If there’s one lever that consistently moves the needle on revenue without needing more traffic, it’s bundling. Grouping complementary products together — at a slight discount or as a value-add — encourages shoppers to buy more per visit, clears slow-moving inventory, and makes your store feel more curated. The tricky part is picking the right app to make it happen, since bundling touches everything from your product pages to your checkout and inventory sync.
Here are five of the best product bundle apps on the market right now, and what makes each one worth a look.
1. Vitals
Vitals is best known as an all-in-one marketing suite, and its Product Bundles feature is one of over 40 tools bundled (no pun intended) into a single app and subscription. Instead of installing a dedicated bundling app, you can turn on bundles alongside upsells, reviews, currency converters, and more — all managed from one dashboard.
What stands out:
- Create “Frequently Bought Together” style bundles or fixed multi-product packages
- Flexible discount rules (percentage, fixed amount, or tiered by quantity)
- Bundles render natively on the product page without a jarring popup
- Since it’s part of the broader Vitals suite, you’re not stacking multiple app subscriptions to run a full conversion stack
Best for: stores that want bundling as one piece of a larger conversion-optimization toolkit rather than a single-purpose app.
2. Bold Bundles
Bold Bundles (from Bold Commerce) is one of the longest-standing names in the bundling space, and it’s built for merchants who want serious flexibility. You can create fixed bundles, mix-and-match bundles, or “build your own box” style offers where customers pick from a set of eligible products.
What stands out:
- Deep customization of bundle logic, including conditional pricing
- Strong inventory syncing so bundle components stay accurate
- Works well for stores with large catalogs and complex product relationships
Best for: established stores with more complex bundling needs, like build-your-own gift sets or subscription-style boxes.
3. Zoorix Bundles & Upsell
Zoorix has built a reputation for combining bundling with cross-sell and upsell widgets in one clean package. It’s a favorite among smaller and mid-sized stores because it’s easy to set up without a developer.
What stands out:
- Drag-and-drop bundle builder with live preview
- “Frequently Bought Together” widgets that use purchase-history data
- Volume discount and quantity-break options alongside bundling
- Responsive support team, which matters a lot for merchants without in-house dev resources
Best for: growing stores that want bundling and upselling in one lightweight app.
4. Frequently Bought Together (by Code Black Belt)
This app has quietly become a go-to for merchants who specifically want the Amazon-style “customers who bought this also bought” bundle widget. It leans on both manual curation and algorithmic recommendations to suggest bundle combinations.
What stands out:
- Machine-learning-based product recommendations that improve over time
- Simple, familiar UI for shoppers already used to seeing this pattern elsewhere
- Solid track record and a long list of reviews, since it’s been around for years
Best for: stores that want a proven, recommendation-driven bundling widget without much manual configuration.
5. PickyStory
PickyStory takes a slightly different approach by focusing on multiple bundle formats in one app — including post-purchase upsell bundles, “build a bundle” pages, and mix-and-match kits — all aimed at merchants who want to experiment with several bundling strategies at once.
What stands out:
- Several distinct bundle types (not just one format) in a single app
- Dedicated bundle landing pages that can double as marketing assets
- Detailed analytics on which bundles are converting
Best for: merchants who want to test different bundle formats to see which resonates with their audience.
How to Choose
Before committing to any bundle app, think about three things:
- Catalog complexity. A store with a handful of SKUs doesn’t need the same horsepower as one with thousands of variants.
- Existing app stack. If you’re already paying for five different conversion apps, an all-in-one option like Vitals might simplify your stack and your bill.
- Bundle format. Decide whether you want fixed bundles, mix-and-match, or algorithmic “frequently bought together” widgets — not every app supports all three equally well.
Bundling is one of the simplest ways to increase average order value without discounting your way into thinner margins. Whichever app you choose, start with one or two high-intent bundles, watch the data, and expand from there.
