Why Clients Ask for a Certificate of Insurance (and How to Get One Fast)

What a certificate of insurance actually is

A certificate of insurance, often shortened to COI, is a document summarizing your active coverage — type, limits, and effective dates. It's proof that you have insurance, used so clients or venues don't have to take your word for it.

Why bigger clients require it

Larger companies, venues, and platforms often require a COI before signing a contract because it protects them too — if something goes wrong during your work, they want documented proof you have coverage in place, not just a verbal assurance.

When you'll typically be asked for one

This request tends to show up at predictable points in freelance and small business work.

• Before signing a contract with a larger company or agency
• Before renting event space or a commercial venue
• When working on-site at a client's property
• When applying for certain business licenses or permits

How fast you can actually get one

Once your policy is active, most insurers can generate a certificate of insurance same-day, often instantly through an online dashboard — it's typically one of the simpler requests in the entire process.

What to double check before sending it

Make sure the certificate lists the correct coverage limits the client requested, and that the client is named as an 'additional insured' if that's specifically what they asked for — a generic certificate without that detail can sometimes be rejected.
