What is inventory management?
Knowing what you hold, what it cost, and what to do before it runs out or goes stale.
Last checked 20 September 2026
Inventory management is knowing what stock you hold, what it cost, how fast it moves and when to buy more. For a distributor it is the largest single use of working capital in the business, which is why the difference between doing it well and doing it roughly shows up directly in profit.
The four questions it has to answer
| Question | What answers it |
|---|---|
| What do I have right now? | An accurate count, per item, per batch |
| What did it cost me? | A valuation method applied consistently |
| When do I buy more? | A reorder point per item |
| What is not moving? | Turnover and ageing |
Most businesses answer the first one approximately and the other three not at all. That is where the money goes.
Stock is money in a different shape
A distributor holding ₹40 lakh of stock has ₹40 lakh not in the bank. It costs in four ways at once:
- Capital tied up — money that could have paid a supplier early for a discount, or not been borrowed at all.
- Space and handling — warehouse, shelving, people moving it about.
- Obsolescence — goods that quietly stop selling.
- Expiry — for dated goods, a hard deadline. Stock that expires is not a slow seller, it is a write-off.
Against which sits the cost of not holding enough: lost sales, and a customer who finds out their second-choice supplier is fine.
Track it at batch level, not item level
"200 units of product X" is not enough for anyone dealing in dated or traceable goods. Two deliveries of the same product bought three months apart have different costs and different expiry dates. Collapse them into one number and you lose the ability to price correctly, to recall accurately, and to clear the oldest first.

The numbers worth watching
| Number | Tells you |
|---|---|
| Stock value | How much capital is sitting on the shelf |
| Days of cover, per item | How long the current stock lasts at recent sales |
| Inventory turnover | How many times a year your stock money goes round |
| Items below reorder point | What to order today |
| Value expiring within 90 days | What to push, discount or return — while you still can |
| Items with no sales in 6 months | Dead stock, pretending to be inventory |
When a spreadsheet stops coping
Roughly at the point where any of these becomes true:
- More than one person updates stock.
- The same product exists in several batches with different costs or expiry dates.
- Somebody has to add up a column to answer "how much of this do we have".
- The sheet and the shelf disagree often enough that people check the shelf anyway.
The tell is the last one. Once staff stop trusting the number, the sheet has become data entry with no benefit attached.
The habit that fixes most of it
Make stock move as a consequence of paperwork, not as a separate task. Goods in when the purchase bill is entered; goods out when the invoice is raised. Nobody updates stock as a chore, so nobody forgets.
How often should we do a physical count?
A full count at least annually, and cycle counts — a few items every week — in between. Cycle counting finds problems while they are small and does not require shutting the warehouse.
Our system and our count never match exactly. Is that normal?
Small differences are normal. A pattern is not. If the same items are always short, that is shrinkage, mis-picking or a unit-of-measure problem, and it is worth finding.
What is a good stock level?
There is no single answer. It is set per item, from how fast it sells and how long your supplier takes. See reorder point and safety stock.
