Mercurius

Mercurius is the Belgian federal government's central e-invoicing platform, serving as the receiving hub for all Peppol e-invoices sent to federal public services. Suppliers to the Belgian government are required to send their invoices electronically via Peppol, and Mercurius handles the reception, validation, and routing of these documents to the appropriate government departments. The platform is operated by BOSA and is a key component of Belgium's e-procurement infrastructure.
