Where Amai Upsell+ Falls Short
Post-Purchase Timing Limits Conversion
Amai shows upsells after the customer already paid. Accept rates on post-purchase upsells run 5-15%. Tiergain bundle offers appear before checkout when buying intent is highest. Pre-purchase bundle adoption runs 30-50%.
Single-Item Upsells, Not Bundle Architecture
Amai suggests one additional product at a time. Tiergain builds complete bundle experiences with 10 architectures, category rules, and progressive tiers. An upsell adds one item. A bundle restructures the entire order.
No Combined Reward Stacks
Amai offers discounted upsells or free gifts as separate promotions. Tiergain combines discount + free shipping + free gift in one progressive bundle. Three stacked rewards in one offer drive higher AOV than separate single-item promotions.
No Dollar-Based Thresholds
Amai upsells are triggered by product or cart contents, not dollar amounts. Tiergain supports quantity and dollar thresholds. Spend $150, unlock free shipping + gift. Dollar thresholds work for every price point.
Discount-Heavy Approach Can Compress Margins
Amai upsells often use heavy discounts (30-50% off) to get post-purchase accepts. Tiergain bundle rewards add perceived value (free shipping, free gifts) without cutting the core price. Value-add rewards protect margins.
