What is Mercurius?

Mercurius is the software platform that Belgian government agencies use to receive and process e-invoices and other documents in UBL format. Just like the Billit invoicing platform, it is connected to a certified PEPPOL access point. To send invoices to a Belgian government agency, you must send it from a PEPPOL access point to which you have access to the access point with which the Mercurius platform is connected.

How do I send an invoice to the Mercurius platform?

Billit has its own certified access point, making it very easy to send invoices to a government agency. All you need is the company registration number or GLN number of the government agency that you want to invoice, as well as the department’s PO number, and a free* Billit account. You can find a step-by-step guide for sending e-invoices to government agencies or other companies that are connected to the PEPPOL network here.
(*You can test Billit for free for 15 days, after that Billit’s free version only allows you to create and send e-invoices. If you need more options, take out a subscription customised for your company)
