The audit premium

Every missing COI could cost you thousands.

When your insurance company audits you, they add up what you paid your subcontractors. For anyone without a certificate on file, that money gets rolled into your premium — as if they weren't insured at all. Miss a few, and it adds up fast.

The fix is simple: a certificate on file for every sub. That's what CertRanger is here for.

At audit · example
Paid to subcontractors $420,000
Subs with no COI on file 3
Added to your premium + $18,400
A charge you should never have to pay.
The chase

The hard part is getting them to send it.

You send the request. Then you wait. Then you send it again. And it's not just on you — a sub can't issue their own certificate, so they're chasing their insurance agent while you're chasing them. It's a hassle for everyone. CertRanger does the chasing for everyone: it asks, follows up, and keeps nudging until the certificate comes in.

And if it still doesn't show up, we'll let you know when it's worth reaching out to the sub yourself.

How it works

Add your subs. We take it from there.

No more playing tag with your subs. We even make it easy for them and their insurance agent.

1 you
You set it up.

Tell us the coverages and limits you require, and how you should be named as additional insured. Add your subs — or upload certificates you already have.

2 your sub
Your sub taps a link.

We send your sub an emailed link. They can upload the COI if they have it, or give us their agent's info so we can contact the agent for them. Your sub doesn't have to play middleman.

3 their agent
Their agent issues it.

The agent gets the exact spec — who to name, the wording, the limits, the dates — and uploads the certificate. We read it, check it against what you asked for, and let everyone know.

4 you
You're audit-ready.

Your dashboard shows every sub at a glance — good to go, waiting, or needs a fix. At audit time, it's easy to export every certificate plus a coverage summary in one click.

What makes it different

We actually read the certificate.

A certificate can look perfectly fine and still be wrong — the wrong company listed, dates that don't cover your policy period, coverage amounts that fall short. A spreadsheet or a folder full of PDFs will never catch that. CertRanger reads every one and checks it against what you asked for, across every kind of coverage you require. If something doesn't line up, we'll let you and your sub know.

CertRanger reads what each certificate states and checks it against your requirements. It catches honest mistakes — not fraud.

Checked on every certificate
The right company listed as additional insured — not just certificate holder
Dates that cover your whole policy period, including mid-year renewals
Limits that meet the minimums you set
Every coverage you require — General Liability, Auto, Umbrella/Excess, Workers' Comp, and more
The fine print — waiver of subrogation, primary & non-contributory, umbrella stacking
Audit-ready

When audit time comes, it's all right here.

Every certificate on file, plus a month-by-month coverage chart for the year, in one place. Print it, save it as a PDF, hand it to your agent. A frustrating annual chore is now just a few clicks.

Subs & agents

Why subs and agents love it

It turns out the fastest way to get a COI is to make it painless for the person sending it. So we did.

It all means the right COI shows up — and you didn't have to hound anyone to get it.

Collect. Review. Ready. So audit day is a non-event.
