Multi-Store Sync

Running multiple WooCommerce stores (brands, branches, wholesale + retail, country-specific sites, etc) is great until inventory goes out of sync.

If you run more than one store, you often end up with:

• multiple admin dashboards
• multiple spreadsheets
• stock mismatches and overselling risk

Multi-Store Sync Addon for FlexStock extends the main FlexStock plugin, so you can now connect multiple WooCommerce stores and keep stock aligned using Google Sheets.

👉 FlexStock already helps you to manage WooCommerce products and stock from Google Sheets with real-time and two-way syncing. This addon adds what multi-store owners need next: store connections + cross-store stock consistency.

External Services

This plugin utilizes external services to function:

1. Connected WooCommerce Stores (REST API)
   • Service: Communication between your connected WordPress/WooCommerce websites.
   • Usage: To synchronize product inventory, pricing, and other data between stores.
   • Data Sent: Product details (ID, SKU, Stock, Price, Title, etc.) and authentication tokens.
   • Privacy Policy: Data is transmitted directly between the sites you manually connect. No data is sent to any third-party servers outside of your own connected store network.

Two common ways you can use it:

1️⃣ Multiple stores, different catalogs (multi-brand / multiple businesses): If you run several WooCommerce stores where each site sells different products (different brands, different categories, or separate businesses), inventory management usually becomes scattered.

Most store owners end up maintaining:

• separate WooCommerce dashboards, and
• separate Google Sheets for each store

🎯 What this addon solves: Multi-Store Sync lets you connect those stores so you can manage your inventory workflow from a single Google Sheets workspace (powered by FlexStock).

That means:

• Less repetitive work (no more updating the same type of stock data across multiple places)
• Easier inventory tracking across multiple WooCommerce stores
• A cleaner workflow for teams managing many stores

2️⃣ Multiple stores that sell the same products (shared products across sites) Some businesses operate more than one WooCommerce site, but many or few of the products are the same across those sites. For example:

• a main storefront + regional storefronts
• retail + wholesale storefronts
• a primary brand store + sub-brand storefronts under the same company

In these setups, the same product may appear on multiple websites, so stock needs to stay accurate everywhere.

🎯 What this addon solves: When the same product exists on more than one connected store, stock changes should not drift apart.

Multi-Store Sync helps keep stock consistent across connected stores where that product exists. So when stock changes in one store (after a purchase, restock, or an update via your workflow), the updated stock can be reflected on other connected stores too.

Simple example (easy to visualize):

• A product is listed on two stores with the same SKU.
• Let the total stock is 100.
• If 3 units are sold on Store B, stock becomes 97.
• Store A can also reflect 97, so both stores show the same available quantity.

This helps reduce overselling and keeps inventory counts consistent across your WooCommerce network.

Best practice: Use the same SKU for the same product on every connected store. This is the most reliable way to match products and sync stock accurately.

This Addon is perfect for

• Multi-brand businesses running separate WooCommerce stores with different catalogs
• Agencies managing inventory for multiple WooCommerce client sites
• Retail + wholesale setups where the same products must stay aligned
• Regional / country storefronts where stock must remain consistent across sites
• Companies with multiple storefronts (main store + sub-brand or storefront sites) selling overlapping products
