In Switzerland, the use of a corporate seal or stamp is not mandatory and has no legal value. However, it is commonly used on invoices, quotes, and official correspondence to enhance professionalism. Some countries require a seal to validate commercial documents, which can be useful for Swiss companies operating internationally. There are various types of stamps, including ink stamps, embossed seals, and digital stamps. With digitalization, certified electronic signatures have become a more efficient and legally recognized alternative.
