Electronic Invoicing in Switzerland
Is e-invoicing mandatory in Switzerland ?
E-invoicing is mandatory for Business-to-Government (B2G) transactions when suppliers send electronic invoices to federal government entities. For Business-to-Business (B2B) transactions, electronic invoicing remains voluntary.
Who is affected?
E-invoicing is mandatory for suppliers engaging in B2G transactions. For B2B transactions, it is not required but is encouraged.
Compliance requirements
B2G: Suppliers must send invoices electronically in a structured format when the contract value is CHF 5,000 or more.
B2B: While there are no specific requirements for B2B transactions, businesses can use the swissDIGIN, ZUGFeRD or Factur-X formats for e-invoicing.

Standards & Platforms
What formats are required in Switzerland?
Switzerland's e-invoicing standard is SwissDIGIN, which defines the content and formats for exchanging invoicing data. The ZUGFeRD or Factur-X invoice formats are recommended by Swiss authorities for e-invoicing. Additionally, the QR-Rechnung is the mandatory format for payment slips used in Switzerland.
Archiving
What are the archiving requirements in Switzerland?
Invoices must be stored for 10 years using technical procedures that guarantee document integrity. A time stamp must also be applied as proof of the storage date.
Legal invoice:
- For suppliers: The legal invoice is the invoice sent to the recipient, in the format in which it is received. If sent via email, the email is considered part of the legal invoice.
- For buyers: The legal invoice is the invoice received from the supplier, in the format in which it was sent. If sent via email, the email is considered part of the legal invoice.
