You can download reports in comma separated values (.csv) or text (.txt) format. Using .csv format will let you open reports in a spreadsheet, however, the leading zeros from MSKUs, ASINs, and FNSKUs will be dropped. If you require the leading zeros, you can download the file in .txt format. For more information on how to import a .txt file, review the help content for the spreadsheet application you are using.
Making a decision on replenishing inventory requires three primary data points: sales velocity (average weekly sales), on-hand inventory (fulfillable quantity), and inbound quantity. These three data points are used to calculate your inventory coverage before you run out, commonly known as weeks of cover (WOC) and calculated as on-hand inventory plus inbound quantity divided by average weekly sales.
To fully reconcile inventory balances, it helps to understand the various inventory events that contribute to your ending balance. There is a report for each inventory event to help you identify the key details. We recommend reviewing inventory events in this order:
Starting inventory balance + received inventory - customer orders + customer returns +/- adjustments - removals = ending inventory balance
Use the Monthly Inventory History report to determine the prior month’s ending inventory balance for an SKU or set of SKUs.
Use the Received Inventory report to identify inventory receipt credits to add to your starting inventory balance.
Customer orders generally lead to shipments reducing your overall inventory balance. Use the Customer Shipment Sales report to identify the shipped quantity of an SKU or set of SKUs in a given time period.
Customer returns can add items back into your inventory pool. Use the FBA Customer Returns report to learn how many units of a SKU or set of SKUs have been returned and credited to your inventory balance in a given time period.
Occasionally, adjustments are made to your inventory balance because of unexpected fulfillment center or customer issues. Use the Inventory Adjustments report to track those adjustments.
Sometimes adjustments lead to a reimbursement. Use the Reimbursements report to see the items for which you have been reimbursed.
Submitting an order to remove inventory from the fulfillment center will reduce your inventory balance. To see details about the quantity that was removed, use the Removal Shipment Detail report.
