Key takeaways

  • Run one small SaaS loop (build → grow → sell) before the main bet to secure the ‘what works’ template
  • Pick a place where demand is pre-validated: Shopify App Store search volume is itself proven need
  • Funnel distribution into in-platform SEO (ASO): weave real search keywords into app name/description to rank

The pain point, and how they found it

Hundreds of thousands of Shopify merchants share one obsession: raising average order value (AOV). Acquiring new customers via ads is expensive, but getting an existing buyer to add ‘one more’ or buy ‘as a set’ is far cheaper. Yet most store owners can’t code and can’t build bundles or upsells themselves. Erikas attacked that universal need — ‘lift the number merchants want most (AOV), no code, instantly.’ The pain was easy to locate: the very volume of ‘bundle’ and ‘upsell’ searches inside the Shopify App Store was pre-validated demand.

Background & product

Kaching Appz is a portfolio of Shopify apps built to raise merchants’ average order value. The flagship is the bundling app ‘Kaching Bundle Quantity Breaks,’ which lets merchants set volume discounts, product sets, and quantity breaks with no code. Around it sits a family of sibling apps — Post Purchase Upsell, POP Discount Upsell, Cart Drawer AI Upsell, Subscriptions — each laser-focused on the single job of lifting the value of the cart.

It was built by Lithuania’s Erikas Mališauskas, a UI/UX designer since 2011 who freelanced building Shopify sites from 2016. His co-founder (CTO) is Donatas Stundys. Erikas spent from 2018 trying and failing at his own products before reaching his first real success in 2021. Notably, before the big breakout he grew a different Shopify app to $6.5k MRR and sold it for $250k — then went all-in on Kaching with that playbook in hand.

The growth engine, remarkably, ran on zero ad spend. It scaled purely on Shopify App Store organic (ASO — in-store search optimization) plus a compounding base of reviews. Early on he had clients and friends install the apps for free to manufacture installs and reviews, push up the rankings, and kick off a snowball of organic traffic.

The result: $4.3M revenue in full-year 2024 (+$3.4M YoY), then a 10× run from $100k to $1M MRR in about a year, reaching ~$1M/month at 90%+ gross margin. More than 100,000 merchants have installed the apps, generating over $1.7B in additional revenue cumulatively. With a small team and no funding, it’s a model case of stacking a high-margin SaaS on top of the giant Shopify platform (the team has since grown to about 40 people, and full-year 2025 revenue reached roughly $4.5M).

Kaching Appz growth channels and tech stack

How it was built

  1. Run one small SaaS cycle before the real bet — grow another Shopify app to $6.5k MRR and sell it for $250k, learning build-grow-sell hands on
  2. Pick a place where demand is already proven: search volume inside the Shopify App Store is validated need
  3. Build a single-purpose app focused entirely on raising average order value (the flagship sets up bundles and quantity breaks with no code)
  4. Don't stop at one app — cover the surface with siblings: Post Purchase Upsell, POP Discount Upsell, Cart Drawer AI Upsell and Subscriptions, where a shared customer and technical base keeps marginal cost low from the second app on
  5. Let Shopify carry payments, delivery, credit and international billing, keeping development and operations thin (the foundation of 90%+ gross margin)

How it got users

  1. Consolidate distribution into in-platform SEO (ASO) — weave the keywords merchants actually type ('bundle', 'quantity breaks', 'upsell') into the app name and description to rank inside store search
  2. Break the review chicken-and-egg by hand — early on, have clients and friends install the app for free, stacking installs and reviews manually to push the ranking up
  3. Once ranked, let the algorithm amplify the loop of rank to organic traffic to more reviews to higher rank — only the first push is manual
  4. Use the portfolio to occupy the search surface for related keywords with your own apps, cutting leakage while stacking LTV as one store runs several
  5. Build the reason not to churn into the product — make customers more additional profit than the subscription costs (100K merchants generated $1.7B in incremental sales)
Early ad spend
$0 — no external advertising at all, only organic search inside the Shopify App Store and accumulated reviews

The repeatable playbook

  1. 1Run one small SaaS loop (build → grow → sell) before the main bet to secure the ‘what works’ template
  2. 2Pick a place where demand is pre-validated: Shopify App Store search volume is itself proven need
  3. 3Funnel distribution into in-platform SEO (ASO): weave real search keywords into app name/description to rank
  4. 4Crack the review chicken-and-egg by hand: seed reviews via free installs early to start the ranking snowball
  5. 5Take the surface with a portfolio, not one app: own related keywords and cross-install to multiply LTV
  6. 6Embed the reason not to churn: make customers earn ‘extra profit’ exceeding the fee — value-linked retention
  7. 7Let Shopify handle payments/delivery/billing; keep dev and ops thin to hold 90%+ gross margin

Channels they actually used

The hard parts

Behind the headline ‘$1M/month at 90%+ margin,’ Erikas spent from 2018 trying and missing at his own products, reaching his first success only in 2021. Even the $250k sale of an earlier app mattered less for the money than for the experience of completing a ‘build-small-and-sell’ loop and acquiring the template. Those years of failure weren’t waste — they were the investment that bought the winning pattern.

