## 説明

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](https://wordpress.org/plugins/stock-sync-with-google-sheet-for-woocommerce/)
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)**
 2.  * **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

### 🧩 Key Features

 * **Connect multiple WooCommerce stores:**
    Link your stores inside FlexStock Addon
   and manage syncing from one place.
 * **Centralized workflow with Google Sheets:**
    Keep your inventory workflow in
   Google Sheets (single tab or store-wise tabs).
 * **Flexible sync direction:**
    Choose how stock updates should flow based on your
   operations.
 * **Built for shared-stock scenarios:**
    When products overlap across stores, keep
   stock aligned across those stores.
 * **Non-technical setup:**
    Connect stores using store URL + authentication token/
   keys.
