EcommerceThere are more than 8,000 apps in the Shopify App Store, and most store owners I talk to have a dozen of them installed, quietly paying anywhere from $30 to $300 a month for tools they don't need. Or worse, tools that are dragging down store speed and conversion rate. At Mays Growth Partners I take the opposite approach: install fewer apps, but the right ones.
The premium Shopify apps worth paying for are Klaviyo (email and SMS), Loox (visual reviews and UGC), LiveRecover (human-powered cart recovery), Gorgias (customer support), Rebuy (AI upsells and personalization), Loop Returns (exchanges over refunds), and Smile.io (loyalty and referrals). You don't need 8,000 apps. You need about seven good ones and a strategy for using them.
I'll also answer a question I get constantly from newer store owners: should you build on Shopify or invest in a custom site? I work with a lot of ecommerce founders who don't have six figures to burn on a custom build, so this matters. My honest take is at the bottom.
Klaviyo is the highest-ROI app on this list, period. The average ecommerce store drives 20 to 30% of its revenue from email, yet most brands sit at 5% or less because they never set up their automations. The power is in the flows: abandoned cart, welcome series, post-purchase follow-ups, and win-back campaigns that run 24/7 once configured. A basic three-email abandoned-cart sequence alone can recover 10 to 15% of lost carts.
I can vouch for this personally. I used Klaviyo, alongside Loox, to scale my own brand, Smile Natural Products, and between the two of them I recovered roughly 17% of sales in recovered baskets, a number I corroborated through Google Analytics. There's a free tier to start, and it scales with your list. Non-negotiable for any serious store.
People don't trust brands, they trust other people. Loox collects photo and video reviews from real customers and displays them across product, home, and collection pages. For apparel and physical products it's massive: a real person using or wearing your product answers sizing, fit, and color questions before the customer even asks. Stores using it commonly see a 10 to 20% conversion lift on product pages, starting around $12.99 a month.
This one I lived firsthand. After seeing how effective Loox was for Smile Natural Products, I started incentivizing customers with small discounts in exchange for reviews, and it paid dividends. More UGC meant more social proof, which meant higher conversion, which fed right back into the recovered-basket revenue Klaviyo was capturing. The two apps compound each other.
Most abandoned-cart tools fire off a robotic text that gets ignored. LiveRecover uses real people texting your abandoned customers on your behalf. When a shopper bails because they're unsure about fit or fabric, a human can answer naturally and drop a personalized one-time discount to close the sale. It's free to install, and on the startup plan they take 15% of the revenue they generate, so you only pay when they actually make you money. Very low risk.
Gorgias centralizes every customer message, from email to Instagram DMs, Facebook, and on-site live chat, into one dashboard, with AI agents that can handle up to roughly 60% of repetitive "where is my order?" questions automatically. Faster, more organized support lowers refund and chargeback rates while lifting repeat-customer rates. Pricing starts around $10 a month and scales with ticket volume. Most useful once you're consistently above 100 orders a month.
Rebuy is an AI-powered personalization engine that touches every step of the shopping journey. Its smart cart surfaces genuinely relevant recommendations (add a hoodie, it suggests the matching joggers), and it runs in-cart, checkout, and post-purchase upsells while the buyer is still in buying mode. Reported average-order-value lifts land in the 10 to 30% range. There's a free tier, with the full feature set unlocking around $25 a month. If you're doing $20K or more a month, it typically pays for itself within the first 30 days on post-purchase upsells alone.
Online apparel return rates run 30 to 40%, which is potentially half your sales walking back out the door. Loop flips returns into exchanges: offer a different size plus a little bonus credit and you keep the revenue in your ecosystem instead of issuing a refund. Brands using it see 40 to 50% of returns convert into exchanges. There's a free tier, with the essential plan around $155 a month. A no-brainer once you're doing real volume.
It costs about five times more to acquire a new customer than to keep an existing one, and returning customers spend more, return less, and refer friends. Smile.io layers points, VIP tiers, and referral campaigns directly inside Shopify: early access to drops, rewards for referrals, and so on. This kind of loyalty engine helped brands like Gymshark build a cult following. It's not a day-one install, you need a customer base first, but it becomes important as you scale, and only if you actually deliver on the perks you promise.
A lot of the store owners I work with don't have a big budget for a custom build, so this is where I spend real time advising. Here's the trade-off.
It's fast to launch, predictable in cost, and effectively maintenance-free on the infrastructure side. Hosting, security, PCI compliance, and uptime are handled for you. The real superpower is the app ecosystem above: Klaviyo, Loox, Rebuy, Gorgias, and the rest plug in within minutes, so a lean brand can run an enterprise-grade stack without a developer on payroll. For most owners without a large budget, that's the whole game.
You're renting flexibility. Deep customization can hit theme and platform limits, monthly app fees stack up if you're not disciplined, transaction fees apply unless you use Shopify Payments, and you don't truly own the platform. Every app you bolt on is also a potential hit to page speed if you're careless.
Total control over UX, performance, and unique features. No per-app subscription creep once it's built. You fully own the codebase and data. For a brand with genuinely unusual requirements or the scale to justify it, a custom build can become a competitive moat.
High upfront cost, longer time-to-launch, and ongoing responsibility for hosting, security, updates, and bug fixes. You either hire developers or keep a maintenance retainer indefinitely. For a store owner watching every dollar, that money is almost always better spent on inventory, ads, and the app stack above.
My take: if you don't have a large budget for a custom build, start on Shopify, install the seven apps above with intention, and reinvest the money you saved into growth.
In my own experience with Smile Natural Products, that lean stack, Loox and Klaviyo in particular, added an estimated 17% in recovered-basket revenue, which is exactly the kind of ROI a custom build rarely justifies early on. Graduate to custom only when the platform's limits are provably costing you more than a rebuild would. Still weighing platforms more broadly?

You don't need 8,000 apps. You need about seven good ones and a clear strategy for using them. Apps are just tools; the strategy behind them is what drives results. For lean ecommerce brands, Shopify plus a disciplined premium app stack beats an expensive custom build almost every time.

For store owners without a large budget, Shopify is almost always the better choice. It launches fast, has predictable costs, handles hosting and security for you, and its app ecosystem lets a lean brand run an enterprise-grade stack without a developer. A custom build offers total control and no app subscriptions but carries high upfront cost and ongoing maintenance, so it is usually only justified at scale or with unusual requirements.
A basic three-email abandoned-cart flow in Klaviyo can recover 10 to 15 percent of lost carts, and visual reviews from Loox commonly lift product-page conversion by 10 to 20 percent. In our own brand, Smile Natural Products, Klaviyo and Loox together added an estimated 17 percent in recovered-basket revenue.
Install Klaviyo first. It has the single highest ROI of any ecommerce app because the average store drives 20 to 30 percent of revenue from email, and its automated flows run in the background once set up. Add Loox next for reviews and social proof, then layer in scaling apps as your order volume grows.
Yes. Many store owners install a dozen or more apps, some of which quietly hurt page speed and conversion rate. The better approach is to run a small, intentional stack of high-ROI apps rather than bolting on every tool available.
