If you're searching for the best Shopify apps to increase sales, you're not alone. Thousands of Shopify merchants rely on specialized apps for email marketing, upselling, loyalty programs, checkout optimization, and conversion rate optimization (CRO). But installing random tools doesn’t increase revenue; building the right Shopify app stack does.
But here is the challenge: there are thousands of apps in the Shopify App Store, each promising to transform your business. Which ones actually deliver? Which categories of tools should you prioritise? And how do you build a stack that works together rather than against itself?
Here we have evaluated and compiled the 20 best Shopify apps across 10 critical revenue categories. Not based on marketing claims, but on features, community ratings, and proven ecommerce outcomes.

Pricing: Free Plan Available | Paid Plans from $49/month
RATING & REVIEWS: 4.8/5 | 6,500+ reviews
View App on Shopify App Store ↗
Acquiring a new customer costs five times more than retaining an existing one. That single statistic explains why loyalty programmes are not a nice-to-have. They are a critical revenue strategy.

Pricing: Free Plan Available | Paid Plans from $4.99/month
RATING & REVIEWS: 4.9/5 | 5,400+ reviews
View App on Shopify App Store ↗
Most Shopify merchants obsess over getting customers to the checkout and then stop.

RATING & REVIEWS: 4.9/5 | 2,500+ reviews
View App on Shopify App Store ↗
Amazon built one of the most profitable retail empires in history. And product bundling is one of the core strategies that made it work.

Pricing: Free Plan Available | Paid Plans from $18/month
RATING & REVIEWS: 4.8/5 | 1,500+ reviews
View App on Shopify App Store ↗
Every visitor to your store has different interests, different budgets, and different intentions. So why does the same static product page greet every single one of them?

11. Quantity Breaks & Discounts
Pricing: Free Plan Available | Paid Plans from $9.99/month
RATING & REVIEWS: 4.9/5 | 1,200+ reviews
View App on Shopify App Store ↗
One of the most reliable ways to increase average order value is elegantly simple. Give customers a financial incentive to buy more. Quantity break pricing like 'Buy 3, save 10%. Buy 6, save 20%' is a proven strategy used by some of the world's most successful retailers. This app makes it straightforward to implement tiered volume discounts across your entire Shopify catalogue, displaying clear pricing tables that motivate customers to upgrade their purchase without requiring any custom development.

- Minimum and maximum purchase quantity controls
- BOGO (Buy One Get One) deal configuration

Pricing: Free Plan Available | Paid Plans from $9.99/month
RATING & REVIEWS: 4.8/5 | 5,800+ reviews
View App on Shopify App Store ↗
Optimizing your Shopify store's conversion rate typically means installing multiple single-purpose apps that include a countdown timer here, a trust badge there, a free shipping bar somewhere else. Each app adds cost, complexity, and potential page speed impact. Hextom Ultimate Sales Boost takes a different approach. It combines all of these conversion tools, like countdown timers, free shipping bars, BOGO offers, urgency labels, trust badges, and stock countdowns into a single, affordable, high-performance app.

- Stock countdown urgency labels to accelerate purchase decisions

Pros & Cons

|---|---|
| Multi-feature CRO toolkit replaces several single-purpose apps | Individual features may lack depth compared to dedicated single-purpose apps |
| Significantly reduces app stack complexity and total monthly cost | Displaying too many simultaneous urgency widgets can overwhelm and deter customers |
| Affordable pricing for the breadth of functionality provided | Design customisation options are relatively limited |
| Straightforward configuration accessible to non-technical merchants | Some advanced features are reserved for higher-tier plans |
| Regularly updated with new features and conversion tools |

Pricing: Free Plan Available | Paid Plans from $14.99/month
RATING & REVIEWS: 4.8/5 | 900+ reviews
View App on Shopify App Store ↗
The shopping cart is where purchase intent peaks. A customer who opens their cart has mentally committed to buying. They are reviewing, confirming, and preparing to pay. This is the single best moment to present a relevant add-on offer. UpCart transforms Shopify's standard cart into a branded slide-out drawer with built-in upsell recommendations, add-on widgets, and free shipping progress bars. Capturing incremental revenue at precisely the right moment in the purchase journey.

