Bundle & Kit Stock / Compare / checked Nov 2026
Bundle and kit inventory apps, sorted by reviews
We build Kizing: Bundle & Kit Stock, one of the apps on this page. It is new: not yet listed on the Shopify App Store in November 2026, with 0 reviews. So this list is sorted by each app's live review count, not by our opinion, and ours comes last.
First: Shopify's own free Bundles app
Shopify makes a free app, Shopify Bundles, that sells fixed bundles and multipacks built from your products. Try it first if your bundles are simple. Its listing has a 2.9 rating from 569 reviews (8 Nov 2026), and it doesn't describe how component stock is mapped, so check that it covers your channels and 3PL before you rely on it.
The apps, sorted by number of reviews
This page lists apps whose job is keeping bundle stock tied to the products inside. Discount-bundle apps (quantity breaks, bundle offers) are a different job and aren't included.
| # | App | Reviews | Rating | Free plan | Paid from | How bundle stock is kept |
|---|---|---|---|---|---|---|
| 1 | Simple Bundles & Kits | 830 | 4.9 | Yes, 3 bundles, 50 orders a month | $14 a month | Breaks each bundle into component SKUs and syncs stock with 3PL, WMS and ERP systems |
| 2 | Trunk ‑ Stock Sync & Bundling | 409 | 4.9 | No (14-day trial) | $39 a month (Pro, for bundling), rising with orders | Real-time stock sync across stores and channels, with bundling and kitting on Pro |
| 3 | Bundles.app ‑ Inventory Sync | 324 | 4.9 | No (free trial) | $19 a month (non-Plus) | Syncs bundle inventory with its products; unlimited bundles |
| 4 | Bundle Kit ‑ Inventory Sync | 75 | 4.7 | No (14-day trial) | $21 a month | Syncs kit stock, price and weight, and adds component SKUs to orders for 3PLs |
| 5 | Bundly • Mix & Match Bundles | 67 | 4.9 | No (free trial) | $29 a month | Mix-and-match packs; stock tracked per product |
| 6 | Krunch Bundle & Inventory Sync | 5 | 5.0 | No (free trial) | $9 a month | Two-way, real-time bundle and component stock across locations |
| 7 | Kizing: Bundle & Kit Stock (ours) | 0 | — | Yes, 3 bundles | $14 a month | Bundle stock follows its scarcest part on every channel; pick lists break orders into the parts to pack |
Which one fits
- Your 3PL needs each part as its own order line: Simple Bundles and Bundle Kit both put component SKUs on orders; Kizing doesn't (it gives a pick list instead).
- You want the most reviewed bundle stock app: Simple Bundles, with 830 reviews; Trunk (409) if you also sync stock across several stores.
- You only want a free plan: Simple Bundles and Kizing start free; the others offer trials.
- You sell the same parts in several bundles across POS and online: every app here keeps stock tied to parts; Kizing also shows stock per location and an hourly drift check. It is new and has no reviews yet; weigh that.
How we checked
Checked in one sitting on 8 November 2026, from each app's public Shopify App Store listing: rating, number of reviews, free plan and lowest paid price. We did not install the other apps for this page; the one-line descriptions come from their listings. Review counts and prices change, so check each listing before you decide.
