Both apps cap plans by added revenue, but each counts it its own way. Ours is counted when the order is completed, and the trigger product in a frequently bought together offer isn't counted. Outgrow a plan and you move up automatically. Paid plans have a 14-day free trial and a 30-day money-back guarantee. Kaching's trial is 7 days. All 8 plans are on our Upsell pricing page.
Kaching's price advantage is real. Every Kaching plan includes unlimited bundle deals, multiple layouts and live chat support.
Winner: Essential Upsell & Cross Sell stores with up to $500 of added revenue a month, or stores that want a free start, because it's free up to $100 and $9.99 up to $500, while Kaching starts at $14.99. Above $500, Kaching Bundles is the cheaper app at every tier.
Which app has the offers and placements you need?
Essential Upsell & Cross Sell puts offers on the product page, the cart page, after payment (post-purchase) and in pop-ups on Shopify. Kaching Bundles names the product page, checkout and Shopify POS, and puts its depth into bundle types and quantity breaks. Pick by the offer you want to run.
Our product and cart offers come as cross-sell, add-on or frequently bought together. Triggers can be a product, a collection or cart value, with exclusions. Cart page offers start on the $19.99 plan, and showing offers inside a cart drawer also needs Essential Cart Drawer. Our cart upsell page has the details.
Post-purchase is the clearest gap. Our offer shows after payment and before the thank-you page, and accepted items are added to the original order and charged automatically. If the customer declines, a second offer or a downsell can follow. Kaching's listing doesn't show post-purchase offers. Our post-purchase upsell page and guide to post-purchase upsells on Shopify cover setup.
One limit to know: Shopify, not the app, decides when the post-purchase page shows. It doesn't show for some payment methods (Klarna, Affirm, Afterpay, Sezzle, Apple Pay, Google Pay, Shop Pay express, cash on delivery, bank transfers), orders under $0.50, or orders not in your store's default currency. This affects every post-purchase upsell app. Only one post-purchase app can be active at a time.
Winner: Essential Upsell & Cross Sell stores that want post-purchase offers, because Kaching's listing doesn't show post-purchase offers, and ours add accepted items to the original order with a second offer and a downsell.
What do the free Essential companion apps add?
Essential Upsell & Cross Sell is one of 14 Essential apps for Shopify, and every app has a free plan. Three companions fill gaps in the Upsell listing: Essential CRO Split AB Testing, Essential Checkout and Essential Cart Drawer. They're separate apps, and you install each one on its own.
Essential Checkout: free, Built for Shopify. Thank-you page offers and banners, a free shipping bar upsell inside checkout, checkout validation and discounts. Details on the Checkout page. On the App Store it's listed as "Esse Checkout Customize Upsell".
Essential CRO Split AB Testing: free, Built for Shopify. It split-tests page templates and themes with zero page flicker. It doesn't test individual upsell offers. See A/B Testing.
Essential Cart Drawer: Built for Shopify, with cart upsells, free shipping and free gift tiers, and a progress bar. The free plan covers 30 orders a month, and paid plans start at $8.99 a month. See Cart Drawer.
Winner: Essential Upsell & Cross Sell stores that want thank-you page offers, template tests or a cart drawer without another paid app up front, because the companion apps are free to start, though offer-level A/B testing isn't part of our suite and Kaching has it built in.
Which app has better support?
Both apps publish comparable support on Shopify, so it's a tie. Our site says Essential Upsell & Cross Sell has real humans available 24/7, and the homepage says the team usually replies in under 10 minutes. Kaching Bundles lists live chat support on all plans. We can't compare response times.
Tie: on their listings and sites both list live support, and we have no data to rank their response times.
How do the offers look in your store?
Both apps carry the Built for Shopify badge, so both meet Shopify's bar for performance, design and integration. Essential Upsell & Cross Sell installs as a theme app embed with no code. Kaching Bundles lists more layout and styling control, including custom CSS and HTML.
Our post-purchase offer inherits your checkout styling, and Shopify limits button customization there. Cart and pop-up offers have adjustable text, layout and colors, and the listing tags include drag-and-drop editor and mobile responsive. Kaching lists multiple layouts, endless customization, a drag-and-drop editor and an AI bundle builder.
Winner: Kaching Bundles bundle layouts and custom styling, because its listing names more layout and code-level control than ours does.
Which app supports more languages?
Essential Upsell & Cross Sell supports 20 languages on Shopify, including Japanese, Korean, Thai, Polish, Czech, Danish, Finnish, Norwegian and both Chinese scripts. Kaching Bundles supports nine: English, French, German, Spanish, Italian, Dutch, Swedish, Turkish and Brazilian Portuguese. If you sell outside those nine, Essential covers more.
Winner: Essential Upsell & Cross Sell stores selling in more than nine languages, because 20 languages against 9.

Its listing names fixed bundles, multipacks, mix-and-match, variant bundles, build a box, subscription boxes and quantity breaks. It also lists A/B testing, Shopify POS and 6,685 reviews, and it costs less from just over $500 of added revenue a month.
