Connecting Shopify to Your First 3PL
A guide for Shopify sellers moving fulfillment to a third-party logistics provider for the first time. Checkout and shipping notifications work the same way for your customers. What changes is where the order goes to get picked, packed, and shipped, and InfiPlex is what keeps Shopify and the 3PL's WMS talking to each other.

What actually changes
What Changes in Shopify, and What Doesn't
Your Shopify store keeps working the same way for customers. What changes is where fulfillment orders go after checkout. Instead of a person on your own team packing the order, the order needs to reach your 3PL's warehouse management system, get picked and packed there, and report tracking back to Shopify so the customer gets their shipping notification.
How it connects
How InfiPlex Connects Shopify to a 3PL
The same connection pattern applies whichever 3PL you choose.
-
Shopify Stays Connected as Normal
Your existing Shopify integration keeps running exactly as it does today.
-
Orders Route to the 3PL
The 3PL Connector sends fulfillment orders straight to your 3PL's WMS.
-
Location Routing Decides Which Orders Go Where
If you're running the 3PL alongside any in-house fulfillment, Shopify Location Router splits orders between them by rule.
-
Tracking and Inventory Sync Back Automatically
Shopify always reflects what's actually in stock and shipped, with no manual updates.
Choosing a partner
Choosing a 3PL
Most Shopify sellers moving to a 3PL for the first time choose based on location, pricing, and the systems the 3PL already supports. Whichever 3PL you choose, InfiPlex's job is making sure Shopify and the 3PL's WMS stay in sync without you managing the connection by hand.
Going live
Going Live Without Disrupting Orders
InfiPlex can run your 3PL connection alongside your existing fulfillment process, so you can test the flow with a small batch of orders before moving everything over.
