E-invoicing, done right — in your country.

An e-invoice carries the invoice as structured data your customer’s software reads — not just a picture of it. UNENO Invoice issues it in the format your country asks for, to the European standard EN 16931, and checks it before it goes out.

  • The right format for your country — picked automatically
  • EN 16931, checked before the invoice is issued
  • Included in every plan, at no extra cost
The basics

What makes an invoice electronic.

  • Structured data

    The invoice as data — seller, buyer, lines, VAT — that accounting software reads without anyone typing it. A plain PDF is not an e-invoice.

  • One European standard

    EN 16931 sets what an e-invoice contains. Every country builds on it — with its own formats, channels and dates.

  • Two kinds of file

    A PDF with the data embedded (ZUGFeRD, Factur-X), readable by people and software — or pure XML (XRechnung), for systems.

By country

Your country, your rules.

Dates, formats and channels differ from country to country — each one has its own page.

What Invoice does wherever you are.

  • The format, picked for you

    From the customer, when the invoice is issued — you never choose a format, and customers outside the rules keep getting a plain PDF.

  • Checked before it’s issued

    Against the format’s rules: anything missing is listed, nothing goes out, no number is used.

  • Fixed at issue

    The Format column shows every invoice’s format — switching e-invoicing off later changes none of them.

  • Cancellations too

    Cancelling an e-invoice? The cancellation is an e-invoice as well — a credit note that references the original.

FAQ

Questions about e-invoicing

Short answers to what people ask us most.

What is an e-invoice?

An invoice in a structured format — seller, buyer, lines and VAT as data — that the recipient’s software can read and process without typing. The European standard EN 16931 sets what it contains; each country adds its formats and rules.

Is a PDF invoice an e-invoice?

A plain PDF is not — it is only a picture of the invoice. ZUGFeRD and Factur-X are PDFs with the invoice data embedded as XML, so they count; XRechnung is pure XML.

Which format do I need?

It depends on your country and your customer: in Germany ZUGFeRD for business customers and XRechnung for public authorities, in France Factur-X for business customers. Invoice picks it from the customer when the invoice is issued — you never choose.

In which countries does UNENO Invoice issue e-invoices?

In Germany and France for now — each with its own page — and more countries are on the way. Customers outside these rules keep getting a plain PDF invoice.

Does e-invoicing cost extra?

No. E-invoicing is included in every plan of Invoice — no add-on, no surcharge.

Can I check an e-invoice I received?

Yes — with our free e-invoice checker, in your browser: it validates an XRechnung or ZUGFeRD file against the official rules, and nothing is uploaded.
