Two Different Policies for Two Different Risks
General liability and professional liability are both business insurance policies, and both protect against lawsuits. The difference is in what kind of claims they're designed to cover.
General liability covers the physical world: someone gets hurt near your business, you accidentally damage a client's property, your marketing causes a legal dispute. These are risks that exist because your business operates in physical spaces and interacts with people and property.
Professional liability — also called errors and omissions (E&O) or malpractice insurance depending on the industry — covers the professional world: the advice you give, the work product you deliver, the service you provide. If your professional judgment or service causes financial harm to a client, professional liability is what responds.
General Liability: What It Covers
| Scenario | Covered by CGL? |
|---|---|
| Customer slips at your business location | Yes |
| You damage a client's property during work | Yes |
| Copyright infringement in your advertising | Yes |
| A visitor is injured at your job site | Yes |
| A completed project fails later, causing damage | Yes (completed operations) |
Professional Liability: What It Covers
| Scenario | Covered by E&O? |
|---|---|
| Your advice led to client financial loss | Yes |
| You missed a deadline causing client damages | Yes |
| Your work didn't meet the contracted standard | Yes |
| A client says you gave them incorrect information | Yes |
| Your design had an error that required rework | Yes |
Which One Do You Need?
If you primarily do physical work — construction, cleaning, landscaping, manufacturing — general liability is your foundation. Professional liability may or may not apply depending on whether you provide advice or design services alongside the physical work.
If you primarily provide professional services — consulting, IT, marketing, financial advice, legal services, architecture — professional liability is essential. General liability still matters for premises and physical interactions, but E&O is the policy that addresses your primary risk.
If you do both — a contractor who also designs systems, an IT company that consults and does installation work, a marketing firm that also does video production — you need both.
Do Contractors Need Professional Liability?
Sometimes. Most contractors are covered by their CGL policy for the work they perform. But if a contractor provides design input, gives structural advice, or specifies materials as part of their service, there's a professional element to the engagement that general liability doesn't address.
For example: a general contractor who designs a custom deck in addition to building it has both physical execution risk (covered by CGL) and design advice risk (potentially needing E&O).
When Clients Require Both
Corporate clients, government agencies, and sophisticated commercial clients increasingly require vendors to carry both general liability and professional liability before signing contracts. Technology companies, marketing agencies, consultants, and engineering firms regularly encounter this requirement.
If you're seeing dual insurance requirements in your contracts, that's a signal that the client has seen claims in both categories and wants protection accordingly.
Cost Comparison
For small businesses, professional liability (E&O) policies typically run $50–$200 per month depending on your profession and revenue. General liability for the same businesses runs $35–$150 per month. When both are needed, bundled pricing is sometimes available through carriers that offer both in a combined policy.
The right answer is to get both if your work has any professional services component, and review the requirements in your contracts to ensure you're meeting what clients actually need from you.
