See every featureStockBridge 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.
Your ERP or inventory connector syncs thousands of updates a day — until the day it silently stops. Most merchants find out days later through oversells and stockouts. Sync Watchdog learns your store's normal sync rhythm and alerts you within minutes when it breaks: sync gone quiet, mass zero-outs, or impossible inventory jumps. Read-only, no ERP credentials, no customer data stored.
