Every question in this comparison reduces to one: when something goes wrong, what gets hurt? If the answer is a body or somebody else's property — a person, a floor, a server rack — you're in general liability territory. If the answer is money — a penalty, a blown launch, a hole in a client's balance sheet — you're in professional liability territory. Hold onto that question; it sorts real claims faster than any policy summary. This guide runs the two policies side by side, draws the boundary with five concrete scenarios, and finishes with the honest answer for the trades that need both.

Side by side

	General liability	Professional liability (E&O)
Covers	Bodily injury and property damage to third parties	Financial loss caused by your professional work
Typical claimant	A customer, a bystander, a client's landlord	A client
Classic claim	The slip-and-fall; your ladder through their window	The error, the omission, the missed deadline
Policy form	Almost always occurrence	Usually claims-made
Defense costs	Typically outside the limits	Often inside the limits
The contract ask	$1M/$2M on a certificate of insurance	$1 million E&O in the master service agreement
Published cost context (as of mid-2026)	$45 a month median — Insureon	About $62 a month consultant median — Insureon

The rows get unpacked below, but keep the structural point: these are complements, not rivals. Neither policy reaches the other's lane, which is exactly why contracts increasingly demand both.

General liability: the physical-harm policy

General liability responds when your business operations injure someone who doesn't work for you or damage property that doesn't belong to you — and it funds the lawyers when someone claims you did. The classic claims are physical and visual: a client trips over your extension cord, your ladder meets a window, the shelf you installed last month pulls out of the wall this month (that last one is products–completed operations coverage, the part of GL that follows your finished work). What GL never covers is just as load-bearing: your professional judgment, and the cost of re-doing your own botched work — the "damage to your work" exclusions draw that line hard. Our general liability explainer walks the full policy anatomy, and our GL cost guide breaks down the pricing drivers.

Professional liability: the financial-harm policy

Professional liability — errors and omissions, E&O, same policy — responds when a client claims your professional work cost them money. The covered shapes: errors (the bookkeeper's transposed account that triggers a tax penalty), omissions (the requirements document that skipped a compliance step), negligent advice, and missed deadlines that turn into client losses. No ambulance, no broken glass — just a client, a spreadsheet, and a demand letter. A large share of the value is defense funding, because professional claims are argument-shaped: was the work below standard, or did the client mismanage the engagement? One nuance to price-check when you shop: in many E&O forms, defense costs sit inside the limit, eroding what's left for the claim itself — GL usually works the other way. Our professional liability explainer covers the mechanics in depth.

The boundary, drawn with five claims

1. The IT consultant. Knocks over a client's server rack while re-cabling: physical damage to client property — GL. Botches the migration and the client loses a week of orders: financial harm from professional work — E&O. Same visit, same consultant, two different policies.

2. The photographer. A light stand falls on a wedding guest — GL, bodily injury. The memory card fails and the ceremony photos are gone — E&O, a professional deliverable that failed. (The camera gear itself is neither; that's property coverage territory.)

3. The bookkeeper. Spills coffee into a client's laptop during a site visit — GL, plain property damage. Transposes an account and the client eats a penalty — E&O. The tool that broke decides nothing; what got hurt decides everything.

4. The contractor. Installs a shelf that later falls and shatters a client's vase — GL, completed operations. Measures wrong so the cabinets don't fit and must be rebuilt — neither policy pays. Re-performing your own work is business risk, not insurable loss; that's the bad-work myth our GL explainer spends a section killing.

5. The marketing shop. A competitor claims your client campaign disparaged them — surprisingly, often GL, under Coverage B's personal and advertising injury. The campaign underdelivers and the client demands their fee back — that's a fee dispute, and mostly neither (E&O covers negligence, not refunds). The boundary has trapdoors on both sides, which is why you read the forms.

The trades that genuinely need both

Draw the Venn: one circle for businesses that work around people and property, one for businesses that sell judgment and deliverables. The overlap is wide, and it's where both policies belong:

• IT consultants and dev shops working on client sites — rack accidents and migration failures live in different circles.
• Photographers and videographers — dropped lights and lost files.
• Designers and architects-adjacent trades whose drawings become physical things.
• Inspectors and appraisers — site visits plus consequential opinions.
• Marketing and creative agencies — client offices, client campaigns.
• Trainers and instructors — injuries in session, advice out of session.

Client paperwork confirms the theory: vendor onboarding increasingly asks for GL and E&O limits on the same certificate. Our COI guide shows where each line lands on that document.

Occurrence vs. claims-made: the difference that outlives the purchase

The quiet structural split from the table deserves a beat, because it governs how the policies age. GL is almost always an occurrence form: it answers for anything that happened while it was active, even if the claim arrives years after you've moved on. Professional liability is usually claims-made: it answers only if a policy is active when the claim arrives, with a retroactive date fencing how far back the covered work reaches. Practical consequences: never let an E&O retroactive date reset when switching carriers, and budget for tail coverage before you wind down, or claims on past work land on no coverage at all. The full timeline diagram lives in our professional liability explainer; the one-line version is that GL ages gracefully and E&O has to be maintained.

Which do you need — by trade

Your work	The lean
Physical trades: cleaning, landscaping, handyman, light construction	GL first — E&O is rarely asked of you
Pure advice: consultants, coaches, bookkeepers, designers, developers	E&O first — add GL for offices, site visits, and client-host requirements
Both worlds: IT, photographers, inspectors, design-build, agencies	Both — often cheapest quoted together
Product sellers: e-commerce, makers, food	GL with product liability; E&O only if you also advise

When the table gives you a tie, let the paperwork break it. Pull your two or three most important client contracts and read the insurance clause. If it names commercial general liability and certificate limits, that's your buy. If it names professional liability, errors and omissions, or E&O — standard once a client has a legal department — that's your buy. If it names both, so does your answer. The contract is a better underwriter of your actual exposure than any generic advice, because it was drafted by the party most likely to sue you.

Two adjacent lanes for completeness: employee injuries are workers' comp — required by law in most states at the first employee, thresholds vary, confirm with a licensed agent in your state — and data exposure is cyber liability, which neither GL nor E&O meaningfully reaches.

What the pair typically costs

Sourced figures only, ranges never promises. As of mid-2026, Insureon's published median for small-business general liability is $45 a month, and its consultant E&O median runs about $62 a month. On the advertised-floor side, Hiscox lists professional liability from $22.50 a month and general liability from around $30 a month — real numbers, but floors for the lowest-risk profiles, not typical rates; our Hiscox review decodes the from-price honestly. Where you land depends on trade, state, revenue, limits, and claims history. Every figure on this page carries its source and date — see our methodology.

How to buy — ideally in one sitting
