Small Business Proof of Insurance Checklist
Use this small business proof of insurance checklist to review a COI, check policy details, and discuss contract requirements with your agent.

Small business proof of insurance often takes the form of a Certificate of Insurance (COI). It summarizes policy types, limits, and dates as reported when issued. Clients, landlords, and partners may request one before a job or lease starts. A COI does not create coverage or prove that every contract requirement is met. Use this Small Business Proof of Insurance Checklist to review the details, request relevant endorsements, and raise gaps with your licensed agent before relying on the document.
Small Business Proof of Insurance: What It Is
A Certificate of Insurance (COI) is a summary issued by your insurance company or agent. It describes the policies shown on the document. The policy and its endorsements determine which claims may be covered. Many business deals require this proof. Businesses like contractors, consultants, and event planners often need to provide COIs.
You might need to show a COI for many reasons:
- Client Contracts: Many clients request evidence of the coverage and limits they require. The certificate alone does not establish whether a claim is covered.
- Lease Agreements: Landlords often ask for a COI. It shows liability coverage for your space.
- Vendor Requirements: Your vendors might need your COI. You should also ask for theirs.
- Regulatory Rules: Some industries need specific insurance. Check which evidence the regulator accepts; a COI alone may not meet its requirements.
- Risk Management: Having COIs for partners helps you manage your own business risks.
A COI is not your full insurance policy. It is a snapshot. It gives a quick look at your insurance at one time. It does not change your actual coverage.
Your Small Business Proof of Insurance Checklist
When you receive a COI, check it carefully. This checklist helps you confirm all details are correct. Compare it with the requirements you received. Confirm the issue date and contact the issuing agent through independently verified details if anything is unclear.
Key Details to Verify on a COI
Use these steps to check any COI you receive or provide:
- Insured's Name: Does the name match the business you are working with? Or your own business name if you are providing it?
- Certificate Holder: If you are receiving the COI, is your business name listed here? This shows who requested the proof.
- Policy Dates: Do the listed start and end dates cover the planned work? Dates alone do not rule out later cancellation; confirm current status with the issuer.
- Coverage Types: Does the COI list the specific types of insurance required? Examples include General Liability, Workers' Compensation, or Professional Liability.
- Coverage Limits: Do the limits meet your contract needs? For example, a contract might request $1,000,000 per occurrence and $2,000,000 general aggregate. These are examples, not universal requirements.
- Additional Insured: If required, ask for the relevant policy provision or endorsement and check its conditions. Being a certificate holder does not by itself make you an additional insured.
- Waiver of Subrogation: If required, ask for the policy provision that limits the insurer’s recovery rights against the specified party. Its scope depends on the wording.
- Cancellation Notice: Check whether the policy, endorsement, or applicable law grants you notice rights. Certificate wording alone cannot create them.
Understanding Policy Limits and Exclusions
A COI gives you a summary. It does not show everything about a policy. It is important to know its limits. The full policy document contains all the details.
Common COI Limitations
- Exclusions: A COI does not list policy exclusions. These are things your policy does not cover. If you have concerns, ask the insured party for details from their full policy. For example, some policies exclude certain types of work or materials.
- Limits: The COI shows coverage limits. Payment remains subject to policy terms, exclusions, deductibles, and any applicable remaining aggregate. Make sure these limits are enough for your risk. A low limit might not cover a large claim.
- Not a Guarantee: A COI reports policy information at issuance. It is not a promise of coverage for a claim. The actual policy wording controls coverage.
- Policy Changes: A COI is a snapshot in time. The policy details can change. Always ask for an updated COI if you have doubts.
For a broader understanding of business insurance basics, refer to the SBA guide to business insurance. This can help you understand what different policies cover.
The Texas Department of Insurance certificate FAQ explains these limits for Texas risks, including notice rights and additional-insured wording. Requirements vary by state. Ask your agent to check the rules that apply to your work.
How to Get and Provide a COI
Managing Certificates of Insurance is a key part of business operations. Follow these steps whether you need to provide one or ask for one.
To Request a COI from another business:
- Know Your Needs: Check your contract or lease. What types of coverage do you need? What limits? Are "Additional Insured" or "Waiver of Subrogation" clauses required?
- Make a Clear Request: Send your needs in writing. Include your business name and address. State why you need the COI.
- Review Carefully: Once you get the COI, use the checklist above. Compare it with your requirements. Ask the agent to correct errors or assess any coverage changes needed; revised certificate wording cannot expand the policy.
To Provide a COI for your business:
- Contact Your Agent: Reach out to your insurance agent or broker.
- Give All Details: Provide them with:
- Your business name and policy numbers.
- The name and address of the party needing the COI (the Certificate Holder).
- Any specific wording for additional insured status or waiver of subrogation.
- Specify Delivery: Tell your agent how and where to send the COI.
- Keep Records: Save a copy of every COI you provide. Track expiration dates. Ask for updated COIs before old ones expire. This helps avoid gaps in coverage proof.

Next Steps for Your Business Insurance
Before you buy new insurance or renew existing policies, take these steps. They help ensure you get the right coverage.
- Review Your Needs: Has your business changed? Do you have new clients, contracts, or risks? Your insurance should match your current operations.
- Understand Your Policies: Read your policy documents. Know what is covered and what is not.
- Prepare Questions: Write down any questions you have for your agent. This includes questions about specific scenarios.
- Talk to a Licensed Agent: An agent can help you understand complex terms. They can explain how different policies work together. They can also help you compare options. A licensed agent can confirm how carrier rules apply to your business. Ask them to explain exclusions, available options, and where your contract requirements may exceed the policy. For businesses operating in real estate, understanding specific market nuances is key. You can explore the U.S. Real Estate Insurance Market Map for more context.
