What is the best app for bundling and kitting items?

Shopify Apps

Topic summary

Seeking a bundling/kitting app to manage kits and single SKUs (stock keeping units) with accurate inventory. Multiple solutions and approaches were shared.

Two bundle approaches:

  • Theme-driven bundles: shoppers pick items on a custom page; items added as separate order lines and a discount is applied.
  • SKU-based bundles (bundles as normal products): components tracked in the background; orders can be converted to component lines post-purchase for accurate stock.

Apps recommended:

  • Bundable ($18.50/month, 14-day trial) and Bundle Builder ($25/month, 30-day trial).
  • Bundleup: focuses on discount-code compatibility (bundle shown as one line), component-based inventory sync, and order line replacement for fulfillment.
  • Bundle Kit: builds on standard products; auto bundle inventory from component/variant stock.
  • Bundler – Product Bundles: mix-and-match features.
  • Simple Bundles: sell child SKUs independently or only within bundles; auto adjusts parent inventory; mix-and-match within Shopify’s 100-variant limit. Images and a screen recording were provided to show storefront/admin behavior.

Key clarification: Manual bundle pricing (not equal to sum of parts) is supported by multiple apps.

Status: No single “best” chosen; actionable options provided; discussion remains open.

Hi

There are 2 different types of bundle apps.

One type is creating custom pages in your theme and letting your buyers select different items as part of a bundle before check out. These are then added as individual order lines and a discount code applied.

Other type of bundler apps are ones like our bundleup app which are basically normal products which you then describe as a bundle or use variation options to add ability for buyers to select different sets or combinations. You track the components of the bundle in the background.

There are 3 main function of our app:

1. Discount Code Compatible

As the bundle is shown as one order line in checkout we don’t need to use any discount codes to adjust price. This lets the buyer add a discount code themselves that applies to whole order.

2. Inventory Management

Our app lets you connect up products to correct SKUs and we then update the bundle inventory based on the component stock level.

3. Order Fulfilment

When you sell one of the variations the master stock level won’t reduce automatically. What our app does is update the order post purchase by replacing the order line with the Single SKU as order line which then reduces that stock. This then feeds into point 1 above where it updates all linked variants.
