5X AOV | 2X Conversions | $30M+ Additional Revenue
In this blog, I’ve reviewed the best Kaching Bundle alternatives for Shopify stores. While Kaching Bundles is a great option for a Shopify product bundle app, there are multiple reasons you might be looking for alternatives. I have reviewed 7 such Shopify bundle apps, such as Fly Bundles, Easy Bundle Builder, Pumper Bundles, Koala Bundles, Rapi Bundles, Moon Bundles, and Appstle Bundles. I have compared these apps basis key product bundle feature requirements, pricing, pros & cons.
Based on the evaluation, Fly Bundles emerges as a good Kaching bundle alternative. However, there are reasons you may choose another bundle app in the list, and I’ve highlighted these too. If you are specifically having the requirement of creating a mix & match bundle, then Easy Bundle Builder is a clear winner. Anyway, let's dive in.
Fly Bundles is a Shopify bundling app designed to help merchants increase AOV through product bundles, quantity breaks, and frequently bought together offers. The app emphasizes flexible discounts, customizable bundle widgets, and analytics to help merchants measure bundle performance. Overall, it is a good alternative to the Kaching Bundles app.

Fly Bundles is the most dependable Kaching Bundles alternative when you want a clean, guided way to launch fixed bundles, volume-style quantity breaks, and frequently bought together upsells, and then improve performance with built-in analytics. The setup flow is easier to operationalize, and the customization depth (design controls, translations, personalization, stock handling) makes it feel complete without becoming overwhelming.
One thing to note is that Fly Bundles does not currently offer a mix-and-match bundle builder. If that's a feature your store relies on, see Easy Bundle Builder below. It's purpose-built for that use case.
Easy Bundle Builder is a multi-step mix-and-match bundle builder and a strong Kaching Bundles alternative for this use case. It is designed to let shoppers curate their own bundles. It supports multiple layouts (full-page and product-page templates) and is geared toward build-your-own boxes, gift kits, and advanced bundling logic.

If mix-and-match bundling is a priority for your store, Easy Bundle Builder is the tool built specifically for that. It fills the exact gap Fly Bundles leaves by enabling multi-step and mix-and-match bundle journeys with flexible pricing rules and conditional logic. Inventory sync and itemized checkout behavior make it especially strong for stores that need operational accuracy.
Pumper Bundles Quantity Breaks (Profit Pumper) is a bundling and discount app focused on increasing AOV through quantity breaks, volume discounts, and incentive-style promotions. It is one of the more well-known Kaching Bundle alternatives.

Pumper works well when your bundle strategy is discount-driven: quantity breaks, tiered offers, BOGO, and free gifts. It’s a practical alternative for stores that want promotions that increase cart size without needing a full build-your-own experience.
Koala’s Upsell and Bundle app combines bundling and quantity discounts with one-click post-purchase upsells and urgency-style storefront elements. It is a reliable Kaching Bundle alternative.

Rapi Bundles Builder & Upsells is a broad bundling toolkit with many bundle types plus optimization tools like A/B testing and AI recommendations. Rapi again is a strong Kaching Bundles alternative contender.

Moon Bundles Cart Drawer Upsell is a Kaching Bundles alternative that focuses on bundling plus cart-drawer and cart-upsell widgets, designed to increase AOV closer to checkout.

Appstle Bundles & Upsells is a bundling app from Appstle that supports multiple bundle types and deeper operational features like APIs, webhooks, and POS integration.

