What are the best Shopify apps?

Choosing the best Shopify apps to increase sales in your store highly depends on how your business makes money. It’s about fit, not popularity.

A note on AI-powered revenue-boosting Shopify apps: While many Shopify apps offer some AI-related features, as of this writing, most apps’ AI capabilities are relatively nascent and don’t offer enough features to justify being termed a “revenue-boosting Shopify AI app”. However, considering that AI adoption is increasing at a rapid pace, we’re keeping an eye on developments and will update this post as needed.

Based on our 17+ years of experience in the ecommerce industry, these are the best apps to increase sales on Shopify:

1. Dotstore Shopify Extra Fees Manager
2. Klaviyo: Email Marketing & SMS
3. Kaching Bundles App & Upsells
4. Judge.me Product Reviews app
5. Smile: Loyalty Program Rewards
6. SEOWILL: AI SEO & AI Blog Post

Below, we’ll outline the features and benefits of each app.

Best Shopify app to increase sales via custom fees – Dotstore Shopify Extra Fees Manager

Dotstore Shopify Extra Fees Manager is a powerful app that lets you add custom fees, surcharges, and optional add-ons to your store.

Available in both free and paid versions, it gives you the flexibility to set fixed and percentage-based charges, as desired.

For example, it may make sense to set a flat fee for package handling, while a percentage fee may work better for a credit card processing surcharge.

The app can trigger fees based on cart value, products in the cart, customer location, selected shipping method, payment method, item quantity, specific dates, and other conditions.

It works for a variety of use cases, such as adding handling fees, surcharges, optional add-ons like gift wrapping, insurance, premium packaging, or rush processing, and others.

Dotstore Shopify Extra Fees Manager supports product-level, collection-level, and cart-level pricing logic so merchants can precisely target how the charges are applied in their store.

Plus, customers are shown every charge as a separate line item during checkout, so they are abundantly clear about what the extra charge is for.

Top features

1. ✔️ Advanced conditional logic. You can apply charges based on cart total, products, customer location, shipping method, payment method, and other conditions.
2. ✔️ Different custom fee types. It lets you create both flat and percentage fees. Also, you can make charges mandatory (think: tariffs or small-order fees) or optional upgrades (think: gift wrapping, rush processing fees, etc.).
3. ✔️ Product-level and cart-level. Specify which products the fees should apply to: specific products, specific categories, or the entire cart.
4. ✔️ Custom fee scheduling. You can schedule start and end dates so fees activate automatically without any manual action required.
5. ✔️ Multi-currency support. Stores thatsell internationally will appreciate that fees can be automatically adjusted based on the customer’s currency. This ensures that pricing stays consistent and avoids friction in the checkout flow.

Best Shopify app to increase sales via email marketing and SMS – Klaviyo

Klaviyo is a lifecycle marketing platform that helps Shopify merchants boost revenue by combining email, SMS, WhatsApp, mobile push notifications, pop-ups, signup forms, customer data, and automation.

After you connect it to Shopify, its platform syncs store data and lets you automatically create and send campaigns based on customers’ past behavior or real-time activities. For example, if a shopper abandons their cart, views a product multiple times, purchases a subscription item, or hasn’t ordered in months, you can trigger personalized follow-up messages automatically.

Klaviyo stands out from other email and SMS marketing platforms due to its robust automation capabilities, meaning that you can trigger marketing messages based on various data points without any manual intervention. You can set up flows for welcome sequences, browse abandonment, post-purchase follow-ups, winback campaigns, back-in-stock alerts, review requests, birthday offers, reorder reminders, and more.

To illustrate this: If, for example, a shopper adds running shoes to their cart but leaves before checking out, Klaviyo can automatically send an abandoned cart email, followed by an SMS reminder a few hours later. If the product goes low in stock or drops in price, another message can be triggered without manual work.

Klaviyo boasts advanced segmentation features that empower you to send personalized marketing messages. Instead of blasting the same campaign to everyone, you can create audiences based on purchase history, browsing behavior, location, average order value, product category interest, or engagement level. This usually results in higher open rates, stronger click-through rates, and better conversion performance.

In addition, its strong reporting and attribution help you understand revenue generated from email and SMS campaigns. You can easily track opens, clicks, conversions, ROI, and campaign trends over time.

Best Shopify app to increase sales via upsells – Kaching Bundles App & Upsells

The Kaching Bundles & Upsells app is built around a simple idea: encourage customers to buy more in a single order by presenting higher-value offers at the right moment. It accomplishes this objective through a myriad of tactics, namely product bundles, quantity breaks, free gifts, volume discounts, and others.

Kaching Bundles & Upsells app’s core strengths are variety and flexibility of promotion types, bundle types, and pricing options. For instance, it lets you create fixed bundles, mix-and-match bundles, multipacks, variant bundles, subscription boxes, wholesale packs, frequently bought together offers, and custom product sets.

You can run percentage discounts, flat discounts, quantity breaks, tiered pricing, BOGO offers, free shipping thresholds, bulk pricing, and dynamic pricing structures. This makes it ideal for stores across different product catalogs, niches, and business models.

For example, a supplements store can offer a “Buy 2, Save 10%” deal. A skincare store might bundle a cleanser, toner, and moisturizer at a discount compared to buying each item separately.

The Kaching Bundles & Upsells app uses the “Frequently Bought Together” feature along with AI-driven recommendations to help surface relevant products customers may have missed. Upsell recommendations are presented on the product page while purchase intent is highest, and customers can add them with just a single click.

