What this means
Professional liability limits are usually shown as per-claim and aggregate limits. A contract may require $1M per claim, $2M aggregate, or higher limits depending on customer size, industry, and perceived risk.
Do not compare policies by premium alone; limit structure, defense costs, deductible, and exclusions can matter more than small price differences.
When it shows up
This usually appears when a client could claim your advice, software, implementation, service, or deliverable caused financial harm.
In practice, the requirement is rarely only about buying insurance. It is also about showing that you understand the client's risk concern, can produce the right evidence, and know which details belong with a broker, IT/security contact, operations owner, or legal reviewer before you sign.
What to look for in the contract
Look for the required limit, whether the wording says professional liability, E&O, or technology E&O, and whether the policy must cover your exact services.
Exact policy names or phrases, such as cyber liability, technology E&O, or professional liability.
Per-claim, aggregate, sublimit, deductible, and any contract-specific amount.
Certificate holder, due date, endorsement wording, and delivery instructions.
How to use this guide
Treat this page as preparation for a more precise conversation. Start with the checklist, gather the evidence you already have, and split unanswered items into coverage questions for a broker and readiness questions for IT, security, or operations.
Checklist
- Identify per-claim and aggregate requirements.
- Check whether defense costs erode the limit.
- Compare deductible options.
- Ask your broker to confirm whether the certificate can display the requested limits.
Who should help with what
This is mostly a broker handoff, but the broker needs an accurate description of the work from the people who deliver it.
Ask a broker to confirm whether the policy covers your actual services, deliverables, advice, implementation, support, and required limits.
Ask an operations, delivery, or technical lead to describe the work you perform, where client systems or data are involved, and what evidence supports the service description.
Common mistake to avoid
The common mistake is buying generic professional liability without checking whether the professional services definition fits the work in the contract.
Questions for the right specialist
Coverage questions
- How should I evaluate a $1M/$1M option against this client requirement?
- What is the cost difference for $2M aggregate?
- Are defense costs inside or outside the limit?
Readiness questions
- How should we describe the actual services, deliverables, implementation work, or support being provided?
- Do we access client systems, store client data, or operate software that could create cyber or technology E&O concerns?
- Who can confirm whether subcontractors, freelancers, or vendors are part of the work?
Build your packet
If this requirement is tied to a real client contract, use the CoverReady checklist to turn the wording into a readiness packet: coverage questions for your broker, technical evidence for IT/security, certificate needs, and items to clarify before making commitments to the client.
