• Streamline stock management: Automated syncing saves time and reduces errors by updating stock levels without manual input.
• Scale efficiently: For businesses expanding to new regions or channels, inventory syncing ensures smooth, scalable operations.

In short, syncing inventory correctly can help you streamline your inventory management and avoid any unnecessary errors or problems.

Can You Sync Inventory Between Two Shopify Stores Without an App?

Yes, it is possible to sync inventory between two Shopify stores without using an app, but these methods typically require more manual effort or technical skills. Here are two common options for achieving this:

Option 1: CSV export/import for one-time syncing

This method allows you to manually export your inventory data from one store and import it into the other. It’s best suited for initial setup or occasional inventory updates, but not ideal for ongoing, real-time syncing.

Here are 4 steps to sync inventory via CSV export/import:

Step 1: Log in to your first Shopify store’s admin panel. Navigate to Products > Inventory.

Step 2: Click the Export button and download your current inventory as a CSV file.

Step 3: Log in to your second Shopify store’s admin dashboard. Go to Products > Inventory and click Import.

Step 4: Upload the CSV file and review the preview. Start the import to update your inventory quantities in the second store.

Option 2: Use Shopify API to sync manually (developer-friendly)

Manual inventory sync Shopify using the Shopify API is a more technical but highly flexible method suited for businesses with programming resources or development teams. Instead of relying on third-party apps, developers create custom scripts or applications to automate inventory updates between stores.

While it demands initial setup and ongoing maintenance, it offers the advantage of a tailored syncing process that perfectly fits your operational needs without recurring app fees.

However, managing concurrency, ensuring data accuracy, and dealing with API rate limits are important considerations when building a custom inventory sync solution via Shopify API.

Also, keep in mind that Shopify has a variant limit per product, which can affect how you structure and sync complex product data.
