A Client Asked You for a Certificate of Insurance. Here's What to Do.

The email arrives while you're still picking out the kickoff date: "Can you send over your certificate of insurance before we start?" Your stomach drops a little. You want this client, not to lose them over a form you've never seen. A certificate of insurance (COI) is a free, one-page document that proves you have an active insurance policy. It lists your coverage, your limits, the dates, and your insurer. The client wants it so they know your policy pays if your work causes damage or injury, instead of them paying for it.

A COI proves coverage exists; it isn't the policy

A COI proves you bought and paid for an active policy. It shows who you are, who your insurer is, what you carry, your policy numbers, the start and end dates, and your limits.

Most insurers use the same standard form, the ACORD 25. One page, marked "for information only." The certificate proves coverage exists. It doesn't create coverage. State regulators treat a COI as evidence and nothing more. It can't change what your actual policy provides.

So when a client asks for proof of insurance, they want this one page. Not your full policy. Not a contract.

Why clients ask for a COI

The client wants to know that if something goes wrong on the job, your coverage handles it and not them. That's the whole reason.

It means they treat you like a real business. Half the time the client isn't even the one requiring it. Their lease, their contract, or their vendor rules require a certificate of insurance from everyone they hire.

After thirty years of clean work, an insurance question can feel like an insult. It isn't one. A single accident or lawsuit can shut a small business down. The client is protecting themselves from that. You should be too.

How to get a COI, step by step

You need an active liability policy first. The certificate comes from that policy. Once you're covered, the COI is usually free and quick. Here's the path from zero:

1. Get a liability policy. This is the coverage that pays if your work causes injury or damage. No policy, no real certificate.
2. Request or download the certificate. Most insurers let you pull it online or get it from your agent. Many issue one within 24 hours, often the same day.
3. Send it to the client. Email it over, or have your insurer send it directly. Done.

If a client won't let you start until they have the certificate of insurance, the slow part isn't the paper. It's getting the policy. Once that's done, the certificate is fast.

A COI is free; the policy is what costs money

You don't pay per certificate. You can send as many copies as clients need. What costs money is the policy behind it.

So if you already have liability coverage, sending a COI costs you zero. If you don't have coverage yet, you pay for the policy, and the certificate is free.

Do I really need insurance for one small gig?

If a client requires a COI, then yes. No proof, no work, in most cases. The ask is usually reasonable. A $1 million general or professional liability limit is what most clients request, and it's the limit most freelancers carry. It sounds enormous. It's the normal floor.

And you don't have to lock into a year of coverage for one project. Solo-friendly policies exist. You can get covered for the work in front of you and send the certificate the same day.

"Certificate holder" vs. "additional insured"

These sound alike and mean very different things.

A certificate holder is the party who receives a copy of your COI for their records. They get the paper. Your policy doesn't change.

An additional insured is a client who gets added to your policy, so your coverage extends to them for claims tied to your work. This happens through an endorsement, a formal change that names them on the policy. It's a bigger ask. It can take a little time and carry a small extra cost.

If a client just wants a COI, you're almost always being named as a certificate holder. If the email says "name us as additional insured," that's the larger request. Still common, still legitimate. Worth checking with whoever handles your policy so it's set up right.
