Many 3PL software systems and warehouse API integrations connect to Shopify by importing every single order from your store. They have no way to filter by which fulfillment location an order is assigned to — they just pull everything.

This creates an immediate problem when you work with more than one 3PL: every warehouse sees every order, even orders that belong to a different location. Your 3PLs don't know which orders are theirs.

Order Fulfillment Guru solves this with an elegant workaround: give each 3PL its own dedicated Shopify store. OFG routes only the right orders into each store, so the 3PL can keep doing what it does — importing all orders — without the confusion.

⚠️ The Problem

Here's how the issue typically surfaces:

• You have two 3PLs: one on the East coast, one on the West coast
• You set up routing rules in Shopify so East coast orders go to 3PL A and West coast orders go to 3PL B
• Both 3PLs connect to your Shopify store via their software or API
• Both 3PLs import all orders from your store — neither can filter by assigned location
• 3PL A now sees West coast orders it shouldn't touch. 3PL B sees East coast orders that aren't theirs
• Fulfillment errors, duplicated shipments, and confusion follow

This isn't a rare edge case. Most off-the-shelf 3PL integrations work this way.

✅ The Solution: One dedicated Shopify store per 3PL

Instead of connecting multiple 3PLs to a single Shopify store, you create a separate, lightweight Shopify store for each 3PL. Order Fulfillment Guru connects your main store to each 3PL store and routes orders accordingly.

Here's how it works:

1. Your customer places an order on your main Shopify store
2. OFG's routing rules evaluate the order (based on geography, inventory, customer tag, product type, etc.) and determine which 3PL should fulfill it
3. OFG automatically sends that order to the correct 3PL's dedicated Shopify store
