Client asks for a COI and you freeze up. You are not alone. This happens to freelancers, contractors, and small-business owners every day. The good news: it is not complicated. A Certificate of Insurance (COI) is just a one-page proof that you carry active coverage. You do not need a lawyer. You do not need to buy a new policy. In most cases, you can have one in hand within minutes.
Where You Stand: When a Client Asks for a COI
A COI is not a policy. It is a snapshot. The standard form is the ACORD 25, used across all 50 states. It lists your policy types, coverage limits, policy numbers, and dates. It also names the person or company requesting it. When a client asks for a COI, they want proof you will not leave them holding the bill if something goes wrong on their property or project.
This request is standard business. General contractors require COIs from every sub. Commercial landlords require them before signing a lease. Corporate clients require them before approving a vendor. According to the Insurance Information Institute, the COI is the most common insurance document exchanged between businesses. However, the specific coverage types and limits your client demands will vary by trade and state.
| Trade | Typical GL Limits Requested | Median Annual GL Premium | Extra Coverages Often Required |
|---|---|---|---|
| House Cleaning | $1M / $2M | $590/yr (~$49/mo) | Workers comp, bonding |
| IT Consulting | $1M / $2M | $324/yr (~$27/mo) | Professional liability (E&O) |
| Landscaping | $1M / $2M | $1,000/yr (~$83/mo) | Commercial auto, workers comp |
| General Contractor | $2M / $4M | $3,000–$5,000/yr | Workers comp, umbrella, builder’s risk |
| Photography | $1M / $2M | $275/yr (~$23/mo) | Equipment floater, E&O |
If you already carry general liability insurance, you likely have everything you need. The COI simply proves it. If you do not have a policy yet, a client asks for a COI is your signal to get one — fast.
What to Do First (Step by Step)
Step 1: Read the client’s requirements carefully. Many clients send a written list. Look for specific coverage types, minimum limits, and whether they want to be named as an “additional insured.” Certificate holder and additional insured are not the same thing. A certificate holder simply gets notified if your policy cancels. An additional insured is actually protected under your policy. When a client asks for a COI with additional insured status, your agent must add an endorsement to your policy. That endorsement typically costs $20 to $75.
Step 2: Contact your agent or log into your portal. Most insurers now offer self-service COI portals. You can generate a basic certificate in under 60 seconds. If the client asks for a COI with special requirements — like a waiver of subrogation or specific additional insured language — call your agent directly. Typical turnaround is 24 to 48 business hours for anything beyond a basic certificate.
Step 3: Review the COI before sending it. Check that your legal business name is correct. Verify the policy dates cover the project period. Confirm the limits match what the client requested. Typos in company names on additional insured endorsements can void the protection entirely. As a result, double-check every line.
What It Will Cost and What to Watch For
The COI document itself is free. Your agent or insurer issues it at no charge. The cost is in the underlying insurance. If you already have a general liability policy, you pay nothing extra for a basic certificate. However, if a client asks for a COI and you need to buy a policy first, expect to pay based on your trade and risk level.
For example, a solo house cleaner may pay around $49 per month. A general contractor with employees may pay $250 to $400 per month for GL alone.
Additional insured endorsements add a small cost. A per-project endorsement runs $20 to $75. A blanket additional insured endorsement covers all clients who require it under one flat fee added to your annual premium. If you regularly work with clients who require COIs, the blanket endorsement typically saves money over time.
Watch for these common traps. First, do not assume your current limits are enough. When a client asks for a COI showing $2 million per occurrence and your policy only provides $1 million, you will need to increase your limits or add an umbrella policy. Second, never alter a COI yourself.
Only a licensed agent, broker, or the insurer can issue or change the document. Altering one is insurance fraud. Third, a COI does not guarantee ongoing coverage. Your policy could cancel the next day. Clients who understand this may require automatic cancellation notices — your agent can set that up.
When to Call Your Agent or an Attorney
For a straightforward request, your agent handles everything. When a client asks for a COI with standard limits and basic certificate holder status, most agents turn it around within a day. However, some situations need closer attention.
Call your agent when the client demands coverage types you do not carry. For example, some clients require professional liability alongside general liability. Others require commercial auto or an umbrella policy. Your agent can quote these quickly. Also call your agent when the client asks for a COI with unusually high limits. Jumping from $1 million to $5 million per occurrence may require an umbrella or excess policy, and your agent can find the best rate.
Call an attorney when the contract includes an indemnification clause that makes you responsible for the client’s own negligence. This is called a “broad form” indemnification, and several states restrict or ban it. In addition, consult an attorney if the client asks for a COI and also demands you waive your right to subrogate — meaning your insurer cannot recover costs from the client if the client caused the loss.

Frequently Asked Questions
How long does it take to get a COI after a client asks for a COI?
If you have an active policy, a basic certificate can be generated instantly through your insurer’s online portal. If your agent needs to add an endorsement — like additional insured status — expect 24 to 48 business hours. In most cases, you can have the document same-day.
Does it cost anything when a client asks for a COI?
The certificate itself is free. You pay nothing to issue it. However, if the client requires you to be named as an additional insured on your policy, the endorsement typically costs $20 to $75. If you need to purchase a new policy to fulfill the request, that cost depends on your trade and coverage needs.
Can I create my own COI when a client asks for a COI?
No. Only a licensed insurance agent, broker, or the insurer can issue a valid COI. Creating or altering one yourself is considered fraud. Use your insurer’s self-service portal or contact your agent directly to get a legitimate ACORD 25 certificate.
What is the difference between certificate holder and additional insured?
A certificate holder receives a copy of the COI and gets notified if the policy cancels. They have no coverage under your policy. An additional insured is actually covered for claims arising from your work. When a client asks for a COI, clarify which status they need — the distinction matters significantly.
What if I do not have insurance yet and a client asks for a COI?
You need to purchase a policy first. Many insurers offer same-day binding for general liability. For example, online insurers like those listed by the SBA’s insurance guide can bind a policy and issue a COI within hours. Confirm with a licensed agent that the policy meets your client’s specific requirements before sending the certificate.
