E-invoicing in Liechtenstein (2023)

E-invoicing, or electronic invoicing, is the process of sending and receiving invoices electronically, instead of using traditional paper-based methods. E-invoices offer numerous benefits, including increased efficiency, reduced costs, and improved accuracy in the invoicing process.

In Liechtenstein, e-invoicing is becoming increasingly popular. The government has taken steps to support and promote the adoption of e-invoicing by businesses across the country. They have implemented regulations and guidelines to facilitate the use of electronic invoicing and to ensure its legal validity.
