Sent via the Peppol network
Is Peppol mandatory?
Yes. Since 1 January 2026, e-invoicing via Peppol is mandatory for all Belgian invoices to business (B2B) clients. Invoices to private clients are not included, and neither are invoices to Dutch businesses or consumers.
Do I need Peppol for all my clients?
No. Only invoices to Belgian business clients go via Peppol. Invoices to private clients are sent as usual.
Can I keep working the way I do now?
Yes. You create invoices as usual, and Trainin sends them via Peppol in the background.
How do I switch on Peppol?
Send an email to support@trainin.com and we'll activate Peppol in your Trainin account.
What does Peppol via Trainin cost?
The Peppol add-on costs €9 per month (excl. VAT), and you can cancel it monthly.
How do I see whether an invoice was processed?
You see the status of every e-invoice in your Trainin account.
