How to Spot and Fix Slow Moving Inventory

Let's set the scene: You ordered what the forecast said you'd need. The trend looked solid, the numbers even made sense, and you were banking on this product being a smashing hit!

But then the unexpected happened: the trend suddenly shifted and customers just moved on to something else, maybe even a competitor undercut you. And now you're stuck with inventory collecting dust on a shelf and not being the cash cow you had hoped.

Sound familiar?

If you're staring at a slow-moving SKU wondering whether to wait it out, discount it, or cut your losses, you're facing one of the most common, and most expensive, problems in eCommerce.

A 2025 Netstock benchmark of supply chain planning found that more than half of surveyed brands held at least 20% excess slow-moving stock, with 5% eventually becoming dead stock.

That's not a one-off problem. Factor in storage, capital costs, and the risk of products becoming obsolete before they sell, and you've just created a black hole of margin loss and cash flow issues.

The good news: slow-moving stock is fixable, and it's rarely too late to do something about it.

What counts as "slow-moving inventory"?

There's really no universal cutoff, what counts as slow-moving depends entirely on your category and sales velocity. Most brands land somewhere between 90 and 180 days without a sale, though highly seasonal or trend-driven categories may set the bar even shorter.

The important part isn't the exact number - it's picking one and sticking to it. Work with your inventory or ops team to define your own slow-moving threshold early, so you're catching items before they slide into dead stock (inventory that's effectively unsellable) rather than after.

What's the difference between slow-moving inventory and dead stock?

Slow-moving inventory still sells, just more slowly than you'd like. Dead stock has stopped selling almost entirely and is unlikely to move without significant intervention like a steep markdown or liquidation. Every dead stock item was once a slow-moving item, which is exactly why catching it early matters: the earlier you act, the more options (and margin) you have.

Every dead stock item started as slow-moving inventory. The earlier you act, the more options, and margin, you keep.

How do I determine why my inventory isn't moving?

Before you discount or liquidate anything, figure out why the item isn't selling. The right fix lies in diagnosing the right cause.

Running a basket analysis of customer purchasing behavior can help answer:

• Who's buying it, if anyone? Is your targeting or merchandising reaching the right audience? If who you're targeting isn't scooping it up, then it might be time to re-evaluate and shake up the marketing.
• What do customers buy alongside it? If there's a natural pairing, a bundle might unlock the item's value more effectively than a standalone discount.
• Is it getting abandoned in-cart? If people are adding it and not checking out, the problem may be price, shipping cost, or product page information, not lack of interest.

How to clear slow-moving inventory (and keep it from coming back)

Based on what your basket analysis uncovered, one (or more!) of these strategies may be the key to getting your inventory back into active rotation, and your cash flow back on track.

1. Use targeted discounts and bundling

Discounting is one of the oldest tricks in the books, and one of the fastest ways to move slow inventory. It works because everyone comes out ahead: customers get a deal, and your warehouse gets space back.

If you want to turn up the heat, pair a slow-mover with a high-demand item in a bundle. This tactic can be even more effective than a standalone discount, since it lets you offload inventory without dropping your effective price as visibly.

2. Reposition through a different channel or audience

Sometimes a product isn't underperforming, it's just marketed to the wrong audience and a little creative spin could make all the difference in sell-through rates.

Case in point:

• An accessory item meant to help avid travelers stay organized on the go could be equally useful for busy parents too.
• A health product designed to help athletes recover quicker could also be marketed to an older audience wanting to starve off age related decline.
• A hair product traditionally marketed towards women could just as easily be marketed to men (we see you Tresemme)

Additionally, look into secondary sales channels to promote your products. Maybe your target audience hangs out on a different social platform than where you're currently focussing? Broadening your UGC scope could help you land in more niche markets.

3. Swap or liquidate through B2B channels

A 50% markdown that actually clears inventory beats a 100% write-off six months later. If discounting and repositioning haven't moved the needle, it's time to look outside your own storefront.

These tactics can help clear volume faster than selling excess inventory one by one:

• Sell to big-box off-price retailers like TJ Maxx, Marshalls, and Homegoods
• Sell to a closeout buyer, like Total Surplus Solutions and Lewisco Holding, who will purchase entire lots outwrite and redistribute them to non-competing secondary markets (like international outlets, live-stream sellers, independent markets, etc.)
• Engage wholesale buyers by creating a detailed inventory list and approach multiple buyers to negotiate the best deal.

4. Donate or give it away strategically

When an item won't sell or liquidate for meaningful value, giving it away can still generate a return, just not a direct one:

• Charitable donations (and maybe even get a tax-deductible write off)
• Social media giveaways to build engagement
• Free-gift-with-purchase once a customer hits a spending threshold
• Surprise inserts in outbound shipments, which can boost customer loyalty and repeat purchases

5. Fix the forecasting that created it in the first place

The most effective long-term fix isn't clearing slow-moving inventory, it's not overordering it to begin with.

Poor demand forecasting is consistently cited as the top cause of dead stock, which means better forecasting is the highest-leverage fix available. Review reorder points and purchase quantities against actual sell-through data regularly, rather than relying on last season's numbers or gut instinct, especially for trend-sensitive or seasonal categories.

The Best Fix Is Seeing It Coming

Every tactic in this guide works better the earlier you catch a slow-moving item.

Aa targeted discount lands harder in month two than month six, a bundle is easier to build before you've lost the sales data to know what pairs well, and liquidators pay more for inventory that hasn't been sitting for a year.

The real advantage is in knowing which SKUs are drifting before they've cost you real margin.

That's usually where the forecasting fix from earlier in this list breaks down for growing brands. Sell-through data, reorder points, and aging inventory reports often live in different systems, or don't get reviewed until a cash flow problem forces the conversation.

At Nice Commerce, our fulfillment team flags aging inventory and sell-through patterns before they become a cash flow problem, so you can act on tactics like these while you still have options, not after the window's closed.

Our 100% scan-based systems and high-tech WMS system allows us to spot inventory trends in real-time, giving you accurate data to make informed decisions quickly. If you need better visibility and accountability for your brand, we'd love to talk shop!

Frequently Asked Questions

What is slow-moving inventory?

Slow-moving inventory is stock that hasn't sold within a business's expected timeframe, typically 90-180 days depending on the product category and sales velocity.

What's the difference between slow-moving inventory and dead stock?

Slow-moving inventory still sells, just more slowly than expected. Dead stock has effectively stopped selling and is unlikely to move without a significant markdown or liquidation effort.

What does slow-moving inventory cost brands?

Beyond the money already spent to purchase it, slow-moving inventory eats into your margin through ongoing storage and handling fees, ties up cash that could otherwise fund new inventory or marketing, and takes up warehouse space that could hold products actually selling. Carrying costs alone typically run around 25% of the inventory's value annually, and that's before factoring in the eventual markdown needed to move it.

What percentage of inventory is typically slow-moving or dead stock?

Industry research estimates slow-moving inventory and dead stock occupy 20-30% of warehouse space at any given time across retail and eCommerce.

What causes slow-moving inventory?

Poor demand forecasting is the most commonly cited cause, though seasonal mismatches, overordering, and shifting customer trends also contribute.

Is discounting or liquidating better for slow-moving inventory?

Start with discounting or bundling, since it preserves more margin. Move to liquidation or B2B trade only if targeted discounts and repositioning haven't moved the product within a reasonable window.
