You signed the contract. You have insurance. You assume you’re covered.
Then a claim gets filed, and your insurance broker delivers news you didn’t expect: your policy doesn’t match what the contract requires.
This happens more often than most business owners realize. And the moment you discover it is the worst possible moment to discover it.
Here’s what commonly happens at this stage of growth.
What a Certificate of Insurance Actually Is
A certificate of insurance (COI) is a one-page summary document your insurance carrier issues. It shows your policy type, coverage limits, effective dates, and the insurer’s name.
When a vendor, customer, or commercial landlord asks to “see your insurance,” this is what you send them.
But a COI is not a contract. It’s a snapshot. It doesn’t modify your underlying policy, and it doesn’t guarantee that your coverage actually meets what the other party is asking for.
That distinction matters enormously.
Why Contracts Specify Coverage Requirements
When a customer or vendor requires specific insurance in your contract, they’re not just asking whether you have insurance. They’re asking whether you have enough of the right kind.
Common requirements in vendor and customer agreements include:
- Minimum coverage limits—for example, $1 million per occurrence and $2 million aggregate for commercial general liability
- Additional insured status—this is where things get complicated
- Waiver of subrogation—your insurer agrees not to pursue the other party if they pay a claim
- Primary and non-contributory language—your policy pays first, before theirs
The additional insured requirement deserves special attention.
When a contract requires you to name the other party as an additional insured, you’re agreeing that your policy will extend coverage to them for certain claims arising from your work.
This isn’t automatic. It requires a specific endorsement on your policy, and your insurer has to actually issue it. [ADDED: Endorsement types vary—some are blanket, others are project-specific—and the scope of coverage can differ significantly.]
Your certificate of insurance might show the other company’s name in the additional insured field. But if the endorsement isn’t on the underlying policy, that line on the COI is essentially meaningless when a claim is filed.
Where Growing Companies Get Caught
Imagine this: a 30-person company lands a significant services contract with a large enterprise customer. The customer’s legal team sends over their standard vendor agreement. It includes insurance requirements—$2 million per occurrence, additional insured status, waiver of subrogation, primary and non-contributory.
The company’s operations lead reviews the contract, sees the insurance section, and thinks: “We have insurance. We’ll send them a COI.” They sign.
Eighteen months later, there’s an incident at the customer’s facility related to the vendor’s work. A claim gets filed. The customer’s risk team calls their broker. The vendor’s broker gets involved.
And that’s when everyone discovers that the vendor’s policy only carries $1 million per occurrence, the additional insured endorsement was never added, and the waiver of subrogation wasn’t included.
The customer now has a coveragegap. The vendor is potentially on the hook for amounts their policy doesn’t cover. And the contract they signed says they were supposed to have this coverage in place from day one.
This scenario is common for companies growing quickly and closing contracts without comparing actual policy terms to contractual requirements.
What Contract Review Should Catch
When reviewing vendor or customer agreements, the insurance section is one of the first places to examine. Not because it’s the most complex clause in the contract, but because it’s one of the most commonly mismatched.
The review process involves two parallel checks. First, what does the contract require? Second, what does your current policy actually provide?
If those two things don’t match, flag it before signing—not after.
The fix is usually straightforward. Your broker can often add an additional insured endorsement, adjust coverage limits, or add specific language to your policy. The cost is typically modest. Some insurers may require a modest premium increase for primary and non-contributory language, particularly on larger contracts. But it has to happen before you sign, not after a claim reveals the gap.
The other thing worth noting: some contracts include language requiring you to notify the other party if your coverage lapses or changes. If you switch insurers mid-contract and forget to update the additional insured endorsement, you may be in breach even if you still have active coverage.
The Practical Takeaway
Insurance requirements in contracts aren’t boilerplate. They’re specific commitments about what your policy will cover and who it will protect.
Before you sign any agreement that includes insurance requirements, run those requirements against your actual policy—not just your certificate.
A COI tells the other party you have insurance. Your policy determines whether you actually have what you promised. Those are two very different things.
