A certificate of insurance (COI) is a vital document for any small business. You'll likely encounter requests for a COI when starting new projects or signing lease agreements. Understanding what a COI is and how it works can save you time and prevent delays.

This guide will explain the purpose of a COI. We'll cover its key sections and how to ensure your certificate meets specific requirements.

What is a COI and why do I need one?

A COI is an official document issued by your insurance company or agent. It summarizes your current insurance coverage. Think of it as a snapshot of your policies. It provides proof of insurance for business without revealing sensitive policy details.

So, what is a COI and why do I need one? You need a COI because other parties often require proof that your business is insured. This protects them if an accident or claim occurs involving your work or property. For example, a client hiring you for a project wants to know you have liability coverage. A landlord needs assurance that their building is protected if something happens on your leased premises.

Without a valid COI, you might not be able to:

  • Sign new client contracts.
  • Lease office space or equipment.
  • Obtain permits for certain jobs.
  • Participate in some events or trade shows.

Key Sections of Your Certificate of Insurance

A standard COI, often an ACORD form, contains several important sections. Knowing what each part means helps you understand your coverage.

1. Producer Information

This section lists your insurance agent or broker's contact details. It includes their name, address, and phone number. This is who you contact for questions or changes.

2. Insured Information

This is your business's legal name and address. Make sure this information is always accurate.

3. Policy Information

This area details your specific insurance policies. It typically includes:

  • Policy Type: Such as General Liability, Commercial Auto, Workers' Compensation, or Professional Liability.
  • Policy Number: A unique identifier for each policy.
  • Effective Dates: The start and end dates of your coverage period.
  • Limits: The maximum amount your insurer will pay for a covered claim.
  • Deductibles: The amount you must pay out-of-pocket before your insurance kicks in.

Some policies, like Employment Practices Liability Insurance (EPLI), might also be listed here if you carry them. EPLI covers claims related to wrongful termination, discrimination, or harassment. You can learn more about this type of coverage from resources like the Triple-I employment practices liability insurance overview.

4. Certificate Holder

This is the party requesting the COI. It could be a client, landlord, or general contractor. Their name and address will be listed here.

5. Additional Insureds and Special Provisions

This section is crucial for many business relationships. An "additional insured" is a person or organization added to your policy. This gives them coverage under your policy in specific situations. For instance, a client might require you to list them as an additional insured on your General Liability policy. This protects them if they are sued due to your work.

Special provisions might also include a "waiver of subrogation." This means your insurer cannot seek reimbursement from the certificate holder if they are at fault for a loss.

6. Cancellation Clause

This clause states how much notice your insurer will provide before canceling your policy. This is important for the certificate holder. It ensures they are informed if your coverage lapses.

How to Read a COI

Learning how to read a COI is essential for any small business owner. When you receive a COI, take a moment to review it carefully.

Here's what to check:

  1. Your Business Name: Does it exactly match your legal business name?
  2. Policy Dates: Are the "Effective Date" and "Expiration Date" current? Your coverage must be active for the period required.
  3. Required Coverage Types: Does the COI show all the specific types of insurance requested? For example, if a client asks for General Liability and Commercial Auto, ensure both are listed.
  4. Coverage Limits: Do the limits meet the minimums specified by the requesting party? Many contracts will state required liability limits, such as $1 million per occurrence.
  5. Certificate Holder: Is the requesting party's name and address correct?
  6. Additional Insureds/Waiver of Subrogation: If required, are these endorsements clearly noted? Look for specific language or policy forms referenced.
  7. Cancellation Notice: Does the cancellation clause meet any contractual requirements?

If anything looks incorrect or incomplete, contact your insurance agent immediately.
