Shopify 3PL Integration Consultant — Extensiv & Beyond
Moving to a 3PL or fixing a broken fulfillment integration? We connect Shopify to your warehouse management system cleanly — no order gaps, no inventory drift, no manual reconciliation.
3PL Integrations Break Quietly — Then All at Once
Most Shopify brands moving to a 3PL underestimate the integration work. The 3PL has its own WMS. Shopify has its own inventory. Orders need to flow one way, tracking numbers the other. When it works, nobody notices. When it breaks, you have hundreds of angry customers and no clean data to fix it with.
Orders Not Reaching the Warehouse
Orders placed on Shopify never arrive in the 3PL’s system. Manual CSV exports are the “solution.” We eliminate this with reliable, real-time order push integrations.
Inventory Drift Between Systems
Shopify shows 50 units. The warehouse has 30. Nobody knows which is right. We implement bidirectional inventory sync with reconciliation alerts.
Tracking Numbers Not Updating
Orders marked “fulfilled” in Shopify with no tracking number. Customer emails your support team. We close the loop with automated tracking sync back to Shopify.
How We Build Your 3PL Integration
Discovery & Mapping
We map every data field between Shopify and your 3PL — order details, SKU mapping, location IDs, tracking events, and exception flows.
3PL Configuration
Configure your WMS (Extensiv, ShipBob, or custom) to receive orders correctly — carrier mapping, warehouse location rules, exception handling.
Integration Build & Test
Build and test the integration in staging with real order scenarios including partial fulfillment, split shipments, and returns.
Go-Live & Monitoring
Go-live with monitoring in place. We watch the first 48–72 hours of live orders closely and fix any edge cases immediately.
3PL Integration Deliverables
A complete, tested integration between Shopify and your fulfillment partner — not a connector app left to configure itself.
Data Mapping Document
Complete field-by-field mapping between Shopify and your WMS — used for implementation, testing, and future troubleshooting.
Order Push Integration
Real-time or near-real-time order push from Shopify to your 3PL with proper filtering (exclude digital, pre-orders, etc.).
Inventory Sync
Bidirectional inventory sync so Shopify always reflects what’s actually in the warehouse — with drift alerts if sync fails.
Tracking Number Sync
Automated tracking number push from 3PL back to Shopify, triggering Shopify’s native shipping confirmation email to customers.
Returns / RMA Integration
Return authorization flows between Shopify, customer, and warehouse — with restock triggers and refund automation where applicable.
Exception Handling Rules
Defined playbook for what happens when orders fail, inventory goes negative, or tracking doesn’t arrive on time.
UAT Test Plan
Structured user acceptance testing covering 20+ order scenarios before go-live — including edge cases your team hasn’t thought of yet.
Go-Live Support (72 hrs)
We’re on-call for the first 72 hours post-launch to catch and fix any live edge cases before they impact customers at scale.
Ready to Outsource Fulfillment — or Fix a Broken Integration
First Time Outsourcing Fulfillment
You’ve been self-fulfilling and you’re ready to hand it off to a 3PL. We make the transition seamless — no orders lost, no inventory surprises.
Current Integration Isn’t Reliable
Your Shopify–3PL connection works most of the time. You’re patching failures manually every week. We rebuild it properly so it just works.
Scaling Across Multiple Locations
Adding a second warehouse or 3PL partner? We build routing rules and inventory allocation logic so orders go to the right fulfillment node automatically.
Frequently Asked Questions
Which 3PLs and WMS platforms do you work with?
We have deep experience with Extensiv (formerly 3PL Central / Skubana), ShipBob, and custom WMS environments. For other platforms, we assess integration capabilities during scoping and let you know exactly what’s possible.
Do we need a developer, or can you handle the technical work?
We handle the configuration, mapping, and platform-native integration work directly. For custom API development beyond what platforms support natively, we scope and manage a technical resource — you don’t need to source one separately.
How long does a Shopify 3PL integration take?
A standard Shopify–Extensiv integration runs 3–5 weeks from kickoff to go-live. More complex setups with multiple warehouses, multi-channel feeds, or custom WMS configurations run 6–10 weeks.
What happens if something breaks after go-live?
Every engagement includes 30 days of post-go-live support. We monitor the integration, respond to failures, and fix edge cases that only appear at live order volumes. For ongoing managed support, we offer monthly arrangements.
Can you help us choose the right 3PL partner?
Yes. If you’re evaluating 3PL options, we can help you assess candidates based on their WMS capabilities, integration flexibility, and fit with your Shopify setup — before you sign a contract.
