Amazon FBA sellers lose 1% to 3% of inventory annually to discrepancies like lost items, damaged products, and fee errors. For a $1M business, that’s $10,000–$30,000 gone every year. The good news? Many of these losses are recoverable if you act quickly and stay organized.
Key Issues to Watch Out For:
Missing Items During Shipping – Lost inventory during transit.
Damaged Products in Warehouses – Mishandling or poor storage.
Lost Items in Warehouses – Misplaced or unaccounted stock.
Untracked Customer Returns – Refunds without items being returned.
Unauthorized Disposal – Items disposed of without your consent.
FBA Fee Errors – Overcharges from incorrect dimensions or weights.
Wrong Size and Weight Charges – Inflated fees from measurement mistakes.
Mixed Inventory Problems – Counterfeit or low-quality items from commingling.
Missing Multi-Channel Orders – Tracking issues across platforms.
Stuck Inventory – Unsellable items due to listing or pricing errors.
Quick Action Plan:
Document Everything: Keep records of shipments, sizes, and weights.
Audit Regularly: Use tools like Amazon reports or automated services.
File Claims Fast: Stay within Amazon’s claim windows (e.g., 9 months for lost items).
Prevent Issues: Fix packaging, labels, and inventory tracking systems.
Why It Matters:
Recovering lost funds can save thousands of dollars annually. Tools like Refunzo automate reconciliation and make it easier to claim reimbursements. Don’t leave money on the table - act now to protect your profits.
How to Request Reimbursements from Amazon FBA for Lost & Damaged Units
1. Missing Items During Shipping to Amazon
When inventory goes missing during transit to Amazon FBA centers, it can hurt your business through lost sales and reduced inventory value. For example, if you ship 1,000 units but Amazon only logs 980, those 20 missing units mean lost revenue. Here's how to protect your shipments and simplify reimbursement claims.
Document Everything Before Shipping
To minimize issues, keep detailed records of your shipments:
Take photos of the boxes.
Record the exact product quantities.
Save all shipping labels and tracking numbers.
Hold onto packing lists that detail the contents.
Actively Track Shipments
Use the Shipping Queue in Seller Central to stay updated on your shipment's progress. The Shipment Events tab provides a clear view of your inventory's journey, from shipment creation to delivery.
Reconciliation Process
If items go missing, you'll need specific documents to start the reconciliation process:
Shipment ID
Proof of ownership
Tracking information
Delivery confirmation
Automated tools like Refunzo can make this easier. Their system runs a 21-point check to find discrepancies and flags missing inventory for you. You can either file claims yourself or let them handle it for a capped fee of $5,000.
Key Timeframes to Know
If you notice missing items, check the Contents tab in your shipping plan to compare what you sent with what the fulfillment center received. Before filing a claim, review your Reimbursements report to ensure you haven’t already been compensated.
2. Products Damaged in FBA Warehouses
Damaged inventory in Amazon's fulfillment centers can hurt your profit margins. While Amazon's Multi-Channel Fulfillment (MCF) claims a 99.98% undamaged package delivery rate, incidents still happen. Here's how you can spot, document, and claim reimbursement for damaged items.
Common Causes of Damage
Damage to products often happens during warehouse operations due to:
Poor storage conditions
Mishandling during picking and packing
Issues in the fulfillment process
Frequent handling increases the risk of damage, so using protective packaging and staying on top of monitoring are key.
How to Detect and Document Issues
To minimize losses, focus on early detection and thorough documentation:
Review Reports Regularly
Check Seller Central reports like Inventory Adjustments, Reconciliation, and Returns to identify potential damage.
Take Preventive Steps
Protect your inventory by:
Using proper packing materials for fragile items
Securing heavy items appropriately
Clearly labeling fragile products
Filing Claims: What You Need to Know
As of October 23, 2024, sellers have a 60-day window to file claims. Follow these steps:
Gather evidence of the damage
Keep detailed records
Submit claims within the 60-day period
Include photos and supporting documentation
Automating the Process
Automated tools can simplify tracking inventory, flagging damages, and generating claims reports. These tools can save time and ensure no damage goes unnoticed.
How Compensation Works
Amazon calculates reimbursements based on fair market value, recent sales data, comparable listings, and applicable FBA fees. Acting quickly to address damaged inventory helps you recover losses and protect your bottom line.
3. Lost Items in Amazon Warehouses
Lost inventory in Amazon warehouses can quietly eat into your profits, often accounting for 1% to 3% of total sales. Knowing how to track and recover these losses is key to keeping your profit margins intact.
Why Does Inventory Get Lost?
Items can go missing due to warehouse misplacement, scanning errors, system glitches, or handling mistakes. These issues might seem small but can add up quickly.
