Loss, ageing & obsolescence
Why margin leaks through spoilage, slow movers, and returns — and how to act while stock is still recoverable.
What you'll learn. You will learn to read turnover and ageing signals together, run triage on dead stock, and coordinate seasonal and promo buffers without year-end regret.
Loss shows up long before the write-off
Spoilage, theft, and data drift each need different owners. Seasonal and promo buffers can be rational when you define exit dates and post-mortems. Ageing reports only help when someone has authority to markdown, transfer, or return before the stock is dead on paper.
Turnover and days-on-hand are not vanity metrics — read together with margin and service they show where capital is stuck in the wrong velocity band.
This hub ties together every guide listed below — read in any order, but start from the articles that match your biggest cash or service-level risk this quarter.
