See every featureManaging multiple stores is time-consuming and error-prone. Hydra solves this by creating a seamless link between your stores; this allows you to manage one inventory pool across multiple Shopify installations. Hydra syncs product information, collection information and allows you to set override values, stock offsets, different pricing and more.
Multi-Store Sync Power keeps inventory, products, orders, and collections synchronized across all your connected stores. Inventory updates automatically in real time whenever there’s an order, refund, cancellation, or restock. The app syncs product fields, descriptions, images, metafields, and collections across connected stores without manual work. Paid orders copy to the store that ships, and tracking goes back.
