Start with the work promised to the client.
For All Other Professional, Scientific, and Technical Services, clarify the services, contracts and consequences of an error. Review professional liability (e&o), third-party financial harm, premises and field liability. Confirm which professional activities and additional services the proposed coverage actually addresses.
Questions to ask
- What specific service does the business provide — appraisal, inspection, arbitration, counseling, or something else? The actual operation matters far more than the NAICS code for placement.
- Are services delivered primarily in an office or remotely, or does the work involve regular on-site visits to client premises, industrial facilities, vessels, or infrastructure?
- What industries do clients represent — individual consumers, financial institutions, industrial operators, government entities?
- Does the insured sign contracts with clients, and do those contracts include indemnification, hold-harmless, or additional insured requirements?
- Is any sensitive personal, financial, or proprietary technical data collected, stored, or transmitted in the course of work?
- Are any independent contractors or freelancers used to deliver services, and if so, do those contractors carry their own professional liability coverage?
- Has the business had any professional liability claims, errors and omissions disputes, or licensing or regulatory actions in the past five years?
- What are the typical contract values or fee sizes — and what is the potential financial consequence to a client if the insured's work product contains an error?

Businesses in this class provide professional, scientific, or technical services that don't fit more specific NAICS categories — examples include personal property appraisers, marine surveyors, commodity inspectors, pipeline and power line visual inspectors, arbitrators, patent brokers, consumer credit counselors, and weather forecasters. Day-to-day work may involve on-site inspections, analysis and reporting, client advisory services, or specialized technical assessments, depending heavily on the specific sub-type of service offered.
