Why Do Clients Ask for a COI? A Certificate of Insurance Guide for Businesses

A client asks for a COI before allowing you to start a job. A commercial landlord requests one before signing a lease. A general contractor needs it before letting your team enter a job site.

These situations often create urgency, especially when a project, contract, delivery, or lease depends on providing the document quickly.

A COI, or Certificate of Insurance, does not replace your insurance policy. However, it can be the document that helps your business move forward with a new opportunity. It provides a concise summary of your active insurance coverage so that clients, landlords, contractors, and business partners can confirm that your company carries the insurance required for the work.

This guide explains what a COI is, why clients request one, what information it may include, and how to avoid delays when a certificate is needed.

A Certificate of Insurance is evidence of insurance at the time it is issued. It does not create coverage, change policy terms, expand limits, or replace the insurance policy and applicable endorsements. Actual coverage depends on the policy, endorsements, exclusions, conditions, and facts of a specific claim.

What Is a COI?

A Certificate of Insurance (COI) is a document that summarizes important information about a business insurance policy. It is commonly requested by clients, commercial property owners, general contractors, event venues, and other parties before they agree to work with a business.

A COI may show:

• The name of the insured business or professional.

• The insurance carrier.

• The types of insurance coverage in force.

• Policy numbers.

• Effective and expiration dates.

• Coverage limits.

• The certificate holder’s name and address.

• Certain contract-related requirements, when properly requested and approved.

For example, a cleaning company working in an office building may provide a COI showing its general liability insurance. The property manager or client can quickly verify that the company has active coverage before allowing employees to access the property.

The certificate is useful because it provides a high-level confirmation of insurance. But it is important to remember that the COI itself is not the insurance contract.

What Does a Certificate of Insurance Prove?

A Certificate of Insurance can help demonstrate that a business had certain insurance coverage in effect on the date the certificate was issued.

It may confirm that the business has policies such as:

• General liability insurance.

• Commercial auto insurance.

• Workers’ compensation insurance.

• Professional liability insurance.

• Commercial umbrella insurance.

• Cyber liability insurance.

• Liquor liability insurance.

• Other coverage required by a client or contract.

However, a COI does not guarantee that every loss will be covered. It does not override exclusions, add coverage that is not included in the policy, or change the policy’s limits.

If a claim occurs, the insurer will evaluate it based on the policy language, applicable endorsements, the facts of the incident, and other relevant information.

Why Do Clients Ask for a COI?

Clients usually ask for a COI to reduce their business risk before hiring a vendor, contractor, service provider, tenant, or subcontractor.

The question is often phrased as, “Why do insurance companies need a COI?” In most cases, it is not the insurance carrier requesting the document. Instead, the request comes from the party that wants proof that your business has the insurance required for the job or agreement.

A COI helps the requesting party verify that a business is not taking on work without a basic level of financial protection.

For example, a client may want to know that:

• A contractor has liability insurance before working at a property.

• A delivery company has commercial auto insurance.

• A business with employees carries workers’ compensation, when required.

• A vendor’s coverage meets the insurance requirements in a contract.

• A tenant has the coverage required under a commercial lease.

If a vendor causes property damage, bodily injury, or another loss during the course of work, the client wants to know that the vendor has insurance that may respond, subject to policy terms and limits.

Common Situations Where a COI Is Required

A Certificate of Insurance is common in many industries. Your business may need a COI when you are:

• Starting work for a new client.

• Signing a commercial lease.

• Working as a subcontractor.

• Entering a construction site.

• Providing cleaning or maintenance services.

• Delivering products or equipment.

• Operating commercial vehicles.

• Hosting or participating in an event.

• Working for a property manager.

• Providing professional services.

• Bidding on a commercial project.

• Working with a general contractor.

• Renting equipment or a commercial space.

A business without a valid COI may lose a contract opportunity, even if it has strong references, competitive pricing, and relevant experience.

How a COI Helps Meet Contract Requirements

Many contracts require specific insurance coverage and limits. A commercial landlord may require general liability coverage with a certain limit. A general contractor may require general liability, workers’ compensation, commercial auto insurance, and additional insured status.

An event organizer may request general liability insurance and, depending on the activity, liquor liability coverage.

A COI can help confirm that the required policies are active. But not every certificate will automatically meet a client’s requirements.

The requesting party may require:

• Specific liability limits.

• A specific certificate holder name and address.

• A particular project or location.

• Additional insured status.

• A waiver of subrogation.

• Primary and non-contributory wording.

• Proof of workers’ compensation.

• Proof of commercial auto coverage.

• A commercial umbrella policy.

• Advance notice requirements, where available and permitted.

Each requirement should be reviewed against the actual policy before the COI is issued.

What Types of Coverage May Appear on a COI?

The insurance shown on a COI depends on the business, its operations, and the requirements of the contract.

General Liability Insurance

General liability insurance is one of the most common coverages shown on a COI. It may help protect a business against certain third-party claims involving bodily injury, property damage, and personal or advertising injury, subject to policy terms.

For example, if a contractor accidentally damages a client’s property while performing covered work, general liability insurance may respond within the policy’s limits and conditions.

Commercial Auto Insurance

If your business uses vehicles for deliveries, service calls, transporting equipment, employee travel, or hauling materials, a client may request proof of commercial auto insurance.

This can be especially relevant for businesses that use:

• Cargo vans.

• Work trucks.

• Box trucks.

• Dump trucks.

• Pickup trucks.

• Trailers.