| PROS | CONS |

Pricing: Free Plan Available | Paid Plans from $19/month
RATING & REVIEWS: 4.8/5 | 2,900+ reviews
View App on Shopify App Store ↗
Here’s the challenge every e-commerce store faces: the majority of visitors who browse your site never leave an email address. They browse, consider, and leave and you have no way to reach them again. Brevo PushOwl solves this problem.

Dramatically expanding your re-engagement reach beyond your email list.

|---|---|
| Reaches anonymous visitors who have not provided an email address | Push notifications are only supported in certain browsers (Chrome, Firefox, Edge) |
| High open rates that consistently outperform email for short-window offers | iOS Safari support remains limited |
| Multi-channel capability for push, email, and SMS in one platform | Push subscriber numbers are typically smaller than email lists |
| Automated cart recovery and product alert flows work passively | Overuse of push notifications can lead to subscriber opt-outs |

SMS Marketing (Dedicated)
15. Postscript SMS Marketing
Pricing: Paid Plans from $100/month
RATING & REVIEWS: 4.8/5 | 1,900+ reviews
View App on Shopify App Store ↗
The reality is that the average SMS open rate is 98%. The average email open rate is around 20%. If you are not leveraging SMS marketing, you are communicating with your customers through a channel they check one-fifth as often as the one you are ignoring. Postscript is the dedicated, compliance-first SMS platform built specifically for Shopify. It enables merchants to run highly targeted text campaigns, automated flows, and two-way conversations that convert at exceptional rates.

| Exceptional ROI for time-sensitive promotions and flash sales |
Social Proof & Urgency (Trust + FOMO)
16. Sales Popup Autoketing – POP
Pricing: Free Plan Available | Paid Plans $4.99/month
RATING & REVIEWS: 4.8/5 | 3,600+ reviews
View App on Shopify App Store ↗
People trust people. It is one of the most fundamental principles of human behaviour. And it applies just as powerfully to online shopping as it does to in-person recommendations. Sales Popup by Autoketing leverages this psychology by displaying real, live purchase notifications across your store. When a visitor sees that someone in London just bought the exact product they are considering. It eliminates doubt, builds trust, and creates a sense of urgency. FOMO(fear of missing out) is a powerful motivator, and this app activates it deliberately.
Key Features
- Real-time recent purchase notifications drawn from actual store orders
- Customisable notification style, position, delay, and display duration
- Product image, name, and buyer location displayed in notifications
- Countdown timers and stock countdown widgets to amplify urgency
- Visitor counter and active viewer displays for high-traffic periods
- Mobile-optimised notification formats
- Multiple notification types, including sales, reviews, and visitor activity
Pros & Cons
| PROS | CONS |
|---|---|
| Powerful social proof mechanism based on real psychological drivers | Overuse creates a spammy feel that can damage trust rather than build it |
| Extremely fast setup with full operation within minutes | Increasingly savvy shoppers may dismiss social proof pop-ups |
| Multiple notification types for different contexts and goals | Less impactful for established stores with extensive genuine reviews |

| Free plan available to get started without an upfront cost |

Pricing: Free Plan Available | Paid Plans from $5.99/month
RATING & REVIEWS: 4.7/5 | 500+ reviews
View App on Shopify App Store ↗
In a crowded e-commerce landscape, trust is currency. Shoppers are sophisticated, and they know that any store can claim to be popular, but seeing real, live evidence of other people purchasing is a different matter entirely. SP Sales Pop Up by Meetanshi delivers exactly that: authentic 'just purchased' notifications drawn from real orders, displayed as lightweight, unobtrusive popups that build credibility without slowing your store or overwhelming your visitors.
Key Features

Pros & Cons
| PROS | CONS |
|---|---|
| Exceptionally lightweight for minimal impact on store page speed | Limited feature set compared to full-suite CRO platforms |

| Simple setup with straightforward configuration | Less impactful for very high-traffic stores where social proof is already self-evident |
| Free plan available with no upfront commitment | Design customisation options are minimal on lower-tier plans |
| Clean, unobtrusive notification design that feels natural rather than pushy |

RATING & REVIEWS: 4.9/5 | 730+ reviews
View App on Shopify App Store ↗
Your customers check their phones over 90 times per day. A branded mobile app puts your store in their pocket.

