What Is Inventory?
Inventory is the stock your business owns and hasn't sold yet, valued at what it cost you — the foundation every stock-related decision in your business is built on.
Direct answer
Inventory is the stock your business owns and hasn't sold yet, valued at what it cost you. "Stock" and "inventory" are generally used interchangeably by shop owners — there's no meaningful difference in everyday use, though "inventory" is the more formal accounting term for the same thing.
Basic stock valuation
A shop has 150 padlocks left on the shelf, each costing ₵80.
| Quantity | 150 |
| Cost per unit | ₵80 |
| Stock Value | ₵12,000 |
Why accurate stock records matter
Your stock value feeds directly into Cost of Goods Sold, which feeds into Gross Profit and eventually Net Profit. If your recorded stock doesn't match what's actually on the shelf, every number built on top of it is wrong in the same direction — not just your inventory count, but your entire profit picture.
How this connects to real problems
Once inventory is tracked accurately, three separate questions become answerable: whether stock is disappearing somewhere it shouldn't (Stock Loss), whether stock is present but not selling (Dead Stock), and how fast stock overall is moving through the business (Stock Turnover). If your records themselves are unreliable, none of those three questions can be answered honestly — that's what the stock accuracy diagnostic is for.
