Automate Shopify Inventory with Flow

Can you automate inventory management with Shopify Flow?

Quick Answer: Yes. Shopify Flow automates inventory management with triggers like "Inventory quantity changed" and conditions like "quantity < 10." Common automations include low-stock alerts, auto-hiding out-of-stock products, reorder notifications, and tagging products by stock level. Available on Shopify plan ($79/month) and above.

Automating Inventory Management with Shopify Flow

Shopify Flow provides several inventory-specific triggers and actions for automating stock management. As of April 2026, these are available on Shopify ($79/month), Advanced, and Plus plans.

Inventory Triggers

Inventory quantity changed — Fires when stock level changes for any variant
Product added to store — When a new product is published
Order created — Allows inventory checks alongside order processing

Inventory Automation Examples

Low-Stock Alert

Trigger: Inventory quantity changed
Condition: Inventory quantity is less than 10
Action: Send email to [email protected] with product name, SKU, and current quantity

Auto-Hide Out-of-Stock Products

Trigger: Inventory quantity changed
Condition: Inventory quantity equals 0
Action: Unpublish product from online store

Auto-Republish Restocked Products

Trigger: Inventory quantity changed
Condition: Inventory quantity is greater than 0 AND product is unpublished
Action: Publish product to online store

Tag Products by Stock Level

Trigger: Inventory quantity changed
Conditions and actions:
- If quantity < 5: Add tag "critical-stock"
- If quantity 5-20: Add tag "low-stock"
- If quantity > 20: Remove tags "critical-stock" and "low-stock"

Reorder Point Notification

Trigger: Inventory quantity changed
Condition: Inventory quantity is less than reorder point (stored in product metafield)
Action: Create a draft order for the supplier with reorder quantity
Action: Send Slack notification to #inventory channel

Multi-Location Inventory

For stores with multiple locations (warehouses, retail stores), Flow can route inventory actions based on location:

Transfer stock between locations when one falls below threshold
Route orders to the nearest fulfillment location based on customer shipping address
Alert specific warehouse managers based on which location triggered the low-stock event

Limitations

Shopify Flow cannot modify inventory quantities directly (it can tag, notify, and trigger, but not adjust stock counts)
For automated purchase order creation, a third-party inventory app (Stocky, Inventory Planner) connected to Flow is needed
Flow processes events within seconds but cannot batch multiple inventory changes into a single workflow run
Inventory triggers fire per-variant, not per-product (a product with 10 variants may trigger 10 separate workflow runs)
