Selling across several channels makes stock levels hard to keep accurate. A sale in one store isn't reflected in the others, which leads to overselling, cancelled orders, and hours of manual spreadsheet updates. SyncPenguin watches inventory changes in your Shopify location and passes them on to your other connected channels as adjustments, so every store shows the right quantities without manual work.

How does it work?

The Shopify Inventory Quantities connector lets you automatically keep stock levels in your Shopify store in sync with your other sales channels and inventory systems. SyncPenguin matches products by SKU or barcode and tracks every stock change, including sales, restocks, and manual adjustments. It then applies those changes across your connected stores. You can sync Shopify with Square, WooCommerce, Squarespace, BigCommerce, Xero, Zettle, or even another Shopify store, in one direction or both.

Popular real-world use cases

• 
  Keep stock levels in sync between your Shopify online store and your Square point of sale, so in-store and online sales never oversell the same item.

  
• 
  Sync inventory quantities two-way between Shopify and WooCommerce when selling the same products on both platforms.

  
• 
  Share one pool of stock between a Shopify store and a Squarespace store, so every sale on either site updates the other automatically.

  
• 
  Sync inventory between multiple Shopify stores, such as regional or brand-specific shops that sell from the same warehouse.
• 
  Keep stock in sync across Shopify, Square, and WooCommerce at once with a many-to-one setup that uses a single source of truth for inventory.

  

  
• 
  Push stock level changes from Xero inventory to Shopify, so your accounting system and online store always show the same quantities.

  
• 
  Sync Shopify stock with your Zettle card reader when selling at markets, pop-ups, and events.

  
• 
  Migrate or expand to BigCommerce while keeping inventory quantities in sync with your existing Shopify store during the transition.

  
• 
  Sync only products with a specific Shopify tag, such as 'wholesale' or 'in-store', to a second sales channel and leave the rest of your catalog untouched.

  

Key features

Near Real-Time Updates

Product changes in Shopify trigger syncing automatically, so stock levels across your channels stay up to date.

SKU or Barcode Matching

Products are matched across stores by SKU by default. You can switch to barcodes if that's how you identify items.

Location-Based Stock

Choose which Shopify location to sync, so the correct warehouse or store inventory is always updated.

Smart Product Filters

Sync only selected SKUs or products with specific Shopify tags and keep everything else untouched.

Accurate Adjustments

Stock changes are synced as adjustments rather than blind overwrites, so simultaneous sales in different channels are all counted correctly.

Affordable & Scalable

With SyncPenguin you only pay for actual changes to your inventory quantities, regardless of how many products you initially have, or will have in the future.

Things to note

• The connector syncs inventory quantities only. Product details such as titles, prices, and descriptions are managed directly in Shopify.
• Products must already exist in Shopify with a matching SKU or barcode. SyncPenguin updates their stock but does not create or delete products.
• Each connection syncs one Shopify location. To sync several locations, add a separate connection for each location.
• SKUs (or barcodes, if barcode matching is enabled) should be unique in your store. Items that share the same SKU are flagged so you can fix them, rather than updated incorrectly.
• Product variants without a SKU (or barcode, when barcode matching is used) are skipped. Add one in Shopify to include them in syncing.
• Shopify inventory tracking is automatically turned on for synced variants, so quantities can be managed correctly.
• Connecting requires Shopify app credentials with read/write access to Products and Inventory and read access to Locations.

Frequently Asked Questions

How does SyncPenguin match products between Shopify and my other store?

Products are matched by SKU by default. If you identify products by barcode instead, you can enable barcode matching in the Shopify connection settings.

Can I sync inventory between two or more Shopify stores?

Yes. You can connect multiple Shopify stores and sync stock levels between them one-way or two-way. You can also combine them with other platforms like Square or WooCommerce.

Does SyncPenguin support Shopify stores with multiple locations?

Yes. Each connection syncs a location you choose, such as a warehouse or retail store. To sync several locations, add a separate connection for each one.

Will SyncPenguin create new products in Shopify?

No. SyncPenguin focuses on keeping stock quantities accurate. It updates inventory for products that already exist in Shopify with a matching SKU or barcode, so your catalog stays exactly as you set it up.

How quickly are inventory changes synced?

Product changes in Shopify trigger syncing automatically through webhooks, and SyncPenguin also checks for changes regularly. This keeps your stock levels up to date across channels in near real-time.

Can I sync only some of my Shopify products?

Yes. You can limit syncing to specific SKUs or to products with certain Shopify tags. All other products are left untouched.

What do I need to connect my Shopify store?

You need your shop's code name and credentials from a Shopify app with read/write access to Products and Inventory and read access to Locations. The SyncPenguin setup guides walk you through it in a few minutes.
