Update the insurer before operations change, and ask which forms address each stage. [Launch your business — Get business insurance](https://www.sba.gov/counseling/launch-your-business/), [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ## Which Insurance Should You Consider? Consider professional errors and omissions (E&O), general liability, commercial property, tools, equipment and inland marine, equipment breakdown, and product liability. Start with the coverages tied to your day-to-day operations, then use the situations and buying questions below to compare your options. ### [Professional errors and omissions (E&O)](https://spot.insure/coverage/professional-errors-omissions) **When it matters:** A customer will build, install, or decide from your drawings, specifications, tests, code, or design advice. [Small Business Insurance](https://content.naic.org/consumer/small-business.htm), [Launch your business — Get business insurance](https://www.sba.gov/counseling/launch-your-business/) **What to review:** Professional liability is described broadly for service or advice errors. Ask how the form defines your work; do not assume product injury is handled by E&O. [Small Business Insurance](https://content.naic.org/consumer/small-business.htm), [Launch your business — Get business insurance](https://www.sba.gov/counseling/launch-your-business/) **Ask:** Which design, testing, engineering, and implementation services are listed, and how are rework or alleged financial loss treated? [Small Business Insurance](https://content.naic.org/consumer/small-business.htm), [Launch your business — Get business insurance](https://www.sba.gov/counseling/launch-your-business/) ### [General liability](https://spot.insure/coverage/general-liability) **When it matters:** You host customers in a workshop, demonstrate a prototype, or work at a pilot site. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm), [Small Business Insurance](https://content.naic.org/consumer/small-business.htm) **What to review:** Commercial general liability addresses categories such as bodily injury and damage to others’ property. Compare testing and installation work with described operations and exclusions. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm), [Small Business Insurance](https://content.naic.org/consumer/small-business.htm) **Ask:** Are workshop visits, demos, customer-site testing, and installation listed, and which exclusions or limits affect them? [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm), [Small Business Insurance](https://content.naic.org/consumer/small-business.htm) ### [Commercial property](https://spot.insure/coverage/commercial-property) **When it matters:** You lease a workshop or buy test rigs, machinery, prototypes, or inventory. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **What to review:** Property terms depend on scheduled locations, values, covered causes, and exclusions. Include customer-owned property separately in the discussion. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **Ask:** Which building interests, machinery, tools, prototypes, stock, and customer property are listed and on what valuation basis? [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ### [Tools, equipment and inland marine](https://spot.insure/coverage/inland-marine) **When it matters:** Your team carries prototypes, tools, or test equipment to pilots, customer sites, or trade shows. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **What to review:** Ask which form schedules property while it is in transit; workshop property terms do not establish protection for every trip. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **Ask:** Which items, destinations, loading, testing, and installation stages are scheduled, and what limits or causes apply in transit? [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ### [Equipment breakdown](https://spot.insure/coverage/equipment-breakdown) **When it matters:** A test machine or production system failure could stop a milestone. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **What to review:** Ask whether separate machinery-breakdown terms apply, which equipment and failure causes qualify, and what resulting damage or income-loss terms are included. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **Ask:** Which machines and failure causes qualify, and does the quote address resulting damage, temporary equipment, or income loss? [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ### [Product liability](https://spot.insure/coverage/product-liability) **When it matters:** You ship hardware, combine software with a device, or complete an installation that could injure someone or damage property. [Launch your business — Get business insurance](https://www.sba.gov/counseling/launch-your-business/), [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **What to review:** SBA distinguishes product liability for businesses making or selling products. Ask how the actual products/completed-work wording applies to your products and territories. [Launch your business — Get business insurance](https://www.sba.gov/counseling/launch-your-business/), [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) **Ask:** Which product versions, installations, and territories are described? Ask separately whether any recall expense form is quoted. [Launch your business — Get business insurance](https://www.sba.gov/counseling/launch-your-business/), [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ## Need Help Choosing Coverage? Spot prepares your applications, coordinates with brokers, and helps you compare quotes so you can choose coverage with the key details in front of you. [Book a Free Consultation](https://cal.com/team/spotinsure/insurance-consultation) ## Before a Prototype Leaves the Workshop List the prototypes and tools that will travel, who owns each item, and where they are going. Ask which form schedules property away from the workshop; do not assume workshop terms cover every trip. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) If customers are present during testing, describe the activity and who controls it. Ask about visitor injury and damage to someone else’s property under the quoted operations description. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm), [Small Business Insurance](https://content.naic.org/consumer/small-business.htm) ## When a Design Becomes a Product Tell the insurer when you move from client design to making, importing, distributing, or selling. Describe the device, software/hardware mix, installation, user, and territory. Ask how the quote treats service errors and product allegations. [Launch your business — Get business insurance](https://www.sba.gov/counseling/launch-your-business/), [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) For a covered consumer product and a covered manufacturer, importer, distributor, or retailer, certain safety information can trigger a CPSC reporting question before anyone is injured. The reporting duty depends on the product and your role; a report does not establish insurance response. [Duty to Report to CPSC: Rights and Responsibilities of Businesses](https://www.cpsc.gov/Business--Manufacturing/Recall-Guidance/Duty-to-Report-to-CPSC-Rights-and-Responsibilities-of-Businesses) ## Before You Lease or Buy Equipment Separate building interests, installed machinery, movable tools, prototypes, inventory, and customer property. Give the broker values and locations before signing the lease. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) Ask whether a machine breakdown needs separate terms and what income or extra-expense trigger applies. A property label does not explain breakdown response. [Commercial Insurance Guide](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm) ## Providers to Compare by Coverage These providers document the coverage listed below. Examples are alphabetical, not a ranking or confirmation that your business qualifies.

Compare the proposed E&O definition of your design services with the CGL/products terms for injury or property damage caused by your product. Check each form’s exclusions and covered activities. [Small Business Insurance](https://content.naic.org/consumer/small-business.htm), [Launch your business — Get business insurance](https://www.sba.gov/counseling/launch-your-business/) [Read the full answer](https://spot.insure/industries/engineering-product-design/does-eo-cover-product-injury) ### What happens to equipment coverage when a prototype goes to a pilot? Ask which form schedules the prototype or tools away from the workshop, and whether it addresses the trip, test site, and installation stages. Check the actual schedule and wording.
