Where Sezzle Falls Short
Payment Installment Platform, Not Revenue Architecture
Sezzle adds a pay-in-4 option at checkout. It does not create bundle flows, tiered pricing, or combined rewards. Splitting a payment does not change what the customer put in the cart.
No Bundle Builder or Cart-Level Offers
Sezzle handles payment processing in installments. It cannot build mix-and-match bundles, free shipping thresholds, or combined discount + shipping + gift rewards that change cart contents.
6% Transaction Fee Is the Highest Among BNPL
Sezzle charges merchants approximately 6% + $0.30 per transaction. On a $100 order, that is $6.30. Tiergain is flat-rate at $50/month. At 200 orders/month averaging $50, Sezzle costs $1,260/month vs Tiergain at $50.
Niche Audience Limits Reach
Sezzle targets younger, budget-conscious shoppers. Not all customer demographics prefer BNPL. Tiergain bundle offers work for every customer regardless of age, budget preference, or payment method.
Installments Without Better Offers Miss the Bigger Win
Sezzle makes a $34 cart feel like $8.50. That helps conversion. But the order is still $34. Tiergain lifts the cart to $48 through bundle architecture. Apply Sezzle to the bundle and each installment is $12 - same perceived ease, 28% more revenue.
