The main difference: how you pay
Kaching's plans are capped by the extra revenue the app brings in. ZS Bundles is capped by the number of orders that contain a bundle. If your bundles are high-priced (furniture, electronics, premium skincare), a revenue cap fills up fast and an order cap is usually cheaper. If you sell many small, low-priced bundles, compare both with your own numbers.
When Kaching is the better choice
- You want an app with a long track record and thousands of reviews.
- The Built for Shopify badge matters to you or your client.
- You mainly need quantity breaks with a lot of layout options.
When ZS Bundles is the better choice
- You want a real free plan on a live store, not only a trial.
- Your average bundle is expensive, so paying per order beats paying per revenue.
- You need mix and match boxes, fixed sets and Buy X Get Y in one app, with offers limited to signed-in, VIP or wholesale customers.
- Your team works in German, Spanish, French or another of the 9 admin languages.
How the discount is applied
In ZS Bundles the bundle price is calculated by Shopify at checkout and checked again whenever the cart changes. There is no discount code to share or leak, and removing an item from a bundle removes its discount.
