The short answer
A certificate of insurance is a one-page summary of the policies you carry, issued by your broker on the standard certificate form and handed to a landlord, customer, or site owner as evidence that coverage exists. It lists the lines, limits, policy numbers, and dates, and it confers no rights on its own. The rights the counterparty actually wants, additional insured status, a waiver of subrogation, primary and non-contributory wording, live in endorsements to the policy, and the certificate only reports whether they exist. When the program already carries what is asked, issuing a certificate is a short broker task.
What a certificate actually is
A certificate of insurance is a one-page summary of your insurance program, produced on the standard certificate form the insurance industry uses. Your broker fills it in from your policies and sends it to whoever asked. It evidences coverage. It does not create coverage, amend a policy, or give the holder any right to be paid, and the form says so in its own disclaimer text.
That distinction is the whole document. A landlord holding your certificate has proof that a general liability policy existed on the date it was issued, at the limits shown, with your company as the named insured. Whether the landlord can claim under that policy depends on an endorsement, and the certificate only reports whether one exists.
The boxes are the same on every certificate, which is why a procurement officer can read one in ten seconds. The table below is what each box means when your machine is the subject.
What each box on the certificate means
| Insured | Your legal entity, spelled the way it appears on the policy. A mismatch with the contract's party name is the most common reason a certificate bounces. |
|---|---|
| Lines and policy numbers | One row per policy: general liability, umbrella, auto, workers' compensation, and a spare row for tech E&O, cyber, or equipment. Each row carries the carrier and the policy number. |
| Limits | Per occurrence, aggregate, and the sublimits the form breaks out. A $1M per occurrence and $2M aggregate general liability policy fills the two boxes a landlord reads first. |
| Dates | Effective and expiration dates for each policy. A certificate is a snapshot; it says nothing about what happens after the expiration date printed on it. |
| Certificate holder | The party the certificate is addressed to. Being the holder gives them a copy and, where the wording allows, notice of cancellation. It does not make them an insured. |
| Description of operations | Free text where the broker writes what the contract requires: the additional insured, the waiver, the primary and non-contributory wording, the project or site. This box is the one to read. |
| Additional insured and waiver checkboxes | Ticked only when a matching endorsement is on the policy. A ticked box with no endorsement behind it is a misstatement, and brokers are careful about it for that reason. |
What the landlord and the customer want
Additional insured status means your liability policy also responds to claims against the counterparty that arise from your work. A waiver of subrogation means your insurer gives up the right to recover from the counterparty what it paid on your claim. Primary and non-contributory wording means your policy pays first, before the counterparty's own policy contributes. Each of these changes who the policy protects or the order in which policies pay, and a change to the policy can only be made by the carrier, in an endorsement. The certificate is written by the broker and cannot do it.
The landlord case is the simplest. A lease usually requires general liability at $1M per occurrence and $2M aggregate, the landlord as additional insured, and the certificate before signature. A general liability policy placed with blanket additional-insured wording turns that into a certificate request your broker completes the same day. A policy without it needs a scheduled endorsement first.
The customer case adds lines. An enterprise customer wants tech E&O and cyber on the certificate alongside general liability, and a site owner hosting your robot wants the additional insured and the waiver to cover the specific premises. Hospitals and utilities push the limits to $5M. The certificate reports all of it, and the endorsements behind it do the work.
What a certificate costs
Certificates are issued at no charge by your broker, in whatever number a year of contracts requires. A company with a dozen pilots on customer sites will hold a dozen certificates, each addressed to a different site owner, all drawn from the same policies.
Endorsements are different. A scheduled additional-insured or waiver endorsement can carry a premium set by the carrier, and a policy placed with blanket wording avoids that charge on every contract that follows. We do not publish a figure, because the price depends on the carrier and on what the endorsement covers. The larger cost is time: a scheduled endorsement waits on the carrier, and a lease or a site visit can wait with it.
For a first-time buyer the placement itself is the expense. The certificate is a byproduct of a policy that exists, and no broker can issue one against a policy that does not.
What to watch for on a certificate
The first hazard is a certificate holder who asks for something the policy does not have. A contract that requires the counterparty as additional insured on your tech E&O, a line where the status is unusual, or a $5M limit on a $1M policy, cannot be satisfied by a certificate. A broker who writes it into the description box anyway has produced a document that misstates the coverage, and that surfaces at claim time.
The second is notice wording. The standard form says notice of cancellation will be delivered in accordance with the policy provisions, and many contracts demand a firm thirty days to the holder. The gap between the two is a contract term you have agreed to and your insurer has not. The fix is a notice endorsement where the carrier offers one, or a contract edit where it does not.
The third is the expiration date. Policies renew annually and pilots run for eighteen months, so a certificate issued at signature lapses mid-contract, and a diligent counterparty tracks it. The fourth is the phrase "as their interest may appear", which asks for a loss-payee position on property or equipment coverage, a different endorsement from additional insured, and one that belongs on the equipment policy following your machine rather than on general liability.
How to get one issued fast
Send the insurance clause to your broker before you sign, with the counterparty's legal name and address as they want it to appear. When the program already carries what the clause asks, the certificate is a short broker task. When the clause needs a scheduled endorsement, add the insurer's turnaround. When you are buying the line for the first time, the placement is the slow part, and a general liability policy for a company putting a machine on a customer's floor takes longer than one for a software company.
We issue certificates from your file and read the clause against the policy before we do. If the clause asks for something the policy cannot give, you hear it before signature, with the price of the endorsement or the wording of the contract edit that closes the gap.

Common questions
How fast can I get a certificate of insurance?
Quickly, when the policy already carries what the counterparty asks. Longer when the request needs a scheduled endorsement from the insurer, and longest when you are buying the line for the first time, because the placement is the slow step.
Does a certificate of insurance mean the counterparty is covered by my policy?
No. The certificate evidences that your policy exists at the limits shown. Whether the counterparty can claim under it depends on an additional insured endorsement to the policy, which the certificate reports but does not create. The policy wording governs at claim time.
What is the difference between a certificate holder and an additional insured?
The certificate holder is the party the document is addressed to; they get a copy and, where the wording allows, notice of cancellation. An additional insured has rights under the policy itself, added by endorsement. A landlord usually wants both.
Our landlord wants a certificate before we sign and we have no insurance yet. What do we do?
Buy general liability now and send the clause with the application. The placement is the slow part, so start it before the lease negotiation ends rather than after. Once the policy binds, the certificate with the landlord as additional insured issues the same day if the policy carries blanket wording.
Can we fill out our own certificate?
No. A certificate is issued by the broker or carrier from the policy records, and a self-produced one is a misrepresentation with real consequences. Ask your broker; it costs nothing and takes hours.
Why does our certificate say notice follows the policy provisions?
Because that is the standard form's wording, and a certificate cannot promise more than the policy does (Oregon Division of Financial Regulation, accessed 2026-09-12). If your contract demands firm notice, the fix is a notice-of-cancellation endorsement where the carrier offers one, or a change to the contract where it does not.
