Professional Liability Insurance
Professional liability (errors & omissions) covers claims that your professional work was negligent, late, or failed to deliver what was promised — the core 'failure to perform' exposure every software consultancy faces.
Professional Liability for Python Developers
Professional liability — errors & omissions — responds when a client alleges your work was negligent, defective, incomplete, or didn't deliver the promised result. For a Python or data consultancy, that's the project that ships late and costs the client a launch, the deliverable that doesn't meet spec, the recommendation that turns out wrong, or the engagement where the client claims you failed to exercise reasonable professional skill.
These claims are about economic loss, not bodily injury or property damage — which is exactly why general liability won't touch them. Even when you've done nothing wrong, a dissatisfied client can file suit, and the cost of defending a professional-negligence claim alone can be substantial. Professional liability funds that defense and pays covered damages.
Built Into Tech E&O — or Standalone
For most software firms, professional liability is delivered as part of a technology E&O policy alongside cyber. Pure consultancies that don't build or host software sometimes carry standalone professional liability (often called miscellaneous professional liability). We structure it the right way for your work — and make sure the limits satisfy the indemnification and insurance clauses in your client contracts (MSAs).
What's Covered
Frequently Asked Questions
Yes — solo developers face the same failure-to-deliver and negligence claims as larger shops, and many clients require proof of E&O before signing. A single disputed project can generate a claim that dwarfs years of premium. It's the most important coverage for an independent developer.
Professional liability is one half of a technology E&O policy; the other half is cyber liability. For software firms we usually write them together as tech E&O. Pure consulting firms can carry standalone professional liability if they don't build or host software.
