In this fourth installment of our five-part series on essential Shopify apps, we focus on apps that can help you maximize sales and build customer loyalty. We'll explore categories such as loyalty programs, product recommendations/upsells, subscriptions, and gift certificates. These apps can help you increase average order value, encourage repeat purchases, and create a more engaging shopping experience for your customers.
1. Loyalty Programs
What It Does: Loyalty program apps help merchants create and manage customer loyalty programs, rewarding customers for repeat purchases, referrals, and engagement.
Examples:
- Smile: Loyalty & Rewards: Smile.io powers loyalty, referrals, and VIP rewards programs that help increase sales and repeat purchases, save on acquisition costs, and boost brand loyalty. Creating a loyalty program with Smile takes only minutes—no coding required! Managing loyalty with Smile is effortless, including easy integrations with your favorite apps.

Improve customer experiences with a loyalty page integrated within your site and shopper journey. Use loyalty points and rewards to drive enrollment and increase returning customer rates. Reduce acquisition costs with incentives for referrals, reviews and social media engagement.

2. Product Recommendations/Upsells
What It Does: Product recommendation and upsell apps suggest additional products to customers, encouraging them to add more items to their cart and increasing average order value.
Examples:
- Rebuy Personalization Engine: Rebuy unlocks the power of personalization by combining proprietary AI/ML technology with modern (no-code, low-code, and custom code) software, industry-leading integrations, fully-customizable search, merchandising rules, and A/B/n testing. This holistic solution allows brands to fuel data-driven shopping experiences throughout the entire customer journey from the homepage to checkout to post-purchase and beyond. To enhance customer engagement and boost the average order value (AOV) for one of our clients, we recently installed the Smart Cart Progress bar, which displays progress towards earning free gifts with purchase and free shipping.
- BOLD Upsell AI Powered Upsells: Maximize average order value with AI upsells & cross-sells displaying the right offer, at the right time, to the right customer. AI-Powered Smart Offers show the highest converting offer on autopilot! Easily switch between AI-powered and manual offers. Create high-converting funnels with true upsells that upgrade, cross-sells that add on and downsells. Upsell and cross-sell on the product page, in cart, cart drawer, in checkout, post purchase one-click upsells after checkout and upsell by email!
3. Subscriptions
What It Does: Subscription apps allow customers to sign up for recurring purchases, enabling them to receive products regularly without needing to reorder each time.
Examples:
- Recharge Subscriptions: From insights to dynamic subscriber experiences and a subscription core trusted by leading brands, Recharge assists in driving more revenue from a subscription strategy. Their aim is to help build buyer routines that endure. With no-code customer portals and tiered discounts, subscription management is made easier. Recharge has introduced a new feature that allows users to create Bundles within the app. These bundles can be either preset or dynamic, which gives businesses the ability to expand their product offerings without having to increase their inventory. Businesses can monitor their performance and optimize results with analytics and insights. Subscription experiences include offering free gifts or discounts on upcoming orders, saving cancellations with personalized retention offers, and more.
- Skio Subscriptions: Skio Subscriptions is a powerful app designed to help Shopify merchants effortlessly implement and manage subscription services for their products. With its user-friendly interface, Skio allows businesses to create customizable subscription plans that enhance customer loyalty and drive recurring revenue. The app offers robust features like automated billing, customer management, and detailed analytics, enabling merchants to optimize their subscription offerings for maximum profitability.

4. Gift Certificates
What It Does: Gift certificate apps allow merchants to sell digital gift cards that customers can purchase for others, offering a convenient gift option that can be redeemed in the store.
Examples:
- Rise.ai: Gift Cards & Loyalty: Brands use Rise.ai to grow retention and loyalty with Store Credit rewards and Gift Cards. Our solution drives higher RPRs for comprehensive loyalty programs, offering cash value credits, not points. Increase AOV and upsells with tailored Cashback workflows, replacing discounts for higher ROI. Open new revenue streams with Gift Cards, referrals, and memberships. Reduce losses w/Store Credit for refunds & returns. Unite all rewards into a branded wallet to boost LTV and retention.
- Gift Card Hero: Gift Card Hero is designed to solve the gifting dilemma by offering a system that allows users to easily purchase, send and redeem gift cards. The gift card app lets you upload your custom designs or use predefined ones, top-up a gift card balance, sell physical gift cards along with eGift vouchers and use POS tools. This app is an all-in-one tool to grow revenue during seasonal holidays, build long-lasting customer relationships via personalized gift card certificates and to help you acquire new customers.
