Stop fighting your bundle app

Why Flex Bundles

A/B price testing on bundles

Full control over bundle pricing lets you run true A/B price tests to find the offers that convert best, something that isn't possible with other bundle apps.

Developer-friendly, no rigid templates

Full control over how your bundles look, behave, and are priced. Build on a developer-friendly foundation instead of being forced into a rigid template.

Every bundle type, including BOGO

Fixed, mix-and-match, tiered, BOGO, and gift-with-purchase bundles, all from one app that scales with your business.

Bundles Admin API

Create and update bundles from your own scripts and systems: sync from a PIM, build seasonal bundles in bulk, and wire bundle management into the catalog tooling you already run.

Rules that guard every order

Price floors, component counts, and eligible-product rules are enforced in the cart and again at checkout, so hand-crafted cart requests can never break your margins.

Maps to ShipStation & your 3PL

Every bundle carries custom data attributes that map to exactly what tools like ShipStation and your 3PL need, so orders flow through to fulfillment cleanly.

Real-time inventory sync

Bundles work natively with Shopify, so inventory stays accurate in real time at every location and never drifts out of sync across your bundles and their components.

Expanded line items in checkout

Bundles expand into their individual line items at checkout, so customers, your team, and your fulfillment tools all see exactly what's in every order.

Every channel, every currency

Bundle orders from TikTok Shop and the Shop app expand correctly, and prices convert in multi-currency checkouts so customers pay exactly what they saw.

One-click bundle reorder

Customers can rebuild a previous bundle from their saved selections, turning a good first order into a repeat purchase.

Full-history analytics & exports

See how every bundle performs with unlimited order history and AOV lift per bundle, then take the numbers anywhere: CSV export, an analytics API for your dashboards, and order-level data stored in your own store.

Unlimited bundles & bundle sales

No caps. Create as many bundles as you want and sell as many as you can, on a plan that scales with you instead of throttling growth.
