Kaching Bundles app: Bundle Deals for Shopify Stores That Sell Several Units per Order

What Kaching Bundles Does for Your Store, and What It Doesn't

Kaching Appz describes the app, on its App Store listing, as a way to “increase your average order value with offering bundles, gifts, and applying volume discounts.” Its deal editor offers six templates. Kaching's help center describes three of them — quantity breaks for the same product, buy X get Y, and complete the bundle, which it calls Bundle Upsell — and those three are the ones our test ran. The other three are quantity breaks for different products, subscription and progressive gifts.

Every deal we ran was a Shopify discount on products you already sell. None of the three created a bundle product: in our test on a development store on September 17, 2026, each deal's discount landed on the product's own cart lines, and stock came off the product's own variant.

The widget loads only while the Kaching Bundles app embed is on in your theme: Kaching's help center says turning the embed off removes all widget and bundle logic, and adding ?kaching=off to a product page URL does the same for one visit. In our test on a development store, installing the app didn't switch the embed on.

Past a standard online store, four setups decide whether Kaching fits:

Kaching column: App Store listing, kachingappz.com and the help center's sitemap, read September 17, 2026. Shopify column: Shopify changelog and shopify.dev, read September 17, 2026. None of the four was tested.

Ask Kaching in writing before relying on bundle prices at the counter, for wholesale buyers or on subscriptions.

Before paying for any app, check whether one of Shopify's own routes already covers the job:

Shopify Help Center and shopify.dev, read September 17, 2026.

Its listing showed a 5.0 rating across 5,900+ reviews and the Built for Shopify badge on September 17, 2026, and gives August 11, 2022 as its launch date; what that badge certifies is covered in our Built for Shopify guide.

Installing it grants access to data including customer email and browsing data and the store owner's name, email address, phone number and physical address, and edit access including products, orders from the last 60 days, discounts, cart transforms, inventory and Markets settings, per the listing's data-access section read September 17, 2026 — what a Shopify app can see of your customers.

Where Kaching Bundles Earns Its Place

The listing files the app under Product bundles and Upsell and cross-sell; underneath both is one job — more units, or more products, in each order. Three store situations decide how a deal behaves.

One Best-Seller Customers Buy More Than One Of

The case the app is built around: a product people already buy two or three of, and a “buy 2, save” offer on its page. The deal shows as bars — one unit at full price, two or three at a lower price each:

Zoom

1. Switch on the Kaching Bundles app embed in your live theme and save.
2. Create a quantity break with a price for one, two and three units — ours was $600, two for $960, three for $1,350.
3. Before publishing, set Products to the item the deal is for and fill in the discount name.

The same editor carries the other forms of the move. In our test on a development store, complete the bundle put two different products on two separately discounted lines with no parent bundle product, and buy one, get one showed the second unit as a free line at checkout.

Where it goes wrong is the two defaults that step three changes: a new deal starts on All products, and with the discount name left blank, cart and checkout show the bar's title — “Duo” in our development-store test. If the same product already carries your own discount or sells in a second currency, the next two scenarios apply.

Your Store Already Runs Its Own Sales and Codes

The case: automatic discounts or codes already touch the products you want a deal on. Kaching's help center says its bundle discounts count as product discounts and that “we do not have control over how Shopify combines discounts,” and Shopify states what happens then:

On September 17, 2026, our test on a development store saw exactly that: a native 10% discount never joined the two-for-$960 deal, while a 5% order code applied on top only once it was set to combine with product discounts.

1. List the automatic discounts and codes that touch the deal's products.
2. Decide which should win on those items, and change the other if it shouldn't apply there.
3. Set each store-wide code you keep to combine with product discounts — Kaching's help center describes creating it as an order discount that combines with product discounts.

Where it stops: combining two product discounts on one line is for Shopify Plus stores only, through matching tags, and the Kaching discount's settings open only inside the app, which showed no combination options — so whether a Plus store can tag it, we couldn't check. In our development-store test all three deals shared one automatic discount entry, one of the 25 active automatic discounts Shopify allows a store.

