For Sweden, by law you are required to have "Godkänd för F-skatt" on sales invoices.

There is a similar law in Norway where you have to state "Foretaksregisteret" on sales invoice, see: https://learn.microsoft.com/en-us/dynamicsax-2012/appuser-itpro/nor-select-the-parameter-to-print-enterprise-register-on-sales-documents

In Norway this was implemented a long time ago. I do not know why this is not implemented for sweden.
