Shopify Admin Inventory Transfer Between Locations

Purpose

Transfers a specified quantity of inventory from a source location to a destination location using paired inventory adjustments (decrement source, increment destination). Used for inter-warehouse rebalancing, pre-positioning stock before a sale, or redistributing inventory after a location change. Replaces manual inventory transfer in Shopify Admin.

Prerequisites

• Authenticated Shopify CLI session: shopify store auth --store --scopes read_products,write_inventory,read_inventory
• API scopes: read_products, read_inventory, write_inventory
• Both source and destination must be active Shopify locations

Parameters

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | store | string | yes | — | Store domain (e.g., mystore.myshopify.com) | | sourcelocationid | string | yes | — | GID of the location to move stock FROM | | destinationlocationid | string | yes | — | GID of the location to move stock TO | | transfers | array | yes | — | List of {sku, quantity} objects to transfer | | dry_run | bool | no | true | Preview adjustments without executing mutations | | format | string | no | human | Output format: human or json |

Safety

> ⚠️ inventoryAdjustQuantities directly modifies inventory levels. Decrementing the source below zero is possible if the quantity exceeds available stock — the skill will warn but Shopify does not block negative adjustments. Run with dry_run: true to verify available quantities at the source before committing. This does NOT create a transfer order record in Shopify; it is a direct adjustment.

Workflow Steps

1. OPERATION: locations — query

Inputs: first: 50 Expected output: All locations with id, name — validate source and destination IDs exist

1. OPERATION: inventoryItems — query

Inputs: Batch lookup by SKU to get inventoryItem.id for each transfer SKU Expected output: Inventory items with current quantities at source location

1. Validate: for each SKU, confirm available >= quantity at source. Warn if not but proceed if dry_run: false

1. OPERATION: inventoryAdjustQuantities — mutation

Inputs: Two changes per SKU: { inventoryItemId, locationId: source, delta: -quantity, reason: "correction" } and { inventoryItemId, locationId: destination, delta: +quantity, reason: "correction" } Expected output: inventoryAdjustmentGroup { changes { delta, location } }, userErrors

Session Tracking

Claude MUST emit the following output at each stage. This is mandatory.

On start, emit:

╔══════════════════════════════════════════════╗
║  SKILL: Inventory Transfer Between Locations ║
║  Store:                        ║
║  Started:              ║
╚══════════════════════════════════════════════╝

After each step, emit:

[N/TOTAL]   
          → Params: 
          → Result: 

If dry_run: true, prefix every mutation step with [DRY RUN] and do not execute it.

On completion, emit:

For format: human (default):

══════════════════════════════════════════════
OUTCOME SUMMARY
  SKUs transferred:   
  Total units moved:  
  Warnings (low stock): 
  Errors:             
  Output:             inventory_transfer_.csv
══════════════════════════════════════════════

For format: json, emit:

{
  "skill": "inventory-transfer-between-locations",
  "store": "",
  "started_at": "",
  "dry_run": true,
  "source_location": "",
  "destination_location": "",
  "outcome": {
    "skus_transferred": 0,
    "units_moved": 0,
    "warnings": 0,
    "errors": 0,
    "output_file": "inventory_transfer_.csv"
  }
}

Output Format

CSV file inventory_transfer_.csv with columns: sku, product_title, inventory_item_id, source_location, destination_location, quantity_transferred, source_qty_before, source_qty_after, destination_qty_before, destination_qty_after

Error Handling

| Error | Cause | Recovery | |-------|-------|----------| | THROTTLED | API rate limit exceeded | Wait 2 seconds, retry up to 3 times | | SKU not found | SKU not in catalog | Log warning, skip transfer for that SKU | | userErrors on adjustment | Location not stocking item | Log error, skip SKU, continue | | Quantity would go negative | Transferring more than available | Log warning; abort SKU if dry_run: false |

Best Practices

• Always run with dry_run: true first — the skill verifies available quantities and shows exactly what will change.
• This creates raw inventory adjustments, not a transfer order. For audit trail purposes, add a note in the reason field and document the transfer separately.
• For large transfers (50+ SKUs), run during off-peak hours to avoid interfering with live inventory reads by the storefront.
• Pair with multi-location-inventory-audit to identify which locations have excess stock before deciding transfer quantities.
