Keep Multiple Shopify Stores Perfectly in Sync
Running two, five, or fifty Shopify stores with shared inventory? A sale on one store should instantly update stock on all the others - but Shopify has no built-in way to connect stores. Multi-Store Sync Power links your Shopify stores together and synchronizes inventory, products, pricing, and collections in real time across every connected store. No spreadsheets, no duplicate work, no overselling.
Stop overselling
Inventory updates in real time across every connected store - on orders, refunds, cancellations, and restocks. No more selling what you don't have.
One product catalog, everywhere
Create or update a product on any store and it syncs to all others. Titles, descriptions, images, pricing, variants, and metafields - controlled per field.
Built-in safety net
Automatic discrepancy detection runs twice daily and reconciles inventory across all stores. Catches what real-time sync might miss.
No spreadsheets, no CSV imports
Connect stores with a single link key. Two-way sync, multi-location support, and up to 50 stores on one connection - fully automatic.
One Connection. Total Control.
Every Store Stays Accurate.
Link your Shopify stores with a single key - inventory, products, pricing, and collections sync automatically in real time. A built-in Safety Net catches discrepancies twice daily. No code changes, no CSV imports, no manual updates.
Real-time inventory synchronization
Inventory updates across every connected store the moment an order, refund, cancellation, or restock happens. Supports multi-location inventory, two-way sync, one-way sync, and sync-on-creation modes. Connect up to 50 stores on a single link key. The app processes inventory changes in seconds, not hours - so stock levels stay accurate across your retail, wholesale, and regional storefronts without manual reconciliation or CSV imports.
Safety Net - automatic discrepancy detection
Re-checks and reconciles inventory across all connected stores twice a day. Choose your discrepancy mode - main store as source of truth, or minimum quantity across stores. Catches what real-time sync might miss.
Product sync with field-level control
Choose exactly which fields to sync - titles, descriptions, images, tags, variants, pricing, status - and which to leave independent per store. Products are matched by SKU or barcode. New products auto-create in connected stores.
Custom pricing rules per store
Set pricing formulas per connected store - multiply, add markup, round, or apply custom logic. Supports compare-at prices and discount syncing. Retail, wholesale, and regional stores each show the right numbers automatically.
Sync exclusions - control what stays independent
Use tag-based rules to exclude specific products, collections, or metafields from syncing. Inventory, product, and collection exclusions are managed separately. Store-exclusive items stay isolated while everything else syncs.
Two-way sync - manage from any store
Make a change on any connected store and it propagates to all others. The app detects which store initiated the update and applies it everywhere else without creating loops or conflicts.
Collection and metafield sync
Sync manual and smart collections with product membership, sort order, and collection-level metafields. Product metafields - sizing charts, material specs, dimensions - stay identical across stores. Missing collections auto-create during sync.
Sync history and duplicate detection
Every change is logged - which store triggered the update, what changed, and when. Filter by inventory, products, or collections. Duplicate SKUs and barcodes are flagged before they cause problems.

The app does what it says on the tin and makes life a lot easier. The support is also great when you cannot figure something out. Once everything is set up correctly, it just hums along and you don't have to worry about it.
What a relief. Syncing two Shopify stores with this app works fantastic and the support is top notch!
Outstanding app and customer service. I was uncertain about integrating a new store and reached out to support. The support team not only guided me through the entire setup process but was incredibly patient—taking time across four meetings over three days to ensure I had everything right. That level of dedication made all the difference. Highly recommended.
The support team was incredibly helpful and accommodating throughout the process. Excellent customer service—thank you so much for your assistance! Highly appreciated
Good app, great support! Using for a few years. I am surprised that I didn't post a review earlier. I just contacted them with a question for the first time since setup a few years ago and got a perfect answer to solve my issue in seconds!

Frequently Asked Questions
Common questions about Multi-Store Sync Power - inventory sync, product updates, pricing rules, and multi-store setup.
Does Multi-Store Sync Power prevent overselling across Shopify stores?
Yes. The app synchronizes inventory in real time across all connected stores — every order, refund, cancellation, and manual adjustment triggers an immediate update. If Store A sells the last unit, Store B's inventory reflects the change within seconds. The built-in Safety Net runs a full reconciliation twice daily as a backup layer, catching any edge-case discrepancies before they cause oversells.
How do I sync inventory across multiple Shopify stores?
Install Multi-Store Sync Power on your primary store and connect your other stores using a shared link key. The app synchronizes inventory levels across all connected stores in real time — triggered automatically by orders, refunds, cancellations, and restocks. You choose the sync mode: two-way, one-way, occasional, or sync-on-creation. A built-in Safety Net re-checks inventory across stores twice daily to catch any discrepancies.
How many Shopify stores can I sync at once?
Up to 50 Shopify stores on a single link key. Most merchants connect between 3 and 5 storefronts — covering regional, wholesale, and multi-brand setups. For configurations beyond 50 stores, contact support.
Is Shopify inventory sync real-time or scheduled?
Real-time by default. Auto-sync triggers immediately when any connected store receives an order, refund, cancellation, or manual inventory update. You can also choose one-way sync, two-way sync, occasional sync, or sync-on-creation to match your workflow. Additionally, the Safety Net feature runs a full inventory reconciliation across all stores twice daily as a backup layer.
What happens when inventory levels don't match across stores?
Multi-Store Sync Power's Safety Net feature automatically detects and resolves inventory discrepancies. You choose the discrepancy mode: use the main store as the source of truth, or take the minimum quantity found across stores. For example, if Store A shows 10 units and Store B shows 3, the app aligns both based on your chosen rule — preventing overselling across storefronts.
Can I exclude specific products from syncing?
Yes. Use tag-based rules to exclude specific products, collections, or metafields from synchronization. Inventory, product, and collection exclusions are managed separately, so you can keep store-exclusive items, regional products, or test data isolated while everything else stays in sync.
Can I sync different prices to different Shopify stores?
Yes. Use the app's pricing formulas to define rules per connected store — for example, wholesale pricing on one storefront and retail on another. Supports markups, multipliers, rounding, compare-at prices, and discount amounts. This is especially useful for B2B, multi-currency, and international store setups.
What product data is synced between Shopify stores?
Inventory levels, product titles, descriptions, images, tags, pricing, discounts, variants, metafields, status, sales channels, and collections. You control exactly which fields sync and which stay independent per store. Products are matched across stores by SKU or barcode, and the app flags mismatches to prevent duplicates.
Does Multi-Store Sync Power support Shopify multi-location inventory?
Yes. The app supports multi-location inventory synchronization. Select specific store locations to include in sync, and inventory levels update per location across connected stores. This is ideal for merchants operating multiple warehouses or fulfillment centers.
Does the app sync Shopify metafields and collections?
Yes. Multi-Store Sync Power syncs both product and collection metafields — including dimensions, timestamps, file references, rich text, ratings, and URLs. Collections sync with product membership, metadata, sort order, and handle-based matching. Missing collections can be auto-created in connected stores during sync.
Can I sync Shopify inventory between stores in different countries?
Yes. Multi-Store Sync Power connects stores regardless of geographic location, currency, or Shopify market. Use pricing formulas to adjust prices per store — for example, wholesale pricing on one storefront and retail on another, or different markups for different regions. Inventory levels sync in real time across all connected international storefronts.
How much does Multi-Store Sync Power cost?
Multi-Store Sync Power offers a free Bronze plan for up to 25 products and a 7-day free trial on all paid plans. Paid plans start at $19.99/month and scale based on the number of synced products per connected store. Annual billing is available with a 20% discount.
