Questions about e-invoicing in Belgium

Do I have to use a government platform?
No. Belgium uses the Peppol network, and the government has said it won’t offer a central application of its own. You choose your own accounting software or Peppol provider.
Who doesn’t have to send e-invoices?
According to the official FAQ: bankrupt businesses, businesses that only carry out VAT-exempt activities (Article 44), businesses not established in Belgium, and businesses under the flat-rate scheme (Article 56) until it ends. Bankrupt businesses and those under the flat-rate scheme must still be able to receive them. Our “Do I need it?” check walks you through your own case.
Which format is used?
Peppol BIS Billing 3.0, unless both sides agree on another format that follows the European standard EN 16931.
