Vendor files can look fine until something urgent happens. Then everyone realizes the COI is expired, the W-9 is missing, the contact is outdated, or nobody knows which vendor is approved.
Quick answer
A vendor audit should check every active vendor for current insurance, W-9, license status if needed, contact information, service type, and approval notes.

Vendor audit checklist
| Item | Check |
|---|---|
| Vendor name | Is the legal name clear and consistent? |
| Service type | Do you know what work the vendor performs? |
| Main contact | Is the phone and email current? |
| W-9 | Is it saved and easy to find? |
| COI | Is the certificate current? |
| License | Is a license required for this work? |
| Expiration date | Is it tracked in a spreadsheet or reminder system? |
| Approval status | Is the vendor approved, pending, expired, or archived? |
Simple audit workflow
- Export or list every active vendor.
- Create one row per vendor in a tracker.
- Open each folder and mark missing documents.
- Sort by COI expiration date.
- Email vendors missing paperwork.
- Move inactive vendors to archive.
Red flags
- COI expired more than 30 days ago
- vendor folder has no W-9
- no clear point of contact
- duplicate vendor records
- documents saved only in email
- no approval status
Final thought
A vendor audit is not about making paperwork pretty. It is about reducing panic when maintenance, billing, or risk questions show up.
