Selling on Amazon is a powerful way to grow your e-commerce business, offering global reach, streamlined logistics, and access to millions of customers. However, behind the scenes, many sellers face a common but often overlooked challenge: overcharges and hidden fees that can slowly eat into profits. From incorrect FBA (Fulfilled by Amazon) fees to unexplained storage costs and shipping errors, these charges can add up quickly—especially for sellers who aren’t tracking them closely.

That’s where Aidevisor.com steps in. Aidevisor is a full-service Amazon business support company, offering everything from store setup to brand management. But one of its most valuable services—often underestimated—is fee auditing and reimbursement recovery. This article dives deep into how Aidevisor helps sellers not only avoid unnecessary costs but also recover lost money and protect their margins.

Understanding Amazon’s Fee Structure

Before exploring how Aidevisor can help, it’s important to understand the complex nature of Amazon’s fees. There are multiple layers of charges Amazon sellers face, including:

1. FBA Fees

These include:

• Fulfillment fees (picking, packing, shipping)
  
  
• Storage fees (monthly and long-term)
  
  
• Removal and disposal fees
  
  

2. Referral Fees

Amazon charges a percentage of the product price—ranging from 6% to 45%, depending on the category.

3. Refund Administration Fees

When a customer returns an item, Amazon keeps a portion of the referral fee.

4. Labeling & Prep Fees

If your inventory doesn’t meet Amazon’s FBA prep standards, they’ll charge per unit for labeling, bagging, etc.

5. Weight & Dimensional Errors

Incorrect product measurements can cause higher shipping and storage fees.

6. Inventory Lost or Damaged in Amazon Warehouses

Amazon is supposed to reimburse sellers when items are lost or damaged due to their error, but these claims are often missed or denied.

For new and even experienced sellers, keeping track of these charges—and distinguishing which ones are legitimate—can be overwhelming.

Common Overcharges Sellers Face

Let’s look at some of the most frequent overcharging issues Amazon sellers face:

✦ FBA Weight & Dimension Errors

Amazon sometimes mismeasures your product dimensions, resulting in inflated fulfillment and storage fees. A few centimeters can lead to significant cost increases, especially with high-volume sales.

✦ Lost or Damaged Inventory

When Amazon loses or damages inventory in their warehouse, sellers are entitled to reimbursement. However, these claims aren’t automatic and require careful documentation and filing.

✦ Unclaimed Refunds

Sellers might miss out on reimbursements due to returned items that were never restocked or incorrect refund processing.

✦ Duplicate Fees

In some cases, sellers are charged twice for shipping or return handling. Without routine checks, these small errors can go unnoticed for months.

✦ Long-Term Storage Fees

If inventory isn’t selling quickly, sellers may be charged long-term storage fees—even when the data is incorrect.
