What is Custom Computer Programs or Systems Software Development?
This coverage helps protect businesses that design, develop, test, maintain or sell custom software and systems. Policies focus on professional liability exposures from errors or omissions in code, plus broader risks such as property damage or third-party bodily injury that can arise during development, delivery, or installation.
Who needs it
Typical buyers include independent software developers, boutique development shops, systems integrators and in-house development teams at manufacturers, retailers or technology operators. Smaller organizations like clubs or associations that build or operate custom systems can also need tailored protections. Firms that provide ongoing support or host client applications should evaluate both professional liability and technology errors & omissions coverage.
What it typically covers
Policies vary, but common elements include defense and indemnity for claims of coding errors or failures to perform, intellectual property disputes, and sometimes first- and third-party data breach response. Insurers may also offer endorsements for property coverage, equipment coverage, or limits related to commercial auto exposure when transportation of hardware is part of the service.
For more specific technology-focused options, see Computer Software Development and Applications Insurance and developer-focused products such as Custom Computer Programming Services Insurance.
Common exclusions or limitations
Expect exclusions for intentionally fraudulent acts, contractual liabilities that exceed negligence, and some cyber exposures unless a specific cyber endorsement is added. Policies also often limit coverage for known claims, punitive damages in jurisdictions where they are not insurable, and certain intellectual property claims without prior underwriting review.
Factors that influence cost
Underwriting factors include annual revenue, contract size, claim history, types of clients served, code review and testing practices, and whether the company uses subcontractors. The technology stack, data sensitivity, and the presence of formal risk management policies also affect pricing. Higher-risk operations—such as those working with critical infrastructure or heavily regulated data—will typically see higher premiums.
Proof of insurance & compliance
Clients and partners often request certificates of insurance and specific endorsements showing limits and additional insured status. Some contracts require minimum limits or that defense costs be outside the policy limits; review contract requirements carefully and discuss endorsements with your broker.
How to get a quote
Gather basic information—revenue, a summary of services, top clients, claims history, and any security/testing protocols—to speed underwriting. If you need help interpreting contract insurance requirements, Custom Software Programming Insurance resources can be useful. When you’re ready, talk to your agent for a tailored quote and to discuss appropriate limits and endorsements.
Risk scenario example: a third-party claim arising from a deployment error that interrupts client operations illustrates how professional liability and related coverages work together.
Frequently Asked Questions
Do standard business liability policies cover software errors?
No. Standard commercial general liability policies usually exclude professional errors in software design or performance; a technology professional liability or errors & omissions policy is designed for those risks.
Should I buy cyber insurance separately?
Cyber coverage is often a separate policy or endorsement. If your work involves client data, consider cyber liability for breach response, notification costs and regulatory exposures in addition to professional liability.
Can clients require me to add them as an additional insured?
Yes, clients commonly request additional insured endorsements or specific limits in contracts. Discuss these requirements with your broker early to ensure the policy can meet contractual obligations.
