Dead stock
Dead stock is inventory that has not sold or been used within its expected cycle — typically 6 to 12 months — and is unlikely to move without a markdown, repurposing, or disposal. It ties up cash and storage space while contributing nothing to revenue, and it drags down inventory turnover even when total inventory value still looks healthy on paper.
What causes dead stock
Dead stock is inventory that has gone roughly 6 to 12 months — sometimes longer, depending on the category — without a sale, use, or transfer. Fashion and perishables cross that line in weeks; industrial parts can sit far longer before they count as dead.
It usually comes from over-ordering against a forecast that did not hold up, a discontinued product no one flagged, bad location data that hides stock from staff, or simply buying more before checking what was already on the shelf. The common thread is a decision made without a current view of what is actually on hand.
Why dead stock is expensive
Every dollar sitting in dead stock is a dollar that cannot buy inventory that actually sells, which is why dead stock drags down inventory turnover even when total inventory value looks fine on paper. Beyond the tied-up cash, it keeps taking up shelf or warehouse space, adds line items to every physical count, and can quietly mask real inventory problems behind an inflated total.
Worked example: the cost of letting it sit
A gift shop bought 200 units of a seasonal ceramic ornament at $8 each — $1,600 in cost. Fourteen months later, 60 units are still on the shelf, and none of them has sold or moved in the last 9 months. Those 60 units are $480 of dead stock.
At a conservative 2% of cost per month in carrying costs (storage, insurance, opportunity cost), that $480 quietly costs the shop about $9.60 a month just to keep sitting there. Left unaddressed for another year, the same $480 of dead stock would cost roughly $115 in carrying costs alone — nearly a quarter of what the ornaments were worth to begin with.
How to identify and clear dead stock
A monthly "no movement" review catches dead stock while it still has resale value, instead of waiting for an annual count when a year of carrying cost has already been paid. Sort the catalogue by last activity and look for items that have not sold, been checked out, or been adjusted in months.
From there the usual playbook is to discount aggressively, bundle a slow mover with a fast one, return it to the supplier if the terms allow, or write it off outright so it stops distorting the picture of what your inventory is actually worth. Be careful not to treat every slow mover as dead: a seasonal item that reliably sells every December is dormant, not dead, and discounting it away is a mistake.
How StockZip helps with dead stock
StockZip logs a timestamped movement history for every item, which is the raw signal dead-stock detection depends on. You can sort or review the inventory list by last activity to see which items have not moved in months — and use folders, tags, and low-stock alerts to keep active stock organised and reordered so dead stock is less likely to pile up in the first place.
A dedicated aged-stock report that surfaces "no movement in 90 days" automatically is part of StockZip's paid reporting, not the free tier — but the underlying movement history that makes the review possible is recorded on every plan.
