Inventory – Complete Guide, Metrics & Best Practices
Inventory is more than “goods waiting to be sold” — it is cash in motion, sitting at the intersection of supply, demand, and operational reality. This guide explains what inventory really is, how it links to Operating Working Capital and the Cash Conversion Cycle, and how to manage it with intent.
You’ll learn how to classify inventory by type and purpose, calculate and govern Safety Stock, choose appropriate replenishment methods, and use segmentation to avoid one-size-fits-all policies. We also unpack key metrics (DIO, Turnover, GMROI, fill rate, SLOB), show why transaction-level data is essential, and explore common challenges like bullwhip, planning drift, and SLOB.
The result is a practical playbook for turning inventory from a static capital burden into a strategic capability that supports service, cash flow, and profitable growth.
