About Bundle Kit

Bundle Kit enables businesses to easily build product kits, sync inventory of bundle and bundled products sold, and fulfill bundle orders.

Bundle ideas

  • Kits (e.g. Soft skin body routine 'kit', Day & night routine for dry skin ‘kit’)
  • Sets (e.g. Hand & lip balm duo 'set’, Eyelash & brow serum 'set')
  • Multipacks (e.g. ‘3-Pack' organic cotton T-shirts, ‘5-Pack’ comfort long sleeve tees)
  • Tiered products (e.g. ‘Basic’ fruit basket, ‘Premium’ fruit basket)
  • Boxes (e.g. Gift box, Subscription box, Mystery box)
  • Mix and match (e.g. 'Twin / Queen / King ' sized bed + 'With / Without' pillow)

How does it work?

  1. Assign a 'dummy' product as your bundle
  2. Specify products that make up each bundle variant
  3. Optionally set a discounted bundle price
  4. When a customer orders the bundle, Bundle Kit automatically syncs the inventory levels of both the bundle and the bundled products sold in real-time.
  5. Additionally, Bundle Kit automatically adds the individual bundled product SKUs as separate line items to the bundle order for ease of fulfillment.


Can I build a bundle with multiple variants?

Yes. You can build a bundle with multiple selectable variants each containing different products of different quantities.

Is coding knowledge required?

Nope! Simply install the app and immediately start building and selling your bundle kits.

What counts as an ‘order’ in the pricing?

An actual store order that may or may not be generated by the app. To determine if and how the inventory level of a bundle is to be adjusted, Bundle Kit inspects every single incoming order and computes in real-time.

Big thanks to Bundle Kit for helping offer products the way I needed them. I couldn't find another "bundling" app that would allow me to pull inventory from two variant items and also offer those two variants to be sold in a pair. But I was able to get in done with this app which was a HUGE lifesaver. The support was great at getting back to me quickly and provided helpful resolutions as I was setting everything up for my store. Lastly, I looked at quite a few different apps, and in my opinion, Bundle Kit has some of the best pricing, especially for my needs. I absolutely recommend giving this app a try and see if it works for you. It worked great for me!

We used this app to help us put a number of bundle kits together with our live inventory. It works really well. There was one issue with Shopify and the live inventory not updating and the support from these guys was first class. While we didn't solve the problem perfectly they helped us figure out a work around. Great app.

We had been looking for an app that offered easy bundles and kit support, as we offer a large range of kits on our store. This app has been working perfectly for our needs. Customer support is fast and efficient. Would definitely recommend to anyone trying to build kits and packages.
