Tech Errors & Omissions (Tech E&O) Insurance

What Is Tech E&O Insurance?

Technology E&O insurance covers claims from mistakes, failures, or oversights in your services and software. It’s also called professional liability or errors and omissions insurance.

Unlike general liability (bodily injury or property damage) or cyber liability (data breaches), tech E&O covers financial loss from professional negligence. You didn’t do the work right. Or you didn’t do it at all. The client lost money as a result.

The policy covers legal defense, judgments, and settlements. A $50,000 lawsuit stays $50,000 instead of draining reserves.

Who Needs Tech E&O Insurance?

If your business depends on technology expertise, you need tech E&O coverage.

AI companies face some of the highest exposure in the industry. Models that produce incorrect outputs, biased recommendations, or flawed predictions can drive real business decisions and real losses. Our breakdown of artificial intelligence liability insurance covers which policy responds to which AI claim. If a client relies on your AI system to automate a process, flag a risk, or generate analysis, and it gets it wrong, the liability question lands on you.

SaaS companies face specific exposure. Unmet features, downtime, or failed integrations break client workflows. Data loss corrupts customer records. Claims follow for recovery and lost revenue.

IT consultants, system integrators, and MSPs implement infrastructure and manage support. Misconfigurations, missed deadlines, failed migrations, and security oversights create liability. Client operations fail. A claim follows.

Software developers and custom development shops build to spec. But specs change. A bug in production, a missed deadline, or a failed deployment; these drive most E&O claims in the industry.

Data analytics and business intelligence firms advise clients based on analysis. If your analysis is wrong and they lose money, you’re exposed. The stakes are often large.

IT staffing firms place contractors. If your hire causes damage through negligence, vicarious liability can land on you. Even if the contractor carries their own coverage.

IT support and help desk services fix problems fast. Diagnosis errors, failed fixes, or data loss during migration generate claims constantly.

What Tech E&O Insurance Covers

A tech E&O policy protects you from claims alleging:

You contracted to deliver a solution by a date and missed it. Or you delivered incomplete work. The client sues for damages from their delayed operations.

The software, configuration, model, or solution contains defects, bugs, or mistakes. This includes AI outputs that are factually wrong, biased, or inconsistent with documented performance. The client discovers the error only after deploying it. Business impact follows.

You misunderstood what they needed. Or you delivered something that doesn’t match what you both agreed to. They can’t use it.

Your software or model uses third-party IP without proper licensing. This includes copyrighted material incorporated into training data. The IP holder sues your client. Your client sues you. The policy covers it.

A feature you promised doesn’t work. A system fails. An integration breaks.

Your AI system generates a recommendation, prediction, or automated decision that a client acts on. The output is wrong. They lose money, make a bad hire, approve a bad loan, or miss a critical risk. Claims based on AI-driven errors are the fastest-growing category of tech liability. They’re not going away.

During migration, backup, or processing, data disappears, gets corrupted, or becomes inaccessible. Not from a hacker. From your mistake. They sue for recovery costs or lost revenue.

What Tech E&O Insurance Does NOT Cover

Understanding exclusions is as important as knowing what’s in. Tech E&O policies exclude:

Fraud, deliberate breach, or misrepresentation. You’re on your own. The policy doesn’t cover intentional acts.

That’s general liability. If your software causes physical injury or equipment damage, E&O doesn’t apply.

Policies include a retroactive date. Claims from before that date are excluded.

If you agreed to indemnify a client for unlimited liability, the policy may not cover that.

Hacked networks, stolen data, ransomware. These are cyber insurance, not E&O. See our deep dive on network security insurance for how these policies actually respond when your network is the point of failure.

Knowingly breaking regulations, privacy laws, or licensing requirements isn’t covered.

Tech E&O Insurance vs. Cyber Liability Insurance: The Critical Distinction

This is where confusion lives. Many tech companies think E&O and cyber overlap. Or that one covers the other. They don’t. They’re separate risks.

When you make a mistake or miss a deadline. You fail to deliver what you promised. That’s E&O. Your code has a bug. You misconfigured their network. You shipped incomplete work. They sue for damages from your error.

When hackers attack your systems. They breach your network, encrypt your data, steal customer info, or attack through your infrastructure. That’s cyber liability. You didn’t do anything wrong; the attacker did. Cyber insurance covers: breach notification, forensics, legal defense, regulatory fines, credit monitoring, and lost revenue while systems are down.

Real example: A SaaS company implements a new data backup system. A coder makes a mistake in the encryption key generation. Customer backups are accidentally exposed in a public storage bucket. The company discovers it after three months. A customer’s data appears in a breach database.

• The company faces a cyber liability claim for: notifying customers, credit monitoring, forensics, and regulatory fines (the company’s system exposed data, even accidentally).
• The company also faces an E&O claim from customers who suffered identity theft or business damage because the backup system failed to protect their data (professionally negligent architecture).

Both claims exist. Both policies can apply. Neither covers the other perfectly.

Another example: A ransomware gang breaches a managed service provider’s network and holds the infrastructure hostage. Clients lose access to services while the MSP negotiates with the attackers.

• Cyber liability covers the MSP’s cost to negotiate, pay the ransom (if chosen), recover systems, notify parties, and restore service.
• E&O does not apply here. The MSP didn’t fail through negligence. The MSP was the victim of a criminal attack.

Some E&O policies cover “failure to protect data you hold.” That’s E&O. You had a duty to secure it and didn’t. A breach itself (data stolen by hackers) is cyber.

