What to know about e-invoicing in Belgium

What matters for you as a freelancer

• ✓A domestic B2B e-invoicing mandate is already live in this country — a plain PDF invoice may no longer be sufficient for local B2B transactions.
• ✓This requires a technical integration (Peppol network registration or a qualified electronic signature) that Agency OS is actively building.

What you don't need to worry about

• –This only applies when both you and your client are based in this country — cross-border invoices aren't affected yet.
• –You don't need to solve this yourself — we'll notify Agency OS users here once support ships.

What must be on a valid B2B invoice

• ·Issue date and a unique, sequential invoice number
• ·Your VAT number and the customer's VAT number (B2B)
• ·Name and address of both parties
• ·Description, quantity, and unit price of goods or services
• ·Delivery date
• ·VAT rate and amount, and the total including VAT
