Ask anyone who’s spent a few years in supply chain or finance to share an “inventory horror story” and you’ll see the same reaction: a tiny smile, a long sigh, and a number they still remember way too clearly.
Not because something exploded in the warehouse.
Because money quietly disappeared in slow motion, in boxes, on racks, under a layer of dust.
Here are three stories that repeat across industries, plus what could have changed the ending.
1. The Engineering Change That Never Left the Spreadsheet
On paper, it was a success: engineering released a new revision of a key assembly, solved a quality issue, everyone was happy.
The problem?
The old revision stayed alive in the real world.
Three plants still had stock. A contract manufacturer had months of material in their cage. The ERP showed on hand, but nobody connected it to the change. Production moved on. The parts became “don’t use” overnight.
Eighteen months later, finance asked for an E&O review. Someone pulled the report.
There it was: a six-figure block of inventory that was technically perfect – and completely unusable.
How this could have been avoided:
Any engineering change that touches a part number must automatically trigger one question: What happens to what we already bought?
Before the ECO is “closed”, someone owns checking on-hand and on-order and deciding… use-up, rework, alternate application, or controlled write-off.
Previous revisions show up on a simple “watch list” until they’re gone.
The horror isn’t the change. It’s pretending the old stock will somehow magically disappear.
2. The “Minimum Order Quantity” deal that looked great… until it didn’t
A supplier offers attractive pricing – as long as you commit to a chunky minimum order. Procurement does the math, unit cost drops, and the deal looks smart.
The first year, demand supports it. The second year, it’s “okay”.
By the third year, the market has shifted. The product mix changes, a big customer switches platforms, demand slides.
The MOQ, however, doesn’t care.
You keep buying more than you need to “protect price”. Pallets pile up: components you might use “someday”, but that day never quite arrives. When finance finally forces a cleanup, you discover how expensive that “discount” really was.
How this could have been avoided:
Someone regularly compares MOQ to real consumption and flags gaps.
When the numbers drift, you renegotiate – pooled buys, flexible blankets, different price breaks – instead of pretending demand will come back to match an old deal.
The impact of MOQs on E&O is visible in sourcing reviews, not buried in a year-end adjustment.
Cheap per unit is not cheap if it ends its life in the write-off column.
3. The Year-End Surprise
All year long, teams are busy with the urgent stuff: shortages, expedites, launches, escalations.
E&O is “on the list”, but never at the top.
Then December arrives. Finance asks for the latest excess and obsolete position. Operations pulls a full report for the first time in months. Suddenly everyone is discovering slow movers, dead items, and “temporary” buys that never moved.
At that point, the options are ugly: either a big write-off that hurts the P&L, or a fire sale that recovers a tiny fraction of the original value.
Everyone leaves the meeting saying, “Next year we’ll get ahead of this.”
Next year looks suspiciously similar.
How this could have been avoided: E&O is reviewed monthly, not once at year-end.
There’s a simple, shared view of at-risk items that both supply chain and finance look at.
Once an item is clearly not coming back into the plan, the question is how to exit, not whether it might magically turn.
The horror isn’t the report. It’s realizing you could have acted six months earlier.
You can’t get to zero. But you can choose the ending.
No real business runs with zero excess and obsolete inventory. Demand shifts, designs change, MOQs exist, acquisitions happen. A certain level of E&O is the cost of playing the game.
The difference is whether E&O shows up as:
- a controlled by-product you manage early, with clear owners and decisions, or
- a recurring horror story you only face when the auditor or the CFO forces the conversation.
Good habits upstream – solid change control, honest demand reviews, regular slow-mover visibility, smarter MOQ discussions – won’t make the problem disappear. But they drastically shrink the surprise and the damage.
And for the portion you still can’t avoid, you don’t have to accept “write it off and move on” as the only plot twist. Structured ways to turn idle stock back into cash, with clear governance and the right incentives, change the ending completely.
Because at the end of the day, inventory horror stories aren’t really about boxes.
They’re about cash, trust, and how long a problem sits in the dark before someone decides to do something about it.
