Flex Bundles

Flex Bundles is built for scaling brands that want their bundles to feel as polished as the rest of their store. Build fully custom, on-brand bundles (fixed, mix-and-match, tiered, and BOGO) on Shopify's native Cart Transform API. No rigid widgets or templates, so inventory stays accurate, checkout stays clean, and pages stay fast. A/B price testing, works on FB & IG, and custom data that maps to tools like ShipStation. On average, bundle orders from Flex Bundles merchants have 82.7% higher AOV.