• Delivery vehicles.

• Company-owned cars.

A personal auto policy may not be designed for regular business use. It is important to accurately disclose how vehicles are used in your business.

Workers’ Compensation Insurance

Businesses with employees may be required to carry workers’ compensation insurance, depending on state law and the nature of their operations.

Workers’ compensation may help provide benefits for covered work-related injuries or illnesses. Contractors and commercial clients frequently request proof of this coverage before allowing a vendor or subcontractor to begin work.

Professional Liability Insurance

Businesses that provide professional advice or specialized services may be asked to show professional liability insurance, also called errors and omissions insurance in some industries.

This coverage may be relevant for consultants, technology providers, designers, accountants, real estate professionals, and other service-based businesses, depending on the work being performed.

Commercial Umbrella Insurance

A commercial umbrella policy may provide additional liability limits above certain underlying policies, subject to policy terms. It may be requested for larger projects, high-value properties, public-facing businesses, or contracts with higher insurance requirements.

Specialized Business Insurance

Depending on your business, a client may also request proof of coverage such as:

• Cyber liability insurance.

• Employment practices liability insurance.

• Liquor liability insurance.

• Pollution liability insurance.

• Inland marine coverage for tools and equipment.

• Cargo insurance.

• Commercial property insurance.

Not every business needs every type of coverage. The right insurance program depends on your services, contracts, property, employees, vehicles, customers, and overall risk exposure.

Additional Insured: What Does It Mean?

An additional insured is a person or organization that may receive certain protections under another company’s insurance policy, usually in connection with a specific contract or job.

For example, a property owner may request to be added as an additional insured on a contractor’s general liability policy while the contractor performs work at the property.

Additional insured status does not mean the other party owns the policy or has unlimited coverage for every situation. The protection is generally limited by the policy terms, the endorsement, and the relationship or project described in the contract.

If your client requires additional insured status, it may need to be added through a policy endorsement. Simply listing wording on a COI does not create additional insured coverage if the policy does not support it.

What Is a Waiver of Subrogation?

A waiver of subrogation is a contractual insurance requirement that can limit an insurer’s right to seek recovery from another party after paying a covered loss.

This requirement is often found in construction contracts, commercial leases, vendor agreements, and service contracts.

Like additional insured status, a waiver of subrogation may require a policy endorsement. It should never be assumed to apply merely because it is mentioned in a certificate or contract.

What Does Primary and Non-Contributory Mean?

The phrase primary and non-contributory may appear in insurance requirements. In general, it addresses the order in which insurance policies may respond when more than one policy could potentially apply to a claim.

These requirements can be complex and may require a specific endorsement. A certificate should only reflect this wording when it is supported by the insurance policy and applicable endorsements.

How to Request a COI Without Delaying Your Project

The fastest way to get an accurate Certificate of Insurance is to provide your insurance agency with the full insurance requirement from the client or contract.

Do not send only a short text message, a partial screenshot, or an incomplete request. Instead, share the insurance section of the contract whenever possible.

That section may include:

• Required coverage types.

• Minimum liability limits.

• Additional insured requirements.

• Waiver of subrogation requirements.

• Primary and non-contributory wording.

• Required forms or endorsements.

• Certificate holder information.

• Required job-site or project details.

• Deadlines for submitting the COI.

Your agency can then review whether your current policy meets the requirements.

If your existing insurance is sufficient, the COI may be issued with the correct information. If you need an endorsement, higher limits, or additional coverage, the policy may need to be updated first. Timing and cost can vary based on the insurer, coverage type, contract requirements, and business operations.

Best practice: request the COI early

Do not wait until the day before a project begins.

Request the COI when you sign the contract—or even while the contract is being negotiated. This creates time to address insurance requirements that are not already included in your policy.

For businesses that work with repeat clients, keeping a list of frequent certificate holders and their requirements can also help speed up future requests.

Common COI Mistakes That Can Cause Rejection

A COI can be rejected if the information is incomplete, inaccurate, or does not meet the contract’s requirements.

Common mistakes include:

Expired or Soon-to-Expire Coverage

Clients may reject a COI if the policy has expired or is close to expiration. Keep your policies active and review renewal dates before starting a major project.

Incorrect Legal Business Name

The insured name on the COI should match the legal name required by the contract. A mismatch between your business name, DBA, LLC, or corporation name can delay approval.

Limits That Are Too Low

A certificate may be rejected if the policy limits shown do not meet the minimum limits listed in the contract.

Missing Required Coverage

A client may require commercial auto, workers’ compensation, umbrella coverage, or another policy that is not included in your current insurance program.

Confusing COI Wording With Actual Coverage

A certificate cannot provide coverage that is not included in the policy. If a client requires additional insured status, waiver of subrogation, or primary and non-contributory wording, the agency should confirm that the appropriate endorsement is in place.

Waiting Until the Last Minute

Late COI requests often lead to project delays. Give your agency enough time to review contract requirements and obtain endorsements when needed.

When Should You Review Your Insurance Before Requesting a COI?

Review your business insurance before you:

• Sign a new client contract.

• Start a larger project.

• Begin working with a general contractor.

• Add employees.

• Purchase a business vehicle.

• Add a trailer or equipment.

• Expand into another state.

• Change the services your business provides.

• Enter a commercial lease.

• Increase annual revenue.

• Work on higher-value properties.

• Take on more subcontractors.

A business that started with small jobs may need different coverage as it expands into commercial projects, new locations, larger contracts, or more complex operations.
