Shopify Bundles or Bundle & Kit Stock?
Shopify Bundles is Shopify's own free app, and it already takes component stock when a bundle sells. If you only sell simple bundles in your online store, it may be all you need. Kizing is for the cases merchants report it doesn't cover.

From Shopify Community threads and App Store reviews dated 2023 to Jan 2026, and Shopify's Spring '26 notes (which improved bundle display and reporting). Shopify changes its apps often; check its current help pages before deciding.
Why channels matter
A bundle that only exists in the online store can't be sold safely on a marketplace or social shop: the channel sees a stock number that doesn't follow the parts. Kizing keeps the bundle an ordinary product and writes its stock number, so every channel reads the same count. See Other channels and the ledger.
Where Shopify Bundles suits you better
It is free, built by Shopify and runs inside your admin with nothing extra to install. For a store with a few bundles, one location and only the online store, that is a good choice and we'd say so.
Moving over
Recreate each bundle in Kizing (or import a spreadsheet), check the dry run, then remove the bundle from Shopify Bundles before you turn it on in Kizing so the components aren't taken twice.
