Which Vendors Need a COI? A Risk‑Based Checklist

Do you need a Certificate of Insurance from every vendor? Not always. Use a risk‑based checklist to decide which relationships truly require a COI.

What is a Certificate of Insurance (COI)?

A COI is a short form that proves a vendor has active commercial insurance. It typically lists the policy type, limits, effective dates, and any special clauses such as additional insured (the party you name on the policy) or waiver of subrogation (prevents the insurer from suing you for a loss they paid).

Why a One‑Size‑Fits‑All Approach Fails

Every vendor presents a different level of risk. A coffee caterer in a small office poses far less exposure than a structural steel contractor on a multi‑million‑dollar project. Requiring COIs from low‑risk vendors creates paperwork overload without improving safety.

Risk‑Based Vendor Checklist

Step 1: Identify the vendor’s role

• Direct contractors who perform work on your premises (builders, electricians, landscapers).
• Suppliers who deliver goods but do not enter the site (paper vendors, office supply firms).
• Service providers with limited physical interaction (IT support, accounting).

Step 2: Assess exposure

• Is the vendor handling heavy equipment, hazardous materials, or large crews?
• Will the vendor’s work cause potential property damage or bodily injury?
• Does the vendor have access to public areas where third‑party claims could arise?

Step 3: Match contract requirements

• Review any written contract or lease for mandated insurance limits.
• Check industry standards – construction often requires $1 million per occurrence / $2 million aggregate.
• Determine if you need the vendor to be listed as an additional insured or to provide a waiver of subrogation.

Typical COI Requirements by Vendor Type

• Construction contractors – Commonly $1 million per occurrence, $2 million aggregate, additional insured, waiver of subrogation.
• Event venues – $1 million general liability, $500 k property damage, and proof of liquor liability if alcohol is served.
• Logistics brokers – $1 million cargo coverage and general liability, often with a certificate naming the shipper as additional insured.
• HOA vendors (landscaping, pool maintenance) – $500 k general liability is typical, plus workers’ comp coverage.
• Small office vendors (catering, cleaning) – $250 k–$500 k general liability may be sufficient, especially if they never enter high‑risk areas.

How to Manage COIs Efficiently

Once you know which vendors need a COI, keep the documents organized and up to date. Set reminders before each policy expires, and follow up directly with the vendor’s insurance agent—no extra account needed for the vendor. Automation reduces missed renewals and protects you from gaps in coverage.

Bottom line

Not every vendor needs a COI, but the ones that could cause significant liability certainly do. Use a risk‑based checklist to focus on high‑exposure relationships, set clear insurance thresholds, and automate the tracking process to stay compliant without the paperwork overload.
