Inventory Sync for WooCommerce allows to sync the stock of the products with the same SKUs between two WooCommerce stores.
✅ Allows to sync not only Stock quantity, but also Stock Status and Stock Management checkbox value.
✅ Product variations are supported (must have the same SKU as well).
✅ Instantly syncs stock changes when a product is purchased or edited via WordPress or an order is refunded or cancelled.
✅ Two-directional product stock sync is supported.
✅ Works with both regular WordPress sites and Multisite networks.
✅ An unlimited number of WooCommerce stores is supported.
✅ Allows you to exclude specific products (or only variations within specific products) from the sync.
✅ SKU or Slug product connection type (can be helpful when not every product on your store has an SKU, or when they have duplicated SKUs).
✅ Asynchronous syncing (significant performance boost when an order with a lot of products is placed).
✅ REST API requests are packed and sent in batches with the PHP Requests library, which gives another performance boost in every scenario; here is the benchmark.
