Vendor certificates of insurance (COI)

ACORD 25 certificates checked against your requirements

Limits, policy dates, additional insured and certificate holder for every vendor.

The problem

Vendors send COIs with expired policies or limits below the contract.
The additional insured box is empty or the certificate holder is wrong.
Renewals tracked in spreadsheets.

With Constaia

Policy dates checked against the job date; limits extracted as numbers for your own rules.
require_fields for additional insured and the coverages you need.
Webhooks and metadata to update the vendor record automatically.
