A five-minute tour of Binder.

This walks you through a real book of vendors — a property manager in Charlotte with eighteen of them, eight not clear to work. Open each screen and see for yourself. It takes about five minutes and you do not need to talk to anyone.

A certificate of insurance confers no rights. It says so in its own header: issued as a matter of information only, and does not amend, extend or alter the coverage afforded by the policies. The endorsement is what protects you — and it is the one thing an expiry-date column cannot see.

One shared demo account. Nothing you do here affects anything real — the data resets every night.

  1. Start with who cannot work today

    The overview answers one question: which vendors are covered right now, and which are not.

    Look at: 56% compliant, and 8 of 18 vendors not clear to work — two of them have never sent a certificate at all. Then look further down at the renewals table: the address it gives you is the broker's, not the vendor's. The agency is who issues the certificate, and chasing them directly is the difference between three days and three weeks. Open the overview →

  2. Open the vendor whose certificate looks fine

    Go to Vendors and open Keystone Roofing LLC. The certificate is on file, the general liability runs to next February, and everything looks in order. It has three blocking defects.

    Look at: the two panes — the certificate as submitted on the left, the verdict against your contract on the right.
    • Products / completed operations aggregate is $1,000,000 against a required $2,000,000. The general aggregate is fine. This is a different limit on the same policy, and it is the one that answers for work already finished.
    • Additional insured — completed operations is not evidenced. The tick in the certificate's box is the broker's summary. The engine asks for the CG 20 37 endorsement itself.
    • The auto policy has lapsed — while the general liability on the same certificate is still in force. "Is it expired" has no single answer; it has one answer per policy.

  3. Read the letter it writes

    Same page, then Deficiency letter. This is what goes to the agency.

    Look at: the three findings in language an agency can act on in one pass, your holder wording spelled out in full, and the closing line that asks for the endorsement itself, not another certificate — quoting the certificate's own disclaimer back at it.

  4. Then the screen that does the actual work

    Still on the vendor page, find Upload link and click Open it. This is what the vendor's insurance broker sees.

    Look at: no account, no password — and every required limit and endorsement form number shown before they submit anything. Most back and forth with an agency exists because nobody told them the numbers up front. Submit a corrected certificate here and the vendor turns compliant, the open request closes itself, and the old certificate is kept as superseded rather than overwritten.

  5. Check what everyone is being measured against

    Open Requirements. A landscaper and a roofer should not be held to the same list.

    Look at: three sets — trade contractor, grounds & janitorial, professional services — each with its own coverage lines, its own required endorsements by form number, and its own minimum A.M. Best rating and financial size for the carrier standing behind it. Ratings are compared in rank order, so a set asking for A− accepts A++, A+, A and A−. Open requirements →

What it does not do

It does not read certificate PDFs — someone enters the figures, either your reviewer or, better, the broker through the portal. It does not send scheduled reminder emails; it shows you what is expiring and who to chase, and you send from your own mailbox. There is no CSV export, no A.M. Best data feed, and requirement sets are per vendor rather than per project. It also does not stack an umbrella over a shortfall in the underlying policy — the finding text says so where it applies. And no certificate tracker, including this one, can tell you a policy is genuinely in force: a certificate is evidence, not verification. All of that is fixable or scopeable, and I would rather you read it here than find it later.

If you want it on your own domain

$4,800 one time. No subscription. First working version in five working days.

For comparison: myCOI requires a minimum of 200 incoming certificates and starts above $500 a month on a custom contract after a mandatory demo. Below that line the market is a spreadsheet with a colour-coded expiry column. This is paid once and runs on your own instance.

You get a perpetual licence to use and modify your instance, and a dedicated one — your data is never pooled with another customer's. Hosting and nightly backups are included for the first 30 days; after that either I keep it running for $99 a month, or I hand you the database, the source and the setup notes to run it anywhere. No lock-in either way. Reply with one question about your own vendors and you will get a straight answer the same day, including if this is not the right fit for you.
