What This Report Covers

✅ Inventory History stores daily FBA inventory snapshots per SKU, giving you a time-series view of how your stock levels have changed over any period.

‍

✅ Every inventory state is captured per snapshot: fulfillable, reserved, inbound stages, unsellable, researching, and future supply quantities.

‍

✅ Replenishment quantity from Amazon's restock recommendations is stored alongside each snapshot so you can track restocking signals over time.

Inventory History is a Gorilla ROI dataset that stores daily FBA inventory snapshots for each SKU. Amazon's own inventory reports only return the current state. Gorilla ROI captures and stores each snapshot so you have a historical record to query, trend, and analyze over time.

What Sellers Use This For

Stock level trending over time. afn-fulfillable-quantity by Date lets you chart how available stock has moved for any SKU over weeks or months. This is the data behind stockout pattern analysis and seasonal inventory planning.

Stockout event identification. Scanning afn-fulfillable-quantity across dates shows exactly when a SKU hit zero and for how many days. Use this to calculate the revenue impact of stockouts and build lead time benchmarks.

Inbound pipeline history. afn-inbound-working-quantity, afn-inbound-shipped-quantity, and afn-inbound-receiving-quantity over time show how long your shipments typically take at each stage. Identifying bottlenecks in the receiving process starts here.

Replenishment quantity tracking. ReplenishmentQuantity stored alongside each snapshot lets you see how Amazon's restock recommendation has changed over time for each SKU, giving you context for restocking decisions.
