SELLERLOGIC Lost & Found Full-Service: Automated Identification and Reimbursement of FBA Errors

A lot of money is lost due to unclaimed FBA errors.

Without an intelligent software solution, detecting FBA errors requires significant time and effort. At the same time, completely neglecting FBA error detection is also not an option for your business, since this increases the likelihood of substantial financial loss from unclaimed reimbursements. Many FBA sellers lack the expertise and time to manually review every detail, consolidate reports, and identify errors. Consequently, medium-sized enterprises using FBA risk losing 3 % of their annually generated turnover generated from FBA sales.

SELLERLOGIC handles the recovery of your funds in its entirety, allowing you to focus on more critical tasks. Take the enforcement of your refund claims against Amazon to the next level with SELLERLOGIC Lost & Found Full-Service.

Frequently Asked Questions
Other Topics:
Dealing with cases
Contract information
How do you get the FBA data/interface?

We use the Amazon Marketplace Web Service API interface and extract the data from the system that is relevant to our research.

Since the reimbursement is processed grossly. Is the fee of 25 % calculated on the gross or net amount of the reimbursement in the invoice?

The commission is calculated based on the total amount refunded by Amazon.

When do you charge the 25 %?

The fee will be invoiced at the beginning of the following month.

What Information is required from you, and how will this information be used?

In Germany and Austria, billing is conducted via direct debit. For this, the IBAN must include the respective country code “DE” or “AT”. SEPA direct debit mandates from outside Germany and Austria cannot be processed.

In all other countries, you can only pay by credit card. To process your payments, SELLERLOGIC’s payment service provider requires your credit card details. This includes your CVV2 or CVC2 number, which is a three- or four-digit combination printed on your credit card. Transmitting all credit card data to the payment service provider is for cardholder authentication and is a secure and standardized international process.

The processing of credit card data is carried out exclusively – and within full PCI compliance – by SELLERLOGIC’s payment service provider. At no time does SELLERLOGIC have access to or store its customers’ credit card data. If you have further questions on this matter, our Customer Support is happy to help.

In closed cases and in “actual reimbursement“, is the Lost & Found fee already deducted?

No, the SELLERLOGIC fees are shown in a separate section at the transaction level.

When do you charge the 25 % fee?

The fee will be invoiced at the beginning of the following month.

What are the consequences of not using Lost & Found or ignoring the problems?

Amazon imposes different deadlines for various types of errors, some up to 18 months. Every passing day can result in reimbursement claims for FBA errors expiring, causing you to miss out on the money rightfully owed to you.

Dealing with cases
Do I need to actively participate in the reimbursement process as a user?

No, typically, SELLERLOGIC handles the entire reimbursement process for you – from error analysis to the crediting of funds to your Amazon account. In rare cases, documents may be required from you, such as invoices from your supplier or proof of delivery. If this is the case, you will receive a notification from SELLERLOGIC via email.

Does SELLERLOGIC close the cases automatically by using the information from Seller Central?

Cases are closed based on completed reimbursements. This ensures that SELLERLOGIC verifies that the promised refund from Amazon has indeed been received.

What do I do if Amazon does not agree to a reimbursement?

Our FBA experts will communicate with Amazon from the moment the case is found, enforcing your claim. No communication with Amazon is required from your end.

Could there be an issue if I (additionally) check incoming shipments (to Amazon) manually via the delivery schedule (shipping menu) and apply for reimbursements myself?

If the case was opened at Amazon for delivery before the case was published by Lost & Found, the case will be closed free of charge. Contact SELLERLOGIC Support for this

Why do the estimated and actual reimbursements sometimes differ?

The calculation basis is an average selling price over a certain period, which may not always be fully available to the system. The estimated amount serves only as a guideline for a potential refund amount. The exact refund amount will be displayed to you in the SELLERLOGIC refund overview.

What about products that are damaged on their way to the customer and for which Amazon simply sends a “new” product?

SELLERLOGIC also detects these errors. Refunds can be claimed from Amazon for up to 18 months for this case type.

In my case, no estimated refund is displayed. What could be the reason for this?

If no estimated refund is displayed for your cases, it may be because the necessary data is not available to the system.

Does Lost & Found also identify missing returns or only items lost in the Amazon warehouse?

SELLERLOGIC also identifies orders that were not returned and have already been refunded by Amazon.

Contract informationen
Are the services provided by SELLERLOGIC compliant with GDPR?

Yes. A corresponding contract is provided for all services by SELLERLOGIC.

Is it also possible to book only the Lost & Found module, or do I have to book it together with the Repricer?

You can book each module separately.

How long is the notice period?

SELLERLOGIC can be canceled daily. No notice period is required. However, after deactivation, all open cases must be processed within the set period.
