COI compliance for property managers
An expired certificate of insurance is a lawsuit waiting to happen.
COIStack tracks every vendor and tenant's insurance and emails you before it expires. No more digging through a spreadsheet to find out who's actually covered, and no more finding out too late.
Free during beta. No credit card.

A 30-second look at tracking every vendor and tenant COI.
Why it matters
One lapsed policy is all it takes.
Insurance certificates expire on their own schedule, and nobody sends you a reminder. Until something goes wrong.
The uninsured vendor on site
Almost let one on site last week? A lapsed policy plus one accident, and the claim lands on the property owner, not the vendor.
600 hours in a spreadsheet
One property manager counted over 600 hours a year updating COI spreadsheets. It still never warned them a policy was about to lapse.
Slipping through the cracks
COIs and renewals slip the minute you get busy. There's no alarm on a row in Excel, so you find out the hard way.

Built for the person who's actually on site.
If you hire vendors and you're the one holding the liability, this is for you.
The real problem
Property managers keep saying the same thing.
“Almost had an uninsured vendor on site last week. How are you all managing your COIs?”
“How do you keep COIs and lease renewals from slipping through the cracks?”
“Is a tool that requests COIs and does the follow-ups actually worth it? For us, yes.”
How it works
Set it up once. Stop worrying about it.
Three steps, about ten minutes, and every certificate is on the clock.
STEP 01
Add vendors and tenants
Enter them one by one, or bulk import your whole list from a CSV.
STEP 02
Upload each COI
Drop in the PDF and the expiry date. Edit or delete anything later in seconds.
STEP 03
Stay ahead of expiry
Reminders arrive on the days you choose, 30 and 7 out by default, and one click requests an updated COI.

Everything you need, nothing you don't.
Vendors and tenants together

Questions
Good to know.
Do I need to install anything?
No. COIStack runs in your browser on any device. You can also install it as an app if you prefer.
Can I track tenants too, or just vendors?
Both. Vendors and tenants live side by side in one place.
What certificates can I track?
Any COI: general liability, workers comp, auto, umbrella, and more. Upload, edit, or delete each one as things change.
How do I chase an expiring certificate?
Click Request updated COI and we email the vendor or tenant for you. Their reply comes straight to your inbox.
Can I change when reminders are sent?
Yes. Pick your own first and second reminder days in Settings, and see a history of what was sent. New accounts start at 30 and 7 days before expiry.
Can I import and export my list?
Yes. Bulk import your vendors from a CSV, and export a one-click compliance report as CSV for owner updates.
Is my data private?
Yes. Your vendors, tenants, and documents are visible only to your own account.
What does beta cost?
Nothing. It's free during our public beta. After that, there's a free plan for up to 25 vendors and a Pro plan at $27 a month for unlimited vendors and tenants. One flat price, never per vendor. Cancel anytime.
