COI Tracking Software vs. Spreadsheets: When to Switch
The CertifiKit team
Certificate-of-insurance desk
A spreadsheet is the right tool for tracking a handful of certificates of insurance. Dedicated software earns its place once the manual work of chasing, reading, and verifying COIs costs more time than the software does. For most small operations that crossover happens somewhere around 30 active vendors — but the real trigger is the kind of work, not just the count.
What a spreadsheet does well
Don't switch before you need to. A well-built COI tracking spreadsheet is free, familiar, and perfectly adequate when you have a short, stable vendor list. It can hold each vendor's expiry date, store limits, and even fire a conditional-format warning when a certificate is about to lapse.
For ten vendors who renew once a year, that's genuinely all you need.
Where the spreadsheet quietly breaks
The spreadsheet tracks that a certificate exists. It can't tell you whether the certificate is actually correct. That gap is where the manual hours pile up:
| Task | Spreadsheet | Dedicated tooling |
|---|---|---|
| Store expiry dates | Yes | Yes |
| Warn before expiry | With a formula | Automatic |
| Read limits off the PDF | You, by hand | Automated |
| Confirm additional insured / endorsements | You, by hand | Automated |
| Chase missing or wrong COIs | You, by email | Automated reminders |
| Survive staff turnover | Lives in one head | Shared system of record |
Every "you, by hand" row is a place where, at volume, something gets skipped — and the thing that gets skipped is usually reading the ACORD 25 closely enough to catch a missing endorsement.
The signs you've outgrown the spreadsheet
- You're spending real time each week opening PDFs and squinting at limits and endorsement checkboxes.
- Renewals are slipping through because the reminder formula only helps if someone's looking at the sheet.
- More than one person needs the current status, and the file keeps getting out of sync.
- A vendor's coverage lapsed and nobody noticed until it mattered.
If two or more of those are true, the spreadsheet is now costing you more than it saves.
You don't have to commit to find out
The switch doesn't have to be all-or-nothing. Keep your spreadsheet for tracking dates, and use the free CertifiKit checker for the part the spreadsheet can't do: upload any certificate and it reads the limits, dates, and endorsements, checks them against your requirements, and tells you in plain English whether the COI is actually compliant. No account, no sales call — a way to feel the difference before you change anything.
