What Goes Wrong Without a Proper Integration
A bad 3PL integration does not fail all at once. It fails slowly — in ways that erode customer trust and waste hours of your team’s time every single week.
Inventory counts drift out of sync
Shopify shows stock the 3PL does not have. You oversell. Customers are disappointed and customer service spends hours managing fallout from discrepancies that should never have happened in the first place.
Orders misfire on edge cases
Bundles, split shipments, backorders, and address corrections break integrations that were only ever tested on simple single-item orders. Your team manually processes exceptions every day as a result.
Nobody knows how it actually works
The integration was set up by a developer or the 3PL’s onboarding team. Nobody on your side has documentation. When something breaks, you have no idea where to start — and the 3PL blames Shopify and Shopify blames the 3PL.
What We Deliver
End-to-end integration delivery — from initial scoping through post-launch support and full documentation handoff.
SKU and Inventory Mapping
Every SKU mapped between Shopify and your 3PL. Bundles, variants, kits, and virtual SKUs handled correctly so stock levels stay in sync from day one — not just on your simplest products.
Extensiv Configuration
Full Extensiv setup — order routing rules, carrier assignments, returns workflows, and warehouse-specific logic built to your exact operational requirements and not a template that was built for someone else.
UAT and Go-Live
Structured user acceptance testing before go-live. Every order flow tested: standard, bundle, split shipment, return, backorder. We find edge case failures in testing so your customers never find them in production.
Carrier and Rate Setup
Carrier accounts connected, shipping rates configured, and zone logic implemented for Canadian fulfillment. Customers see accurate rates at checkout and you get accurate settlement from your carriers.
Daily Reconciliation SOP
Documented process for your ops team to reconcile Shopify versus 3PL inventory daily. Catch discrepancies early, build the habit of proactive inventory management, and stop surprises before they reach customers.
Post-Launch Support
30-day hypercare period after go-live. We monitor order flow, troubleshoot issues, and tune configurations as real volume runs through the system. You are not on your own the moment we flip the switch.
Who This Is For
Brands moving to a 3PL for the first time
Leaving self-fulfillment behind. You need the integration done right without a six-month learning curve. Getting it right at the start is dramatically cheaper than diagnosing and fixing a broken integration after go-live.
Brands switching 3PL providers
Your current 3PL is not scaling with you. You need a clean cutover without losing order history, disrupting active shipments, or resetting the inventory accuracy your team has spent years building.
Brands with a broken integration
Stock numbers do not match. Orders are misfiring. The integration was patched together and nobody knows why it breaks. We diagnose, fix, and document it — then hand you the knowledge to maintain it going forward.
