How to Avoid Duplicate FBA Claims

Jul 10, 2025

Submitting duplicate FBA claims can harm your Amazon seller account, delay reimbursements, and even lead to account suspension. Amazon strictly prohibits duplicate submissions, as they disrupt case resolution and waste resources. To avoid these issues:

  • Track claims carefully: Use a centralized system to log every claim, including shipment IDs, dates, and statuses.

  • Avoid resubmitting prematurely: Wait for Amazon's standard 5–7 business day response time before following up.

  • Coordinate with your team: Assign clear responsibilities and use shared logs to prevent overlapping submissions.

  • Leverage automation: Tools like Refunzo can monitor discrepancies, manage claims, and reduce human error.

What Are Duplicate FBA Claims

Definition of Duplicate FBA Claims

A duplicate FBA claim happens when you submit the same reimbursement request more than once for the exact same issue. This includes any submission that references the same Amazon Order ID for identical cases of lost inventory, damaged goods, or return discrepancies.

For instance, let’s say you file a claim for 10 missing units from shipment FBA15ABC123. If you submit another claim two weeks later for those same 10 units from that same shipment, Amazon will flag this as a duplicate.

Duplicate claims can also occur when you use multiple channels to file the same request. For example, submitting a case in Seller Central’s Case Log while also using Amazon’s automated reimbursement system will result in the system marking these as duplicates if they reference the same transaction details.

Now, let’s look at why these duplicate claims happen in the first place.

Why Duplicate Claims Happen

One of the main culprits behind duplicate claims is poor record-keeping. Without a centralized system to track filed claims, sellers often end up submitting the same request multiple times - sometimes weeks or even months apart. Managing a high volume of transactions without proper documentation only adds to the confusion.

For larger teams, miscommunication can also lead to duplicate claims. If team members aren’t coordinating, they might unknowingly file claims for the same issue, each assuming it hasn’t been addressed yet.

Another common reason is impatience. Amazon typically takes 5–7 business days to process claims, but some sellers resubmit too soon, thinking their original request has been overlooked. These premature submissions often end up being unnecessary duplicates.

Finally, the absence of a clear process for managing claims makes the problem worse. Without steps like reviewing the Reimbursements report by Amazon Order ID or checking the Seller Central Case Log, it’s easy to lose track and file duplicate requests.

Unfortunately, these mistakes can cause more harm than you might expect.

Problems Caused by Duplicate Claims

The most immediate issue with duplicate claims is rejection. Amazon’s system automatically flags and denies duplicate submissions, forcing you to start over. These rejections often come with vague responses, leaving you guessing about the exact reason for the denial.

Beyond just rejections, duplicate claims slow down the entire process. Amazon’s support team has to spend extra time sorting through and consolidating repeated cases, which can stretch the resolution timeline far beyond the usual 5–7 business days. This delay can directly impact your cash flow, especially if you’re waiting on significant reimbursements.

There’s also the risk of damaging your account health. Repeatedly filing duplicate claims can hurt your seller performance metrics and even jeopardize your eligibility for perks like the Buy Box. If Amazon flags your account for poor claim management, future reimbursement requests may face even more scrutiny, making it harder to recover lost revenue.

Lastly, duplicate claims can disrupt your overall reimbursement strategy. Sellers who struggle with managing these issues risk missing out on valuable opportunities to recover funds, which can add up to significant losses over time.

How to Prevent Duplicate FBA Claims

Avoiding duplicate claims is all about staying organized and keeping track of your processes effectively.

Keep Complete Records

Maintaining detailed records is a must. Track every shipment, fee dispute, and inventory issue with consistent and accurate data.

Your shipping records should include key details like Amazon's assigned shipment ID, shipment dates in MM/DD/YYYY format, and the number of units per SKU. Keeping this information consistent and readily available is crucial, especially when dealing with multiple shipments containing similar items.

For inventory tracking, document the condition of every item upon return, noting any differences between what the customer reported and the item's actual state. Log the processing status of each claim to identify any delays or bottlenecks. It’s also helpful to maintain a timeline with dates and status updates to back up your claims with clear evidence.

Regularly audit your records to meet Amazon's strict reimbursement deadlines. Weekly or monthly reviews of inventory reports and payment data can help you catch discrepancies early, rather than months later when it might be too late to act.

The goal is to make your documentation easy to access. Store everything in a well-organized system so your team can quickly verify whether a claim has already been filed. Centralizing these records will help ensure accuracy and streamline the process.

Use One System to Track All Claims

Centralizing your claim tracking is essential to avoid confusion and duplicate submissions. Whether you use a simple spreadsheet or specialized claim management software, having all your cases in one place gives you a clear view of what’s been filed and what’s still pending.

Your system should track the current stage of each claim in Amazon's workflow, provide a chronological record with dates and status updates, and document final outcomes. This real-time data flow keeps you informed about the progress of your claims and Amazon's actions.

Automation can be a game-changer here. It reduces errors, ensures consistency, and frees up your time to focus on growing your business instead of getting bogged down in administrative tasks.

