Amazon's Inventory Ledger Report: Your Single Source for FBA Inventory Data
Amazon consolidated multiple legacy FBA inventory reports into the Inventory Ledger report as of March 31, 2023. Sellers need to use this single report for all inventory movement tracking, reconciliation, and accounting within Amazon's fulfillment network.
Overview
Amazon has consolidated multiple legacy FBA inventory reports into a single, unified tool called the Inventory Ledger report. This change, which took effect on March 31, 2023, means sellers now have one centralized report for tracking all inventory movements, adjustments, and balances within Amazon's fulfillment network. Understanding how to use the Inventory Ledger report is essential for any FBA seller who relies on inventory data for accounting, reconciliation, or operational planning.
Key Points / What Sellers Need to Know
- Single replacement for multiple reports - The Inventory Ledger report replaces over a dozen legacy FBA reports, including the Daily Inventory History, Monthly Inventory History, Inventory Adjustments, Inventory Reconciliation, and Received Inventory reports, among others.
- No disruption if you transition now - Amazon discontinued the old reports on March 31, 2023, so sellers who haven't yet switched should begin using the Inventory Ledger immediately to ensure continuity.
- Multiple access methods - The report can be viewed online in Seller Central, downloaded as a file, or accessed programmatically via API, giving sellers flexibility in how they integrate the data into their workflows.
- Comprehensive filtering options - Sellers can filter by date range, event type (such as receipts, shipments, adjustments, or disposals), ASIN, FNSKU, and fulfillment center to narrow down the exact data they need.
- API users should review developer documentation - For sellers pulling reports through the Selling Partner API, Amazon provides specific developer documentation on setting request filters for the Inventory Ledger.
What the Inventory Ledger Report Covers
The Inventory Ledger report provides a detailed, event-level view of every inventory movement within Amazon's fulfillment centers. This includes units received from inbound shipments, customer orders and returns, removals and disposals, adjustments made by Amazon (such as damaged or lost inventory corrections), and transfers between fulfillment centers. Each event is timestamped and categorized, making it straightforward to trace the lifecycle of any unit from the moment it arrives at an Amazon warehouse to when it leaves. The report also includes beginning and ending balances, which are critical for inventory reconciliation and financial reporting.