19. Checkout Extensions Pro – MT
Pricing: Free for up to 250 subscribers | Paid Plans from $35/month
RATING & REVIEWS: 4.9/5 | 1,100+ reviews
View App on Shopify App Store ↗
Every merchant optimizes their homepage, their product pages, and their ad campaigns. Yet one of the most critical pages in the entire customer journey. The checkout is left almost entirely unoptimized. Checkout Extensions Pro changes that.

Pricing: Free Plan Available | Paid Plans from $19.95/month
RATING & REVIEWS: 4.5/5 | 1,400+ reviews
View App on Shopify App Store ↗
Sold out does not have to mean lost revenue. In fact, for merchants who handle it strategically, a sold-out product can become a demand validation tool and a revenue opportunity. WOD PreOrder Now enables Shopify merchants to accept pre-orders for out-of-stock or upcoming products, capturing customer commitment and payment before items are even available.

- Partial payment and deposit options to reduce financial risk for customers
- Automated shipping confirmation emails when items are fulfilled
- Pre-order discount incentives to reward early commitment

- Mixed cart management handles pre-order and in-stock items in the same order
- Pre-order tagging for streamlined Shopify order management
Pros & Cons
| PROS | CONS |
|---|---|

You now have a comprehensive view of the 20 best Shopify apps available. But knowing the tools is only half the challenge. Knowing how to deploy them together strategically is what separates stores that grow from stores that plateau.
Think of your app stack as a customer journey map. Every stage from the moment a visitor first lands on your store to the moment they become a loyal, referring customer has a corresponding tool that can optimize the outcome. Here is the framework that the most successful Shopify merchants follow:
| Stage 1 | Capture | Convert anonymous traffic into subscribers using Privy, Omnisend, or Klaviyo’s on-site forms before visitors leave. |
| Stage 2 | Nurture & Convert | Turn subscribers into first-time buyers through automated email and SMS flows via Klaviyo, Omnisend, or Seguno. |
| Stage 3 | Increase Order Value | Boost AOV at every touchpoint with ReConvert post-purchase, UpCart in-cart offers, and Frequently Bought Together on product pages. |
| Stage 4 | Build Trust | Reduce hesitation for new visitors using social proof tools (Sales Pop, SP Sales Pop Up) and checkout trust badges. |
| Stage 5 | Retain & Reward | Keep customers returning with Smile.io loyalty points, VIP tiers, and ReferralCandy referral incentives. |
| Stage 6 | Re-engage | Bring back lapsed customers via Postscript SMS, PushOwl push notifications, or Shopney app push campaigns. |
| Stage 7 | Optimise Continuously | Use A/B testing, revenue attribution, and analytics from your email, upsell, and loyalty tools to improve every stage over time. |
Where to Start?
Feeling overwhelmed? You do not need to install all 20 apps at once. In fact, doing so would be counterproductive. Start with one tool from each of the three most impactful categories for your specific business:
- Email marketing automation (Klaviyo or Omnisend), because capturing and nurturing leads is the foundation of everything else
- An upsell or AOV tool (ReConvert or UpCart because increasing the value of existing traffic costs far less than acquiring new traffic
- A trust and social proof tool (Smile.io, Sales Popup) because conversion rate improvements at any stage compound across your entire sales volume
Measure the impact of each tool for 30 to 60 days before adding the next layer. Build your stack deliberately, data-first, and your investment in these tools will compound into measurable, scalable revenue growth.
