Hey everyone,

I’m dealing with a frustrating FBA inventory issue, and I’m wondering if anyone has faced something similar or has advice on how to escalate this.

I shipped 168 units of my product (one ASIN) in two boxes to the YYC4 warehouse. Both boxes were delivered and weighed 16 kg (35 lbs) each, which aligns with my shipment contents since each unit is 0.5 lbs. However, Amazon is claiming I only sent 38 units—which makes zero sense from a weight and shipping perspective. Why would I send two boxes for just 38 small units when I could have fit them all in one? Plus, I paid for shipping at 16 kg per box, which wouldn’t add up if I had only shipped a fraction of my inventory.

To make matters worse, my inventory ledger (screenshot below) showed 90 units available for sale at one point, proving that Amazon received and processed nearly 100 units. How is it possible for them to now say I was missing 100/138 units when their own system showed 90 units in stock at one point? If the shipment was short from the start, that number wouldn’t be there at all.

I disputed this, but Amazon denied my claim, stating there were “no discrepancies.” They also told me to open a “Missing From Inbound” case instead, which doesn’t make sense because the issue isn’t just about a transfer error—it’s that they acknowledged receiving 90 units and then somehow lost them.

Has anyone successfully fought a case like this? How can Amazon claim 100 units were missing from the beginning when their system clearly shows that a large portion of them were received? Very frustrated with Amazon. Any advice on how to escalate this would be appreciated.

Thanks in advance!
