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!

We sell Hair Ties in 50+ colorways, so bundling has always been tricky. Customers want to mix and match loops, scrunchies, and clips, and most bundle apps we tried felt clunky or broke our storefront design. Flex Bundles fixed that. Our [build-your-own / gift set / collab] bundles now look like a native part of our store instead of something bolted on.

What stood out most was the team. [Name] and the Flex team [helped us set up X / built a custom Y / answered questions within hours], and it felt like working with a partner, not a support ticket queue. Since launching, we’ve seen [higher AOV / more bundle orders / a specific result].

If you have a big catalog and want customers to build their own sets without hurting the shopping experience, install this. We’re grateful to the team for making it so easy.
