Running one WooCommerce store is simple.

Running multiple stores isn’t.

As your business grows, so does the amount of repetitive work—updating products, maintaining multiple dashboards, and keeping catalogs consistent across different stores.

Whether you operate multiple brands, wholesale and retail stores, regional or multi-language websites, franchises, or client stores, you can update products once and sync supported changes across every connected store.

Unlike traditional inventory sync plugins, Multi-Store Sync is built around a Google Sheets-first workflow. Your spreadsheet becomes the central workspace while FlexStock handles product management and synchronization in the background.

Why Multi-Store Sync?

Managing products separately across multiple WooCommerce stores is time-consuming and difficult to scale.

Multi-Store Sync simplifies that workflow by letting you manage products from one central workspace.

Instead of repeating the same updates on every store, your team can:

Manage multiple WooCommerce stores from one Google Sheet
Share products securely between connected stores
Reduce repetitive product updates
Keep supported product data synchronized
Keep stock levels aligned across every store that sells the same products
Maintain a consistent catalog across your business

WooCommerce Multistore vs. WordPress Multisite

Many store owners searching for a WooCommerce Multisite setup actually need something simpler: several stores that share one product catalog.

WordPress Multisite runs a network of sites from a single WordPress installation and database. All stores share one network, one codebase and one update cycle.
A multistore setup with Multi-Store Sync connects independent stores, each with its own install, domain, hosting, theme and checkout, and syncs the products you choose between them.

This gives you a multistore ecommerce platform on top of the stores you already run. There is no need to migrate to a Multisite network just to keep catalogs and stock aligned.

Why Google Sheets?

Google Sheets makes it practical to manage WooCommerce products in bulk.

Instead of editing products one by one inside WooCommerce, your team can work from a familiar spreadsheet to:

Update products in bulk
Collaborate with teammates
Review changes before synchronization
Manage multiple stores from a single workspace

FlexStock provides the Google Sheets integration, product management, and synchronization engine.

Multi-Store Sync extends that workflow by connecting your stores and securely distributing products between them.

How It Works

Multi-Store Sync uses a simple Source Store Destination Store workflow.

Source Store

A Source Store owns the products and controls what is shared.

From the Source Store, you can:

Create secure sharing tokens
Choose which products to share
Control which supported product fields are synchronized
Share products with one or multiple Destination Stores

Destination Store

A Destination Store receives products from a Source Store.

Simply add the shared token, import products, and continue receiving synchronized updates through FlexStock.

This architecture gives you full control over how products are distributed across your stores.

How to Sync Multiple WooCommerce Stores

Getting started only takes a few minutes.

Install and activate FlexStock.
Install Multi-Store Sync.
Connect FlexStock with Google Sheets.
Create a sharing token in the Source Store.
Choose which products to share.
Connect a Destination Store using the token.
Import products.
Continue managing products from Google Sheets while connected stores stay synchronized.

Multi-Store Inventory Management

Stock is usually the first thing to drift when the same products are sold in more than one store. With Multi-Store Sync, you update stock in the FlexStock Google Sheet on the Source Store, and connected Destination Stores receive the change automatically. Price changes and supported product deletions follow the same path, so every store works from the same inventory data.

FlexStock + Multi-Store Sync

Although they work together, each plugin has a different responsibility.

FlexStock

FlexStock manages:

Google Sheets integration
Product management
Supported product fields
Bulk product editing
Synchronization engine

Multi-Store Sync

Multi-Store Sync manages:

Store connections
Product sharing
Sharing permissions
Source Store and Destination Store workflow
Product distribution across connected stores

Note: Multi-Store Sync does not unlock FlexStock features. It extends FlexStock by adding secure multi-store connectivity and product sharing. Any product field unavailable in your FlexStock edition will also be unavailable for synchronization through Multi-Store Sync.

Privacy Policy

Appsero SDK does not gather any data by default. The SDK only starts gathering basic telemetry data when a user allows it via the admin notice. We collect the data to ensure a great user experience for all our users.

The only other time data is sent is if you choose to submit the optional deactivation feedback form.
