In assignment by PaCoS (Payments Committee Switzerland), a committee set up by the Swiss Payments Council (SPC), a working group elaborated the Swiss recommendations for implementation of the format standards for payments initiation based on the ISO 20022 standard. The recommendations, which are supported by all Swiss financial institutions, are based upon the basic documentation issued by the ISO and the EPC (European Payments Council) and are reflected in the two rulebooks, the “Swiss Business Rules” and the “Swiss Implementation Guidelines”.
