Essential Upsell & Cross Sell vs Fly: Bundles & Quantity Breaksfor Shopify (2026)
Essential Upsell & Cross Sell and Fly: Bundles & Quantity Breaks are both highly-rated Shopify apps designed to increase Average Order Value (AOV) through upsells, cross-sells, and product bundles. Essential Upsell positions itself as a comprehensive solution with a strong focus on one-click upsells, post-purchase upsells, and automated discount promotions tied to product recommendations. It leans heavily on showcasing frequently bought together (FBT) items and related products across various stages of the customer journey, including the product page and cart drawer. Fly: Bundles & Quantity Breaks, on the other hand, centers around creating powerful product bundles and quantity-based discounts. It emphasizes flexibility in bundle creation, including fixed bundles, tiered quantity breaks, and automated free gifts, with a pledge of zero coding impact on store speed. While both apps offer FBT features, their core focuses differ. Essential Upsell offers a broad suite of upsell and cross-sell techniques, whereas Fly: Bundles & Quantity Breaks prioritizes crafting compelling bundle offers and tiered discounts to drive larger purchases. The higher review count of Essential Upsell suggests a broader user base, potentially indicating a more established presence or wider appeal. However, the slightly lower review count for Fly: Bundles & Quantity Breaks does not imply inferiority, but rather a different, possibly more niche focus and potentially a shorter time in the market, or a more specific target audience.

Our Verdict
For merchants seeking a comprehensive, 'set and forget' solution with broad upsell and cross-sell capabilities, including post-purchase options and automated promotions, Essential Upsell & Cross Sell appears to be the stronger choice.

However, if the primary goal is to create compelling product bundles, offer attractive quantity discounts, and incentivize bulk purchases with free gifts and inventory management features, Fly: Bundles & Quantity Breaks is the better option. Its focus on bundling provides more specialized tools for crafting and managing complex product combinations. Ultimately, the best app depends on the specific upselling and cross-selling strategy the merchant wants to implement.