A centralized and well-maintained tracking system is the backbone of an efficient claims process.

Create a Clear Process

Having a structured workflow is key to avoiding duplicate submissions. Without coordination, team members working on reimbursements may unknowingly file claims for the same issue.

Your process should include specific steps, such as:

  • Auditing inventory and fees regularly to spot discrepancies like lost items, damaged goods, or overcharges.

  • Checking Amazon’s FBA inventory reimbursement policy to ensure the issue qualifies for a claim.

  • Compiling necessary documents, including proof of inventory ownership, delivery confirmations, and invoices showing fee discrepancies.

  • Monitoring claim statuses in the "Case Log" section of your Amazon Seller Central account.

Amazon’s reimbursement policies can change frequently, which may affect eligibility and filing procedures. To stay ahead, assign someone on your team to monitor policy updates and adjust your processes as needed.

Finally, include a verification step before submitting any claim. Cross-check your tracking system and Amazon’s Reimbursements report to confirm the claim hasn’t already been filed. This quick double-check can save you from delays and rejections caused by duplicate submissions.

Using Automated Tools to Prevent Duplicate Claims

While manual tracking systems have their place, automated tools take accuracy and efficiency to the next level when it comes to preventing duplicate claims. In high-volume operations, human error is almost inevitable. Automated reconciliation tools provide a dependable way to avoid duplicate FBA claims while uncovering discrepancies that might otherwise slip through the cracks.

What Automated Reconciliation Tools Do

Automated reconciliation platforms work around the clock to monitor your FBA account, identifying opportunities for reimbursements. These tools dig into your inventory records, payment statements, and Amazon’s reports to uncover inconsistencies that could point to lost or damaged items, incorrect fees, or other issues.

For example, Refunzo’s lifetime free reconciliation service runs more than 20 automated checks on your FBA account. It examines everything from inventory adjustments and fee discrepancies to shipment errors and customer return issues. The platform flags problems and generates clear, actionable reports, making it easier to address them.

The system goes a step further by cross-referencing shipment records with inventory receipts, comparing fee charges against Amazon’s rate cards, and tracking inventory movements to identify unexplained losses. This thorough process ensures you catch every reimbursement opportunity while avoiding duplicate claims for the same issue.

Why Automation Helps

The numbers speak for themselves when comparing manual and automated processes. A 2023 Gartner survey revealed that 18% of accounting professionals make financial errors daily, with a third making mistakes weekly and 59% monthly. When managing FBA reimbursements across multiple products and marketplaces, these errors can add up quickly.

Automation minimizes the risk of typing errors and mismatches, ensuring consistent and accurate data processing. These tools use AI and rule-based systems to match data entries across platforms, detect inconsistencies, and predict likely matches based on historical patterns. Over time, they become even more precise, catching subtle discrepancies that manual checks might miss.

Businesses using automated finance tools report a 75% reduction in financial errors compared to manual methods. For Amazon sellers, this means fewer rejected claims, quicker reimbursements, and less time spent on administrative tasks.

Another major advantage is real-time monitoring. Automated systems flag discrepancies as they happen, rather than weeks or months later when you might miss Amazon’s reimbursement deadlines. On average, Amazon sellers lose 3-5% of their inventory value annually due to unnoticed discrepancies, making early detection essential for protecting profits.

These automated tools not only save time and reduce errors but also open the door to additional services that simplify the reimbursement process even further.

Step-by-Step Guide to Submit Accurate FBA Claims

Submitting an accurate FBA claim right from the start can save you the hassle of dealing with duplicate submissions or rejected cases. A clear and organized approach ensures Amazon has everything it needs to process your reimbursement without unnecessary delays.

Step 1: Gather All Necessary Documents

Before opening a case, make sure you have all the supporting documents required to back up your claim. Missing paperwork is one of the main reasons for delays or denials.

Here’s what you’ll need, depending on the type of claim:

  • Inventory discrepancies: Original invoices (proof of purchase), packing slips (what you shipped), and delivery confirmations from your carrier.

  • Damaged products: Clear photos showing the condition of the items when they arrived at the fulfillment center.

  • Fee-related claims: Identify the incorrect charge, provide a detailed explanation of the discrepancy, and include fee breakdowns and invoices. Compare Amazon's fees with their official rate cards to highlight the error. Note: Amazon updated its requirements for these claims in August 2024.

  • Removal order issues: Removal order confirmations, tracking numbers, and proof that the items were not received (if applicable).

  • Lost shipments: Shipping receipts, carrier tracking details showing delivery to Amazon, shipment creation records from Seller Central, and photos of the packaged items before shipping.

Keep digital copies of all documents organized by date and claim type. Once everything is ready, double-check to ensure no claim has already been filed for the same issue.

Step 2: Confirm No Existing Claim

Before you proceed, verify that you haven’t already submitted a claim for the same issue. Amazon automatically rejects duplicates, and repeated submissions can even impact your account health negatively.

