In inventory management, dead stock is the pallet at the back that everyone has stopped mentioning. It sold well once. Then it did not. Every month it stays there, it quietly costs you storage, capital, and the shelf space a faster product could have used. The awkward part is not identifying it. It is deciding what you will accept for it.
Telling dead stock from a slow mover is the first decision, and the two need opposite treatment. This page draws that line, then works down the ladder for clearing whatever is genuinely dead.
What counts as dead stock, and is it the same as obsolete inventory?
Stock moving too slowly to sell through while it is still worth keeping. Obsolete inventory is the harder case: stock that will not sell at any price you would accept. Every product has a point where holding it costs more than writing it off, and for dated goods the selling window decides where that point falls.
The distinction worth drawing early is between slow and dead. A slow mover is still selling. It ties up more cash per unit of sales than a fast one, and if the margin is good it may be entirely worth keeping. Dead stock has stopped moving at a rate that matters. Treating the two the same way gets both wrong: you discount profitable slow lines, and you hold on to genuinely dead ones.
For dated goods the test simplifies: compare days of cover at the current rate against the days of selling window left. Where cover exceeds the window, the surplus is already dead — it just has not expired yet.
What is the markdown ladder?
A pre-agreed sequence of clearing actions in falling order of return: modest discount, bundling with a fast mover, channel shift, deep discount, donation, disposal. Decide the ladder before you need it. That is what stops every markdown becoming a fresh argument.
| Rung | Action | Trigger |
|---|---|---|
| 1 | Modest discount on the main channel | Cover exceeds the window with room to spare |
| 2 | Bundle with a fast mover | Rung 1 did not shift the rate |
| 3 | Channel shift — clearance, wholesale, staff | Under half the window left |
| 4 | Deep discount | Weeks left, still not moving |
| 5 | Donate or dispose | Below the cost of storing and handling it |
The ladder works because it converts a series of uncomfortable one-off decisions into a policy. Without it the pattern is familiar. One small discount, no result, then nothing until the date forces disposal at zero. That is the most expensive path through the same problem.
When does writing it off beat holding it?
When the remaining selling window will not clear the stock at any discount you would accept, or when storage and handling for the rest of that window exceed what the stock could still fetch. At that point the unit is a cost you are choosing to keep paying, not an asset you are waiting to realise.
Two things make this decision harder than it should be. The first is that the loss feels realised at the moment you write it off. It was actually realised months earlier, when the stock was over-bought. The write-off is bookkeeping catching up. The second is space. A slot filled with dead stock is a slot something faster cannot use, and that cost never appears on any report.
Getting to the decision early is worth more than getting it exactly right. A brand that runs the ladder promptly recovers a fraction of cost on most of the stock; a brand that waits recovers nothing on all of it.
What creates dead stock?
Order quantities set by a supplier's minimum rather than by demand, and buffers set generously on slow items. Both decisions are made months before the stock goes quiet, which is why dead stock feels like it appears suddenly. It does not; it was bought.
The generous-buffer version is the one that surprises people, because the advice is standard: hold plenty of cheap, slow items so they need no management attention. That is sound for durable goods. It is actively harmful for dated ones, and it is exactly the correction ABC analysis needs once stock carries a date. The minimum-order version is harder to escape, but the honest response is to price the likely write-off into the run rather than treating the minimum as free. Both are cash decisions with a warehouse attached. That is the shape most problems in a CPG operation take.
What should you do next?
Write the ladder once, then run it on a schedule.
Identify
- Compare days of cover against days of selling window per SKU.
- Separate slow-but-profitable from genuinely dead.
Agree the ladder
- Write the five rungs and their triggers down.
- Name who can authorise each rung without a meeting.
- Start at rung one while rungs still have value.
Stop the source
- Check whether the order quantity came from demand or a minimum.
- Tighten buffers on slow dated items rather than loosening them.
Frequently asked questions
What is dead stock in inventory management?
Stock that is no longer selling fast enough to be worth keeping. Past a certain point it costs you more to keep than to write off. In fashion resale the same word means unworn vintage; in inventory it means the opposite of desirable — units taking up space and cash without moving.
When should you write off dead stock instead of discounting it?
When the next markdown would not clear it inside its remaining selling window, or when the discount needed is below what it costs you to store and handle it. For dated goods the window usually decides before the arithmetic does.
How do you stop dead stock happening again?
Look at what created it. Almost always it is an order quantity set by a supplier minimum rather than by demand, or a buffer set generously on a slow item. Both are decisions made months before the stock went quiet.