How to Track Missing Inventory
Amazon's Inventory Adjustment Report is your go-to tool for spotting lost items. It uses reason codes to highlight issues like missing shipments, reconciliation errors, or unaccounted adjustments. Identifying these problems early gives you a head start on recovering your losses.
Using Automated Tools
Tools like Refunzo can automate the process, running 21-point checks to identify lost items and delivering detailed reports to streamline your efforts.
Steps to File Reimbursement Claims
If you find lost inventory, here’s how to file a reimbursement claim:
Gather Documentation
Collect everything Amazon might need, such as shipping manifests, adjustment reports, transaction histories, and cost details.
Submit Your Claim
File your claim through Seller Central. Be thorough - include a clear explanation, supporting documents, ASIN details, and shipment IDs.
Follow Up
Keep an eye on your case. Respond quickly to Amazon's requests, provide any extra documentation, and appeal decisions if needed.
How Successful Are Reimbursement Claims?
In March 2023, services like Getida reported a 63% approval rate for claims. While not guaranteed, these numbers show that persistence pays off.
Tips to Prevent Inventory Loss
Minimize losses by adopting these practices:
Perform weekly audits
Cross-check reports regularly
Use scannable labels for accuracy
Take photos of your shipments
Keep a detailed tracking spreadsheet
Don’t Miss the Deadline
Amazon gives you an 18-month window to file claims for lost inventory. Acting quickly when you notice discrepancies increases your chances of getting reimbursed. Stay proactive!
4. Untracked Customer Returns
If you're not keeping an eye on customer returns, they can quietly eat into your profits. These unnoticed issues can create gaps in your records and hurt your earnings. Here's a closer look at common problems, their financial impact, and how to address them.
Common Return Tracking Problems
When customers send items back to Amazon FBA warehouses, a few things can go wrong:
Amazon often doesn't notify sellers when an item is returned to an FBA warehouse.
Standard reports might only show returns after they're fully processed, causing delays.
Warehouse staff may misjudge the condition of returned items, restocking damaged products as sellable.
Sometimes, returns show up after Amazon's 30-day return window due to processing delays.
The Cost of Untracked Returns
Returns that take longer than 45 days to process or refunds issued without receiving the item back can lead to major revenue losses.
How to Stay on Top of Returns
Amazon's Return Insights tool can help you catch potential issues early. Found under "Manage FBA Inventory", this tool lets you track:
Patterns and trends in returns
Delays in processing
Mishandled items
Missing reimbursements
Steps to Handle Discrepancies
Monitor and Document
Regularly compare return notifications with your inventory records. Use the FBA Customer Returns Report in Seller Central to keep track of details like:Reasons for returns (Amazon has 72 official categories)
Processing status
Condition of returned items
Eligibility for reimbursements
File Claims
If you spot a discrepancy, file a claim through Seller Central immediately. Make sure to include clear evidence.
How to Avoid Future Problems
Taking proactive steps can help you minimize future return-related losses:
Review return reasons regularly to spot patterns and improve your products.
Check your packaging to reduce the risk of damage during shipping.
Share feedback with suppliers to address recurring quality issues.
Don't Miss Out on Reimbursements
Amazon limits single-item reimbursements to $5,000, so it's especially important to monitor high-value returns. Tools like Refunzo can help by offering a free lifetime reconciliation service with a 21-point system, ensuring you recover every dollar you're owed.
5. Items Disposed Without Permission
Amazon's disposal of inventory without your consent can quietly eat into your profits. It's important to recognize the common scenarios and take steps to safeguard your investment.
Common Disposal Scenarios
Keep these situations in mind during your inventory audits:
Items flagged for safety or health concerns
Products missing required hazardous materials documentation
Inventory deemed unfulfillable for over 60 days
Items subject to recalls that aren't resolved within 30 days
The Cost of Auto-Disposal
Automated settings in Seller Central can lead to unexpected losses. The automated unfulfillable setting often defaults to "dispose" instead of "return", which can result in inventory being discarded without your knowledge.
Signs to Watch For
Amazon does send notifications before disposing of inventory, but these alerts aren't always reliable. Keep an eye out for these warning signs:
30-day email alerts and 5-day final notices
Sudden inventory adjustments
Unexplained changes in stock levels
Documentation You Need
Proper documentation can help you validate your inventory and support claims. Use the following records:
Document Type | Purpose | Key Details to Include |
|---|---|---|
Purchase Orders | Proof of ownership | Quantities, dates, and costs |
Shipping Records | Delivery verification | Tracking numbers and receipts |
Inventory Reports | Stock tracking | Regular inventory snapshots |
Product Documentation | Compliance proof | Safety certificates, Hazmat approvals |
How to Secure Reimbursement
If Amazon disposes of your inventory in error, you may qualify for reimbursement. Here's what to do:
Check that the disposal wasn't due to a policy violation.
Collect evidence showing proper inventory management.