How Shopify's combination rules work across all discount types is covered in our guide to combining and stacking discounts.

You Sell in More Than One Currency

The case: Shopify Markets sells your store in a second currency with its own product prices, and your deal uses a fixed price such as two for $960.

Kaching's article on market-specific bundles promises “automatic currency adjustments” in its summary, but its body tells you to duplicate the bundle, change what you need, such as the price, and assign it to a different market. Follow the body:

1. Preview the product page in each market currency.
2. Compare the saving shown with the one you advertise.
3. Where they differ, duplicate the deal for that market with its own price.

In our development-store test nothing flagged the smaller saving: the cart and checkout simply matched the widget's converted price. How Shopify sets product prices per market is covered in our Shopify Markets guide.

What the App Actually Did on Our Test Store

Key takeaway

The test ran from September 17, 2026, on a Shopify development store on the app's free plan for development stores, selling in US and Canadian dollars, with three products at $600, $749.95 and $1,025, 50 units each, two orders through a test payment gateway and the revenue count read again on September 19, 42 hours after them. The widget looked the same in a preview of Shopify's Horizon theme as on the store's published theme.

Two things showed before any deal existed, and both bear on the bill. On a development store the app skipped its plan screen and carried a banner on every page: “This app is free for development stores. When your store goes live, all bundle deals will be hidden until you choose a plan and approve subscription.”

And its Plan management screen listed eight paid plans, not the listing's three, with an “Overage price, per $100 added” column that appeared only in the annual view — which plan fits works through both.

Publishing the first deal created a single automatic discount in Shopify's Discounts list, “Kaching Bundles - Bundle”; the two later deals joined that entry instead of adding their own, and the entry opens inside the app, so a deal can't be edited from Shopify's discount page.

Every result below was read in Shopify's own admin and in the cart, checkout and order data behind it, not taken from the app's dashboard, which was itself under test:

What Kaching Bundles did on our test store

What we set up or broke	What happened	What it means for you
Quantity break on the $600 product: one at full price, two for $960, three for $1,350	Two units became one cart line with $240 off, named “Duo” after the bar because the discount-name field was blank; stock went 50 → 48 from the product's own variant, and back to 50 after a refund with restock	Name the discount yourself; stock and returns run as for any product
Complete the bundle: the $749.95 product at 10% off with the $1,025 product at 15% off	Two lines, each with its own discount — $74.99 and $153.75 — and no parent bundle product; order total $1,546.21	A bundle of different products is two discounted lines, not one bundle item
Buy one, get one free on the $1,025 product	Two lines of the same product, the second at $0 and marked free at checkout; no order placed	The free unit shows as its own line in cart and checkout
A native automatic 10% discount on the same product, with combining off and then on	Only the deal's $240 applied, both times	A deal and another product discount won't both apply — pick the winner
A 5% order code set not to combine	Checkout refused it: “KBTEST5 couldn't be used with your existing discounts”	A code not set to combine fails on a cart with a deal
The same code, set to combine with product discounts	Both applied, the 5% taken from the discounted $960, for $912	The setup that works for a store-wide code
The Canadian market, in Canadian dollars	Product at CA$810, the two-for deal at CA$1,362.79 — the fixed $960 converted; the saving shown fell from 20% to 16%, and cart and checkout matched	Check fixed prices in every market currency
Revenue count, read 42 hours after two test orders	$0 in the dashboard, Analytics and plan screen, against $360 by the help center's formula; Analytics counted 5 add-to-carts and 0 bundle orders	The number your plan rides on didn't move in our test, so we couldn't check it
Uninstall, then reinstall inside Kaching's 48-hour restore window	Uninstalling removed the discount and the widget; the reinstall brought back all three deals with their statistics, but in the ten minutes we watched, not the discount or the storefront widget	“Deals restored” is not “deals live” — check a product page
Final uninstall	The app embed stayed switched on in both themes, empty	Switch the embed off in the theme editor yourself

One test on a Shopify development store, September 17–19, 2026: two orders through a test payment gateway; the buy-one-get-one deal was checked in cart and checkout only.

