StockUnison

StockUnison keeps inventory in sync across a merchant's Shopify stores. One store you nominate is the source of truth; every connected store follows it within seconds, matched by SKU. It is built for merchants who cannot afford a sync mistake: ambiguous SKU matches are refused instead of guessed, every connection starts in a dry run that shows each write before it happens, every change is logged including the skips, and nothing is ever created, edited or deleted in a destination store except available quantities. The free plan runs matching, dry run and drift verification against an unlimited catalogue without writing anything. Paid plans are flat, by number of live destination stores, and only the source store pays.
