Amazon Accounting III: How to Calculate the Reimbursement?


When you are a FBA seller, Amazon is responsible of handling your stock and ship what your customers buy from you. FBA program is very convenient when you are a seller, and it is usually recommended if you are a third-party seller so that you are not required to handle your stock and take care of the shipment process.

However, Amazon needs to deal with a flood of items in its fulfilment centers, incidents can happen, and you can end up with damaged items, destroyed stock, overcharged fees etc. Of course, if this kind of mistakes happen Amazon should reimburse you.

Reimbursement occurs when Amazon causes the loss of your products or overcharging you fees in the fulfilment process.

First, we would like to explain to you in details how reimbursement works and how to calculate it. Then we will explain to you how to discover the missing reimbursements and what are the solution to make sure Amazon doesn’t owe you more money.

Reimbursement Criteria

As we mentioned previously the reimbursement occurs in special situations:

  1. The item has been damaged during handling and/or while the delivery occurred (warehouse, transportation)


  1. The item(s) has been lost


  1. Your stock has been accidently destroyed


  1. You have been overcharged by Amazon

You need a valid reason for Amazon to reimburse you or to replace the damaged item(s), however if the item(s) have been lost and Amazon had already reimbursed you before the item has been found, in this case, Amazon can request to give the money back. (Reverse reimbursement)

There are also times when Amazon may just let you keep the money because they can sell the returned, warehouse damaged, used, or refurbished products under the Amazon Warehouse deal. Usually, these items are heavily discounted and consist of open-box items like TVs, laptops, tablets, home audio, kitchen & dining, home goods, outdoors, and more.

We suggest you keep an eye on your inventory, if you notice irregularities from your side, you can file a claim with a specific form. You have 18 months to contest any reimbursement decision.

Finally, keep in mind that each situation is unique, and Amazon treats all requests case-by-case.

For more information, we invite you to read Amazon reimbursement policy.

Check the Inventory Adjustments Section

If you want to handle reimbursement audit by yourself, you can check the adjustments section on your seller central account.

We suggest you check this section to have a better overview concerning your items status. The Inventory Adjustments shows the history of adjustments to your inventory in response to issues such as disposition changes, misplaced inventory, found inventory, and ownership corrections.

Audit Experts

Last solution, you can look for a service provider specialized in conducting audit of account reimbursement to help you to track and recover the money that Amazon potentially owes you.

We recommend you pay attention to the reimbursement on your Seller Central because you will never know if Amazon owes you a large sum of money from the damaged or lost items or other reasons that may cause in your loss of profit due to Amazon’s mishap since Amazon handles billions of items in their fulfilment centers and it might be possible that some mistakes haven’t been rectified or acknowledged.
