UBL invoice viewer

Got an .xml file instead of an invoice? Drop it below. You'll see a readable invoice straight away: supplier, customer, lines, VAT, totals and payment details. The file is read in your browser and never uploaded.

Which files can you open?

• SI-UBL 2.0, the Dutch version of the European standard (the NLCIUS), and Peppol BIS Billing 3.0. Dutch Peppol access points must support both ^[1]. Both are UBL 2.1 invoices under EN 16931, so the viewer shows them the same way.
• Credit notes in UBL.
• CII files (UN/CEFACT), such as German XRechnung.

Why did I get an XML file?

An e-invoice isn't a PDF but a structured file that software processes automatically; a PDF sent by email is not an e-invoice ^[2]. Your accounting software normally shows it as an invoice. You only see the raw XML when you download it, when a supplier forwards it, or when your bookkeeper sends it to you.

From 1 July 2030 the government plans to make e-invoices between businesses mandatory, using only the European standard EN 16931 ^[3]. More XML invoices will reach small businesses then.

What the viewer doesn't do

• It doesn't validate. It shows what is in the file. It doesn't tell you whether the invoice passes the SI-UBL 2.0 (NLCIUS) or Peppol BIS rules, or the Basisfactuur Rijk requirements of central government. For what common rule codes (such as BR-CO-15) mean, see validation errors explained. The Dutch Peppol Authority's test tool validates documents ^[1].
• It doesn't create, edit or send invoices. For that you need Peppol software: see free e-invoicing.
• It doesn't archive. The display only helps you read the file; keep the original. You must be able to guarantee the origin, content and legibility of a digital invoice ^[4].

Who sent this file?

Want to know which Peppol provider a supplier or customer uses? Use the Peppol ID lookup with their KvK number or VAT ID. That's a separate click; your invoice file is not sent anywhere.
