Bundles.app provides an adaptable and intuitive bundle product tool – a fast, flexible pathway to more sales. Easily sell multipacks, fixed bundles or “mix and match” bundles that enable your customers to select options such as size or color.
Solid Bundles creates each bundle as a normal Shopify product, so it works with your theme, reports, and sales channels. Bundle stock counts only kits that are complete at one of the locations you chose. That number is displayed on the product; it does not block checkout. The bundle total is set server side with Cart Transform, so it cannot drift when your theme changes.
