Opus Cart Upsell Cart Drawer and Upsell Engine by Square both aim to enhance AOV through upsells and cross-sells, but they cater to different segments of the Shopify market. Opus positions itself as a comprehensive cart customization and optimization suite, offering a wider array of features beyond simple upsells, including free gifts, rewards bars, urgency timers, and abandoned cart analytics. Its emphasis on code-free customization makes it appealing to merchants who want powerful features without technical expertise. Upsell Engine by Square, while sharing the same fundamental goal, currently lacks substantial user validation with only one review. Opus offers a well-rounded feature set that is focused on conversions through cart optimization with progress bars, free gifts, and discount offerings. The choice between the apps in 2026 depends largely on the size of the store, the level of customization needed, and confidence level based on the app's user rating and reviews.
