Where CarbonClick Falls Short
Sustainability Checkout Add-On, Not Revenue Architecture
CarbonClick adds an eco-contribution option at checkout. It does not create bundle flows, tiered discounts, or offer stacks that change what customers put in the cart before reaching checkout.
No Bundle Builder or Cart-Level Incentives
CarbonClick manages carbon offset contributions. It cannot build mix-and-match bundles, progressive discounts, or combined discount + shipping + gift rewards. The offset checkbox does not change cart contents or value.
Customer Opt-In Rates Vary Widely
CarbonClick depends on customers choosing to add an offset contribution. Opt-in rates run 10-30% depending on the brand's audience. Tiergain bundle offers are presented to 100% of visitors without requiring an opt-in.
Small Revenue Impact Even with High Participation
CarbonClick contributions are $0.50-2.00 per order. Even at 30% opt-in, average revenue per order from offsets is $0.15-0.60. Tiergain lifts AOV by $10+ per order across all orders. Different scale of financial impact.
Green Positioning Without Revenue Growth
CarbonClick helps position your brand as eco-friendly. That is valuable for marketing. But a green brand with $34 AOV still has a revenue problem. Tiergain fixes the revenue side. CarbonClick fixes the brand perception side.
