When using ISR Invoice (newly now QR Code Invoices, as of July 2020) or Bank Transfer, merchants can define the Payment Terms and Max. Overdue Time of the invoice that needs to get paid by the end customer.
The payment term is the amount of time the end customer has to pay the open invoice. As a default, it is set to 10 days, but it can be set to a maximum of 180 days. When after the end of the payment term is exceeded, and the invoice is still unpaid, the invoice is moved to the Overdue state.
The overdue time defines for how long the invoice will be in the overdue state before it is marked as derecognized. This time, plus the payment term, define the maximum time the transaction stays in the completed state before it is moved into the decline or fulfil state. As a default, it is set to 0 days and can be set to a maximum of 40 days.
Depending on your business module, and how you handle invoices and bank transfer payments, these are two points which you can define the time periods in the connector of your preferred payment type.
