See every feature424 Inventory Sync keeps stock levels consistent across products and variants that share a SKU. When inventory changes from sales or edits, it mirrors available quantity per location to all matches—automatically. It’s lightweight and focused (no bells and whistles) with a manual “Sync now” fallback.
Bundle Inventory Sync solves a gap in Shopify: when a bundle sells, component inventory is not automatically reduced. This app tracks which variants make up each bundle and deducts component stock with every order, keeping inventory accurate without manual work. Merchants define bundles by mapping a bundle variant to its components and quantities. Syncs trigger automatically on orders or manually via Sync Now.
