Invoicing over Peppol: what changed for freelancers
Since January 2026, invoices between VAT-registered businesses in Belgium travel as structured files over the Peppol network. The PDF attached to an email has not disappeared from your life, but between professionals it is no longer enough.
A structured invoice is not a PDF
A PDF is made to be read by a human. A structured invoice is a file your client's accounting software reads directly: the number, the date, the client, every line, the VAT. Nothing is re-typed, so nothing is re-typed wrong.
In practice, your client no longer "receives" your invoice in an inbox where it gets lost between two newsletters: it lands inside their tool, ready to be processed.
What you have to check on your side
Three things, and they are settled once:
- Be reachable on the network. A Peppol invoice goes to a business electronic address, not to an email address. Your company has to be registered with an access point for that address to exist at all.
- Know the client's identifier. In most cases it is their enterprise or VAT number. If they are not reachable, the invoice will not go out — better to find that out before the due date than after.
- Keep your data clean. A wrong VAT number blocks the send. Annoying at the time, far less annoying than an invoice everyone agrees was never received.
Receiving is the other half of the job
Sending comes to mind first, because it is what triggers payment. But your suppliers send theirs the same way. With nothing to receive them, they land nowhere, and you discover at the end of the quarter that deductible costs slipped past you.
An inbox that gathers what comes in is worth as much as the button that sends things out.
What it does not change
Nothing forces you to invoice faster, or differently. The legal content of an invoice is the same, the mandatory mentions too, and a sent invoice still commits you.
What changes is the channel — and how much re-typing it removes on both sides.
