Business Insurance for Service Businesses

Why this matters

A service-business owner who's been doing the work for years intuitively knows the day-to-day risks: a technician falls off a ladder, a tool damages a customer's floor, a truck rear-ends another car at a stoplight. What's less intuitive is which insurance products actually cover those events, where the gaps are between policies, and what the consequences look like when an uninsured event happens. A single uninsured liability claim can erase a decade of profit and threaten the business's existence. Insurance is not optional for any service business, and the policy choices made early often determine whether a catastrophic event becomes a setback or an extinction event.

The core policies every service business needs

A typical multi-truck service business carries 6-10 of these policies, often bundled by a single carrier through a Business Owners Policy (BOP) plus separate auto and workers' comp.

General Liability (GL)

The foundational policy. GL covers:

• Customer or third-party bodily injury from your operations.
• Property damage to non-customer property.
• Personal and advertising injury (libel, slander, copyright in ads).
• Medical payments to injured third parties.
• Defense costs even for unfounded claims.

GL does NOT cover:

• Damage to property you're working on (typically excluded; some policies cover "your work" with endorsement).
• Employee injuries (workers' comp).
• Auto incidents (commercial auto).
• Professional advice errors (E&O).
• Damage from completed work that later fails (products/completed operations is sometimes a separate sub-coverage).

Limits: the residential service contractor baseline is written as 1M per occurrence over a 2M aggregate, the aggregate running double the per-occurrence limit. Commercial work commonly demands double that on both figures or more. Limits are a coverage specification, not a price, so quote the layer the certificate holder demands and let the broker price it.

Commercial Auto

Personal auto insurance has a commercial-use exclusion. A vehicle used regularly for business work isn't covered under personal policies - a claim will be denied at exactly the wrong moment.

Commercial auto policies include:

• Liability - bodily injury and property damage to third parties.
• Physical damage - collision and comprehensive on your vehicles.
• Uninsured/underinsured motorist - when the other driver has inadequate coverage.
• Medical payments / personal injury protection (PIP).
• Hired and non-owned auto - coverage for vehicles employees drive that aren't titled to the business (employee's own car used for work errands).

Higher liability limits matter because auto accidents with serious injuries blow through a state-minimum policy immediately. Carry at least the same 1M per-occurrence layer you carry on GL, and double it for higher-risk operations (crane trucks, hot work, heavy trailers).

Workers' Compensation

State-mandated in every state except Texas. Covers:

• Medical expenses for work-related injuries.
• Lost wages while the employee recovers.
• Permanent disability benefits.
• Death benefits.

Premiums are based on payroll and the classification code for the trade. Codes range from low-risk (clerical, code 8810) to high-risk (roofing, code 5551). Rates are quoted as a rate per hundred of payroll, and a high-code class pays several times what a clerical class pays on the identical payroll. Getting a tech coded correctly is worth more than shopping carriers.

Experience modification (EMR or "mod") adjusts the premium based on the business's claim history. A mod below 1.0 saves money; above 1.0 costs more. Some commercial contracts require an EMR below a threshold to bid.

Misclassifying employees as 1099 contractors to avoid workers' comp is a serious mistake - the IRS, state DOL, and insurance carriers all aggressively pursue this, with severe consequences including back premiums, penalties, and personal liability for the owner.

Cyber Liability

A newer category that's become essential. Covers:

• Data breach notification costs.
• Forensic investigation.
• Legal counsel for regulatory response.
• Credit monitoring for affected individuals.
• Ransomware payments and recovery (sometimes).
• Business interruption from cyber events.
• Liability claims from affected customers.

Modern cyber policies often require security baselines as a condition: MFA on email, endpoint protection, backup verification, employee training. Misrepresenting those controls on the application can void coverage exactly when it's needed most.

Meaningful cyber liability limits are cheap relative to the exposure, and the math favors carrying it even for a small shop.

Commercial Umbrella

Sits on top of underlying primary policies (GL, auto, EPLI) to provide higher limits. Stacking a 5M umbrella over 1M primary policies gets you an effective 6M tower, and the umbrella layer costs a small fraction of what the primary layer costs because the primary absorbs almost every claim.

When umbrella matters:

• Large commercial accounts often demand a tower several times the residential baseline.
• Catastrophic injury claims (paralysis, brain injury) routinely blow past a 1M primary limit on their own.
• Multiple plaintiffs in a single incident.
• Estate-protection consideration for the owner.

Once a shop is doing seven figures of annual revenue, umbrella coverage is standard practice.

Surety bonds

Different from insurance - a bond is a guarantee that the contractor will perform or pay. State licensing often requires:

• License bond - required by the state for the trade license itself.
• Performance bond - required on specific contracts by the client.
• Payment bond - guarantees the contractor pays subs and suppliers.
• Bid bond - assures the client the contractor will accept the awarded contract.

Bonds aren't optional where required - operating without them violates licensing law and contract terms.

Reading a policy: key terms

Insurance policies are dense and legalistic. Critical terms to understand before you sign:

• Occurrence vs. claims-made. Occurrence policies cover events that happen during the policy period regardless of when claimed. Claims-made policies only cover claims filed while the policy is active, regardless of when the event happened. Switching between the two at renewal can leave old work with no coverage at all.
• Aggregate limit. The maximum the policy pays out in a year across all claims combined.
• Per-occurrence limit. The maximum the policy pays for a single event.
• Deductible. What the business pays out of pocket before the insurer starts paying.
• Exclusions. What the policy does NOT cover. Read this section carefully; it's where surprises happen.
• Endorsements. Additions or modifications to standard policy language, often used to add back a coverage the base form leaves out.
• Subrogation. The insurer's right to pursue the at-fault party for reimbursement after paying your claim.
• Co-insurance. A penalty for being underinsured on property coverage, typically triggered when the insured value falls below a set share of true replacement value.

Buying a policy without reading the exclusions is buying coverage based on what you hope it covers, not what it actually does.
