Inventory is money sitting on a shelf

How stock accumulates without a decision

Very few businesses decide to hold excess inventory. It arrives through a series of individually reasonable choices. A supplier offers a better price on a larger quantity. A sales manager wants availability so an order is never lost. A production run is extended because the setup is already done. An item is ordered because it was ordered last year.

Each decision makes sense in isolation. Together they can absorb a substantial share of the working capital of the business, and because stock appears as an asset on the balance sheet, the accumulation attracts little attention until cash becomes tight.

Look at ageing, not the total

The total inventory value tells you very little. The distribution tells you almost everything. Split stock by how long it has been held: under ninety days, ninety to one hundred eighty, one hundred eighty to three hundred sixty five, and beyond a year.

In many businesses, a surprising portion sits in the last two buckets. That stock is not an asset in any practical sense. It is cash that has been converted into an object nobody currently wants, and it will usually be sold eventually at a discount that erases the margin it was bought for.

Do the same analysis by item rather than category. Categories average out the problem. Item level detail identifies it.

Availability and excess are not the same argument

The strongest internal defence of high stock is service level. Losing a sale because the item was unavailable is a visible failure. Holding the item for eleven months is an invisible one, and invisible costs lose arguments.

The way through is to separate the two. Identify the items that genuinely drive service, usually a modest proportion of the range, and protect their availability properly with sensible reorder points. For the long tail, accept longer lead times, order against demand and stop carrying stock on the assumption that someone might ask.

A simple illustrative calculation helps the conversation. If holding an extra month of stock costs the business the finance cost, the storage, the handling and the eventual markdown risk, the discount offered for the bulk purchase often turns out to be a poor trade.

Purchasing discipline is where it is fixed

Inventory problems are solved upstream. That means a purchase plan tied to actual demand rather than habit, approval limits that are respected, and a review of any order that exceeds a defined cover period.

It also means someone owning the number. Where inventory belongs to everyone, it belongs to nobody. A monthly review of ageing, slow movers and cover days, attended by purchasing, sales and finance together, surfaces disagreements that email never will.

Clearing existing excess requires a decision about loss recognition. Many businesses hold dead stock for years to avoid writing it down, which is an expensive way to protect a number in a report. The cash released, and the space, is usually worth more than the accounting comfort.

A closing thought

Treat the warehouse as a bank account with goods in it. Every item on the shelf represents money the business has already committed. Once management starts reviewing it that way, purchasing behaviour changes quickly.
