Tech Errors & Omissions Insurance

E&O insurance covers the legal costs when a client claims your work caused them a measurable loss, including attorney fees, court costs and settlements or judgments up to your policy limit. In tech and IT, that means claims tied to buggy code that broke a client's workflow, a system migration that caused data loss or consulting advice that led to a failed implementation. When a claim is filed, your insurer assigns a defense attorney, manages the legal process and pays covered costs up to your per-occurrence limit, with any amount above that limit coming out of pocket.

E&O is written as a claims-made policy, so coverage applies only to claims both made and reported while the policy is active. Two dates control what's covered: the retroactive date sets how far back your covered work goes, and the policy expiration date sets the deadline for reporting claims. A client can file months after a software project closes, so tech businesses switching insurers or buying E&O for the first time should confirm their retroactive date reaches back far enough to cover active and recently completed work.

Not every tech business has the same E&O exposure, and need varies more by what you do and who you do it for than by business size. A solo web designer working on small local projects carries far less E&O exposure than a software development firm delivering custom platforms for enterprise clients. The primary factors that determine whether you need errors and omissions (E&O) insurance in tech are client type, contract language and the degree to which a client depends on your work to run their business. Where clients are large, contracts are formal and system failures carry real financial consequences, E&O stops being optional. The breakdown below covers the most common tech business situations and where E&O fits:

For tech and IT businesses, E&O insurance covers the gap between what a client expected and what they got. The six claim categories below reflect the situations tech firms are most likely to encounter.

The average cost of E&O insurance for tech and IT businesses is $74 per month ($888 per year) for a business with one to four employees. What you pay depends on the type of systems you work on, the value of client contracts you carry, whether your engagements involve third-party integrations or subcontractors and how much of your client's operations depend on your work running correctly. Web designers average $65 per month while managed service providers average $79, a spread that reflects the difference in claim exposure between a business building marketing sites and one managing mission-critical infrastructure for multiple clients.

The table below shows average monthly and annual E&O premiums by business type:

E&O is only one part of your tech business insurance costs. If you want to see how much errors and omissions coverage costs for different tech sub-industries, review the resources below:

The standard starting point for tech and IT businesses is $1 million per occurrence / $2 million aggregate, and most insurers use that as their baseline for new policies. But that floor doesn't fit every tech operation equally. An MSP managing infrastructure for a dozen enterprise clients carries far more exposure than a solo developer building websites, and if a system failure triggers a claim, the size of that claim tracks directly to how much your client's business depends on your work.

Many enterprise and government contracts specify minimum E&O limits before a vendor can start work, so the contract often sets your floor before you do. How much E&O insurance you need beyond that depends on your client profile and what a worst-case claim would cost your client. Use the profiles below to find the limit range that matches your client type and contract terms.

E&O insurance is the policy most likely to get used in a tech business because client claims follow professional work, and professional work is what tech businesses sell. Your client dependency is the right lens: the more a client's operations rely on your work, the more exposure you carry and the more coverage you need. Use your contracts, your client profile and your subcontractor exposure to set your limit, and revisit it when either changes. Once E&O is in place, add cyber liability next. For tech businesses handling client data or running connected systems, the two policies cover different risks and work together as a baseline.

Once you understand what E&O covers and what it costs, the natural next questions are whether you need it, how much to carry and what else belongs in your coverage stack. The scenarios below reflect where most tech businesses are still making decisions.

E&O pricing varies enough between insurers that the provider quoting the lowest rate for a web design freelancer may not be the most competitive option for a managed service provider running infrastructure for enterprise clients. What drives the difference is exposure: client contract values, the complexity of your engagements, whether you work with subcontractors and whether your clients have uptime dependencies or active deployment cycles that create direct liability if your work fails.

A solo web developer on small project-based work and an MSP managing systems for multiple enterprise clients carry different risk profiles, and insurers price to match. Select your business type and state to get matched with a provider and request E&O quotes based on your actual tech business profile.
