Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureOur app allows merchants to combine and synchronize inventory across multiple product variants, helping manage stock more efficiently. Instead of tracking inventory separately for each variant, merchants can group selected variants to share the same stock quantity. This is especially useful for products that represent the same physical inventory but are sold under different options or listings.
StockPool helps merchants sell products that share the same parts, materials, blanks, or ingredients. Create reusable components, connect them to Shopify products, and build recipes that calculate sellable inventory from the limiting component. StockPool keeps managed product inventory aligned with component stock and gives teams a clear sync log for support.
- Create groups of multiple variants that share a common inventory stock
- Set different stock reduction values for each variant based on inventory usage
- Automatically mark linked variants as sold out when shared stock reaches zero
- Track shared inventory for kits, bundles, and made-to-order products.
- Build product recipes that calculate sellable stock from limiting components.
- Sync managed Shopify inventory when component stock changes.
- Prevent overselling of products with shared components
