About the workbench
Practical COI preparation without a quote form
COI Workbench helps U.S. contractors and small businesses organize certificate requirements before they contact an insurance agent or submit documents to a client.
Why this site exists
Certificate problems are often discovered at the worst moment: after a contractor wins a job, before a crew can enter a site, or while a vendor account is waiting for approval. The problem is not always a lack of insurance. It may be an entity mismatch, a missing supporting endorsement, an expiration gap, or a vague request that the agent cannot act on efficiently.
Most online resources explain what a COI is. COI Workbench is designed around what a user needs to do next: compare, identify, organize, and ask a better question.
Our operating principles
- Privacy first: core tools run in the browser and avoid requesting policy numbers or document uploads.
- Administrative, not advisory: results identify potential document mismatches and questions to raise; they do not determine coverage.
- Primary sources: regulatory and standards-based sources are preferred over unsupported summaries.
- Visible limitations: every tool explains what it can and cannot establish.
- No fabricated authority: the site does not claim that content has been reviewed by a licensed professional unless that review has actually occurred and is identified.
What we are not
COI Workbench is not an insurance company, agency, broker, law firm, compliance platform, certificate issuer, or coverage verification service. It does not bind insurance, alter policy language, communicate with an insurer on a user’s behalf, or guarantee that a client will accept a submission.

Publishing responsibility
Who is behind the content
“COI Workbench Editorial Desk” is the site’s publishing identity. It distinguishes the public work from an administrator login name; it is not the name of a licensed reviewer, insurer, broker, law firm, or certification body. When a qualified professional reviews a page and authorizes public attribution, that person’s name, credential, scope of review, and review date will be shown on the relevant page. Until then, the site describes its work accurately as source-led educational publishing and software quality assurance.
How a guide earns a place on the site
A specific problem
Each guide starts with a recognizable contractor action, such as responding to a rejection, comparing dates, identifying the right entity, or documenting a portal receipt.
The right authority
Client requirements, policy-backed evidence, project facts, delivery records, and reviewer decisions remain separate so the site does not manufacture a conclusion.
A next step
The page should leave the reader with a checklist, comparison, question route, example, or related browser tool—not merely a definition rewritten for search.
How the tools are checked
Tool interfaces are reviewed for keyboard access, readable contrast, responsive layout, required-field behavior, conservative result labels, and clear limitations. Calculations and classifications are tested with ordinary, missing, conflicting, and boundary inputs. The tools intentionally avoid document uploads, policy numbers, account creation, and remote processing of user entries. Exports are generated in the browser when the user requests them. A tool can organize user-entered facts; it cannot authenticate the source material or determine whether insurance applies.
Funding and independence
The site may be supported by clearly identified advertising. Advertising does not change a tool result, decide which insurer or broker is recommended, or purchase a favorable editorial conclusion. COI Workbench does not sell insurance and does not require a quote request to use its core tools. If an affiliate, sponsorship, or other commercial relationship is introduced, it will be disclosed where a reader encounters the relevant recommendation or link.
How readers can hold the site accountable
Every material guide links to sources and the site-wide methodology. Readers can use the Contact page to identify a factual, technical, privacy, or accessibility problem without sending insurance documents or confidential project data. Confirmed material errors follow the Corrections Policy. The Sources and Methodology page records the current tool boundaries and update process.
