HVAC contractors often lose time because vendor paperwork is scattered across emails, expired documents, old PDFs, and last-minute client requests.

Suggested folder structure
| Folder | What goes inside |
|---|---|
| 01 W-9 | Current signed W-9 |
| 02 Insurance | COIs and policy notes |
| 03 Licenses | License copies and renewal notes |
| 04 Client Forms | Property manager or client-specific packets |
| 05 Expiration Tracker | Spreadsheet or calendar reminders |
| 06 Submitted Packets | Copies of what was sent and when |
Why this matters
When a property manager asks for paperwork, a clean packet makes you look organized and easier to approve. Messy paperwork can delay onboarding even when your work is good.
