Amazon owes you money.
We get it back — automatically.

Amazon regularly loses, damages, and miscounts your FBA inventory — and rarely volunteers a refund. SellerToolKit's Chrome extension finds every discrepancy and files the claims for you. Automatically.

Amazon loses more inventory than you think.

Every inbound shipment is an opportunity for units to go missing, get damaged, or be miscounted. Amazon doesn't always flag it — and most sellers never notice.

📦

Lost inbound units

You ship 500 units. Amazon receives 487. The 13 missing units have a value — and you're owed a reimbursement.

⚠️

Damaged stock

Items damaged in Amazon's fulfilment centres are eligible for reimbursement. Without a system, these claims go unfiled.

🔄

Returns not restocked

Customer returns that are never returned to your inventory are a common FBA error — and another source of unclaimed money.

How it works

SellerToolKit handles the entire reimbursement process from start to finish — with no manual work from you.

1

Find

SellerToolKit automatically scans every inbound shipment, return, and inventory movement across all your marketplaces — identifying every discrepancy that qualifies for a reimbursement.

2

File

Claims are automatically submitted to Amazon on your behalf. No spreadsheets, no copying case numbers, no manual submissions. SellerToolKit does it all.

3

Recover

Approved reimbursements are tracked in SellerToolKit alongside your full P&L — so you can see exactly how much you've recovered and how it affects your real profit.

Everything your current setup is missing.

Most sellers either do reimbursements manually or not at all. Here's how SellerToolKit compares.
