Inventory & Replenishment
Understand Amazon inventory and replenishment data, including stock health, FBA planning, ledger movements, and Subscribe & Save risk.
Inventory and replenishment data helps you understand what stock is available, how stock moved, which products may run out, and where recurring demand creates future risk. Use this guide when the question is operational first, then move into the technical pages when you need tables or SQL.
What this area covers
DataHawk brings together several Amazon inventory views, each with a different job.
| Area | What it helps with |
|---|---|
| Current stock | See available, inbound, reserved, or unavailable inventory |
| Historical inventory | Track how stock levels changed over time |
| Inventory ledger | Investigate movements such as shipments, returns, adjustments, and removals |
| FBA planning | Review restock, aged-stock, and removal recommendations |
| Subscribe & Save | Plan for recurring subscription demand and missed deliveries |
The right view depends on whether you need a snapshot, a historical trend, or a movement-level explanation.
Common use cases
Use inventory and replenishment data when you want to:
- Detect stockout risk before it affects sales
- Explain why inventory dropped for a product
- Compare available stock with recent demand
- Prioritize aged inventory that may create storage fees
- Plan for upcoming Subscribe & Save demand
- Reconcile operational questions across dashboards and raw tables
FBA, FBM, and Subscribe & Save
For FBA products, Amazon inventory reports provide fulfillment-network stock, planning, and ledger views. For FBM or MFN products, availability often comes from listing-level data instead of FBA stock reports. Subscribe & Save adds another layer because recurring demand can be missed if stock is unavailable.
Subscribe & Save stockouts can be more damaging than a single missed sale because missed deliveries may weaken recurring customer demand.
How to investigate an inventory issue
Start with the current stock view
Check whether the product has available, inbound, reserved, or unavailable units today.
Review recent movement
If stock changed unexpectedly, use inventory movement or ledger detail to see shipments, returns, removals, adjustments, and warehouse activity.
Compare against demand
Look at sales, estimated sales, advertising, and Subscribe & Save forecast signals to understand whether demand is rising faster than replenishment.
Decide the next action
Use restock, removal, and aged-stock signals to decide whether to replenish, transfer, discount, or remove inventory.