Product bundles can dramatically increase average order value. A well-placed bundle often turns a single-product purchase into a multi-item order.
Many Shopify stores use Kaching Bundles & Upsells to implement bundle offers and upsell flows. However, when reviewing merchant feedback on the Shopify App Store, some recurring concerns appear in lower-rated reviews. These reviews don’t represent every merchant’s experience, but they highlight common situations where store owners begin exploring alternative bundle apps.
Several merchants mention unexpected charges or billing confusion after uninstalling the app or during the trial period. In some reviews, store owners report being charged after believing they had already cancelled their subscription or before their trial period ended.
While billing is often tied to Shopify’s app subscription system, these experiences can still lead merchants to look for tools with clearer pricing structures or billing transparency.
Another point raised in reviews is theme compatibility. Some merchants reported that bundle widgets did not display correctly on their storefront or required additional technical support to integrate with their theme.
For merchants running heavily customized themes, even small integration issues can slow down deployment, which is why some store owners prefer bundle apps designed to work more seamlessly across different storefront setups.
A few merchants have reported technical issues affecting how bundles behave in the cart. For example, reviews mention cases where bundles were configured to add multiple products but only added one item intermittently.
Because bundle logic directly impacts pricing, inventory, and order value, merchants tend to be particularly cautious about reliability in this area. When issues appear, some store owners begin evaluating other apps with simpler or more predictable bundle behavior.
Support feedback in reviews is mixed. Some merchants praise helpful interactions with the support team, while others describe slower responses or situations where issues took longer than expected to resolve.
For merchants operating active stores, quick troubleshooting can be critical—especially when bundle offers affect checkout behavior or promotions running on live traffic.
Cost is another reason some merchants explore alternatives. A few reviews mention that the monthly price feels high when the store only needs a single feature such as volume discounts or basic bundles.
As a result, smaller stores or early-stage brands sometimes look for lighter bundle apps that focus on a narrower set of features at a lower price point.
Overall, Kaching Bundles & Upsells remains a popular Shopify app, but merchant reviews suggest that certain stores eventually look for alternatives due to billing clarity, integration challenges, feature complexity, or pricing relative to their needs.
Product bundles can dramatically increase average order value. A well-placed bundle often turns a single-product purchase into a multi-item order.
Kaching Bundles & Upsells is a Shopify bundling app used to create a wide range of bundle offers and upsells, including fixed bundles and true mix-and-match discounts. It’s typically used by merchants who want advanced discount rules, flexible bundle types, and customization plus analytics in one tool.
Kaching is a strong choice when you need one app that covers many bundle types, especially true mix-and-match plus advanced pricing rules and analytics. The tradeoff is simplicity: merchants who want faster setup and a tighter workflow often prefer more focused alternatives
We evaluated each Shopify bundle app using a mix of official Shopify listings, documentation, feature pages, and merchant feedback. The goal was to identify which apps provide the most reliable alternative to Kaching Bundles for different types of stores.
Different stores need different bundle mechanics. Fixed bundles work well for product kits, while mix-and-match builders allow customers to create custom bundles.
Most merchants prefer bundle apps that install quickly without developer help.
Advanced bundle apps support fixed pricing, tiered discounts, and quantity breaks.
Bundle analytics help merchants identify which promotions actually increase AOV.
Always check compatibility with subscription tools, loyalty programs, and email marketing apps.
Bundle setup often affects the storefront. Responsive support can make troubleshooting much easier.
For most Shopify merchants, Fly Bundles is the best Kaching Bundle alternative. It offers a clean interface, guided bundle creation, flexible discount logic, and analytics to track performance.
However, if your store depends on mix-and-match bundles, Easy Bundle Builder is the stronger option. Its multi-step builder allows customers to create custom bundles and gift sets with far more flexibility.
The remaining apps i.e., Pumper, Koala, Rapi, Moon, and Appstle, each serve specific use cases such as quantity discounts, upsells, or subscription bundles.
The best next step is to try your top choice on a free trial and see how it performs with your actual product catalog. All the best!
FAQ - Kaching Bundles Alternatives
Top Kaching bundle alternatives include Fly Bundles for fixed bundles and analytics, Easy Bundle Builder for mix-and-match, and Pumper Bundles for quantity breaks. Fly Bundles stands out with guided setup, variant customization, and revenue tracking, making it ideal for most stores transitioning from Kaching—except mix-and-match needs, where Easy Bundle Builder excels with multi-step builders and inventory sync. Test Fly's free plan first to replicate 80% of Kaching bundles without setup hassle.
Kaching bundles offer mix-and-match via volume discounts, but Fly Bundles provides superior guided creation, design controls (fonts, swatches), and stacking discounts without complexity. Unlike Kaching's broader types, Fly focuses on fixed bundles, quantity breaks, and frequently bought together upsells with parent product sync and out-of-stock handling. Shopify stores see easier AOV lifts (e.g., dynamic pricing) using Fly's analytics dashboard over Kaching's.
Most Shopify bundle apps require bundles to be recreated when migrating between apps. However, setup is typically quick because bundles are created directly within the Shopify admin
Using Kaching Bundles starts with enabling the app embed in your theme, then picking products or collections to bundle. From there, set your discount type—like fixed price for a "buy 2 get 1 free" deal, dynamic percentage off, or volume rules for quantity breaks and tweak the widget's look with colors, swatches, or text. For mix-and-match, turn on "volume discount with other products" to let customers swap items while keeping the savings. Preview on a test page, publish, and watch the analytics dashboard for conversion lifts position the widget above "Add to Cart" for best results, and sync parent products to handle stock changes smoothly
Yes, Kaching Bundles discount codes stack with order-level promos through Shopify's cart transforms, but not on the same product items. For example, apply a 10% bundle discount plus a storewide code; just test in cart preview to avoid surprises. Fly Bundles handles this just as reliably, often with less hassle for scaling stores.
Switch to a Kaching bundle alternative if you need simpler analytics, better widget customization, or cost savings—Fly Bundles starts free for dev stores vs. Kaching's $59.99/month top tier. Avoid if mix-and-match is core; opt for Easy Bundle Builder's conditional logic and SDKs instead. Migrating bundles requires recreation, but most apps like Rapi Bundles import via Shopify admin in under an hour
