Overview
Kitenzo is a Shopify app for creating and selling product bundles, including mix-and-match and multi-step bundles. A merchant defines a bundle once and runs it in a theme, a headless storefront or custom React components. Pricing, validation and discounts are handled through Shopify's Cart Transform at checkout.
For Shopify brands
- Build bundles in a drag-and-drop visual builder and place them with the Shopify theme editor, with no developer needed.
- Apply percentage, fixed, tiered and volume discounts that price natively at Shopify checkout with no redirect.
- Use the React SDK or headless API to build custom bundle interfaces on the same bundle definitions.
How it works
A merchant installs the app from the Shopify App Store and builds bundles in the Kitenzo admin, or writes custom components with the React SDK. Kitenzo runs selection, validation, pricing and cart compilation, and bundles check out through Shopify Cart Transform. Both paths read the same bundle definition.
