Sending a sales invoice through Peppol
Check UBL validation and reachability and send through the appropriate Peppol network.
Updated on August 28, 2026
This page checks the electronic invoice files and customer reachability before starting an external Peppol delivery. Use it for a final invoice to a business customer. Peppol must be active for the administration, and sender and customer need the required VAT and Peppol identifiers.
Preparation checks
Billnado gathers the UBL files, checks customer registration and validates the invoice. One or both cards may appear:
| Card | Meaning |
|---|---|
| European Peppol network | Uses the European Peppol identifier and European UBL file. |
| National Peppol network | Uses the national identifier and national UBL file; the customer needs a national VAT number. |
Each card shows file name, creation date, customer reachability and validation state. Wait while UBL is being checked. Valid UBL is eligible for the next checks. For Invalid UBL, review the displayed errors and correct the invoice or relation data. Customer not found means the customer is not registered on that network with the identifier in use.
If Peppol is inactive, choose Go to Peppol integration. If no UBL exists, return to the invoice and wait for document generation or save corrected invoice data again.
Downloading and sending
Download European and Download National save the corresponding UBL for review and do not send it.
Send European or Send National appears only when Peppol is active, the correct UBL exists and is valid, the customer is reachable on that network, and the required identifier is available.
Important: sending has a real external effect. Check invoice number, customer, amounts and network before continuing, and do not repeat the action while it is processing.
After acceptance, the confirmation page opens. Send by email uses the alternative channel; Cancel returns without a Peppol delivery.
