Where Klarna Falls Short
Payment Option, Not Revenue Architecture
Klarna adds a payment installment option at checkout. It does not create bundle flows, tiered discounts, or offer stacks. Payment flexibility and offer structure solve different parts of the conversion equation.
No Bundle Builder or Cart-Level Offers
Klarna processes payments in installments. It cannot build mix-and-match bundles, progressive discounts, or combined discount + shipping + gift rewards. The payment method does not change what is in the cart.
3.29% Transaction Fee on Every Order
Klarna charges merchants 3.29% + $0.30 per transaction. On a $100 order, that is $3.59. Tiergain is flat-rate at $50/month with zero per-transaction fees. At 500 orders/month averaging $50, Klarna costs $1,795/month. Tiergain costs $50.
BNPL May Increase Return Rates
Klarna's pay-later model can increase return rates 15-20% because customers buy more impulsively. Tiergain bundles built on the Offer Stack Playbook add perceived value, which reduces returns because customers understand why they bought each item.
Installments Do Not Change Cart Contents
Klarna makes the same $34 cart easier to pay for. Tiergain makes the cart worth $48. Both increase likelihood of purchase completion. Only Tiergain increases what is purchased.
