Unfortunately, Sezzle Premium payments cannot be rescheduled. Whether you paid upfront (in 1 payment) or in 4 payments, once you opt-in for the annual subscription plan, these payments cannot be rescheduled or refunded. You can update the payment method if you need to, but this must be done before the payment is processed at least 24 hours in advance.
Sezzle Premium is available in the Sezzle mobile app for U.S. Shoppers only. This beta version is currently being tested and because of this availability and pricing plans for Sezzle Premium may vary by individual.
