Introduction
Business insurance comes in many forms. Two of the most common policies are professional liability insurance and general liability insurance. Many business owners confuse these two or believe one replaces the other. That mistake can lead to uncovered claims and financial loss.
Both policies protect against lawsuits, but they cover different risks. Understanding how they work helps you choose the right protection for your business.
This article explains professional liability and general liability in simple terms. You will learn what each policy covers, how they differ, who needs them, and when both are required.
What Is Professional Liability Insurance?
Professional liability insurance protects businesses and individuals who provide services or advice.
It covers claims that arise from:
- Errors
- Omissions
- Negligence
- Misrepresentation
- Failure to deliver promised services
This insurance is often called:
- Errors and omissions insurance
- E&O insurance
It focuses on financial loss caused by your professional work.
Example:
A consultant gives advice that leads to a client losing money. The client files a lawsuit claiming the advice caused damage. Professional liability insurance may help pay legal costs and settlements.
What Is General Liability Insurance?
General liability insurance protects against physical and non-professional claims.
It usually covers:
- Bodily injury
- Property damage
- Personal injury
- Advertising injury
- Medical payments
It applies to accidents that happen during daily business operations.
Example:
A customer slips inside your office and gets injured. General liability insurance may pay medical bills and legal expenses.
Core Difference Between the Two
The main difference is the type of risk they cover.
Professional Liability
Covers financial harm caused by your services or advice.
General Liability
Covers physical harm, property damage, and advertising-related claims.
They do not overlap. Each policy handles a separate category of risk.
What Professional Liability Insurance Covers
Professional liability insurance usually includes:
Service Errors
Mistakes made while providing services.
Example:
An accountant files incorrect tax forms.
Negligence Claims
Claims that you failed to meet industry standards.
Example:
A designer delivers work that does not follow agreed specifications.
Missed Deadlines
Clients may claim loss because you failed to complete work on time.
Incomplete Work
Coverage may apply when services are not delivered as promised.
Legal Defense Costs
Even false claims require lawyers. Professional liability insurance often pays for:
- Attorney fees
- Court costs
- Investigation expenses
- Settlements
What Professional Liability Insurance Does Not Cover
Most policies exclude:
- Bodily injury
- Property damage
- Employee injuries
- Fraud
- Intentional wrongdoing
- General accidents
These risks belong under other policies.
Who Needs Professional Liability Insurance?
Any business that provides services or advice should consider professional liability insurance.
Examples include:
- Consultants
- Designers
- Accountants
- Lawyers
- IT professionals
- Marketing agencies
- Architects
- Engineers
- Freelancers
- Trainers
If clients rely on your expertise, this coverage matters.
What General Liability Insurance Covers
General liability insurance typically includes:
Bodily Injury
Covers injuries to third parties at your location or caused by your operations.
Property Damage
Pays for damage to property owned by others.
Personal Injury
Includes claims such as defamation or false arrest.
Advertising Injury
Covers copyright infringement, libel, and slander in marketing materials.
Medical Payments
Pays minor injury costs without requiring a lawsuit.
What General Liability Insurance Does Not Cover
General liability insurance usually excludes:
- Professional mistakes
- Employee injuries
- Damage to your own property
- Auto accidents
- Cyber incidents
These gaps require other policies.
Who Needs General Liability Insurance?
Almost every business benefits from general liability insurance.
This includes:
- Retail stores
- Restaurants
- Contractors
- Home-based businesses
- Online sellers
- Manufacturers
- Event planners
If customers or visitors interact with your business, this coverage matters.

Do You Need Both Policies?
Many businesses need both.
Service-based companies often face professional claims and physical risks.
Example:
A marketing agency:
- Could face copyright claims from ads
- Could face injury claims from office visitors
Without both policies, one of these risks remains uncovered.
Cost Differences
Pricing depends on:
- Industry
- Revenue
- Claims history
- Coverage limits
- Location
General liability often costs less for low-risk businesses.
Professional liability can cost more in fields with high financial exposure.
Many small businesses pay:
- General liability: $30–$80 per month
- Professional liability: $40–$120 per month
These numbers vary by business type.
Policy Limits Explained
Both policies use:
Per Claim Limit
Maximum paid for one claim.
Aggregate Limit
Maximum paid during the policy year.
Once limits are reached, coverage stops.
Claims-Made vs Occurrence Policies
Professional liability insurance usually works on a claims-made basis.
This means:
- The policy must be active when the claim is filed.
General liability insurance usually works on an occurrence basis.
This means:
- The policy must be active when the incident happens.
Understanding this difference matters when switching insurers.
Contract Requirements
Many clients require proof of both policies before signing agreements.
Common contract requests include:
- General liability certificate
- Professional liability certificate
- Specific coverage limits
Without these, you may lose business opportunities.
Bundling Insurance Policies
Many insurers offer packages such as:
- Business owner’s policy
- Professional package
Bundling may reduce total cost and simplify management.
How to Choose the Right Coverage
Step 1: Identify Your Risks
Ask:
- Do clients depend on my advice?
- Do people visit my location?
- Do I handle client property?
Step 2: Review Contracts
Check coverage requirements from landlords or clients.
Step 3: Compare Quotes
Look at:
- Coverage details
- Limits
- Exclusions
- Deductibles
Not just price.
Step 4: Update Policies Regularly
As your business grows, coverage should change too.
Common Mistakes Business Owners Make
- Buying only general liability
- Skipping professional liability
- Choosing low limits
- Not reading exclusions
- Forgetting to renew claims-made policies
These mistakes lead to denied claims.
Small Businesses and Liability Risk
Many owners believe lawsuits only target large companies.
Small businesses face claims too.
Legal costs alone can exceed yearly revenue.
Insurance provides financial support when disputes happen.
Online Businesses and Service Providers
Digital businesses still face liability:
- Client disputes
- Advertising claims
- Contract issues
Professional liability protects service errors.
General liability protects visitor injuries and shipping damage.
When to Buy Coverage
Buy insurance before:
- Opening your business
- Signing contracts
- Accepting clients
- Renting office space
- Launching services
Waiting increases exposure.
Final Thoughts
Professional liability and general liability insurance serve different purposes.
Professional liability protects against mistakes in your work.
General liability protects against accidents and physical claims.
One does not replace the other.
Many businesses need both to fully protect their operations, income, and assets.
Understanding these differences helps you avoid coverage gaps and prepares your busines
