K: Quantity Breaks vs Qikify Volume Discounts: which quantity break app fits your Shopify store?

Quantity breaks are one of the oldest tricks in retail: buy two and save 10 percent, buy four and save 20. On Shopify, this category is crowded with a few heavily reviewed apps, so most merchants never scroll past the first page of search results. K: Quantity Breaks by Kaktus and Qikify Volume Discounts live further down that list. Both are small, both are well rated, and both do the core job: show a tiered discount table on the product page and apply the right price at checkout. Where they split is the price model, the range of offers, and how long each one has been around.

Everything on this page was checked on October 22, 2026 against the two App Store listings, the Kaktus product, pricing and documentation pages, and Qikify's launch article and help center. When a feature does not appear in those sources, we say it is not listed instead of guessing.

Who is behind each app

K: Quantity Breaks, Discounts (Kaktus)

Kaktus is a small studio that publishes several conversion widgets for Shopify, including a sales pop up app, and also sells its tools for WooCommerce, Wix, Squarespace, Webflow and a dozen other platforms. The quantity break app went live on the Shopify App Store on May 12, 2022. It holds a 4.8 rating from about 40 reviews. The listing pitches it for "flexible tiered pricing and volume discounts" and mentions B2B, wholesale and members pricing. The admin is available in English only, and the app does not carry the Built for Shopify badge.

Qikify Volume Discounts Bundle

Qikify is a better known Shopify publisher with a family of apps: upsell and free gift, sticky cart, checkout customizer and more. Its volume discount app is young. It launched on September 12, 2025 and gathered roughly 100 reviews with a 5.0 average in about a year. It carries the Built for Shopify badge, which means Shopify reviewed it against its performance and design requirements. The admin is translated into nine languages, including French, German, Spanish, Italian, Japanese and Portuguese.

Pricing: the gap that decides most cases

Kaktus charges by monthly orders

On the App Store listing, the free tier only applies to development stores. A live store picks one of two paid plans, each with a 7 day free trial:

• Growth at $9.99 per month, for up to 9 Shopify store orders per month
• Growth 2 at $19.99 per month, for up to 100 Shopify store orders per month

Both plans include the same features. The Kaktus website shows a longer usage table that keeps climbing past 100 orders: $29.99 for 101 to 300 orders, up to $69.99 for more than 1,001 orders a month. The App Store listing does not show those higher tiers, so if your store is above 100 orders a month, ask Kaktus support which price applies before you install.

Qikify is free

The listing shows a single price: Free. Qikify's launch article goes further, under a heading that reads "All features, completely free", and says there are no limitations, hidden costs or feature restrictions. We found no paid plan, order cap or offer cap in any source. One caution: free apps sometimes add paid plans later, and Qikify's other apps do have paid tiers. Check the listing before you commit, and again every few months.

What that means in dollars

A store doing 80 orders a month pays $19.99 a month with Kaktus, about $240 a year, and nothing with Qikify. For a small store, that difference can be a meaningful share of the extra margin a quantity break is meant to bring in. Our piece on free vs paid Shopify apps explains when paying still makes sense.

Offer types

Kaktus: one job, done simply

Kaktus focuses on tiers for a single product. You set as many tiers as you want (the listing says "Unlimited Pricing Tiers"), choose a percentage or a fixed amount off, and pick a trigger: specific products, any product, or a specific collection. A countdown timer option helps run limited time offers, and the listing mentions member only and VIP pricing tiers. BOGO, free gifts, mix and match bundles and subscription products are not listed on its App Store page or its product page.

Qikify: quantity breaks plus a bundle toolkit

Qikify covers the same single product quantity breaks, then adds several other offer types documented in its help center:

• Multibuy or mix and match combos, with a percentage off or a fixed total price
• Multipacks and sample packs
• Buy X Get Y and free gifts per tier
• Free shipping and cart discounts for bulk orders
• A wholesale pricing offer that shows several variants and quantities in one view
• Volume tiers on subscription products, as long as you already run a subscription app

If all you want is "buy more of this item, pay less", both apps do it. If you expect to test bundles or gifts later, Qikify saves you a second install. For pricing logic, see our guide to bundle pricing without killing margin.

Building an offer

Kaktus setup

The Kaktus documentation describes a short flow: create a volume offer, choose the trigger products, add the quantity and discount options, add conditions, then publish. The widget appears once you enable the app embed in the theme editor. The product page says the discount "will be applied on the checkout page". The listing also shows a Sidekick integration.

