Characteristics of Electronic Invoicing in Switzerland

Switzerland is moving toward a more digital and efficient public administration. Although electronic invoicing is not yet mandatory in the B2B or B2C domains, the legal and technological environment is ready for broad adoption. 

While Switzerland is not part of the European Union and does not directly follow EU regulations, it has developed its own framework to promote efficiency and fiscal transparency, especially in dealings with government suppliers. 

Electronic invoicing in Switzerland is regulated primarily by the Federal Finance Administration (FFA) for the public sector and is complemented by standards promoted by eCH, swissDIGIN, and the Swiss Peppol authority.

Mandatory Use

Since January 1, 2016, electronic invoicing has been mandatory for all suppliers billing the Swiss Federal Administration for amounts exceeding CHF 5,000. This includes ministries, federal departments, and government contracting entities. Paper invoices or plain PDFs are not accepted in these cases.

For the private sector, electronic invoicing is not yet mandatory, but its use is increasingly common and recommended to optimize processes, reduce errors, and streamline accounting.

Invoice Format

Switzerland does not impose a single mandatory format for issuing electronic invoices, giving companies some flexibility in the standards they can use. However, there are formats that are highly recommended and widely accepted by public and private entities.

The swissDIGIN XML format is the suggested standard in Switzerland for electronic invoicing, especially in the B2G context.

Other accepted formats include UBL 2.0, CII XML 2.0, and the hybrid formats ZUGFeRD / Factur-X.

Electronic invoices can be sent via EDI, interoperable e-invoicing platforms, or through the Peppol network, particularly for B2G and B2B relationships.

Electronic Signature

It is not mandatory in all cases, but some public administrations or private-sector recipients may require it as an additional authentication measure.

Archiving

Electronic invoices must be retained for a period of 10 years.
