Preventing slow-moving inventory: SKU reviews and reorders

Preventing slow-moving inventory comes down to two habits: reviewing every SKU on a fixed schedule, and setting reorder quantities from real demand and lead time rather than supplier minimums or optimism. Catch drift early and you can fix price, listing or channel long before overstocks need liquidation or a removal order.

Why excess inventory builds up

Overstocks rarely come from one bad decision. They build from forecasts that ignore seasonality, minimum order quantities larger than demand, launches that underperform, and reorders placed on autopilot after demand has slowed. Each extra unit carries storage cost, ties up cash and ages toward marketplace surcharges. Prevention is also the strongest sustainability lever available: EPA ranks source reduction, also called waste prevention, as the most environmentally preferred strategy, ahead of recycling and disposal.

Run a monthly SKU review

Metrics to track per SKU

• Days of supply: how many days current units will last at projected demand. Amazon's Restock Inventory tool reports this figure.
• Sell-through: units sold in the period divided by units available.
• Inventory age: how long units have been on hand. Walmart's Inventory health report treats ATS 271-365 days as close to its long-term storage fee.
• Open purchase orders: units already on the way that will add to supply.

Flags that need action

Watch for days of supply far beyond lead time plus a reasonable safety buffer, sell-through falling for two or more consecutive periods, units entering the age band before a storage surcharge, and SKUs with no sales in the last 60 or 90 days. Pick thresholds that fit your category and keep them consistent so trends stay visible.

Reorder against demand, not habit

Amazon's Restock Inventory tool bases its recommendations on sales history, demand forecast, seasonality and replenishment settings such as lead time, case pack quantity and replenishment frequency. It flags low stock when days of supply fall below lead time. The same logic works in any channel: reorder when projected supply will run out within lead time, and order enough to cover the next cycle plus a safety buffer, nothing more.

Three practical rules help. First, update lead times whenever a supplier changes, because stale lead times cause both stockouts and panic over-orders. Second, challenge minimum order quantities: a lower unit cost on units you cannot sell is not a saving. Third, taper reorders for seasonal and end-of-life SKUs ahead of time instead of reordering at full volume.

Act early on slow movers

When a SKU is flagged, work through options in order of value retained: price adjustments, listing improvements, bundling, moving units to another channel, and finally a planned exit through liquidation or a resale partner before age-based fees apply. Walmart's own guidance follows the same order, suggesting pricing, listing quality, ads and Multichannel Solutions before removal. Selling earlier usually means more buyers and more resale channels, which keeps products in use.

Slow-moving inventory checklist

• Hold the SKU review on the same day each month.
• Track days of supply, sell-through, age and open orders per SKU.
• Keep lead times and case pack quantities current in your planning tools.
• Review minimum order quantities against forecast demand.
• Set an exit trigger for each SKU before you reorder it.
• Choose the exit route before age-based fees start.

FAQ

How often should I review SKUs?

Monthly suits most catalogs. Fast-moving or seasonal categories may need weekly checks during peak periods.

When should I stop trying to sell through?

When the discount or ad spend needed to move a unit exceeds what a planned exit would recover, or when age-based fees are close. Our guides to Amazon FBA removal options and Walmart WFS removals cover the next steps.
