General rule
If the operating seat of your company is located in the Dutch language area, the law prescribes that all company documents – including invoices – must be drawn up in Dutch. If this rule is violated, the invoice is null and void.
Exceptions
Since this rule is not always feasible in practice, the legislation was extended by the decree of 7 July 2017 containing various provisions relating to the policy area Work and Social Economy.
Since this decree, the company has the option to also prepare its invoice in another language, if the following conditions are met:
- +the invoice must be drawn up in a language that can be understood by both parties;
- +the counterparty must be located in one of the member states of the European Union or of the European Economic Area (hereinafter: ‘EEA’).
