Insurance jargon can be difficult to follow when a policy is called by multiple names. One example is professional liability, also known as errors and omissions, or malpractice insurance. The coverage is the same, but the name may depend on the type of business that the coverage is for. For architects and consultants, this policy is called professional liability. In the real estate and IT sectors, it’s errors and omissions. And, for medical and legal professions, it’s known as malpractice insurance. Like most insurance policies, the cost may vary depending on several factors, such as location and industry. Get free liability insurance quotes with Insureon today. Click the link to get started.

How professional liability insurance protects your business

Businesses that provide professional services typically need professional liability / errors and omissions coverage because those services come with risks. A client could hold your business liable for:

  • Breach of contract
  • Work oversights or errors
  • Providing substandard or incomplete work
  • Missed deadlines

If these professional mistakes result in financial losses for a client, they could sue to recoup expenses. Professional liability / E&O insurance helps cover:

  • Attorney fees
  • Court costs
  • Settlements or judgments

Even if there was nothing wrong with the quality of your work, a difficult or dissatisfied client could sue your business over a perceived problem. In that case, you might win the lawsuit but still have to pay attorney fees and court costs out of pocket. Without professional liability and errors and omissions insurance, a lawsuit could present a major financial difficulty for your business.


Many clients will require your company to carry this policy before they hire you.

The benefits and cost of professional liability insurance

Professional liability insurance helps you market your business as trustworthy and responsible, setting you apart from uninsured competitors. It’s not just good for business – it’s often a must for business.

Many clients will require your company to present a certificate of insurance for this policy before they hire you. If a project doesn't go as planned, they feel assured they can recoup their losses. Review your contract carefully to see if this coverage is a requirement.

Insureon’s professional liability insurance cost report offers details on how much businesses in different industries can expect to pay for this coverage. Building designers pay the highest professional liability premiums, averaging $1,705 per year, while finance and accounting professionals pay just $400.
