Since the middle of last year, outgoing invoices can be created with the new QR pay-in slip. Now a final date of 30 September 2022 has been set for use of the old pay-in slips. For all invoice issuers, this means that they must convert their IS, ISR outgoing invoices to the new QR pay-in slip by this date.

The QR invoice was introduced on 30 June 2020 with an integrated QR pay-in slip with Swiss QR code. This was the beginning of a transition phase during which the traditional pay-in slips are gradually being replaced by the QR pay-in slip. PostFinance has set 30 September 2022 as the final date for use of the red (IS) and orange (ISR) pay-in slips.


Invoice issuers are requested to switch the traditional IS, ISR invoice and dunning forms to the new QR pay-in slips. There are a number of specifications regarding font, format, type of paper used, perforation, etc. which must be observed.

We will be happy to assist you with creation of your forms, whether you are using Adobe Forms, Smart Forms or SAPscript. At the same time, we ensure processing of your incoming invoices and the new electronic bank statements.
