FBA inventory is a set of states, not one stock total
Restocking depends on usable units and when replacement units become available. Cost control also needs storage exposure, stock age, and the events behind possible reimbursement claims. A single inventory total cannot answer all of those questions.
These guides connect stock-state diagnosis, replenishment, inventory-health checks, and reimbursement evidence. They cover selected FBA operating decisions rather than every fulfillment fee or inbound-shipping procedure.
Does Reserved mean the inventory is lost?
No. Reserved inventory can relate to customer orders, fulfillment-center transfers, or processing. Seller Central and API reports categorize the holds differently, so label the source of each figure before reconciling totals. The reserved-inventory guide explains which holds need attention and why a possible recall needs confirmation from the notice rather than an assumption based on the quantity.
A reserved unit, an inbound unit, and a sellable unit are not interchangeable supply. Keep those states separate when estimating coverage.
What makes a restock decision actionable?
Compare usable stock coverage with a dated replenishment arrival. An inbound total without an expected availability date can conceal a gap. Prefer the forecast-based coverage measure when available; label a trailing-sales estimate so its assumptions are visible. The FBA restock guide connects the expected runout date to the location and timing of replacement stock.
| Question | Evidence to inspect | Guide |
|---|---|---|
| Will usable stock last until replenishment? | Coverage estimate and dated inbound supply | Restock planning |
| Why are units unavailable? | Reserved categories and any relevant notice | Reserved inventory |
| Which stock creates cost exposure? | Capacity, storage, age, and low-inventory signals | Inventory health |
| Is a loss or return worth a claim review? | Event type, eligibility, deadline, and existing reimbursement | Reimbursement audit |
A reimbursement candidate is not an approved claim
Different loss and return events have different eligibility and filing rules. Match the event to its policy before valuing it; do not value every unit at its retail price. The reimbursement guide also marks a firm execution boundary: the Selling Partner API does not file the claim. The agent assembles the evidence and tracks the queue; a person files in Seller Central.
The Selling Partner MCP supplies the account records for these reviews. If units lack an active offer, use listing suppression and stranded-inventory diagnosis to establish whether the next action is a listing repair rather than another replenishment order.
