The Silent Margin Killer: What Dead Stock Really Costs
By Allan C. Haynes FCCA FCA CTP
Last week we chased down the cash trapped in receivables. This week we open the other big store of hidden working capital: inventory. For any business that holds stock, the shelves are the quietest place your cash goes to sleep—and the balance sheet flatters it, because inventory is recorded as an asset. A great deal of it is nothing of the sort. It is cash you have already spent, sitting in a box, paying rent.
Inventory is not an asset until it sells
An accountant will tell you stock is a current asset, and technically it is. But cash you cannot spend is not working for you, and stock that will not sell for months—or ever—is a liability wearing an asset's clothing. The relevant question for an owner is never "what is my stock worth?" It is "how quickly does my stock turn back into cash, and what is the slow-moving portion costing me to hold?"
Measure the turn
Your Days Inventory Outstanding—the DIO from the Week 4 cycle—tells you, on average, how many days stock sits before it sells. But the average hides the real story, and the real story is almost always the same: a small share of your lines drives most of your sales, and a long tail of slow movers drags the whole cycle out. Rank every product by how fast it sells and how much cash it ties up. The picture is usually stark, and usually actionable within a week.
The true carrying cost
Holding stock costs far more than its purchase price. Add the storage and the space; the insurance and handling; the obsolescence and spoilage; the shrinkage; and—the one owners routinely ignore—the opportunity cost of the cash itself, which could be paying down a facility or funding a fast-moving line instead. As a rule of thumb, holding inventory for a year costs a fifth to a quarter of its value on top of the value. Dead stock is not sitting still. It is quietly billing you.
Freeing the cash
- Cut the tail decisively. Discount slow movers while they still have value rather than writing them off later at zero. A line sold at cost releases cash and space; the same line written off next year does neither. Sentiment is expensive here.
- Order to demand, not to comfort. Smaller, more frequent orders on fast lines beat large "safe" buys that park cash for months. Overbuying to feel secure is one of the most common ways good businesses starve themselves of cash.
- Use supplier terms as a buffer. Align what you owe suppliers with how fast the stock sells (the payables lever from Week 5). Stock that sells in three weeks but is paid for in eight is funding itself.
- Watch the trend, not just the count. A line whose sales are slowing is tomorrow's dead stock. Catch it while a modest discount still clears it.
A word on seasonality
For many Caribbean businesses, stock is deeply seasonal—tourism peaks, Crop Over, Christmas. Seasonal buying is legitimate, but it must be planned against the 13-week forecast from Week 9, not bought on hope. The discipline is to know precisely when the season's stock must convert to cash, and to have a clear plan for whatever does not.
Your one action this week: identify the five slowest-moving items tying up the most cash, and decide a clear-out price for each today. Turning even part of that shelf back into cash is a loan you give yourself, interest-free.