Best Shopify app to increase sales via ratings, reviews, and UGC – Judge.me Product Reviews app

Studies consistently show that online shoppers want reassurance before they commit to a purchase. Across all product verticals (but especially fashion, beauty, home décor, and lifestyle brands), seeing genuine customers use products in real-life contexts often carries more weight than polished studio images.

Judge.me Product Reviews app lets you collect star ratings, product reviews, along with photo and video UGC, and showcase them in a conversion-friendly interface on your website. Its review system is built to scale; you can collect an unlimited number of reviews.

Instead of manually chasing feedback, you can automate review requests to be sent after products have been delivered. Review requests can be triggered by email, SMS, push notification, or custom workflows based on order events. For example, a skincare store can email customers three days after order delivery to nudge them to review the products received, complete with uploaded before-and-after photos.

Merchants can reward customers for their reviews with coupons or referral incentives. This encourages more customer engagement and makes it much easier to gather fresh reviews consistently.

This customer reviews app enables you to showcase reviews in multiple ways across your storefront, not just on product pages. You can add star ratings under product titles, review summaries on collection pages, testimonial sliders on the homepage, carousels, badges, media galleries, and dedicated all-reviews pages. Showcasing trust signals throughout the buying journey makes them infinitely more effective.

An underrated bonus of using Judge.me to set up a robust review system on your store? Star ratings, structured data, review-rich content, and rich snippets can improve your site’s visibility in search results and increase click-through rates.

Best Shopify app to increase sales via loyalty programs – Smile: Loyalty Program Rewards

With nearly 5,000 reviews and a 4.9-star rating, Smile: Loyalty Program Rewards is arguably the most popular Shopify loyalty program app. It enables you to launch a loyalty program that rewards purchases with points and exclusive perks that encourage customers to keep shopping in your store.

You can create reward tiers that assign customers points for completing certain activities, such as signing up, completing purchases, birthdays, referrals, sharing product reviews, or other actions you define. Customers who reach a certain spend threshold are moved to a higher tier that unlocks additional coveted perks and benefits.

Merchants have the flexibility to tailor incentives as desired, such as coupons, discounts, exclusive pricing, free shipping, early access to new products, free gifts, or premium perks. This keeps customers engaged with your brand and gives them a clear reason to purchase repeatedly.

To keep incentives front and center across the buying journey, you can embed loyalty messaging on-site: on product pages, in the cart and checkout, within customer accounts, using built-in pop-ups and banners, and in a dedicated rewards hub.

Every stellar loyalty program relies on solid data. Smile collects in-depth analytics and benchmark data to help you understand your loyalty program’s performance over time, including customer participation, repeat purchase impact, and more. Plus, it deeply integrates Klaviyo, Judge.me, Gorgias, and other tools to sync loyalty data with email, reviews, and support workflows.

Best Shopify app to increase sales via SEO – SEOWILL: AI SEO & Blog Post

SEOWILL: AI SEO & Blog Post (formerly named SEOAnt) combines SEO audits, content generation, technical fixes, and speed optimization to help Shopify stores improve visibility across Google AI Overviews, ChatGPT, Gemini, and other modern AI-driven discovery platforms.

As an SEO and AEO superapp, it packs a ton of features into a single interface. It can suggest relevant keywords, generate optimized blog content around buying guides or product comparisons, improve metadata across product and collection pages, and much more.

Its core feature, SEO checker, scans your store for missing meta descriptions, weak titles, broken links, image optimization gaps, and indexing problems.

In addition, it provides on-page SEO guidance that helps merchants identify content gaps, improve headings, refine copy, and optimize pages using search-result insights. Surfacing low-hanging, high-impact fixes like these can greatly improve your site’s organic search performance over time.

SEOWILL’s technical SEO automation helps stores stay healthy behind the scenes. It supports redirects for broken URLs, structured data markup, sitemap improvements, robots settings, and metadata enhancements that help search engines understand your store more clearly.

Another useful feature is its built-in AI blog builder that helps generate keyword-focused blog posts that attract top-of-funnel traffic and support product discovery. Its content tools support multilingual publishing, templates, embedded products, images, videos, internal linking, and article optimization.

What are the overall best apps for Shopify?

Shopify provides a solid infrastructure to build an ecommerce store out of the box. To keep its platform lean, not every ecommerce-related feature is built into it by design. So you need apps to make the most of it.

In this guide, we shortlisted the best Shopify apps to increase sales in 2026. Each one solves a different growth problem and has a proven track record across a wide range of ecommerce niches, from fashion and beauty to home goods, consumables, gifts, B2B stores, and others.

That said, there’s no single “best” app for every merchant. The right choice depends on where your store is currently underperforming.

Our advice? Don’t install all the apps at once. Start with the top three from this list. Test them properly, use their demos where available, and measure real outcomes like average order value, conversion rate, repeat purchase rate, and net profit.

Here are the three apps we’d recommend starting with if you want the best Shopify apps to increase sales quickly:

1. Dotstore Shopify Extra Fees Manager: Add custom fees, surcharges, and optional add-ons to the checkout flow. You can create fixed or percentage-based charges and apply them based on cart value, products, location, shipping method, payment method, or customer type. It also supports taxable or tax-exempt fees, scheduled charges, multi-currency pricing, and clear line-item display in the checkout.
2. Klaviyo: Combines email, SMS, segmentation, and automation in one platform. You can create abandoned cart flows, welcome sequences, browse abandonment reminders, win-back campaigns, reorder prompts, and post-purchase upsells based on real customer behavior.