Submit your claim within the required timeframe.
Follow up consistently for 30-45 days.
Good documentation and timely claims are key to recovering losses.
Preventing Future Issues
Avoid costly mistakes by staying proactive:
Regularly review your automated disposal settings.
Ensure hazardous materials documentation is current.
Monitor inventory reports for discrepancies.
Set reminders for the 60-day unfulfillable threshold.
Tools like Refunzo's free reconciliation service can help by performing automated checks to catch disposal issues early and protect your bottom line.
6. FBA Fee Calculation Errors
FBA fee calculation errors can quietly eat into your profits. Like other inventory issues, these errors often go unnoticed, gradually affecting your margins. On average, unrecovered Amazon FBA fee reimbursements can account for up to 3% of annual revenue.
Common Fee Overcharges
Here are some of the most frequent errors and their impacts:
Error Type | Impact | Detection Method |
|---|---|---|
Dimension Mismatches | Higher storage and shipping fees | Regular Cubiscan verification |
Weight Discrepancies | Increased fulfillment costs | Physical product measurement |
Category Misclassification | Incorrect referral fees | Category audit |
Storage Fee Miscalculations | Extra monthly charges | Inventory report analysis |
Identifying Fee Discrepancies
"Amazon charges sellers FBA fees based on the dimensions and weight of their products. These fees cover storage, picking, packing, and shipping. Errors in logging dimensions or weights can lead to inflated fees."
To catch these issues, keep an eye on your monthly FBA Fee Reports. Verify product dimensions and weights using tools like Cubiscan at least twice a year. Implement SKU tracking to quickly identify any inconsistencies.
Recovery Process
If you spot fee errors, follow these steps to recover your money:
Document the correct product specifications.
Collect evidence of overcharges from your FBA reports.
Submit claims within the 90-day window.
Track each case until it’s resolved.
Prevention Strategies
Avoid future errors by taking these precautions:
Double-check product dimensions and weights when listing items.
Ensure categories are assigned correctly to avoid referral fee mistakes.
Review return-related fees for accuracy.
Regularly audit storage fee calculations.
Automated Solutions
Fee analysis tools can save you time and effort. Services like Refunzo’s free reconciliation tool automatically flag fee discrepancies, helping you address errors early.
Amazon’s reimbursement system works best when you provide clear, accurate evidence and stay persistent. Regular monitoring and quick action on fee issues can protect your profit margins. Incorporating fee audits into your routine ensures you’re not leaving money on the table.
7. Wrong Size and Weight Charges
Size and weight errors can quietly chip away at FBA profits, often leading to losses of 1%-3% without sellers even realizing it.
Common Measurement Issues and Their Impact
Amazon's system sometimes misclassifies product dimensions, leading to inflated fees. For instance, one seller's ASIN was recorded at 21.3 x 16.69 x 7.01 inches instead of its actual size of 14.57 x 11.42 x 6.89 inches. This kind of mistake can push items into higher fee tiers due to the US dimensional weight factor of 139.
How to Spot and Verify Errors
Getting your product measurements right is key to avoiding unnecessary fees and protecting your profit margins. Here’s how you can identify and address these issues:
Download the Fee Preview report.
Compare your product's actual dimensions with Amazon's recorded data.
Document any errors with clear photos.
Use tools like AMZAlert to verify dimensions.
Filing a Claim
"Sellers now have 90 days from the date a fee was charged to gather the required documentation and ask Amazon to investigate whether its measurements of a product are accurate." - News_Amazon
When you notice a discrepancy, you’ll need to act quickly. Submit your claim with all the necessary documentation and follow these steps to ensure a smooth process.
Steps for Resolution
Amazon allows up to 20 remeasurement requests each month. Here’s what you should do:
Take clear photos of your product on a scale and next to a measuring tape.
Submit your claim within the 90-day window.
Keep track of your case ID and respond promptly to any follow-up requests.
If your claim is approved, Amazon will refund the overcharges and update the product's measurements.
Preventing Future Issues
To minimize future problems, focus on packaging and record-keeping. Make sure to:
Design packaging that fits Amazon’s size tiers.
Keep accurate records of your product dimensions (length, width, height), unit weight (including packaging), and dimensional weight calculations.
Regularly reviewing your data and acting quickly when discrepancies arise can go a long way in protecting your profits. This is especially important since 73% of Amazon sellers rely on FBA.
8. Mixed Inventory Problems
When Amazon combines your products with those from other sellers, it can lead to financial losses and tracking headaches. These "commingled inventory" issues might seem minor, but they can quietly eat into your profits if left unchecked.
What Are the Risks of Commingled Inventory?
If you use manufacturer barcodes instead of Amazon-specific labels, your products join a shared inventory pool. While this might simplify logistics, it opens the door to several problems that can directly affect your business.
