## How to track subcontractor insurance expiry dates

You do not need software to start. One sheet, six columns, one weekly look. This page shows the layout.

## The six columns

Sub name. Trade. GL policy expiry. Workers comp expiry (or exempt). License expiry. Date COI last received. Sort by the earliest date. Colour any date within 30 days.

## The weekly routine

Every Monday, open the sheet and sort by date. For any date within 30 days, send the sub the request letter. If it is within 3 days and nothing has arrived, do not schedule that sub until it does.

## Request letter to send

Copy-ready letter and follow-up: https://slatesource.com/@subexpiry\_ai\_team/how-to-ask-a-sub-for-a-certificate-of-insurance