  • Reimbursements report: Go to Seller Central and navigate to Reports > Fulfillment > Reimbursements. Filter by FNSKU to check if a reimbursement for the issue has already been processed.

  • Shipment discrepancies: Review your shipping queue in Seller Central. Click the shipment ID and check the "Contents" tab for any noted discrepancies. Amazon may have already issued a reimbursement automatically.

  • Returns and removal orders: Check reports like Orders > Manage Returns > FBA Returns to see if a reimbursement was issued for a returned item. For removal-related claims, review the Removal Order Detail and Removal Shipment Detail reports.

You’re allowed only one claim per shipment. If you need to add information to an existing claim, update the original case instead of filing a new one. Use Seller Central’s search feature to locate related cases by entering keywords relevant to your issue.

Step 3: Submit and Track Your Claim

Once you’ve confirmed there’s no duplicate claim, submit your case with all the required documents in one go. A clear explanation and complete documentation can help avoid delays caused by follow-up requests.

After submission, monitor your claim’s progress through the case management dashboard. Amazon provides status updates to keep you informed:

Status

Description

Action

Open

Case is under review

Wait for Amazon's response

Pending

More information is required

Provide the requested details

Resolved

Case is closed

Verify the reimbursement amount

Escalated

Supervisor review is needed

Watch for updates

Denied

Claim was not approved

Review the reason and appeal if needed

Check the Reimbursements report weekly to track your claim. Filtering by FNSKU can sometimes provide faster updates than waiting for email notifications.

Keep a record of each claim’s ID, date, products, and amount to stay organized. This will help you avoid duplicate submissions in the future while also giving you a clear overview of your reimbursement history.

If Amazon requests additional information, respond promptly with exactly what they ask for. Delays can result in the case being automatically closed, forcing you to start over. For claims that remain open beyond 10 business days, consider setting a reminder to follow up. While Amazon typically responds within 5–7 business days, some cases may take longer, and a polite follow-up can help move things along.

Common Situations That Create Duplicate Claims

Understanding the typical scenarios that lead to duplicate FBA claims can save you from unnecessary headaches and expenses. These issues often arise from miscommunication, overlapping duties, or the lack of a centralized system to keep track of claims.

Multiple Team Members Handle the Same Case

One of the most common causes of duplicate claims is when multiple team members unknowingly work on the same case. For instance, one person might submit a claim for an inventory discrepancy, while another files a similar claim independently. Without a shared tracking system, these duplicate submissions often go unnoticed until flagged.

The solution? Clear ownership and a shared log. Assign specific team members to handle particular types of claims and maintain a central log that includes product IDs, discovery dates, and claim numbers. This way, everyone can see what’s already been submitted. A shared tracking system allows team members to access claim statuses and avoid overlapping efforts. Before filing any claim, always check both the shared log and Seller Central’s case history to ensure there’s no duplication.

Timing also plays a big role here - overlapping responsibilities and poor coordination can quickly lead to duplicate claims.

Resubmitting Claims When Amazon Takes Too Long

It’s frustrating when Amazon takes longer than expected to process a claim, but submitting a new case too soon can create duplicates and complicate the reimbursement process.

Patience and proper tracking are essential. Instead of rushing to resubmit, monitor the status of your claim in Seller Central. Use the case ID to follow up politely on unresolved cases, and check for status updates to see if Amazon needs more information or if the case is still under review. Setting reminders to regularly check on pending claims can help you stay organized and avoid unnecessary duplicate submissions.

How you manage claims across different stages in the process can also lead to duplication.

Overlapping Claims for Shipments and Returns

Another common issue arises when sellers file separate claims for different stages of inventory movement - like shipments, storage, customer returns, or removal orders - without realizing they’re related. For example, missing units from a shipment might later show up in customer returns or removal orders, leading to multiple claims for the same discrepancy.

The fix? Consolidate related issues into one claim. Review all relevant reports - shipments, returns, and removals - before filing a claim. If you uncover additional discrepancies after submitting a claim, update the existing case instead of starting a new one. This approach provides Amazon with a complete overview of the issue, making the process smoother and reducing the chances of duplicate claims.

Key Points for Avoiding Duplicate FBA Claims

To sidestep duplicate FBA claims, focus on four main strategies: staying organized, setting up clear workflows, training your team, and leveraging automation.

Start with strong organization. Maintain detailed records for every claim you file. Before submitting, cross-check your Reimbursement Reports to ensure you're not filing for the same issue twice. This simple habit can save you from unnecessary complications.

Establish clear workflows. Create a step-by-step process for handling FBA claims and assign specific tasks to team members. Centralizing claim tracking helps eliminate overlapping efforts and keeps everyone on the same page.

Train your team to reduce mistakes. Make sure your team is well-versed in Amazon's reimbursement rules and procedures. Regular training sessions not only cut down on errors but also improve accountability across the board.

Use automation for better accuracy. Tools like Refunzo streamline reconciliation by analyzing multiple criteria, identifying eligible reimbursements, and managing claims. Automation reduces the chances of human error and ensures no opportunities are missed.
