How to Manage Aged Inventory & Reduce Long-Term Storage Fees
Watching your products gather dust in an Amazon warehouse is painful for any seller. Not only does it tie up your capital, but it also racks up costly aged inventory surcharges that can silently destroy your profits. The key to a healthy FBA business is keeping your products moving. But what do you do when they don’t?
To effectively how to manage aged inventory and reduce long-term storage fees, you must combine proactive sales strategies like promotions and listing optimization with Amazon’s clearance programs, while implementing smart, data-driven inventory planning to prevent overstock in the first place. This guide provides a complete playbook covering everything from quick promotional tactics to long-term strategic planning to turn stale stock into cash flow and keep your account in good standing.
Proactive Strategies to Sell Through Stock Faster
The best way to deal with aging inventory is to prevent it from getting old in the first place. These strategies focus on increasing your sales velocity to move products before they become a problem.
Repricing to Increase Sell Through
One of the most direct ways to boost sales is to adjust your price. By strategically lowering your price or using dynamic repricing tools, you can make your offer more competitive and attract bargain hunters. A lower price is often the key to winning the Amazon Buy Box, which accounts for a staggering 80 to 85% of all customer purchases. While you need to be careful not to start a price war that erodes margins, a calculated discount is often better than paying indefinite storage fees.
Running Sponsored Ads and Coupon Promotions
A powerful one two punch for moving stock is combining Amazon PPC ads with coupons. Sponsored Ads push your product to the top of search results, getting more eyes on your listing. The coupon, that little green badge showing a discount, provides a compelling reason for shoppers to click and buy. The ad drives the traffic, and the coupon converts it. This combination is especially effective for slow moving items, as it can create the sales momentum needed to improve your product’s organic ranking over time.
Improving Your Listing (Keywords, Title, Images)
Sometimes, a product doesn’t sell simply because the listing isn’t doing its job. Optimizing your product listing is fundamental. This means:
- Keywords: Researching and including relevant search terms in your title, bullet points, and backend search fields so customers can find you.
- Title: Crafting a clear, informative title that includes top keywords and key benefits.
- Images: Using all available image slots with high resolution photos that showcase your product from every angle, in use, and even with infographics.
A well optimized listing gets more traffic and converts more visitors into buyers. For example, adding A+ Content (rich media content for brand registered sellers) has been shown to boost sales by an average of 5 to 10%. Effective listing optimization is a core part of learning how to manage aged inventory and reduce long-term storage fees because it increases your natural sell through rate.
Creating Virtual Product Bundles
If you’re a brand registered seller, you can use Amazon’s virtual bundle tool to sell two to five complementary products together without physically packaging them. When a customer buys the bundle, Amazon picks and ships each individual item from your FBA inventory. This is a brilliant way to pair a slow selling item with a popular one, increasing the slow mover’s exposure and sales. It’s a low effort, high impact strategy to increase your average order value and clear out sluggish stock.
Bundling or Repackaging Slow Movers
Similar to virtual bundles, you can physically bundle a slow moving product with a more popular one or create a multi pack to offer a better value proposition. For instance, if a specific phone case isn’t selling, you could bundle it with a charger or sell a three pack at a discount. This changes the customer’s perception of value and can stimulate demand. It’s a creative way to reposition a product that would otherwise become aged inventory.
Using Amazon’s Programs for Clearance
If promotions and listing tweaks aren’t enough, Amazon provides official channels to help you clear out overstock inventory.
Running an Amazon Outlet Deal
Amazon Outlet is the official clearance section of the site, and running an Outlet Deal places your overstock product in front of bargain hunting shoppers. To be eligible, your product usually needs to be in FBA for at least 90 days and have a decent star rating. The results can be dramatic. According to Amazon, sellers who participated in Outlet deals saw their units sold increase by an average of 93% in the four weeks following the deal. It’s a free program to participate in (you just cover the discount) and an excellent way to turn excess units into cash.
Using the FBA Liquidation Program
When you need to recover some value from inventory that simply won’t sell, the FBA Liquidation Program is a solid option. Instead of paying to have your items disposed of, Amazon sells your stock in bulk to wholesale liquidators on your behalf. You typically receive a net recovery of around 5 to 10% of the item’s average selling price. While it’s a small fraction of the original value, it’s far better than getting nothing and continuing to pay storage fees. This program is a crucial safety valve for FBA sellers.
