How to Seamlessly Integrate Shopify and Extensiv for Bundled Products

The Challenge: Bundles and Kits in Shopify 

Shopify merchants love bundles — it’s a proven way to increase average order value. But when those bundles hit your warehouse management system (WMS), things get tricky: 

• Shopify sends one SKU for a “bundle,” but the WMS needs to know the individual component SKUs to pick and ship. 

• Without a proper integration, you’re left either pre-kitting or manually splitting bundles (which destroys efficiency). 

• Most 3PLs handle this with one-off “fixes” — and that’s where errors and manual work creep in. 

Our Approach: Smart Integration Between Shopify and Extensiv 

Productiv solves this with a flexible, automated setup that aligns how bundles live in Shopify with how inventory moves through Extensiv. 

Here’s how we do it: 

1. Bundle Management in Shopify: 
   We help clients use bundle apps within Shopify that automatically break a bundle into its component SKUs to transmit those SKUs for order fulfillment to Productiv. 
   Example: Instead of sending one “3-month tea bundle,” Shopify tells Extensiv to pick three SKUs (Tea A, B, and C). 
   This approach keeps your bundles dynamic — no pre-kitting needed — and ensures accurate inventory tracking. 
2. Item Aliases in Extensiv: 
   Extensiv allows for item aliases, which map multiple Shopify SKUs (like bundles or kits) to the correct warehouse SKUs. 
   1. If detailed shipment tracking isn’t required, we can enable aliases to simplify order processing. 
   2. For clients who need SKU-level shipment detail, we recommend bundle logic in Shopify instead. 
3. Automated Sync & Go-Live Management: 
   Our team ensures every item, alias, and bundle syncs correctly across platforms before go-live. 

“The only thing left to do is set Shopify locations and turn on the syncs,” as our tech lead Monica said in one of our internal integration calls. We don’t go live until every item is properly received and mapped, ensuring a zero-error first day. 

The Result: Automation Without the Chaos 

By handling bundle logic where it belongs (Shopify) and maintaining clean SKU-level sync in Extensiv, our clients get: 

• Real-time inventory accuracy across sales channels 

• Faster order processing with fewer manual corrections 

• Flexibility to launch new bundle SKUs instantly 

• Confidence that every order ships correctly — no matter how complex the offer 

When to Consider This Integration 

This setup is ideal for: 

• Brands growing and looking to automate more processes with their 3PLs 

• Companies frustrated by inaccurate inventory or bundle tracking 

• Shopify merchants ready to scale without adding warehouse complexity 

• One caveat is that bundles functionality in Shopify does not work if the merchant is also using Shopify subscriptions
