[Deprecated] Unzer Installment
DeprecatedLearn more about Unzer Installment and its workflow
Unzer installment is a popular payment method both for merchants and their customers especially for larger basket sizes. The merchant ships their goods and the customer pays their order via direct debit once the goods arrived in small installments. Unzer offers to check for received funds and commences matching. Unzer will buy the entire claim and pay the full amount to the merchant upon the shipping call.
Additionally, Unzer will also send payment reminders to the customer if they don’t pay in a predefined time frame. If the end customer does not pay after they received the final then the claim is handed over to a debt collector.
