Spark Bundles App & Upsells

Project Overview

Spark Bundles & Upsells is a product bundling and upsell engine that helps merchants increase average order value. Built with Node.js, Remix, and Shopify Polaris, it leverages Shopify Functions and Checkout UI Extensions to power dynamic bundle pricing and cart-level upsells. Merchants can create fixed, BOGO, mix-and-match, and volume bundles, customize the bundle design and product display, and track performance and revenue from a single dashboard — no code required.
