Monitor inventory and replenishment signals

Inventory helps you monitor stock levels, fulfillment identifiers, and replenishment-related fields. It is designed to make stock risk easier to identify without switching between reports.

Inventory page with SKU, ASIN, FNSKU, and stock fields — Inventory keeps SKU, ASIN, FNSKU, and stock-related fields in one table.

Key identifiers

SKU identifies the seller SKU.
ASIN identifies the Amazon product.
FNSKU identifies FBA inventory units when available.

Long values

When SKU, ASIN, FNSKU, or title values are too long to fit, hover the truncated text to see the full value. Use copy buttons for identifiers when needed.

Inventory checks

Use Inventory to review available inventory, inbound inventory, reserved inventory, and age-related signals where available. If inventory looks stale, confirm SP-API authorization and recent sync status for the store.
