As a Belgian company, how do I send an invoice to Poland?
If you are a Belgian company doing business with a Polish company, you must invoice according to Belgian rules. In Belgium, the Peppol network is the standard.
To send e-invoices, you must register through a certified Peppol Access Point such as Nymus. Both sole proprietors, and multinationals can use the Peppol network. The choice of a Peppol Access Point is not trivial and depends heavily on your business needs. Do you opt for a Peppol button in your ERP or billing package, or do you opt for an e-service provider that completely unburdens you?
