If you sell on Amazon using FBA (Fulfilled by Amazon), you know how convenient it is to let Amazon handle storage, shipping, and customer service. But with all those services comes a long list of fees — and sometimes, those fees aren’t charged correctly.
Yes, fee errors happen more often than many sellers realize. And if you don’t catch them, you could be losing money without even knowing it.
Let’s break down some of the most common Amazon FBA fee errors and how you can spot and fix them to claim your Amazon FBA reimbursements.
Error 1: Weight and dimension mistakes
Amazon charges fulfillment fees based on the weight and size of your products. But sometimes, the system records the wrong measurements. For example, if Amazon’s system mistakenly thinks your small item is oversized, you’ll get hit with much higher storage and shipping fees.
Regularly check the size and weight details of your listed products. If you notice a mismatch, file a correction request to avoid overpaying.
Error 2: Overcharged storage fees
Storage fees depend on how much space your products take up in Amazon’s warehouse. But just like with weight, incorrect dimension records can lead to inflated storage costs.
It’s a good idea to review your monthly storage fee reports. Compare the fees charged to the actual size of your products and make sure they match.
Error 3: Long-term storage fee mistakes
Amazon applies long-term storage fees for inventory sitting in the warehouse too long. But sometimes, these fees are charged even if you recently removed or sold the items.
Check your long-term storage reports carefully. If you see fees on products you know were sold or cleared, file a dispute.
Error 4: Removal and disposal fee errors
If you ask Amazon to remove or dispose of inventory, they charge a removal fee. Sometimes, sellers notice being charged removal fees without actually requesting removals — or being charged twice for the same batch.
Keep an eye on your removal order history and make sure all charges match your requests.
Error 5: Refund-related fee mistakes
When a customer returns an item, Amazon often refunds the buyer but doesn’t always refund you the seller’s fees. This means you might lose both the product and the fees you originally paid.
According to the Amazon FBA reimbursement policy, sellers are entitled to get back certain fees when returns happen, especially if the item was returned damaged or not at all. Review your return and refund reports to catch these missed reimbursements.
How to stay on top of fee errors
- Regularly download and review your FBA reports.
- Keep track of product size and weight details.
- Monitor your removal, disposal, and return records.
- Use automated tools or services (like Refunzo) to catch errors you might miss manually.
- File claims quickly, as Amazon has time limits on when you can request reimbursements.
Final thoughts
Common Amazon FBA fee errors can quietly drain your profits if you’re not paying attention. But by staying informed, reviewing your reports, and following the Amazon FBA reimbursement policy, you can recover lost money and keep your business running strong.
Remember — every small refund adds up over time. So take charge, track your fees, and make sure you’re only paying what you truly owe.
