What it does
Synkro synchronizes inventory, product information and order workflows across Shopify stores, including listings that share stock within one shop. Setup requires an account; each shop needs a subscription after the seven-day trial.
Install Synkro in Shopify, then choose Create account under the option for syncing your own stores. SKU is the default stock identifier. To use barcodes, open Settings > Syncing identifier, select Barcode and Save. This setting applies across the account's connected stores.
Check duplicate identifiers before changing stock: separate listings with a shared SKU or barcode will follow the same quantity. After setup, change one item's inventory and check its matching listings. Standard matching cannot account for multiple distinct same-SKU products sold in one order; that case needs Master Inventory System.
Monthly subscriptions are charged in USD for each connected store, without usage-based fees.
| Plan | Per store/month | Product capacity and added controls |
