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.
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.
