In Portugal, tax authorities require resident businesses that offer products or services to government bodies to issue an electronic invoice.
GS1 standards create a common foundation for business by uniquely identifying, accurately capturing, and automatically sharing vital information about products, locations, assets, and more. Businesses can also combine different GS1 standards to streamline business processes such as traceability.
