Every retailer has a few products that just won’t sell. They sit on the shelf, take up space, and quietly tie up cash that could be working somewhere else. That’s dead stock — and if you’ve ever done a physical inventory count and thought, “wait, we still have all of this?”, you’ve run into it firsthand.
The good news is that dead stock is fixable. The first step is simply knowing it’s there.
What Counts as Dead Stock?
Dead stock is inventory that hasn’t sold within a defined period — commonly 60, 90, or 120 days — and is unlikely to sell without some kind of intervention, like a markdown, a bundle, or a return to the vendor.
It’s different from a slow mover, which is still selling, just not quickly. Dead stock has effectively stopped moving.
Quick answer: To identify dead stock in Lightspeed Retail, run an inventory report filtered by last-sold date, then sort by dollar value to see which unsold items are tying up the most cash. A 90-day window is a good starting point for most retailers.
Why Dead Stock Happens
Dead stock rarely comes from one bad decision. It usually builds up from a few common causes:
- Overbuying for a season. Ordering based on hope rather than last year’s actual sell-through.
- Reordering out of habit. A product that used to sell well keeps getting reordered even after demand has dropped.
- No clear reorder point. Without a system flagging slow sellers, they’re easy to miss until a physical count.
- Multi-location blind spots. A product might be dead at one store and fine at another, but a combined report can hide that difference.
- Trend or seasonal misses. A color, size, or style falls out of favor faster than expected.
None of these are signs of poor management — they’re just the natural result of running a business with limited time to dig through every report every week.
How to Find Dead Stock in Lightspeed Retail
Lightspeed Retail gives you the sales and inventory data you need — you just have to know where to look.
- Pull an inventory report with last-sold date. This shows you when each SKU last had a sale, not just how much is on hand.
- Set a cutoff. Ninety days is a reasonable starting point. Tighter categories, like fresh or seasonal goods, may need a shorter window.
- Sort by dollar value, not just units. Ten dead $80 jackets matter more to your cash flow than fifty dead $2 items.
- Break it down by location. If you have more than one store, check each separately. A combined report can hide a problem that’s really only at one location.
- Cross-reference with vendor and category. Patterns often show up here — one vendor’s line consistently underperforming, or one category quietly piling up.
This process works, but it’s also exactly the kind of manual, repetitive task that eats up a manager’s week. That’s the gap tools like Retail Advisor by Octopus Bridge are built for — instead of building this report by hand, you can simply ask, “what hasn’t sold in 90 days?” and get a ranked answer in seconds.
How to Clear Dead Stock Once You’ve Found It
Finding it is half the job. Here’s how to actually move it.
Markdown strategically, not randomly. Start with the highest-dollar-value dead stock first — that’s where the cash is tied up. A tiered discount (25% at 90 days, 50% at 120 days) is easier to manage than one-off decisions.
Bundle it with fast sellers. Pairing a dead item with something popular can move it without a steep discount on its own.
Consider a vendor return. Some supplier agreements allow returns or exchanges for stock that hasn’t sold — worth checking before you write it off.
Use it as a loyalty or promotional offer. A free-with-purchase item still clears inventory and can build goodwill with regular customers.
Stop reordering it. This sounds obvious, but it’s the step that’s easiest to skip. If a product has been flagged as dead stock, take it off the standing reorder list until there’s a real reason to bring it back.
Preventing Dead Stock Going Forward
Clearing existing dead stock solves today’s problem. Preventing the next round takes a small change in routine:
- Review sell-through by category monthly, not just at season-end.
- Compare early sell-through on new seasonal buys against last year’s numbers before placing the next order.
- Watch for products that are reordered automatically without anyone checking recent sales first.
Quick Tip: If you’re doing this for the first time, don’t try to solve everything at once. Start with your top 20 dead-stock SKUs by dollar value — that’s usually where most of the tied-up cash lives.
The Bottom Line
Dead stock isn’t a sign you’re doing something wrong — it’s a normal part of running a retail business. What matters is catching it early and having a routine for clearing it, instead of finding out twice a year during a physical count.
If you want a faster way to spot it, Lightspeed Retail R and X series users can connect Retail Advisor and simply ask what hasn’t sold recently, instead of building the report by hand. For more on how AI fits into everyday retail decisions, see our complete guide to AI for Lightspeed Retail.
