Direct Answer
- Use email apps to recover lost sales (Example: Klaviyo)
- Use upsell apps to increase order value (Example: ReConvert)
- Use review apps to build trust (Example: Judge.me)
- Use page builders to improve conversions (Example: PageFly)
- Use loyalty apps to bring customers back (Example: Smile.io)
These 5 types of apps directly increase revenue, not just traffic.
The Real Problem Most Shopify Stores Face
You install a few apps. Maybe even 10.
But sales don’t move.
You might be wondering… why does this happen?
Because most stores don’t use apps with a clear goal.
Shopify has over 8,000+ apps available (https://www.shopify.com/app-store), and it’s easy to pick the wrong ones.
This guide fixes that.
You’ll learn which apps actually impact revenue—and how to use them step by step.
Why Most Shopify Stores Don’t Increase Sales
Too Many Apps, No Strategy
People install random tools without knowing what problem they solve.
Result? More clutter, no growth.
Focus on Traffic, Not Conversion
More visitors don’t always mean more sales.
If your store doesn’t convert, traffic is wasted.
Ignoring Post-Purchase Opportunities
Most stores stop after checkout.
But upsells after purchase can increase order value by 10–15% (https://blogpros.com/shopify-integration-increase-sales/).
How Shopify Apps Actually Increase Sales
Let’s simplify this.
All high-performing stores focus on 4 levers:
1. Conversion
Turn visitors into buyers using better pages and trust signals.
2. AOV (Average Order Value)
Increase how much each customer spends using bundles and upsells.
3. Retention
Bring customers back through email and loyalty programs.
4. Recovery
Get lost sales back using abandoned cart emails.
Abandoned cart emails can recover 3–8% of sales (https://blogpros.com/shopify-integration-increase-sales/).
Best Shopify Apps by Use Case
Conversion Apps (Make More Visitors Buy)
Page Builders (PageFly)
You may ask… why not use Shopify’s default editor?
Because design directly affects how people trust your store.
Page builders let you create clean, high-converting layouts without coding.
Tools like PageFly help you build pages faster and test different layouts easily (https://pagefly.io/blogs/shopify/best-shopify-apps-to-increase-sales).
Review Apps (Judge.me, Loox)
Think of it like this.
Would you buy a product with no reviews?
Probably not.
Reviews act as social proof and reduce hesitation.
They can increase conversions by around 19% (https://beplusthemes.com/best-shopify-apps-for-2025-reviewed/).
Upsell & AOV Apps (Increase Order Value)
ReConvert (Post-purchase upsell)
Most stores ignore the thank-you page.
That’s a missed opportunity.
ReConvert lets you show offers right after checkout when the customer is most likely to buy again.
This can increase order value by 10–15% (https://blogpros.com/shopify-integration-increase-sales/).
Frequently Bought Together
You’ve seen this on Amazon.
It suggests related products so customers add more items to their cart.
This simple strategy increases revenue without needing more traffic.
Marketing & Recovery Apps
Klaviyo (Email + SMS)
Email is one of the highest ROI channels.
It helps you recover lost users and stay in touch with customers.
It can drive 25–50% of total revenue for many stores (https://beplusthemes.com/best-shopify-apps-for-2025-reviewed/).
Omnisend
If you are just starting, Omnisend is easier to use.
It provides ready-made flows so you can start quickly without much setup.
Retention & Loyalty Apps
Smile.io / Growave
Getting a new customer is expensive.
Keeping one is cheaper.
Loyalty programs reward repeat buyers and increase lifetime value.
About 75% of customers engage more when rewards are offered (https://blogpros.com/shopify-integration-increase-sales/).
All-in-One Apps (For Simplicity)
Vitals
Instead of installing many apps, you can use one tool.
Vitals combines reviews, upsells, and urgency features in one place.
This keeps your store simple and avoids performance issues.
Step-by-Step Workflow to Increase Sales
Now, you might be wondering… does this apply the same way to every store?
Not exactly.
Different store stages need a different focus.
For Beginners (0–$1k/month)
At this stage, your goal is to get your first consistent sales.
You should focus on building trust and improving how your store looks.
- Add a review app so customers feel confident
- Improve your product pages using a page builder
Once that is done, set up basic email flows like abandoned cart recovery.
This helps bring back users who were interested but didn’t buy.
Keep things simple. You only need 2–3 apps.
For Growing Stores ($1k–$50k/month)
Now your goal is to increase revenue from existing traffic.
At this stage:
- Add upsell and bundle apps to increase order value
- Optimize your checkout and thank-you page
- Expand your email flows (welcome, post-purchase, win-back)
You already have visitors.
Now you focus on making each visitor more valuable.
This is where strong growth happens without increasing ad spend.
For Advanced Stores & Brands
At this level, the focus shifts to efficiency and scaling.
Instead of adding more apps, you improve systems.
- Use loyalty programs to increase repeat purchases
- Improve email targeting using segmentation
- Remove unnecessary apps to keep your store fast
You also focus on automation.
How can you reduce manual work? How can you make revenue more predictable?
That becomes the main goal.
