Certificate Of Insurance For Business

If you’re in construction, real estate, or an industry where claims and lawsuits are highly possible due to the nature of work being done, one of your priorities must be to make sure that the people working with you are maintaining an adequate level of insurance coverage.

That can mean many things to you, but a surefire one is this: you’d better start getting comfortable with the concept of insurance certificates. Don’t fret, however, if you’re not sure what those are yet. This resource is the one you’ve been looking for.

In this article, we’ll cover the major need-to-knows and answer common questions regarding certificates of insurance, including:

  • What does a certificate of insurance mean in business?
  • When do you need a certificate of insurance from a vendor?
  • What must be included in a certificate of insurance?
  • How fast can I get a certificate of insurance (COI)?
  • What do I do if I need help managing my COIs?

Ready to master the basics of COI management and get your compliance on track? Let’s dive in.

What Does Certificate of Insurance Mean in Business?

Certificates of insurance have become a big deal in the business world because they’re related to contractual partnerships, especially between two businesses or between a business and a third party, vendor, or contractor.

To start, let’s discuss the concept of insurance coverage for businesses.

Business insurance provides a company with protection. In exchange for paying premiums to an insurer, the insurance company agrees to cover any financial losses of that business if a covered situation happens. For instance, a contractor might get general liability insurance, an insurance policy that provides coverage in the case of property damage or physical injury, since they would otherwise be held financially responsible for common site accidents.

But anyone can say that they have insurance coverage. To prove it, businesses rely on the use of certificates of insurance.

Typically no longer than a page, certificates of insurance, or COIs, are documents that provide a summary of someone’s business insurance. They’re a quick way to prove that someone has the policy in place that they say they do. This is important because if a worker doesn’t have the correct coverage, it could be your business held accountable for paying financial losses due to damages that happen on the job.

COIs are essentially insurance policy shortcuts. So, instead of a contractor providing you (and other prospective clients) with a dense, multi-page policy document, they can instead hand over a summarized certificate that hits the key points of their coverage. It’s a win-win for everyone.

Once you verify that the COI is accurate and up-to-date and that their coverage meets your requirements for the project and timespan, you can have peace of mind as you begin your business partnership.

When Do You Need a Certificate of Insurance From a Vendor?

There are numerous situations where you could need a certificate of insurance from a vendor. Essentially, any time you’re working with someone on a job where accidents or incidents could arise, you should obtain a certificate of insurance from the entity you’re hiring – just in case.

Here are a few examples of situations where a company might require a COI from a vendor:

  • Hiring a contractor. This is a really common case where COIs are necessary. If you’re hiring a contractor or subcontractor, you’ll need to request a COI from them to ensure that they have appropriate insurance coverage in case of any accidents that could occur during the span of work.
  • Hiring a supplier. If you’re purchasing goods or materials for your business from a supplier, it makes sense to request a COI from them. This will help you confirm that they have coverage in place to cover damages in the case of any accidents that could happen during the transportation and delivery of the purchased goods, or while they’re on your property.
  • Hosting an event. When hosting a business event, you’ll want to request a COI from all vendors and service providers involved to protect you from accidents or damages that could happen during the event.

It’s common in many of these types of instances for the hirer of the third party to require a COI from the third party as a condition of doing business with them. Most vendors and contractors that you work with will know about the standard requirements for their industry and be prepared to procure a COI to provide to you as proof of their coverage ahead of beginning their work.

What Must Be Included in a Certificate of Insurance?

While certificates of insurance vary based on the type of policy they’re providing evidence of, there are a few items that must be included in every certificate of insurance.

Here are some of the details you’re likely to find on any given insurance certificate:  

  • The insurance company’s name. When discussing someone’s insurance coverage, it’s pretty important to know who is providing the protection. The insurance company is the entity that will be creating the actual contract, so this piece should not be an issue.
  • The policyholder’s name. The third party you’re working with – the one you are verifying coverage for – must provide their information on the certificate of insurance in order to indicate who is being covered.
  • The policy number. This references the actual insurance policy with a unique numerical identifier.
  • The type of coverage. It’s important for you, as the certificate requester, to clearly state the type of protections your third party needs to have in place before beginning work with you. Some examples of common coverage types are general liability insurance and workers’ compensation.
  • The policy limits. These specify the maximum amount of coverage provided by the policy. This is another key piece to pay attention to, as policy limits will give you an idea of the amount of coverage the third party has in case of any liability claims or damages that could arise during the course of your business relationship. You should ensure that the policy limits are adequate for the level of risk associated with the work they will perform.
  • The effective dates of coverage. These outline the time period that the policy is active. It’s important that you confirm that the policy will be active during the time that the work will be performed and that all third parties involved maintain coverage for at least the entire duration in which they’re working with you. If that duration is fairly long, it makes sense to verify active coverage throughout.
  • Additional information needed, such as additional insureds or other endorsements. In special cases, other information will be included in a COI. For instance, if their policy covers any additional parties, an additional insured endorsement would be reflected on the certificate. In fact, if you aren’t named the additoinal insured on the COI, you aren’t covered should a claim roll up to you.
  • Insurance agent contact information. Certificates must also relay the contact information of the specific insurance agent or broker providing coverage to the third party.
  • Certificate holder name. Your name (or business name) will be printed on the document under the Certificate Holder section. You’ll also likely be notified about things like coverage changes, annual renewal, or cancellation of the policy.

How Fast Can I Get a COI?

The rate at which you can obtain a COI from a vendor depends on a few factors, some of which are, unfortunately, out of your control. As the entity hiring the third party and therefore needing to verify someone else’s insurance coverage, you won’t be the one headed to an insurance office to obtain a COI.

Instead, as the requester of the COI, you will become the certificate holder on the document. All you need to do in the case that you need to obtain a certificate from someone is to make a formal request in person or in writing to the third party you need to verify coverage for. You’ll provide them with information such as the coverage type you need proof of and any specific requirements you have, such as a minimum length of coverage.

It typically takes 1–2 business days for an insurance company to generate a COI once the initial request has been made from the insured (the third party you are hiring). However, it can take up to a few weeks to generate, depending on the insurance company’s standards and the complexity of the coverage, as well as if there are any errors or omissions that could slow down the process.
