It emphasizes creating native widgets within the store and providing comprehensive features to manage bundles including inventory synchronization and fulfillment. In contrast, Upsell & Cross‑Sell SmartFlow highlights post-purchase upsells, ease of setup, and detailed analytics for optimizing the upsell flow.