Risk Factor | Potential Impact |
|---|---|
Counterfeit Products | Account suspension and damage to your brand's reputation |
Quality Control | Difficulty verifying product authenticity and condition |
Inventory Tracking | Inaccurate stock levels |
Customer Trust | Dissatisfied customers due to counterfeit or defective items |
How It Can Hurt Your Finances
These risks don't just create logistical headaches - they can hit your wallet hard. Here's how:
Lost sales from bad reviews
Costs tied to account suspensions
Damage to your brand's reputation
Increased customer service expenses to address complaints
How to Avoid These Issues
Enroll in Amazon Brand Registry
This program gives you more control over your listings and helps block counterfeit products.
Leverage Amazon Project Zero
Use this tool to identify and remove counterfeit listings before they harm your brand.
Stick to Amazon-Specific Labels
Label your products with unique Amazon barcodes to keep them separate and ensure quality control.
Tips for Better Inventory Management
Regularly check inventory levels using Amazon's reporting tools.
Keep detailed records of product specs and authenticity markers.
Track shipments carefully and maintain thorough documentation.
Quickly address any customer concerns about product authenticity.
9. Missing Multi-Channel Orders
Handling inventory across multiple sales channels can lead to tracking issues and costly errors. Retailers face a staggering $634 billion loss each year due to out-of-stock items, while overstocks account for $471.9 billion in losses. These problems often stem from disconnected systems and inconsistent inventory updates.
Why Orders Go Missing
The main culprits behind missing orders include poor system integration and syncing errors. Specific issues like selling outdated stock, delays in order fulfillment, and incorrect inventory counts are common.
How to Fix Tracking Issues
The key to solving these problems lies in using a centralized system that connects all your sales channels. Tools like Sellbrite are designed to help with listing management, inventory syncing, and order fulfillment across platforms.
Real-time inventory updates are a game-changer. They prevent overselling and keep stock levels accurate. Emily Rohr, Founder of Rohr Remedy, shares her experience:
"In using TradeGecko, we've definitely reduced the amount of time we spend on inventory, and that's made a massive difference in us being able to supply our customers. We're getting more orders because we're more streamlined."
With the right tools, you can minimize errors and recover lost revenue more efficiently.
Steps to Recover Lost Revenue
If you’ve already lost revenue due to missing orders, here’s how to address it:
Keep detailed records of purchases and shipping documents.
Regularly check shipping queues to spot missing items.
Go to the 'Manage FBA Shipments' page and choose 'Reconcile' to file a reimbursement claim.
Provide purchase invoices (with pricing details removed) as proof to support your claim.
You can also use automated reconciliation tools to speed up this process.
Tips to Prevent Future Issues
Use CSV templates to update product data consistently across all channels.
Set up clear communication protocols between departments.
Adopt integrated shipping solutions to streamline order fulfillment.
Regularly review and refine your inventory management strategies.
10. Stuck Inventory Issues
Stranded inventory in Amazon FBA warehouses can lead to extra storage fees and missed sales opportunities. This happens when items become unsellable due to listing or fulfillment errors.
Common Causes of Stuck Inventory
There are several reasons why inventory might get stuck:
Listing Errors: Missing or incorrect product details.
Pricing Problems: Items priced outside Amazon's allowed range.
Restricted ASINs: Products flagged as restricted upon arrival.
Account Suspensions: Temporary restrictions on your selling account.
Product Expiration: Items nearing or past their expiration date.
These issues not only block sales but also increase storage costs and operational expenses. If stranded inventory isn’t resolved within 30 days, Amazon may remove or dispose of it automatically. This can hurt your Inventory Performance Index (IPI) and limit your future storage capacity.
Financial Impact and Prevention
Addressing stranded inventory quickly is essential to avoid losing revenue. Here’s how you can stay ahead:
Monitor Daily: Regularly check the "Fix Stranded Inventory" section in Seller Central.
Adjust Settings: Configure automatic actions to "Return units to me" instead of disposal.
Track Key Details: Keep records of expiration dates, compliance requirements, pricing limits, and reconciliation reports.
Recovery Process
If you identify stranded inventory, take these steps:
Check the Stranded Inventory Report to pinpoint the issue.
Resolve the problem within 30 days.
Document actions taken for potential reimbursement claims.
For more complex situations, consider using automated tools like Refunzo’s 21-point reconciliation checks to uncover reimbursement opportunities.
Best Practices for Prevention
To reduce the chances of inventory getting stuck, follow these tips:
Conduct thorough research before listing any product.
Double-check listing details before shipping items to FBA.
Keep product prices within Amazon’s allowed range.
Maintain active listings even when stock runs out to handle returns.
Set up alerts for listing issues to catch problems early.
Proactive management can save you time, money, and effort while keeping your inventory in good standing.
