If you sell on Fulfillment by Amazon (FBA), there’s a good chance that Amazon owes you money. Inventory gets lost, damaged, or mishandled, fees are miscalculated, and customer refunds don’t always match up. While Amazon does reimburse sellers for these mistakes, they won’t always do it automatically—which means you could be losing hundreds or even thousands of dollars without realizing it.
The problem? Filing FBA refund claims manually can be frustrating and time-consuming. Amazon’s system is complex, its policies have strict deadlines, and if you don’t follow the correct steps, your claim could get rejected.
The good news? Getting your money back doesn’t have to be a headache. This guide will walk you through a simple, step-by-step process to identify missing refunds, file claims the right way, and ensure Amazon pays you what you're owed—without the hassle. Whether you’re a new seller or an experienced one, this guide will help you maximize your reimbursements with minimal effort.

Common reasons Amazon owes you a refund
Amazon FBA handles millions of transactions and inventory movements daily, and with such a massive system, mistakes happen frequently. Whether it’s lost inventory, incorrect refunds, or overcharged fees, these errors can cost sellers money if they’re not identified and claimed in time.
Here are the most common reasons Amazon might owe you a refund:
1. Lost or misplaced inventory
Amazon regularly loses inventory inside its fulfillment centers, during warehouse transfers, or when receiving inbound shipments. If a product goes missing and Amazon fails to reimburse you automatically, you may be eligible for a refund.
2. Damaged inventory
Amazon staff may damage your products while handling or storing them. If they damage inventory inside their warehouse, they should reimburse you for the lost value. However, some cases slip through the cracks, requiring sellers to file a claim manually.
3. Overcharged FBA fees
Amazon charges fulfillment fees based on your product’s weight and dimensions, but sometimes, they incorrectly measure your items, leading to higher fees than necessary. If Amazon overcharges you for fulfillment or storage, you’re entitled to a refund.
4. Customer refund errors
Amazon issues a refund to a customer but the item is never returned to your inventory.
A buyer returns a completely different product, but Amazon still deducts the refund from your account.
Amazon refunds a customer twice for the same order.
If any of these happen, Amazon owes you money, and you’ll need to file a claim.
5. Inbound shipment discrepancies
When you send inventory to Amazon, they’re supposed to receive and check in the correct quantity. However, Amazon sometimes:
Receives fewer units than what you sent.
Fails to update your inventory count correctly.
Misplaced your inventory during check-in.
If this happens, you can claim Amazon FBA reimbursement for the missing units.
6. Destroyed or disposed-of inventory
Amazon sometimes removes, destroys, or marks inventory as unsellable without seller approval. If this happens and they haven’t issued a refund, you have the right to claim one.
7. Issues with removal orders
When you request a removal order to have inventory returned to you, Amazon may not send back the correct number of units or might lose items in transit. If your removals don’t match what Amazon recorded, you should file for a refund.
How to check if Amazon owes you a refund
Amazon’s FBA system isn’t perfect, and mistakes happen—whether it’s lost inventory, incorrect fee charges, or customer returns that weren’t reimbursed. Before you claim a refund, you need to check if Amazon owes you money. Here’s how you can do that step by step:
1. Review your transaction reports
Go to Seller Central > Reports > Payments and check your transaction history. Look for discrepancies in refunds, reimbursements, or any unexpected deductions.
2. Check the Inventory Adjustments report
Navigate to Reports > Fulfillment > Inventory Adjustments to see if any of your inventory was lost or damaged in Amazon’s warehouse. If Amazon hasn’t reimbursed you, you may be eligible for a refund.
3. Analyze the Reimbursements report
Go to Reports > Fulfillment > Reimbursements to see all past refunds Amazon has issued. If you find missing reimbursements for lost, damaged, or returned items, you can file a claim.
4. Look at the Returns report
Head to Reports > Fulfillment > Customer Returns and verify whether customers returned the items. If a refund was issued but the product was never returned to inventory, you may be owed reimbursement.
5. Check for overcharged FBA fees
Sometimes, Amazon miscalculates FBA fees due to incorrect product dimensions or weight. Go to Reports > Fulfillment > Fee Preview and compare the recorded dimensions with the actual size and weight of your product. If you’re overcharged, you can request a correction and a refund.
6. Verify uncredited removals and disposals
If you requested inventory removals or disposals, check Reports > Fulfillment > Removal Order Detail to confirm whether Amazon processed them correctly. If Amazon charged you but never removed the inventory, you may be eligible for reimbursement.
7. Use automated tools for refund tracking
If manually checking each report feels overwhelming, Refunzo can track potential reimbursement claims automatically.
Once you identify discrepancies, the next step is to file claims with Amazon. Keep records of all reports, screenshots, and transaction details to strengthen your case.
Amazon’s refund policies and Claim deadlines
Amazon has specific policies for FBA refunds, and each type of claim has a deadline. If you don’t file within the given timeframe, you lose the chance to recover your money. Here’s a breakdown of key refund policies and Claim deadlines:
1. Lost or damaged inventory (by Amazon)

Claim deadline: 18 months from the date of the issue.

2. Customer returns not reimbursed

Claim deadline: 18 months from the original refund date.
How to check: Go to Reports > Fulfillment > Customer Returns and check whether the return was processed.
3. Overcharged FBA fees (Weight & Dimension errors)

Claim deadline: 90 days from the incorrect charge.
How to check: Compare the Fee Preview Report with your product’s actual size and weight.

Common mistakes that can get your claim rejected
Amazon is strict when it comes to refund claims, and even a small mistake can lead to rejection. To increase your chances of getting reimbursed, avoid these common errors:
1. Missing the claim deadline
Each type of reimbursement has a specific deadline (e.g., 9 months for missing inbound shipments, and 18 months for lost inventory). If you file a claim after the deadline, Amazon will reject it, no matter how valid it is.
Tip: Regularly audit your reports and set reminders to check for potential claims before they expire.
2. Not providing enough evidence
Amazon won’t approve a claim unless you submit clear proof. If you don’t include relevant reports, screenshots, or order details, your claim will likely be denied.
Tip: Always attach supporting documents such as shipment IDs, transaction records, and report screenshots when filing a claim.
3. Submitting duplicate claims
If you submit the same claim multiple times for the same issue, Amazon may flag it as an abuse of the system. This could lead to your case being ignored or, worse, your account getting warnings.
Tip: If your claim gets denied, review Amazon’s response carefully and submit a revised request with better proof instead of resubmitting the same claim.
4. Claiming for ineligible items
Not all items qualify for reimbursement. If your product was damaged due to improper packaging or handling before reaching Amazon, they won’t refund you. Similarly, if a customer damages an item during use, you aren’t eligible for reimbursement.
Tip: Understand Amazon’s FBA refund policies before filing a claim to ensure your case is valid.
5. Using incorrect claim categories
If you file a claim under the wrong category (e.g., reporting a missing inbound shipment under customer returns), Amazon may reject it outright.
Tip: Make sure you select the correct claim type in Seller Central > Contact Support > FBA Issue to avoid misclassification.
6. Not keeping track of your claims
Amazon handles thousands of seller claims daily, and some get lost in the system. If you don’t track your submitted claims, you might never receive a response or refund.
Tip: Maintain a spreadsheet of all claims, including submission dates, case IDs, and Amazon’s responses. If Amazon doesn’t respond within 7–10 days, follow up.
7. Overloading claims with unnecessary details
Submitting long, cluttered messages with unnecessary details can confuse Amazon’s support team, leading to delays or rejection.
Tip: Keep your claim short, clear, and to the point. Use bullet points to outline the issue and attach only the necessary documents.
