Achieving Compliance in Belgium: An overview with mySupply
In Belgium, the online portal Mercurius and the Peppol network are used for document exchange. All Belgian companies are registered in the Peppol network either through the Hermes solution or a Peppol service operator. Hermes ensures that all Belgian companies can receive electronic invoices, either forwarding the incoming invoices as PDFs via email or as actual electronic invoices (XML).
