Stock age counts days from purchase to sale. By default, slow-moving starts at 30 days and dead stock at 60 days.
Stock age is the number of days a device has been with the shop, counted from the day it was received until it sells, or until today if it hasn't. The longer it stays, the more capital is tied up, the more the market price falls and the higher the holding cost.
Where you see stock age
-
The Stock age column on Inventory, oldest first when sorted by Oldest in stock
-
The stock age label on the item page, which turns amber and then red as the device waits
-
The stock age card on the Overview, in age bands, with the capital in each band if you can see costs
-
The inventory aging and dead stock reports. See Stock age and aged stock reports.
How slow-moving and dead stock are counted
The shop sets two thresholds (defaults shown):
| Group | Condition |
|---|---|
| Slow-moving | Age of 30 days or more, but below the dead-stock threshold |
| Dead stock | Age of 60 days or more |
Only devices the shop still holds are counted, such as received, awaiting repair, ready to sell, listed, reserved and in a branch transfer. Sold, written-off and voided devices don't count. A device in repair keeps ageing.
The owner or an admin can change the thresholds in Store settings. See Set the slow-moving and dead-stock thresholds.
Where the thresholds are used
-
Store Intelligence flags slow-moving and dead stock, with the capital tied up. See Dead and slow stock alerts: what to do.
-
The dead stock and inventory aging reports use the same thresholds.
-
The stock age card on the overview uses the shop's dead-stock threshold.
How stock age differs from Days-to-Sell
Stock age starts on the day of purchase. Days-to-Sell starts when the device is first ready to sell and ends when it sells. A device that spent a long time in repair therefore has a higher stock age than Days-to-Sell. The system uses Days-to-Sell to estimate how quickly a model sells and to work out the holding cost in Safe Buy.
