No registration is required; processing is GDPR-compliant and files are deleted after validation.

Question 2

What is XRechnung?

Accepted Answer

XRechnung is the German standard for structured electronic invoices (e-invoices), based on the European EN16931 norm. It defines XML rules and business rules (e.g. BR-DE) used for B2B and B2G invoicing in Germany.

Question 3

What is ZUGFeRD?

Accepted Answer

ZUGFeRD is a hybrid e-invoice format that combines a human-readable PDF with an embedded XML invoice (XRechnung-compliant). It is widely used in German-speaking countries for electronic invoicing.

Question 4

How do I validate an XRechnung or ZUGFeRD invoice?

Accepted Answer

Upload your XRechnung XML or ZUGFeRD PDF at edocuportal.com/tools/e-rechnung-validator. The tool checks the file against official KoSIT rules and EN16931 and shows passed checks and any errors with explanations. Files are deleted after processing.

Question 5

What are BR-DE validation errors?

Accepted Answer

BR-DE errors are German e-invoice business rules defined by KoSIT for XRechnung. They cover payment details, contact data, tax IDs, IBAN format, and other mandatory or conditional fields. eDocuPortal provides a searchable error library with causes and fixes for each code.

Question 6

What is a USt-IdNr. (VAT ID)?

Accepted Answer

The USt-IdNr. (Umsatzsteuer-Identifikationsnummer) is the EU VAT identification number used for intra-community B2B trade and on invoices. It consists of a country code (e.g. DE, AT) and a country-specific digit sequence with a check digit. eDocuPortal offers a free technical checker for format and checksum for multiple EU countries.

Question 7

What is the difference between Steuernummer and USt-IdNr.?

Accepted Answer

Steuernummer is the national tax number assigned by the German tax office for all tax matters. USt-IdNr. (VAT ID) is an EU-wide number used specifically for VAT and intra-community supplies. Use Steuernummer for domestic German tax; use USt-IdNr. on invoices for B2B supplies to other EU countries.