Updates since publication

  1. Sep 11, 2026

    Full-year 2025 revenue reached ~$4.5M (up slightly from $4.3M in 2024), and the founder publicly confirmed reaching $1M monthly recurring revenue in December 2025 (consistent with the previously reported milestone). The team has grown to about 40 people, and an enterprise push began in 2026, landing its first enterprise client at $2,000/month on a 12-month contract. Confirmed via a new Starter Story interview.

Deep dive

【Deep dive】$1M/month at 90%+ margin with zero ad spend and a small team. Kaching demonstrates an unglamorous, reproducible template: ‘in-platform SEO × portfolio × value-linked stickiness.’ Let’s break it down in order.

Buy the playbook through an apprenticeship: 3 years of failure → a $250k exit → all-in. From 2018 Erikas tried and missed at his own products. Before the breakout he grew a different Shopify app to $6.5k MRR and sold it for $250k. What matters isn’t the figure but that he ran a full SaaS loop — build small, grow, sell — and walked away holding the template of ‘what works.’ Most indie devs rush to land a first hit; he first completed a lap, secured the winning pattern, then went all-in on Kaching. Those three years of failure weren’t waste — they were the price of the playbook.

Distribution funneled entirely into ‘in-platform SEO’ (what ‘zero ad spend’ really means). Kaching’s acquisition isn’t external ads — it’s all-in on organic search inside the Shopify App Store. The key is ASO: weaving the keywords merchants actually type (‘bundle,’ ‘quantity breaks,’ ‘upsell’) into the app name and description to rank in in-store search. Unlike Google SEO on a new domain, the App Store is a pond already stocked with high-intent store owners, so search intent maps directly to the product and CAC approaches zero. ‘Zero ad spend’ isn’t austerity — it’s the rational result of picking the highest-ROI channel.

The review snowball: kick off the cold-start ‘by hand.’ App Store ranking is driven by review count and rating, but a new app faces the chicken-and-egg of zero reviews. Erikas split it the gritty way: early on he had clients and friends install the apps for free, manually stacking installs and reviews to push up the rankings. Once you crest into the top, a virtuous loop spins — top rank → organic installs → more reviews → higher rank. Do only the first push by hand and let the platform’s algorithm amplify the rest — that’s how you start a snowball on a zero budget.

Take the surface with a portfolio, not a single app. Kaching doesn’t sell one single-feature app — it blankets the ‘raise AOV’ space with several: Bundles, Post Purchase Upsell, POP Discount Upsell, Cart Drawer AI Upsell, Subscriptions. Two aims. First, fill the App Store’s related-keyword results with your own apps so you lose fewer searchers (owning the search surface). Second, get one store to run multiple apps, multiplying LTV (cross-install). Because the same customer base and tech base are reused, the marginal cost of each additional app is low — itself a driver of the 90%+ margin.

Build stickiness through ‘value linkage’: embed the reason not to churn. Installing Kaching’s apps actually raises a merchant’s AOV — their revenue. The 100K+ stores using them have generated over $1.7B in additional revenue cumulatively. That is the heart of stickiness: as long as the extra profit the app generates exceeds its fee, the merchant has no reason to cancel. Billed as a ‘profit-generating machine’ rather than a cost, price sensitivity drops and churn is structurally low. Instead of fighting churn with UI retention tricks, Kaching bakes it in through the outcome — ‘the customer makes money.’

Why 90%+ margin works with a small, unfunded team. Payments, delivery, billing, fraud, and international tax are all handled by Shopify, so the team focuses on the app itself. Distribution is internalized via App Store SEO with no external ad cost. Sharing tech and customer base across the portfolio keeps operations thin. The result: most revenue falls to profit (90%+ gross margin). Stack a near-zero-CAC, thin-ops, hard-to-cancel SaaS on top of ‘someone else’s giant traffic’ (Shopify) — that is Kaching’s design philosophy, and the most refined form of a platform-piggyback strategy (by 2025 the team had grown to about 40 people and an enterprise push had begun in 2026, though the bootstrapped, organic-growth economics at its core haven’t changed).
