What Sellers Use This For

Aged inventory surcharge forecasting. The quantity-to-be-charged-ais-* and estimated-ais-* fields by day bracket show exactly which SKUs are approaching or already in surcharge territory and what the projected cost is. Acting on this data before the charge date is how you avoid paying it.

Restock planning. Recommended ship-in quantity, Recommended ship-in date, and days-of-supply give you Amazon's own restocking signals per SKU. Pull these into a sheet to build a reorder calendar without manually checking each product.

Sell-through monitoring. sell-through, weeks-of-cover-t30, and weeks-of-cover-t90 show how quickly each SKU is moving relative to available stock. A low sell-through with high aged inventory is the signal to run a promotion or plan a removal before surcharges accumulate.

Storage cost projection. estimated-storage-cost-next-month gives you the forward-looking storage fee per SKU so you can factor it into margin calculations before the bill arrives.
