Coverage coordination
Start with the operational change
The question often appears when a team begins performing implementation, training, managed services, or onsite work. A customer’s loss may be financial, physical, or both, and the facts shape the coverage review.
A technician installing equipment at a customer site, a consultant configuring software, and a customer alleging inaccurate professional advice can produce materially different fact patterns. Build the review from the activity and alleged harm rather than from the policy label.
Keep a current map of where people work, whether hardware is handled, and whether the company controls the customer environment. These details help distinguish premises-and-operations questions from service-performance questions.
Read the professional-services exclusion
General liability policies commonly contain exclusions affecting professional services. Compare the exclusion’s defined services and any carve-backs with the E&O insuring agreement. Do not assume the same activity is treated alike in each form.
Read the exclusion with the same care as the insuring agreement: identify the services it names, whether it applies to insureds or all work, and whether an endorsement changes it. Then compare that language with the E&O form’s covered professional services.
A certificate or proposal summary is not enough for this comparison. Request the relevant policy form, declarations, and endorsements before concluding that a contract requirement is satisfied.
Map the agreement to the policy
Gather statements of work, scopes, certificates requested by a client, and indemnity clauses. Then identify what was promised, who performed it, and whether subcontractors or customer premises change the picture.
For each material customer contract, list the deliverables, locations, use of subcontractors, acceptance process, indemnity, and insurance requests. A short table makes it easier to see which promises are operational and which are insurance-related.
If a client requests additional insured status, do not treat that request as a substitute for a technology E&O review. The requested status, if available, may be connected to a particular policy and operations.
Document decision points
Record the services described in the application and update them before renewal if delivery changes. Ask which policy definitions, exclusions, retentions, and defense arrangements should be compared. Policy wording, declarations, and endorsements control.
At renewal, compare the current service map with the application submitted last year. A new onsite deployment, hardware component, or managed-service obligation may warrant a different question than an unchanged subscription business.
This article does not allocate a claim between policies. The facts, policy wording, declarations, endorsements, and applicable law control.
Use the alleged harm to start the comparison
Commercial general liability is often examined for bodily injury, physical property damage, and certain personal or advertising injury allegations, while technology E&O is examined for specified service or product errors that cause covered loss. Those are broad descriptions, not claim outcomes. A software deployment can involve physical equipment, an onsite visitor, inaccurate work, and a customer’s financial loss in the same project. Write down the actual allegation and requested remedy before choosing which form to read.
For example, a team member may damage a customer-owned device while onsite, while a separate data-mapping error delays the customer’s operations. Treating both as one “implementation claim” can hide the different insuring agreements, exclusions, and deductibles that need review. The factual sequence and policy wording matter more than the project name.
Check for gaps created by exclusions and definitions
Read the general-liability professional-services exclusion and any technology-specific exclusions, then read the E&O definition of covered technology products or services. Ask whether onsite installation, consulting, customer training, managed support, data migration, or work by a subcontractor appears in either document. A narrow definition on one side and a broad exclusion on the other deserve a documented question.
Also compare who is insured, where the work occurs, what period applies, and whether claims-made reporting or retroactive dates affect the E&O side. A certificate listing both policies is not a substitute for reading the actual forms. No checklist can allocate a real claim without its facts and issued terms.
Bring the customer contract into the analysis
A customer may require general liability and technology E&O, ask for additional-insured status, and set an indemnity obligation. Record each requirement separately. An additional-insured endorsement for certain general-liability operations does not automatically make a customer an insured under the E&O form. A contractual promise to reimburse the customer can also be broader than what an insurance policy agrees to pay.
Use a one-page review table with the contracted service, location, people performing it, potential physical interaction, promised outcome, requested insurance document, and policy clause to examine. Where a requirement cannot be met, bring it back to the commercial and legal owners before signature rather than relying on a certificate description.
When to reopen the review
Revisit the GL/E&O boundary when the company adds hardware, sends employees to customer sites, performs more hands-on services, changes subcontractors, enters a new customer sector, or introduces a product that influences safety or physical processes. These are prompts for fact-specific review, not automatic reasons to buy a particular form.
Keep the prior and current service inventory, submitted application, policy forms, endorsements, and contract exceptions together. At renewal, compare what changed and ask the insurer or intermediary to confirm the intended description in writing. Policy wording, declarations, endorsements, facts, and applicable law control.
One comparison question that catches mistakes
Ask the reviewer to identify a real service the company performs that is excluded or not clearly named in the E&O proposal, then ask whether the general-liability form would also restrict it. An unanswered overlap question is more valuable to surface before binding than after a customer alleges loss.
