# inventoryItem

query · in the family [Inventory item](/reference/inventory-item/)

## What it does

Look up one record — an inventory item — one variant’s stock identity.

A InventoryItem by id, within the caller's OWN org-group family; requires authentication. A cross-tenant id reads as null (not-found) AND trips the rootId tripwire server-side.

## What happens

Reads only — changes nothing.

## Who may call it

## Arguments

| Name | Type | Required | Notes |
| --- | --- | --- | --- |
| `id` | [ID](/types/#scalars) `ID!` | yes | The id of the record. |

## Returns

[InventoryItem](/types/InventoryItem/) — An inventory item: ONE per (Variant x LogicalFacility), carrying the CACHED bucket balances + the weighted-moving-average cost. Parent = the Variant; the other junction leg is the IMMUTABLE logicalFacilityId. The junction (variant x LF) is unique (a live duplicate is CONFLICT/IDENTITY_TAKEN naming the holder). styleType is BIRTH-STAMPED from the spine (immutable upstream): simple/kit IIs are STOCKED; service/bundle IIs are STOCKLESS price-carriers refusing quantity movements. Buckets are SIGNED decimal strings moved ONLY by the movement ops (receiveStock/adjustStock/reclassStock: one movement = ONE transaction; overcommit is allowed + ALWAYS evented, IV-i); available = on_hand − reserved, ALWAYS derived, never stored. Doom requires EVERY bucket exactly zero (CONFLICT/REFERENCED naming the non-zero buckets); deactivate is FREE and reversible. onOrderQty is a SIXTH field, NOT a bucket: the open quantity of the issued purchase orders for this junction, maintained by the purchase-order walks + the receipt post — never by movements, never inside available; a pre-walk row reads 0; the audit/repair pair (inventoryOnOrderAudit / repairInventoryOnOrder) stamps the derived truth over drift.
