See every featureCatalogSync eliminates the manual work of sharing products between Shopify stores. Suppliers can share their catalog with resellers in a one-way sync, while inventory stays synchronized automatically from supplier to reseller. Resellers set custom markup rules during import and manage products from multiple suppliers in one dashboard.
StockBridge keeps inventory in sync across all your stores automatically. When stock changes in one store after an order, refund, or restock, quantities update in real time on every connected store. Match products by SKU or barcode, set buffer stock, and choose one-way or two-way sync per store or product group. See drift reports and a full activity log so you always know what changed and why.
