Verdict on BST

BST is the best option if your primary cross-sell strategy is Amazon-style "frequently bought together" recommendations. The AI-powered suggestions are genuinely smart, and the mobile-first design ensures bundles look great on every device. The free plan is limited to 1 manual bundle, but the Core plan unlocks AI recommendations at a fair price. If you want focused cross-sell rather than a full bundle builder, BST delivers.

Verdict on Interakt

Interakt is a strong WhatsApp marketing platform for markets where WhatsApp dominates customer communication, particularly India and Southeast Asia. With 205 reviews and features like abandoned cart recovery and COD confirmation, it fills a real need. However, its starting price of $21/month is steep for small stores, and it lacks the Built for Shopify badge.
