A certificate of insurance (COI) is a one-page summary document proving that an insurance policy exists. It shows the named insured, the carrier, the coverage types, the limits, and the policy dates. It is evidence of coverage — it is not the policy, and it does not itself grant coverage.
Why agencies issue so many of them
In commercial lines, a COI is a precondition for doing business. A general contractor will not let a subcontractor on site without one. A landlord requires one before a tenant takes possession. A client's procurement department requires one before releasing a purchase order — often with specific limit requirements and additional insured language.
The result is volume: a mid-size commercial agency can issue hundreds of certificates a month, most of them near-identical, many of them urgent.
The additional insured wrinkle
Requests frequently ask for a third party to be named as additional insured or for a waiver of subrogation. These are not certificate edits — they are policy endorsements that must actually exist on the policy. Issuing a certificate that represents coverage the policy does not provide is a genuine E&O exposure, which is why certificate work cannot be blindly automated.
What can and cannot be automated
Safely automatable: intake and classification of the request, checking the requested language against endorsements already on file, generating the document, and delivering it.
Not automatable: deciding to grant coverage terms the policy does not contain. The correct design routes those requests to a human with the mismatch already flagged — which is both faster than manual review and safer than an unsupervised bot.