The Last Resort: Removal and Disposal
For some products, the most financially sound decision is to cut your losses and get them out of Amazon’s warehouses.
Removing or Disposing of Aging Inventory
You can create a removal order to have Amazon ship aging inventory back to you, or a disposal order to have Amazon get rid of it. Both options come with a per unit fee, but this one time cost is often much lower than the mounting aged inventory surcharges. For example, after 365 days, Amazon charges an extra monthly fee of $6.90 per cubic foot or $0.15 per unit, whichever is greater. Paying a small removal fee to avoid these crippling costs is a smart business decision. This is a critical tactic for how to manage aged inventory and reduce long-term storage fees.
Setting Up Automated Removals
To avoid having to manually create removal orders, you can configure automated removals in your FBA settings. You can set rules to automatically remove unsellable inventory (like damaged returns) or aged inventory. By default, Amazon automatically removes inventory that has been in a fulfillment center for over 365 days. You can customize these settings to have items returned to you or disposed of on a schedule that works for your business, ensuring you never get caught off guard by long term fees.
Why to Avoid the “Remove and Restock” Loophole
Some sellers in the past tried to game the system by removing aging inventory right before fees were charged, only to immediately send it back in. This “loophole” no longer works and is a bad idea. Amazon now assesses aged inventory fees monthly, making the timing trick ineffective. Furthermore, this practice doesn’t solve the root problem (a product that isn’t selling) and costs you money in removal and inbound shipping fees. Focus on genuinely improving sell through or permanently removing the stock.
The Foundation: Smart Inventory Planning and Monitoring
The ultimate way to win the battle against aged inventory is through disciplined planning and constant monitoring.
Forecasting Demand Accurately
Demand forecasting is the process of using historical sales data, seasonality, and market trends to predict how many units you’ll sell in the future. Accurate forecasting helps you avoid both overstocking and understocking. It’s about sending the right amount of product at the right time. Strong forecasting is the foundation for learning how to manage aged inventory and reduce long-term storage fees.
Maintaining a 90 to 180 Day Inventory Cover
As a general rule, aim to keep about 3 to 6 months of inventory in FBA. This is often called a 90 to 180 day inventory cover. This range provides a healthy buffer to prevent stockouts while minimizing the risk of units sitting long enough to incur aged inventory surcharges. In fact, Amazon’s systems often flag inventory with more than 90 days of supply as “excess,” which can hurt your performance metrics.
For businesses looking to master this balance, working with experts can be a game changer. An experienced team like EZCommerce can implement disciplined restock schedules and aged inventory alerts to keep your stock within that optimal 3 to 6 month window.
Shipping Smaller, More Frequent Shipments
Instead of sending a huge, six month supply of inventory to FBA at once, switch to sending smaller batches more frequently. Shipping inventory every few weeks keeps your on hand stock levels lean, improves your cash flow, and dramatically reduces the risk of incurring long term storage fees. This “just in time” approach gives you more flexibility to react to changes in demand and is a cornerstone of modern FBA inventory management.
Prioritizing High Velocity SKUs for FBA
Focus your FBA storage space and capital on your fastest selling products. These high velocity SKUs are your winners, and you should ensure they are always in stock with Amazon to capture Prime sales. Amazon’s algorithms reward sellers who keep their popular items in stock. By prioritizing these SKUs for FBA, you maximize your most profitable sales and improve your overall account health.
Switching Slow Movers to FBM or Alternate Storage
For products that sell very slowly, using FBA may not be profitable. The storage fees can easily eat up any margin you make. A smart solution is to switch these items to Fulfilled by Merchant (FBM). You store the products yourself or with a cheaper third party logistics (3PL) partner and ship orders as they come in. This approach is ideally aligned with your D2C growth program so inventory and merchandising stay in sync.
Using Amazon’s Tools to Stay Ahead
Amazon provides a suite of reports and dashboards to help you monitor your inventory health. Using them effectively is non negotiable.
Monitoring the Inventory Health Dashboard
Your Inventory Health or Inventory Performance dashboard in Seller Central is your command center. It gives you a snapshot of key metrics like your Inventory Performance Index (IPI) score, sell through rate, excess units, and stranded inventory. Make it a habit to check this dashboard weekly to identify potential problems before they escalate.
