In the Norwegian version of Business Central, Microsoft takes care of the backend Business Central Localization specific to Norway. This includes managing the Norwegian Standard Audit File - Tax (SAF-T) for sales and other activities that are not carried out at the point of sale (POS). The SAF-T file is a standardized format for reporting financial information to the tax authorities.
LS Central, on the other hand, handles the specific requirements for the Audit-file - Tax (SAF-T) related to POS transactions, digital signatures, and other regulations related to Cash Register Systems in Norway. These requirements are specified by Lovdata, the Norwegian legislation database.
