PDF and e-invoice (UBL)

Every invoice comes as a PDF for people and an e-invoice (UBL) for accounting software.

PDF

• In the editor you see the PDF as you type. A draft has a "DRAFT" watermark and is called concept-….pdf.
• Download a finalised invoice via Download PDF. It's called factuur-2026-0001.pdf, a credit note creditnota-C2026-0001.pdf.
• The PDF has the layout you had when you finalised it. If you change your house style later, the PDF of a finalised invoice doesn't change.
• The language follows the invoice language: Dutch, English, German or French.

E-invoice (UBL)

An e-invoice is an XML file that accounting software (such as Moneybird, Exact, Twinfield, e-Boekhouden or Snelstart) reads without retyping. EenFactuurMaken.nl produces UBL 2.1 following Peppol BIS Billing 3.0 with the Dutch rules (NLCIUS). A credit note becomes a UBL CreditNote.

• Download it via Download UBL (Peppol). The file is called invoice-2026-0001.xml.
• Only finalised invoices have a UBL. For a draft you get invoice_not_issued.
• The VAT treatment is encoded correctly, with the right VAT category: S (standard), AE (reverse charge), K (intra-EU goods), G (export of goods), O (outside the scope), E (exempt and KOR).

When is there no UBL?

• No KvK number. If you're not registered in the Handelsregister, the Dutch Peppol profile isn't possible. You get peppol_kvk_required. The PDF works as usual. See Business details.
• Customer without an electronic address. When we email the invoice, we only attach the UBL if your customer has a Peppol ID, KvK number or EU VAT number. Individuals only get the PDF. You can always download it yourself.

Peppol

Peppol is the European network for e-invoices. EenFactuurMaken.nl creates files in the Peppol format, but doesn't send them over the Peppol network itself. Does your customer want to receive invoices via Peppol? Then upload the UBL to their accounting software or Peppol provider. Enter your own Peppol ID in your business details and your customer's on the customer.

PDF with embedded UBL

The PDF your customer downloads from the online invoice has the UBL embedded. That gives them one file for people and machines. Through the API you request it with GET /api/v1/invoices/{id}/pdf?embedUbl=1, and a UBL with the PDF inside with GET /api/v1/invoices/{id}/ubl?embedPdf=1.

Downloading and retention

On the Free plan we keep your invoices for 60 days. So download them. An invoice you downloaded (PDF or UBL) or exported in a ZIP is remembered as downloaded. See Storage and retention and Export (ZIP).
