DeltaSync Standard
Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureSelling bundles is great, but tracking individual item stock is hard. BundleShield simplifies this inventory process. When a bundle is sold, our app updates the stock levels of the individual SKUs. If a single item runs out of stock, the bundle updates to prevent overselling. Set it up once and let the sync engine run in the background. Stop manual stock adjustments and keep your inventory accurate.
DeltaSync keeps stock levels aligned across your Shopify stores. When inventory changes in your source store, DeltaSync updates the matching product in every connected store within seconds, matching items by SKU. Set an optional buffer to hold back safety stock on each target store.
