B2B e-invoicing in Liechtenstein
There is no mandate in Liechtenstein for using electronic invoices regarding business-to-business (B2B) transactions.
A supplier must obtain explicit consent from a buyer before voluntarily issuing an e-invoicing for a B2B transaction. E-invoices must meet the EN 16931 European Standard. If they choose to issue e-invoices, the issuer must ensure the integrity of the content and the authenticity of the origin by using, for example, an electronic signature.
