20 Best Shopify Apps to Increase Sales in 2025
If you have a Shopify store with great products, a verified product-market fit, and even launched ads, it still might not guarantee sales. A lot of Shopify merchants reach a point where new traffic costs more than it earns, and even flash sales and discounts don’t have any impact on your shop’s performance.
Most store owners believe that larger discounts or lower prices would solve the problem. Unfortunately, it will only bring in new problems. Before you make such drastic changes, you should analyze how your Shopify store actually works. In other words, you do need a systematic approach to this process.
There’s no single magic app that can grow sales alone. But a smart ecosystem, where each app covers a key stage of the customer journey, can. When you combine apps that help attract quality traffic, engage visitors into conversion, then upsell, and retain for future purchases, that’s when your store starts to scale systematically.
In this guide, we’ve collected the best Shopify apps to increase sales — free and paid — and show how they work together as one ecosystem.
How to Choose Shopify Apps to Boost Sales
The Shopify App Store is a total “kid in a candy store” problem, right? You just want everything. Every app looks like the one magic fix your store is missing. You see another shiny new app and think, “This is it!”
But before you click “install,” just...stop. Ask yourself: What's actually broken?
The best stores aren't bloated with 50 different Shopify plugins. They use a handful of good apps, and every single one has a job. Are you bleeding traffic? Is your AOV stuck in a rut? Still sending follow-ups by hand? Find an app for that.
We've organized the best Shopify apps to boost sales by each step of the customer journey. We'll cover everything from getting found (SEO) to keeping them around (loyalty).

Summing up
So, what's the big takeaway? There's no single app that will magically fix your sales. The real secret is to stop being the "kid in a candy store" and start thinking like a surgeon. Don't just go on an installing spree. Take a hard look at your store and find your one biggest bottleneck.
Are you getting zero traffic? Start with an Attract app (like a good SEO tool).
Are visitors bouncing? Add an Engage app (like for reviews).
Are carts abandoned? That's a Convert or Retain problem (get an upsell or email app).
Are you just guessing? Get an Optimize app (like heatmaps) and find the problem.
Find your biggest problem, whether it's traffic, trust, or follow-ups. Then find the one app from this list that solves it. Install it, set it up, and make it work. Then move to the next. That's it. That's how you build a truly great app stack.
