How to Sync Shopify Stores: Inventory, Product Data and Apps
To sync Shopify stores, you connect them with a sync app or integration that matches products by SKU or barcode and keeps inventory, product details and, where needed, orders aligned between stores. Shopify treats each store as separate, so stock sold in one store doesn’t change the count in another unless a tool updates it.
Merchants run several stores for different regions, brands, wholesale buyers or price points. Without syncing, the same item can sell twice, prices drift apart and teams waste hours repeating every product change in each admin.
Does Shopify Sync Stores Natively?
Shopify doesn’t automatically share inventory, products or orders between separate stores. Each store has its own catalog, stock levels and order history, even when the same company owns all of them.
Shopify Plus includes several expansion stores, but they’re still separate stores that need their own data, so syncing still takes an app or integration. Before adding stores at all, check whether Shopify Markets can cover your needs, since it lets one store sell in several countries with local currencies, languages and pricing, which avoids syncing entirely.
How to Sync Shopify Stores
Syncing works by linking each product in one store to the same product in another, usually through a shared SKU or barcode, then copying changes between them. Decide first which data needs to stay in step, because tools differ in what they sync.
| Data | Why sync it | Common approach |
|---|---|---|
| Inventory | Prevents overselling when stores share the same stock | Real-time sync triggered by orders, refunds, cancellations and restocks |
| Product details | Keeps titles, descriptions, images and tags consistent | Sync from a source store, with optional field exclusions |
| Prices | Keeps prices aligned, or applies set differences per store | Sync with pricing rules such as markups for a wholesale store |
| Collections | Keeps catalog organization the same | Collection sync in apps that support it |
| Orders | Sends orders to the store that fulfills them | Order forwarding or order export features |
| New products | Saves recreating items in every store | Automatic product creation or bulk imports |
Most stores sync in one of five ways. Dedicated multi-store sync apps link stores directly, inventory feed tools pull stock from one store into another, inventory or ERP systems act as a central hub, bulk import and export tools copy catalog data in batches and custom API integrations handle unusual setups.
The right setup depends on what you share. Stores selling the same physical stock need real-time inventory sync, while stores that only share a catalog may just need product updates on a schedule.
Shopify Store Sync Apps Compared
The apps below are common choices for syncing Shopify stores. Ratings, prices and features come from each app’s Shopify App Store listing at the time of writing and change often, so confirm current details before you install.
| App | What it syncs | Matching | Pricing | Rating |
|---|---|---|---|---|
| Syncio Multi Store Sync | Real-time inventory, product details, order forwarding and payouts | SKU or barcode | Free for up to 25 products; paid from $19 per month, with add-ons for orders and product settings | 4.7 (168 reviews) |
| Multi-Store Sync Power | Real-time inventory, product fields, collections and two-way multi-location stock | Flags SKU and barcode mismatches and duplicates | Free for up to 25 products per store; paid from $19.99 per month | 4.6 (151 reviews) |
| syncX: Stock Sync | Inventory, with real-time quantity sync, plus scheduled product feeds | SKU or barcode | Free plan for source stores; paid plans needed for automatic sync | 4.7 (900+ reviews) |
| Syncify: Multi-Store Sync | Inventory, products, variants, prices, SKUs, barcodes and collections | Not described on the listing | From $19.99 per month, based on product count | New, no reviews yet |
Syncio Multi Store Sync
Syncio links a source store to destination stores and syncs inventory in real time using SKU or barcode. It can also sync product details such as images, prices, tags and descriptions, forward orders to the source store for fulfillment and split revenue through payouts.
Plans are priced by how many products you import, from a free plan for 25 products to paid tiers for larger catalogs. Order syncing and some product settings are billed as separate add-ons, so factor those into the cost.
Multi-Store Sync Power
Multi-Store Sync Power, from EGNITION, updates inventory whenever there’s an order, refund, cancellation or restock, and syncs product fields, images, pricing and collections between connected stores. It supports two-way, location-level inventory sync and can create new products in connected stores automatically.
It includes tools that flag SKU and barcode mismatches and detect duplicates, which helps prevent wrong stock counts. Plans are priced by products per connected store, from a free plan for up to 25 products to paid tiers starting at $19.99 per month.
syncX: Stock Sync
syncX connects two stores when both have the app installed, using the source store’s public token to create a feed in the destination store. Products are matched by SKU or barcode, scheduled feeds update data such as quantities, and a real-time option updates quantities when stock moves in the source store.
Its real-time sync covers quantities only, not products, prices or orders. Each feed connects one source to one destination and one location, so two-way syncing needs a second feed in the other direction.
Syncify: Multi-Store Sync
Syncify is a newer app that syncs inventory, products, variants, prices, SKUs, barcodes and collections across Shopify stores, with real-time, bulk and scheduled sync options. It launched in 2026 and had no reviews at the time of writing, so test it carefully before relying on it.
How to Set Up Store Sync
Whichever app you choose, the setup follows the same logic. Getting the groundwork right prevents most of the problems merchants run into later:
- Choose a source of truth. Decide which store, or which inventory system, owns stock levels and product data, so changes flow in a predictable direction.
- Clean up identifiers. Give every variant a unique SKU or barcode, and make sure the same product uses the same identifier in every store.
- Decide one-way or two-way. One-way sync suits a main store feeding others, while shared stock sold from several stores usually needs two-way inventory sync.
- Choose which fields to sync. Exclude fields that should differ between stores, such as prices for a wholesale store or descriptions for a different language.
- Test with one product. Sync a single matching SKU, place a test order and confirm the stock change reaches the other store.
- Run an initial alignment. Update existing quantities across stores before turning on real-time sync, since some tools only react to changes made after activation.
- Turn on automation and monitor. Enable automatic or real-time sync, then check sync logs regularly for skipped or failed items.
Common Store Sync Problems
Most sync problems come from data issues rather than the apps themselves. Watch for these before and after you connect your stores:
- Duplicate or generic SKUs. Identifiers reused across several products, such as a generic size code, can cause wrong quantities or even endless update loops.
- Missing identifiers. Products without a SKU or barcode can’t be matched and won’t sync.
- One-way sync with shared stock. If only one store sends updates, sales in the other store won’t reduce stock at the source, which can lead to overselling.
- Location mismatches. Syncing the wrong location, or several locations into one, can make stock look higher or lower than it really is.
- Filtered products. Draft or archived products may be excluded by default, so check status filters if some items don’t sync.
- Overwriting intended differences. Syncing every field can replace store-specific prices, titles or descriptions you meant to keep different.
Sync Product Data in Bulk
Real-time sync apps handle ongoing changes, but setting up a new store or making large catalog changes is often faster in bulk. Exporting products from one store and importing them into another gives every store the same starting catalog before real-time sync takes over.
Bulkflow supports bulk import, export, field mapping and scheduled data updates for Shopify, WooCommerce and Wix, so you can export selected store data, import product data and update existing records across stores. It suits catalog setup and recurring batch updates rather than instant stock syncing between stores.
Conclusion
When you sync Shopify stores, the right tool depends on what the stores share, from real-time inventory for shared stock to product and price updates for related catalogs. Clean, unique SKUs, a clear source of truth and careful testing keep every store accurate as you grow. We hope this guide helps you sync your Shopify stores with confidence. If you need to copy or update product data across stores in bulk, you can explore Bulkflow.
