Shopify Guide to Switching Inventory to a 3rd Party Warehouse

Introduction

As order volume increases, many merchants decide to outsource storage and shipping. To make this transition successful, you must follow the correct process for switching inventory to a 3rd party warehouse in Shopify. If not configured properly, Shopify may continue routing orders to your old address, causing delays and stock issues.

This guide explains how to switch your inventory safely and efficiently.

Why Switch Inventory to a 3rd Party Warehouse

There are several reasons for switching inventory to a 3rd party warehouse in Shopify:

• Faster shipping and delivery
• Reduced workload
• Professional inventory handling
• Easy scaling during high demand

However, Shopify must be updated to reflect where the inventory is actually stored.

How Shopify Inventory Locations Function

Shopify uses locations to track stock. When an order is placed, Shopify checks which location has available inventory and assigns fulfillment automatically. That’s why switching inventory to a 3rd party warehouse in Shopify must be done at the product level.

Step 1: Add the Warehouse as a Location

1. Go to Settings → Locations
2. Click Add Location
3. Enter warehouse details
4. Save

This step registers the warehouse inside Shopify.

Step 2: Connect Products to the New Location

• Open a product
• Go to the Inventory section
• Enable the 3PL location
• Disable previous locations if necessary

This is essential for switching inventory to a 3rd party warehouse in Shopify.

Step 3: Update Stock Levels Accurately

Once stock is delivered to the warehouse:

• Edit inventory quantities
• Match them with the warehouse report
• Save changes

Correct stock levels prevent overselling.

Step 4: Remove Old Location from Products

If you no longer ship orders yourself:

• Disable old location access for products
• Or deactivate the location

This ensures Shopify focuses only on the 3PL after switching inventory to a 3rd party warehouse in Shopify.

Step 5: Verify Order Fulfillment Flow

Place a test order to confirm:

• Shopify assigns the new location
• The warehouse receives the order
• Fulfillment works properly

Testing is a crucial step.

Tips for a Smooth Transition

• Update products in batches
• Double-check inventory numbers
• Communicate with your 3PL partner
• Test before going live

These tips help while switching inventory to a 3rd party warehouse in Shopify.

Conclusion

Outsourcing fulfillment is a smart move, but only when Shopify is configured correctly. By carefully switching inventory to a 3rd party warehouse in Shopify, you ensure accurate stock tracking and smooth order processing. Follow the steps and verify everything for the best results.