Buy both. Most tech companies we see carry both policies. E&O and cyber insurance are not interchangeable.

How Much Does Tech E&O Insurance Cost?

Cost depends on several factors: company size, annual revenue, specific services, claims history, and desired limits. But here’s what the market shows:

• Average: $67/month ($804/year) for $1M/$1M limits
• Most IT companies we see carry $50–$100/month
• High-risk work (penetration testing, security consulting) runs $100–$150+/month

• Average: $91/month ($1,094/year) for the same limits
• Startups: $31–$153/month depending on revenue and stage
• Most mature SaaS companies carry $75–$125/month for $1M/$2M limits

• Average: $200/month ($2,320/year) for the same limits
• Startups: $100–$190/month depending on revenue and stage
• Most mature AI companies carry $2,000–$350/month for $1M/$2M limits

• Average: $730/year for bundled professional liability + cyber insurance

• Annual revenue: Higher revenue means higher premium (larger exposure)
• Number of employees: More staff generally means higher risk
• Services offered: Custom software development costs more than IT support. Security consulting costs more than help desk.
• Client concentration: Relying on 3–5 major clients increases perceived risk
• Claims history: Clean history gets lower rates. Prior claims increase premiums or may affect eligibility
• Contract terms: Aggressive indemnification clauses with clients may affect pricing
• Limits and deductibles: Higher limits cost more. Higher deductibles lower your premium

• Low end: $1M/$1M (each claim / total)
• Standard: $1M/$2M or $2M/$2M
• Large or high-risk: $3M/$5M or more

Claims Scenario

A 15-person SaaS company sells workforce scheduling software. In February, a major client (a 200-location retail chain) signs a 3-year, $150,000 contract. The client needs a custom integration with their payroll system by May 1 to avoid manual payroll processing during their busiest season.

The SaaS company’s development team encounters unexpected complexity in the payroll API. They notify the client in March that the May 1 deadline is at risk. The client responds that delay is unacceptable and will cost them $20,000 per week in additional payroll processing labor.

By late April, the integration is complete but inadequately tested. It’s deployed on May 1 as promised. On May 15, a bug causes payroll records for 50 locations to duplicate, creating ghost payments and wreaking havoc. The client’s payroll team spends two weeks manually correcting records. They also overpay employees by $15,000 before catching the error.

• $10,000 in additional payroll processing costs (what they said they’d incur if the deadline was missed)
• $15,000 in overpaid wages
• $40,000 in lost productivity and remediation labor
• $50,000 in damages for breach of contract and professional negligence

Total claim: $115,000.

• Legal defense costs (investigation, attorneys, expert witnesses): ~$25,000
• Settlement or judgment: Up to $1M

The company pays its $2,500 deductible. Insurance covers the remaining ~$112,500. Without it, the company faces $115,000+ in immediate cash outflow. That can cripple a 15-person firm.

How to Buy Tech E&O Insurance: What to Look For

A freelancer can operate on $250K/$500K. A 10-person firm needs $1M/$2M minimum. A SaaS company with thousands of users needs $2M/$3M+. Ask: What’s my largest client contract? What’s the worst-case loss if they sue? Your limits should exceed that.

Most policies have a retroactive date. They don’t cover work done before that date. When you switch carriers, align the new retroactive date with your old policy. A gap here leaves you exposed during transition.

General liability covers bodily injury and property damage. E&O is separate. Don’t accept an “errors & omissions” rider on your GL policy. Get a dedicated E&O policy. This matters when you claim.

Some policies bundle legal costs with your settlement pool. Better policies pay legal costs separately. Your full limit stays available for settlement. Ask which type you’re getting.

If your client contracts have indemnification clauses, confirm the policy covers them. Some insurers exclude contractual liability. Know this upfront. Founders facing their first enterprise procurement requirements should also read our guide to startup insurance for enterprise contracts, which walks through what’s negotiable and what’s not.

If you sell or retire, claims can surface years later. Most policies offer tail coverage. Understand the cost. Typically it’s 1–3x your annual premium.

Not all E&O carriers understand SaaS, MSPs, and development equally. Carriers with tech underwriting teams pay claims faster and understand your business. This matters more than price.

Ask your broker about third-party security flaws, IP infringement, and prior knowledge exclusions. Don’t discover gaps when you file a claim.

$2,500 is standard for small firms. Larger companies negotiate higher deductibles to cut premiums. Only do this if you can pay it without draining reserves.

Many carriers offer E&O and cyber together at better rates than buying separately. Bundled coverage also simplifies claims if one incident triggers both policies.

Frequently Asked Questions

Yes. General liability covers bodily injury and property damage. Tech E&O covers claims that you failed to deliver or made a mistake. They’re separate. Buy both.

 They’re the same thing. “Professional indemnity” is the UK/Australia term. “E&O” is the US term.

Yes, but it’s harder and costs more. Large payouts push you to specialty carriers or trigger exclusions. Be honest about history. Hiding prior claims can void coverage.

Usually yes, as a business expense. Ask your accountant. Insurance premiums are typically deductible.

No. One policy covers multiple services: IT consulting, system integration, staff augmentation. If you add a very different service (like hardware), you may need an amendment.

3–7 days for a clean risk with no prior claims. Claims history extends that to 2–3 weeks. Some carriers can bind coverage same-day in emergencies.

You pay legal defense from reserves: $25,000–$100,000+ just to defend. If you lose, you pay the full judgment. E&O insurance is far cheaper than self-insuring.
