Essential Upsell & Cross Sell and STKY ‑ Sticky Add To Cart Bar both aim to increase Average Order Value (AOV) and conversions, but they approach it from different angles. Essential Upsell focuses on comprehensive upsell and cross-sell strategies throughout the customer journey, from product pages to post-purchase, offering a wide array of product recommendation types, bundling, and discount options. It seems best suited for merchants looking for a deep dive into optimizing every upsell opportunity. STKY, on the other hand, centers around improving cart conversions and streamlining the checkout process with a sticky add-to-cart bar, quick buy buttons, and a cart slider. While it also offers upsell/cross-sell within the cart drawer, its primary focus is on making the checkout process as frictionless as possible, particularly through visual cues and instant purchase options. This makes it ideal for merchants prioritizing a smooth and rapid customer purchase experience. Its addition of a countdown timer speaks to a more aggressive conversion strategy. While both apps can benefit a wide range of Shopify stores, Essential Upsell & Cross Sell caters to those with a desire to deeply strategize their upsell and cross-sell offerings while STKY is a better fit for merchants aiming to simplify the purchase journey and increase urgency during checkout.
