Overview

Amazon's Restock Inventory report is one of the most important planning tools available to FBA sellers. It provides data-driven recommendations on which products need replenishment, how many units to send in, and when shipments should arrive at fulfillment centers. For sellers managing dozens or hundreds of SKUs, this report is essential for maintaining healthy stock levels without tying up excessive capital in overstock.

Key Points / What Sellers Need to Know

• Replenishment recommendations are automated — Amazon calculates suggested restock quantities and ship-by dates based on your current inventory levels, sales velocity, and projected demand.
• Customization improves accuracy — You can configure lead times, case pack quantities, and other supplier details so that Amazon's suggestions better reflect your actual supply chain.
• Days of supply drives urgency — The report estimates how many days your current stock will last, and flags items that are running low or already out of stock.
• Inventory level thresholds may apply — For products subject to restock limits, the report publishes minimum, maximum, and threshold values for both the current and following month.
• Multiple inventory states are tracked — The report breaks down your stock across available, inbound, reserved, transfer, processing, and unfulfillable categories so you can see exactly where every unit sits.

Understanding the Report Columns

The Restock Inventory report contains a detailed breakdown of every FBA SKU in your catalog. Each row includes product identifiers such as ASIN, FNSKU, and your merchant SKU (MSKU), along with the product title, condition, and supplier part number. Financial data includes the currency code and listed price for each item. Sales performance is captured through two metrics covering the last 30 days: total revenue and total units sold. These figures feed directly into Amazon's demand projections.

On the inventory side, the report distinguishes between several stock states. "Total inventory" combines all available, inbound-shipped, and reserved units including those in fulfillment center transfer. "Available inventory" reflects units that are ready to be picked, packed, and shipped immediately. "Inbound inventory" covers units in shipments you have created, provided tracking for, or that have arrived and are being processed. "FC transfer" and "FC processing" track units moving between fulfillment centers or undergoing additional handling. "Reserved" units are already allocated to customer orders, and "unfulfillable" units are physically present but not in sellable condition.
