We make one of the apps on this page, so read it with that in mind. Prices and features of other apps come from their Shopify App Store listings, checked on November 14, 2026. Plans change: check the listing before you decide.
On this page
Kaching Bundles is one of the most-reviewed bundle apps on Shopify, with 6,720 reviews and the Built for Shopify badge. Volumo is our app: it does quantity breaks, buy X get Y, spend more save more, fixed bundles and free gifts. If quantity breaks are most of what you use Kaching for, here’s the comparison.
The short version
- Pick Volumo if you mainly need quantity breaks, BOGO, simple bundles and gifts, applied by Shopify at checkout, and you’d rather not have a plan that steps up with tracked revenue.
- Pick Kaching if you need build-a-box, subscription boxes, mix-and-match variations, custom CSS and HTML or its larger set of upsell tools, or you value its long review history.

When to stay on Kaching
If you use build-a-box, subscription bundles, mix-and-match beyond counting products together, or you’ve customized its layout with CSS, Volumo would be a step back. Kaching’s review count and Built for Shopify badge also count for something: it’s a mature product.
When Volumo is enough
If your Kaching setup is a three-tier “Buy 1 / Buy 2 / Buy 3” offer and maybe a gift, Volumo does that, with tiers suggested from your margin, a real-date countdown and an A/B test, and the discount applied by Shopify at checkout.
Switching
Recreate your tiers in Volumo first, as a Draft. Then, in one sitting: set the Volumo deal to Active, add the Volumo block where Kaching’s block was, turn off Kaching’s discount, and check a test order. Keep Kaching’s numbers from the week before to compare conversion.
Volumo by Centubo. Shows quantity breaks, buy X get Y, bundles and free gifts on your product pages, and applies the discount at checkout. Free during launch.

How does Kaching's pricing work?
Its plans are set by the additional revenue the app tracks for your store: Starter $14.99 a month up to $1,000, Scale $29.99 up to $5,000, Pro $59.99 up to $10,000 (App Store listing, November 14, 2026). Each has a 7-day trial and yearly options.
Does Volumo do mix and match?
Partly. A quantity breaks deal in Volumo can count items of every product in the deal together (1 serum + 2 creams reaches the 3-item tier). It doesn't have build-a-box or sectioned mix-and-match bundles.