Qikify setup

Qikify lets you build an offer by hand or type a prompt describing it to an AI assistant, which then drafts the offer. Smart presets speed up common setups. Campaigns accept start and end dates, which is handy for a seasonal push like the ones in our flash sales guide. The listing says discounts are "native to Shopify discount", and the help center documents a Sidekick integration too.

Storefront design

Kaktus ships three widget templates named Default, Modern and The Sun. You can adjust colors, font sizes and styles, edit every string in a Translation tab, and set the widget position or custom cart selectors in settings.

Qikify describes discount badges, savings calculators and progress indicators, with control over colors, fonts, layout and position, plus a custom CSS field. One September 2026 review notes that some options could not be edited in the offer settings and had to be changed in theme code, so plan a few minutes for fine tuning if your design is strict.

Analytics and tracking

This is where Kaktus clearly leads. Its dashboard reports popup views, add to cart events, conversions, conversion rate and revenue for each offer. Settings accept Facebook, Pinterest, Snapchat and Google Analytics IDs, IP exclusions and email notifications. If you run paid traffic and want to read offer performance without opening another tool, that is useful.

Qikify's launch article mentions "analytics integration", but neither the listing nor the help center previews describe what the reports contain. We could not confirm the depth of its reporting from public sources.

Integrations and compatibility

Qikify lists Checkout, Shopify Admin, POS, PageFly, Foxify, GemPages and Product options under "Works with", and says it supports agentic commerce. That matters if you sell in a physical shop too, or if your product pages are built with a page builder.

Kaktus lists Checkout and Sidekick. POS, page builders and Shopify Markets are not listed. Neither app states in its public sources how its discounts combine with other discount codes, so test a cart with your usual promo code before going live.

Support and reviews

Kaktus reviews from 2022 and 2023 praise fast, helpful support, and the most recent review, from September 2026, is positive. One 1 star review from October 2024 complains about being charged for months without using the app. Kaktus replied that charges go through Shopify billing and must be approved by the store owner. The general lesson: uninstall any app you stop using, since that ends its Shopify charge.

Qikify reviews from mid and late 2026 mention support reps by name, quick bug fixes and features added on request. The rating is a near perfect 5.0, but the track record is about one year long, against more than four years for Kaktus.

Three store profiles

A single product supplement brand at 60 orders a month

The goal is "buy 2, save 10 percent; buy 3, save 15 percent" on one hero product. Both apps handle it. Qikify costs nothing, which leaves budget for ads. Kaktus at $19.99 a month earns its place only if you will actually use its per offer conversion and revenue dashboard and its pixel settings to steer campaigns.

A craft supplies wholesaler with many variants and a physical counter

This store needs price tiers on dozens of colors and sizes, plus discounts at the counter. Qikify's wholesale pricing offer shows several variants and quantities in one view, and POS appears in its compatibility list. Kaktus mentions wholesale pricing in its listing but does not describe a variant grid or POS support.

A merchant running Shopify and a WooCommerce store side by side

Kaktus sells the same family of widgets on WooCommerce, Wix, Squarespace and other platforms. If you want one vendor and one way of working across two storefronts, that is a real reason to pick it, as long as your Shopify volume fits its order based pricing.

Switching from one app to the other

From Kaktus to Qikify

1. Write down every active tier: products, quantities, discount values and schedules.
2. Install Qikify and rebuild the offers, by hand or with the AI prompt.
3. Turn off the Kaktus app embed in the theme editor so two tables do not stack on the product page.
4. Uninstall Kaktus, then check Shopify billing to confirm the charge has stopped.
5. Place a test order with several quantities and with your usual discount code.

From Qikify to Kaktus

You would do this if Qikify introduced paid plans that no longer suit you, or if you want Kaktus's conversion reporting. Rebuild the tiers in Kaktus, enable its app embed, then remove Qikify. After uninstalling, look through the Discounts section of your Shopify admin and delete any discount left behind so old tiers do not keep applying.

Whichever app you keep, run only one quantity break app at a time. Two widgets on the same page confuse shoppers and slow the page down, as explained in our article on app bloat and site speed. If you are also weighing the two best known apps in this space, our Kaching Bundles vs Wide Bundles comparison covers them.
