Frequently asked questions about e-invoices (FAQ)
What is an e-invoice (EN 16931)?
An e-invoice is an invoice whose data is transmitted in a structured, machine-readable format based on the
European standard EN 16931 - not just a scanned or printed PDF. Common formats are Factur-X/ZUGFeRD (a PDF with
embedded XML data) and XRechnung or UBL invoices (pure XML files). Automatic X-Invoice Processor reads all of these
formats automatically.
What is the difference between Factur-X/ZUGFeRD and XRechnung?
Factur-X and ZUGFeRD are hybrid formats: a regular PDF invoice with the structured XML invoice data embedded in it,
so the document can be opened and read as usual. An XRechnung, by contrast, consists of XML only, without a PDF view.
Automatic X-Invoice Processor processes both variants in all common versions automatically and applies the same rules to them.
How can I open and read an XML e-invoice?
Without additional software, Windows only displays an XML invoice as raw XML source code. Automatic X-Invoice Processor
automatically converts incoming XML invoices into readable PDFs or prints them graphically rendered - like a classic
invoice with sender, line items, and totals. See the step-by-step guide
How to convert e-invoices to readable PDFs.
Do I need to keep the XML original?
Yes. The readable PDF rendering is intended for checking, approval, and everyday filing - the structured XML file remains
the authoritative original and should be archived alongside it. Automatic X-Invoice Processor can store both together in a
structured folder hierarchy automatically.
How can I automate my e-invoice intake?
Let Automatic X-Invoice Processor monitor the folders where your e-invoices arrive - for example, an email attachment folder,
a scan folder, or a portal download folder. Incoming invoices are then renamed, converted, archived, and their data extracted
automatically according to your rules - try it free for 30 days.
