Bundly is a bundle builder app for Shopify that lets merchants create mix-and-match bundles and fixed product sets to increase average order value. It handles pricing, inventory, and checkout natively through Shopify's bundling APIs, with no draft orders or workarounds.

Bundly supports two main bundle types: mix-and-match bundles where customers pick their own products (build-a-box, pick-and-mix), and fixed bundles where you define a ready-made product set. Both types support product variants so customers can choose sizes, colors, or other options.

You can offer percentage discounts, flat amount discounts, or set a fixed bundle price. Discounts are applied automatically at checkout through Shopify's cart transform. No discount codes are used, so customers can still stack their own discount codes on top.

Yes. Bundly uses real-time inventory tracking with no syncing required. Inventory is managed at the individual product level, so you always have accurate stock counts and won't oversell. It works with Shopify's per-location inventory tracking.

It varies by store. In the median Bundly store, orders that include a bundle are about 40% larger than orders without one. How much your overall AOV moves depends on how many of your orders include a bundle. Our guide covers seven proven ways to increase average order value on Shopify.

Shopify's built-in Bundles app supports fixed bundles and multipacks, but does not offer a true mix-and-match builder: customers can't pick their own items. Bundly adds mix-and-match bundles, flexible discount types, built-in analytics, and B2B support, while still using Shopify's native bundling infrastructure for inventory and checkout.

Bundly is added to your store as a theme app block. You add it in the Shopify theme editor, with no code changes.

It also works with Shopify's free Horizon theme. In the block settings, choose the "Horizon" style to match your theme's colors, and turn on "Use Shopify's standard cart actions to add to cart" so the cart drawer opens when a customer adds a bundle.