Identifying At Risk Inventory
Within your inventory reports, Amazon flags units that are “at risk” of incurring aged inventory surcharges. This is your early warning system. When you see this flag, it’s a signal to take immediate action, whether that’s launching a promotion, creating an Outlet Deal, or planning a removal order.
Checking the Aged Inventory Surcharge Report
This report is your itemized bill for storage penalties. It shows you exactly which SKUs were charged aged inventory fees and how much they cost you. If you suspect inaccuracies, run an FBA fee audit and recover overcharges. While the report is backward looking (the money is already gone), reviewing it monthly helps you identify consistently problematic products so you can avoid the same fees next month.
Checking and Fixing Stranded Inventory
Stranded inventory is stock sitting in an FBA warehouse that isn’t available for sale due to a listing issue. You are paying storage fees on units that have zero chance of selling. You can find stranded inventory in your Inventory Health dashboard. Fixing it is often as simple as clicking a “relist” button or updating a minor detail on the product page. Check for and resolve stranded inventory weekly.
The Big Picture: Maintaining a Healthy Account
All of these strategies tie into one critical metric: your IPI score.
How to Maintain a Healthy IPI Score
Your Inventory Performance Index (IPI) is a score from 0 to 1000 that measures your FBA inventory efficiency. A healthy score is anything above 400. Falling below this threshold can result in storage volume limits, preventing you from sending in enough stock during peak seasons.
To maintain a healthy IPI score, you must:
- Reduce excess inventory: Actively clear out overstock.
- Improve your sell through rate: Use promotions and ads to move products faster.
- Fix stranded inventory: Ensure all your FBA units are buyable.
- Keep popular items in stock: Avoid stocking out on your best sellers.
Effectively managing your inventory is a continuous process, not a one time fix. By combining promotional tactics with smart planning and diligent monitoring, you can master how to manage aged inventory and reduce long-term storage fees, improve your profitability, and grow your Amazon business sustainably.
If you are struggling to balance inventory levels or your IPI score is trending downward, it might be time to bring in a professional team. An agency specializing in Amazon growth can provide the strategy and execution needed to optimize your entire FBA operation.

Frequently Asked Questions
What is the first step to manage aged inventory and reduce long-term storage fees?
The first step is to identify the problem. Log in to Amazon Seller Central and navigate to your Inventory Health dashboard. Look at the “Inventory Age” breakdown to see which of your SKUs have been sitting the longest and are at risk of incurring fees.
How often should I check my inventory age?
You should review your inventory age and overall inventory health at least once a week. This allows you to catch slow moving products early and take proactive steps, like launching a sale or ad campaign, before they become a significant cost.
Is using the FBA Liquidation program better than creating a removal order?
It depends on your goals. Liquidation allows you to recover a small percentage of the product’s value (typically 5 to 10%) without having to handle the physical inventory. A removal order costs you a fee per item, but you get the product back, which you can then try to sell on other channels or bundle. If the product has no resale value for you, liquidation is often the better financial choice.
Can improving my product listing really help reduce storage fees?
Absolutely. A fully optimized listing with strong keywords, compelling images, and clear bullet points can significantly increase your conversion rate and sales velocity. When products sell faster, they spend less time in the warehouse, which directly reduces your monthly storage fees and prevents them from becoming aged inventory in the first place.
What is a good IPI score to aim for?
The minimum threshold for a healthy IPI score is 400. However, you should aim to be well above that, ideally in the 500 to 800 range. A higher score indicates a very efficient inventory system and gives you a comfortable buffer against any unexpected dips.
How do I know how much inventory to send to FBA?
This comes down to demand forecasting and maintaining a target inventory cover. Analyze your last 30 to 90 days of sales for a given product to project future demand. A great starting point is to aim to keep between 90 and 180 days of stock in FBA, sending smaller, more frequent shipments to maintain that level.
What is the most common cause of stranded inventory?
One of the most common causes is an inactive or closed listing. This can happen accidentally if you’re editing your product catalog or if Amazon suppresses the listing for a compliance issue. Regularly checking the “Fix Stranded Inventory” page is the best way to catch and resolve these problems quickly.
Is it worth it to switch a slow selling product to FBM?
For many slow sellers, yes. While you might lose the Prime badge, the savings on FBA storage fees can be substantial, especially for larger items or products that sell only a few units per month. Switching to FBM is a key strategy for any seller looking at how to manage aged inventory and reduce long-term storage fees.
