Question 1

What is a UBL invoice?

Accepted Answer

UBL (Universal Business Language) is an XML-based international standard for electronic invoices and business documents. It's widely used in Peppol networks across Europe and globally for B2B and B2G transactions. UBL invoices contain structured data that can be automatically processed by accounting systems.

Question 2

How do I use the UBL invoice previewer?

Accepted Answer

Simply upload your UBL XML file or paste the XML content into the text area. The previewer will automatically parse and display your invoice in a clean, professional format. You can then print or save the invoice. No account or registration is required.

Question 3

Is this tool completely free?

Accepted Answer

Yes! The UBL invoice previewer is 100% free to use with no limitations. There are no hidden fees, no account required, and no credit card needed. All processing happens directly in your browser for maximum security and privacy.

Question 4

Is my invoice data secure?

Accepted Answer

Absolutely. All XML parsing and preview generation happens entirely in your browser using client-side JavaScript. Your invoice data never leaves your device and is not sent to any server. Once you close the page, all data is immediately cleared from memory.

Question 5

What UBL formats are supported?

Accepted Answer

The previewer supports UBL 2.0, UBL 2.1, and Peppol BIS formats. It handles various namespace configurations and can parse invoices from different accounting systems and e-invoicing platforms including Yuki, Exact, Odoo, SAP, and others.

Question 6

Can I convert my UBL invoice to PDF?

Accepted Answer

Yes! After previewing your invoice, you can use the Print button to print the invoice or save it as a PDF using your browser's 'Print to PDF' feature. The print layout is optimized to create professional-looking PDF invoices.

Question 7

Why would I need to preview a UBL invoice?

Accepted Answer

UBL invoices are XML files that aren't easily readable by humans. This tool converts the structured XML data into a clear, professional invoice layout that you can review, verify, or share with stakeholders. It's useful for accountants, bookkeepers, business owners, and anyone dealing with electronic invoicing.

Question 8

What if my UBL file doesn't load?

Accepted Answer

Make sure your file is a valid UBL invoice XML (not a PDF or other format). Check that the file size is under 5MB. If problems persist, try pasting the XML content directly instead of uploading. The tool supports standard UBL formats - if you have a custom or non-standard format, it may not parse correctly.
