An electronic invoice (or e-invoice) is more than just a digital document: it is not only sent and received electronically, but also automatically processed by software. A PDF invoice sent by email is technically also an electronic invoice, but since it can only be read by humans, it does not fall under the definition of electronic invoicing as used and discussed at GS1 Belgilux.
GS1 Belgilux and e-facturatie
GS1 Belgilux only supports standards for machine-readable EDI invoices. EDI (Electronic Data Interchange) is the electronic exchange of business documents between trading partners. Instead of using traditional methods like paper, fax, or email, EDI enables the automated and secure exchange of essential information, such as purchase orders and invoices, between companies.

E-invoice formats
There are different formats for electronic invoicing via EDI and for other EDI business documents (such as electronic purchase orders or delivery notes). Each industry may have its own specific requirements. At GS1 Belgilux, we support two commonly used formats: Harmonised Order to Cash & Peppol.
