Every place the money goes missing.
Amazon processes millions of events against your account. A fraction go wrong. At your volume, a fraction is a lot of money.
Fee overcharges
Dimension and weight errors that push a SKU into the wrong size tier. Referral fees charged at the wrong category rate. Oversize misclassification. These compound on every order until corrected — and unlike inventory claims, they refund at full dollar value.
Lost & damaged inventory
Units received into a fulfillment center that never sold, never returned, and never came back out. Inventory damaged in the warehouse or in transit between centers. Units marked disposed that you never asked to dispose of.
Since March 2025 these reimburse at manufacturing cost, which makes documentation of your actual per-unit cost essential. Without an invoice on file, Amazon uses its own lower estimate.
Return discrepancies
The customer was refunded but the unit never physically came back. The unit came back damaged but your account was still debited in full. The refund exceeded what the customer actually paid. A return was processed twice.
This is the highest-volume leak in most accounts, and the one that looks most normal on a statement.
Storage & surcharges
Monthly storage billed on incorrect cubic dimensions. Aged-inventory surcharges applied to units that had already sold or shipped out. Storage charged on inventory that was lost or disposed of. Removal fees for units that were never removed.
Inbound shipment shortages
You shipped 500, Amazon received 480, and the reconciliation quietly closed. Shipments marked complete with units still missing. Units received to the wrong SKU inside your own catalog.
Removals & disposals
Removal orders you paid for that never arrived back at your warehouse. Units disposed of instead of returned. Removal fees billed at the wrong weight tier.
Amazon does catch some of this automatically.
That is exactly what makes it dangerous. You see automatic credits land in your account and reasonably assume the system is working. It is working partially — and the partial coverage builds false confidence.
The automated system does not investigate whether your product was measured correctly. It does not notice that a return was refunded and never received. It does not appeal its own denials. And it does not care that your 60-day window is about to expire.
Recovering an overcharge is not the same as fixing it
Everything on this page is money you have already lost. The more valuable question is why the fee was wrong in the first place — and whether the packaging around your product is quietly parking it one tier above where it belongs.
