

The main difference between general liability and professional liability is in the types of risks they cover. General liability insurance covers physical risks, such as bodily injuries and property damage. Professional liability insurance covers more abstract risks, such as errors and omissions in the services your business provides. To make sure your business is fully protected, it’s a good idea to carry both types of insurance.
Yes, professional liability insurance coverage can help protect your business even if the claim against your business is determined to be baseless.
Professional liability insurance provides coverage for claims of negligence in a lawsuit against you. Even if you didn’t do anything wrong and believe you’ve made no mistakes, a client can still sue your business.
Yes, errors and omissions insurance is the same type of coverage as professional liability insurance. E&O insurance helps protect you and your company if a third party claims that you or your business made a mistake in the professional services provided. Just like professional liability insurance, E&O insurance coverage can help cover the costs if a customer files a claim against your small business.
Every small business owner aims to run their business perfectly, but we know that mistakes can happen when we least expect it. If a mistake does happen and it harms your client, they can sue your business.
For example, if one of your analysts at your accounting firm gives a client advice based on outdated data and it results in the client losing thousands of dollars. Your client could then sue your business for negligent misrepresentation because of your employee’s mistake. With professional liability insurance, you’ll be protected from the costly claims resulting from this lawsuit including settlements and legal fees.
A certificate of liability insurance (COI) is a form that provides proof of professional liability insurance coverage for your business. This form summarizes the benefits and limits of your liability insurance policy. You’ll get a certificate of insurance (COI) automatically as proof of insurance when you get your policy. If a company requires another copy of your certificate, you have two different ways to obtain one:
  1. Request a certificate of general insurance through your agent.
  2. Visit our online portal, Mi Cuenta, to request certificates of insurance. We process most requests instantly.
Professional liability insurance doesn’t cover all types of liability claims, like bodily injuries. For example, let's say someone sues your business after a slip and fall in your store. Your professional liability insurance coverage won't help. Instead, you'll need general liability insurance coverage to cover bodily injuries and property damage claims.
