SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Inventory counts often drift from what Shopify shows due to cycle count differences, delayed 3PL returns, or multi-location discrepancies, and manually editing each variant/location is slow and error-prone.

Core Features & Use Cases

  • Location- and variant-specific adjustments: Apply signed quantity deltas to the exact variant and inventory location so your on-hand numbers reflect reality.
  • Audit-friendly reconciliation: Record a structured inventory adjustment reason (and optionally link it to a reference document like a PO or cycle count).
  • Safe preview mode: Run a dry-run to generate the before/after view in the CSV output without committing mutations.

Quick Start

Run shopify-admin-inventory-adjustment with dry_run set to true for the affected SKUs and locations, then submit the same adjustments again with dry_run set to false to apply them to Shopify inventory.

Frequently Asked Questions about shopify-admin-inventory-adjustment

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fix Shopify inventory quantity mismatches across multiple locations?▼

Run a Shopify inventory adjustment in dry-run mode to generate a before/after CSV preview without committing mutations. After verifying the cycle count corrections, execute the same adjustments with dry_run disabled to apply the signed quantity deltas to your inventory.

How do I reconcile late 3PL returns posted to the wrong Shopify inventory location?▼

Yes, you can link a reference document during the Shopify inventory adjustment process. Recording a structured adjustment reason alongside reference linkage ensures your cycle count corrections and 3PL return postings maintain proper audit reconciliation.

What is the safest way to apply cycle count corrections to Shopify variant stock?▼

The Skill resolves inventoryItem IDs by executing productVariants querying against your Shopify store. Once the IDs are resolved, it performs the inventoryAdjustQuantities mutation using signed deltas and reason logging to correct variant stock at specific locations.

Why does my Shopify multi-location inventory adjustment require an inventoryAdjustGroup update?▼

You need the specific product variant SKUs and the target inventory location identifiers. The process queries productVariants to resolve inventoryItem IDs, then uses these to perform the inventoryAdjustQuantities mutation with signed deltas for accurate stock corrections.
