Dead Stock

Dead stock is inventory that hasn't sold within a reasonable timeframe and is unlikely to sell at full price. It ties up capital, takes up warehouse space, and may eventually need to be written off.

Definition

Dead stock is inventory that hasn't sold within a reasonable timeframe and is unlikely to sell at full price. It ties up capital, takes up warehouse space, and may eventually need to be written off.

Understanding Dead Stock

Dead stock is one of the biggest hidden costs in ecommerce. Products become dead stock for many reasons: seasonal items that didn't sell, poor product choices, over-ordering, or market trends shifting. The carrying cost of dead stock includes storage fees, insurance, depreciation, and the opportunity cost of capital tied up in unsold products. Most inventory experts consider stock that hasn't moved in 90-180 days as at risk of becoming dead stock.

Worked Example

Example

You ordered 200 units of a summer dress at £12 each (£2,400 total). By October, you've sold 80 and have 120 remaining. Those 120 units are dead stock, tying up £1,440 in capital. You run a 50% off clearance and sell 60 more, recovering £720. The remaining 60 are donated or written off — a £720 loss.

Why Dead Stock Matters for Ecommerce

Dead stock silently erodes profitability. Money locked in unsold inventory can't be invested in products that actually sell. Storage costs compound over time, and product value depreciates. For seasonal or trend-driven products, delays make the problem worse as the window to sell closes.

Common Mistakes

01

Ordering large quantities to get volume discounts without validating demand first

02

Not monitoring inventory age and velocity to catch slow sellers early

03

Holding onto dead stock hoping it will eventually sell instead of clearing it quickly

Frequently asked questions about Dead Stock

How do I know if I have dead stock?

Look for products with no sales in the last 60-90 days, declining month-over-month sales velocity, or seasonal items past their selling window. Sort your inventory by last-sold date to quickly identify stagnant items.

What should I do with dead stock?

Act quickly: run flash sales or bundle deals, sell on clearance marketplaces, offer them as free gifts with purchase, donate to charity for a tax benefit, or sell in bulk to liquidators. The longer you wait, the less value you recover.

How do I prevent dead stock?

Start with small test orders before committing to large quantities, monitor sell-through rates weekly, use sales data to forecast demand, and set reorder points based on actual velocity rather than gut feeling.