The count is the result to weigh before you buy, because Kaching's price is tied to it. A refund with restock put stock back and left the count at $0, so the test can't show whether refunds lower it.

Zoom

Kaching Appz later gave us its own account of two results — the $0 count and what the reinstall brought back; its answers follow this section, and they don't change what the test measured.

The test did not cover billing on a live store, Shopify POS, subscriptions, headless storefronts, themes beyond the store's own and a Horizon preview, any effect on conversion, or the other three of the six deal templates.

Which Plan Fits Your Deal Volume

The limit isn't your sales, your bundle revenue or your order count. Kaching's help center defines “additional revenue” with an example:

Its Flex Billing article, last updated July 23, 2026, repeats the $6 and adds that only multi-item orders count and that the count resets on the first of each month. By that formula, two of a $600 product sold for $960 count $360; in our test on a development store the count read $0. Nor is the count proof that a deal earned anything, since a shopper might have bought two anyway — how to measure lift with a holdout is covered in our cross-sell guide.

The listing says all charges are billed in US dollars and recurring and usage-based charges every 30 days; Kaching's annual-plans FAQ says an annual plan is billed once, upfront. Every paid plan carries the same features — the listing names unlimited bundle deals on each — so one number sets your plan, per Kaching Bundles' App Store listing:

Development stores to Pro: the App Store listing, read September 17, 2026. Growth to Enterprise: kachingappz.com/pricing, read September 17, 2026, and the Flex Billing (updated July 23, 2026) and annual-plans FAQ (updated June 9, 2026) help articles. Enterprise Plus: the Plan management screen in our install on a development store, September 17, 2026. All prices in US dollars.

The listing stops at Pro and links to “See all pricing options”; Kaching's pricing page and help center continue to Enterprise at $299 a month for over $50,000, and the plan screen in our install added Enterprise Plus from $2,000. Treat that in-app screen as your price list, and approve nothing on Shopify's confirmation screen that you haven't seen there.

On a development store the app is free, but its banner says deals are hidden once the store goes live until you choose a plan and approve the subscription, so if an agency builds your deals there, pick the plan before launch day. If you don't choose one after the trial, Kaching's Flex Billing article says “we'll automatically enroll you in Flex Billing.”

What happens past a limit depends on which of Kaching's help articles you read:

Kaching Bundles Help Center, read September 17 and 19, 2026. Dates are each article's own last-updated date.

None of the three, as we read them, explains why they differ, so ask Kaching's support in writing which one applies to your billing before your deals near the limit. Kaching Appz told us on September 22, 2026, that the three rules cover different billing modes, which its help center didn't say as of that date.

Whichever applies, when an app raises the spending limit on a usage-based subscription, the merchant must approve the new pricing limit before it takes effect — Shopify's general rule, which doesn't say how Kaching runs Flex Billing.

If you are weighing another bundle app, its price may follow a different axis. The base matters as much as the axis. In Kaching's own example, a bundle of two $10 items sold for $16 counts $6, where an app counting bundle sales would count $16, so the same limit covers more sales under Kaching's count; which costs you less depends on how much of your revenue runs through deals.

How ten listings set their monthly price, as read on September 17, 2026 — an axis, not a ranking:

Set These Up Before a Deal Goes Live

Steps one to four come before your first deal, five to seven are about the bill, and eight is for the day you remove or reinstall the app:

The Bottom Line

What the app does, it did cleanly in our test on a development store: a quantity break became one cart line at the deal price, stock came off the product's own variant, no bundle products appeared in the catalog, and all three deals shared one automatic discount — one of the 25 active automatic discounts Shopify allows a store.

What it can't give you yet, as of September 2026, is a predictable bill. Three of Kaching's help articles disagree about what happens at a plan's limit, and the count the limit rides on read $0 on our development store, so the first real orders are where you learn what you will pay.
