SellerLogic Lost & Found: Automated identification of FBA errors

A lot of money is lost due to unreclaimed FBA errors

Without intelligent automation, FBA errors are difficult to identify or can only be identified with great effort. You will lose a lot of money if you do not claim the reimbursements to which you are entitled. As a rule, you lack the know-how and the necessary time to manually analyze every small detail, merge the necessary reports and interpret errors. As a result, medium-sized dealers who use FBA can lose several thousand euros a year. SellerLogic makes the FBA errors visible and supports you in preparing the data, documentation of the cases and the communication with Amazon. Use this unique tool now: SellerLogic Lost & Found.

FBA-Fehler können passieren, dürfen aber nicht unentdeckt bleiben.

Nobody "packs " perfect. FBA errors happen. SellerLogic Lost & Found makes them visible.

The employees in Amazon shipping centers are involved in many complex logistics processes, and they are under enormous time and effectiveness pressure.

ERP systems, booking systems, payment systems and transport systems carry out work steps during, before and after the process; customers receive articles and return articles. Errors cannot be avoided in such complex processes.

FBA errors can happen, but they must not be left undiscovered.

Lost & Found shows all undiscovered reimbursement claims

Each conspicuous transaction is created in Lost & Found as a separate transaction. Four different case states - New Cases, In Progress (Response from Amazon pending), In Review (Response from SellerLogic pending), Closed - show the current status of your findings. Various filter options make it easy to find the data you are looking for.

Identify your claims and enforce them cost-effectively

Lost & Found allows you to discover a new calculation of profitability. In just one click, SellerLogic offers you a solution for individual reimbursement claims for which previously it was not worth investing time and effort.

While you are working on your daily tasks, complex analyses and calculations are performed on the tool. Receive accurate information that allows you to open your claims cases. With a reasonable cost-benefit ratio, you can assert your claims.

Only a professional solution can detect the FBA problems

A successful analysis of individual transactions requires the consolidation of multiple FBA reports, which may have to cover long periods of time. A manual or Excel-supported data processing is not economically feasible due to the complexity of various problem sources and the enormous amount of time required.
