BKT: Bundle Kit vs Essential Upsell & Cross Sellfor Shopify (2026)
BKT: Bundle Kit and Essential Upsell & Cross Sell, while both aiming to increase revenue for Shopify merchants, tackle the problem from different angles. BKT focuses on enabling merchants to sell products in bundled formats, managing inventory of those bundles, and facilitating fulfillment with 3PL providers. Its core strength lies in creating and managing complex bundle offerings like kits, multipacks, and tiered products, presented as standalone products. Essential Upsell & Cross Sell, on the other hand, prioritizes increasing Average Order Value (AOV) through strategic upsells and cross-sells at various customer touchpoints, including product pages, cart drawers, and post-purchase flows. It leverages techniques like frequently bought together suggestions, product recommendations, and automatic discounts.
