Unzer Invoice Secured

Learn more about Unzer Invoice Secured and its workflow

Invoice Secured is a very convenient payment method both for merchants and their customers. The merchant ships his goods and the customer pays their order via bank transfer once the goods arrived. Unzer offers to check for received funds and commences matching. If the customer doesn’t pay within a certain timeframe the merchant will receive the funds from Unzer. Additionally Unzer will also send two payment reminders to the customer if he doesn’t pay in a predefined timeframe.

If the customer doesn’t pay after receiving the reminders the claim will be transferred to an insurance company and the merchant will receive the funds from them.

  • Ease of use: The customer can easily step through the checkout because he will be provided by the merchant’s account number in the end and can send the money via his own bank account.
