Who it is for

Amazon FBA sellers, agencies, and inventory or finance agents comparing Reserved Inventory report snapshots to find material, persistent non-customer holds before a human investigates.

Delivery: usually a structured result, workbook, or ZIP depending on the tool.

How it stays safe

Friday performs snapshot arithmetic only on the dated Reserved Inventory rows, unit values, availability, and shipping rates you supply. It reads no Amazon account, report, shipment, transfer, or case. An unchanged non-customer reserved total does not prove the same physical units sat still, that units are stuck, or that Amazon made an error, and no release timing or availability is predicted. Friday does not publish listings and does not create, update, or submit a case, removal order, or any inventory change.
