How to Reduce Dead Stock: Find It Early and Recover the Cash

5 min read Updated By the Owllys team
The short answer

To reduce dead stock, spot slow movers early — ideally around 60 days before they stall — stop reordering them, and act on what you already hold through transfers, bundles, markdowns or returns to suppliers. Dead stock is inventory that has stopped selling. It ties up cash and space, and every month it sits it costs money to keep.

Key takeaways
  • Dead stock is inventory that has stopped selling but still costs money to hold.
  • Carrying cost is commonly estimated at 20–30% of inventory value a year.
  • The cheapest fix is prevention: stop buying items whose sales are slowing.
  • Act early; the value you can recover falls the longer stock sits unsold.

What is dead stock?

Dead stock is inventory that has not sold for a long period — often six to twelve months, depending on the industry — and is unlikely to sell at full price. Slow-moving stock is the stage before: it still sells, but too slowly to justify how much you hold.

Both cost money every month. Carrying cost — storage, insurance, handling, damage and the cash tied up — is commonly estimated at 20–30% of inventory value a year.

Illustrative example.

Why dead stock builds up

It usually starts with buying decisions. Minimum order quantities push you to buy more than you need. Forecasts lag behind falling demand. A product is replaced, a customer switches supplier or a promotion ends — but reorders continue on autopilot. Items with short shelf lives or fast-changing designs are most at risk.

How to reduce dead stock step by step

Process
  1. 01

    List what is not moving

    Pull every item with no sale in 90 days, with its value and location.

  2. 02

    Find the cause

    Tag each one: over-buying, falling demand, discontinued product, damage or wrong location.

  3. 03

    Stop the inflow

    Block automatic reorders for slow movers until a planner has reviewed them.

  4. 04

    Recover value in order

    Transfer, return to supplier, bundle or mark down — liquidate or scrap only as a last resort.

  5. 05

    Predict the next wave

    Flag items whose sales velocity is falling, around 60 days before they stall.

  6. 06

    Review monthly

    Track dead stock as a share of total inventory value and set a target to reduce it.

How to find dead stock before it happens

Waiting for the year-end report is too late. Instead, track each item’s sales velocity — how fast it sells — against how much you hold. When velocity falls, days of cover climbs. An item covering eight months of sales when it used to cover two is a warning. Prediction models can flag these slow movers around 60 days before they stall, while you can still act.

How to turn dead stock back into cash

Work through the options in order of value recovered. First, move stock to locations where it still sells. Then return it to the supplier if terms allow, bundle it with fast movers or mark it down. Liquidation, donation and scrap come last. Owllys Stocki flags slow movers early, and ReturnNest helps choose the best-value route — restock, refurbish, liquidate or scrap.

FAQ

Questions people ask

How long before stock is considered dead?

There is no single rule. Many businesses treat items with no sales for six to twelve months as dead, while fast-moving or perishable sectors use much shorter windows. Choose a threshold that fits your product life cycle and apply it consistently, so the numbers mean the same thing each month.

Should we write off dead stock or keep trying to sell it?

Compare the realistic recovery value with the cost of keeping it. Unsold stock costs money every month in space, handling and tied-up cash. If a markdown or liquidation recovers more than another year of carrying cost would consume, selling now is usually the better choice.

Can AI predict which items will become dead stock?

Yes, reasonably well. Models compare each item’s sales trend, seasonality, stock level and lead time to flag slow movers weeks before they stall — around 60 days ahead is practical. The value comes from acting on the warning: pausing reorders and moving stock while it can still sell.
