Description

Bundles that work exactly the way you want.

Flex Bundles gives you Shopify's native bundle features (real-time inventory, expanded checkout items) without locking you into an app widget. Two ways to bundle: 1. "Fixed" bundles work automatically. Add a product to cart and its components get added too. Works on Facebook and Instagram. 2. "Flex" bundles give you full control to build custom experiences (mix-and-match) with any design, logic, and pricing. Generate AI-ready prompts for Shopify's theme editor, or hand off to a developer.

New Shopify bundle features: real-time inventory, expanded items in checkout
Fixed bundles: pre-set variants, works on Facebook and Instagram
Flex bundles: develop or use AI to build mix-and-match bundles, any design
Custom data: line item properties, dynamic titles, images, attributes
Lightning-fast: native integration, no widget overhead, uses metafields

Flex Bundles & Robbie have been a game-changer for our store. The app is incredibly flexible and solved major challenges we were having with ShipStation integration and inventory management. It does exactly what other solutions couldn’t. Couldn’t be happier with our experience!

Robbie built the exact bundle experience we wanted and was so great to work with. The team built us an awesome custom byob bundle experience - which brings a lot of fun and functionality to our website. They also set up about 100 fixed bundles. Our AOV with bundles was well over double our non-bundle AOV.

Flex Bundles has been a game-changer for us. It’s exactly what we needed to create seamless, user-friendly bundles on our site. The app is super easy to use on the backend for non-technical team members, while still offering advanced customization options for developers to fine-tune design and functionality. It’s exceeded our expectations on every level, and we highly recommend it to any brand looking to elevate their bundling experience.

Flex Bundles is hands-down the best bundling app we’ve tried. It runs natively on Shopify, so setup and fulfillment are seamless. Great variety of bundle types, clean layouts, and easy theme integration. Super customizable—perfect for devs, too. Highly recommend.

Super impressed with Flex Bundles! We have tried many different bundling apps and solutions over the years, but this is by far the most extensive and flexible option out there. It utilizes Shopify's native bundling and Shopify Functions, making setup and fulfillment a breeze. Beyond offering a variety of bundling and discounting options, the app includes multiple layout options that can be easily installed in the theme editor. Plus, the layouts are extremely customizable and developer-friendly, allowing for even greater control over styling to match your site and brand. Well done!
