Custom build-your-own bundle page with 1,275% bundle sales lift

Complex bundles, made simple. Any design or logic, with accurate inventory and clean fulfillment.

Flex Bundles helps high-volume brands launch bundles that are too complex for templated apps. Build fixed, mix-and-match, build-your-own, tiered, BOGO, and subscription bundles with your own design, logic, and pricing. Bundles run natively through checkout and fulfillment as real line items, so pricing, inventory, and order data stay accurate. You can A/B test bundle prices, sell fixed bundles on Facebook and Instagram, and send clean bundle data to ShipStation and your 3PL.

Fully custom bundle UX, logic, and pricing, built for AI-assisted development
Bundles expand into real line items with real-time inventory at every location
A/B test bundle prices to find the offers that convert and grow order value
Custom order data maps to ShipStation and your 3PL for clean fulfillment
Bundles Admin API and full-history analytics with CSV and API exports

The app is an absolute must for any store wanting to customize a bundle experience. We worked with the app dev to create our own custom bundling UX and system. This redesign alone has increased our bundle sales by over 450% in just over 2.5 months! The team is very responsive with any issues or questions you may have. Would highly recommend

This app is great right out of the "box", but Robbie and the team took it a step further and were able to create a BYOB bundle feature and page. This has been really successful for us on our site. We were able to get it up and running super quickly and they were able to personalize it even further after implementation. Highly recommend!

Flex Bundles has been a critical app for Giordano's DTC website, as we sell our products almost entirely in bundled formats. We gave the Flex Bundles team what seemed like a complex task in helping us re-create our product bundles as part of a broader DTC migration from our legacy platform to Shopify - they did an outstanding job delivering bundle functionality that's easy to edit and is driving meaningful revenue. They also handled a complex request to create BOGO functionality related to our bundles. Robbie has been awesome to work with - outstanding service and always seems to figure out a way to help us bring our ideas to life.
