Definition and requirements of an eInvoice

According to the German Value Added Tax Act (UStG), there are specific requirements for a digital invoice as a proper eInvoice is recognized. These requirements serve to ensure the authenticity and integrity of the electronic invoicing and to ensure that the invoice management-processes are legally compliant and efficient.

Electronic creation and dispatch

First of all, a eInvoice be created electronically from scratch and transmitted digitally to the invoice recipient. A merely scanned paper invoice does not fulfill this requirement, as it is not originally created as an invoice. digital invoice was designed.

Readability for people

Furthermore, a eInvoice be human-readable. This means that all relevant information such as invoice amount, service description and payment information must be presented in an easily understandable format, for example as a PDF document or in the ZUGFeRD standard.

Authenticity of origin

To verify the authenticity of the origin of a eInvoice companies must implement internal control procedures. This can be done, for example, by using qualified electronic signatures or by using secure transmission channels.

Integrity of the data

After all, the integrity of the data stored in a eInvoice data must be guaranteed. For this purpose, procedures such as the calculation of a checksum are often used to ensure that the invoice data has not been manipulated during transmission and storage.

Companies that meet these requirements can benefit from the advantages of the invoice digitization such as cost savings, increased efficiency and improved traceability. The use of a professional invoicing software can provide valuable support here.

Standards for eInvoices in Germany

In order to ensure conformity with the generally accepted accounting principles (GoBD) for the electronic invoice processing companies and governments in Germany have worked together to find solutions. As a result of the e-invoicing regulation, two main standards have been established: the XInvoice and ZUGFeRD.


The XInvoice is an XML-based data model that was developed specifically for the Invoice exchange between authorities and governments at European level. This standard enables a smooth Electronic invoicing and -processing within the public sector.


ZUGFeRD on the other hand, is a standard for hybrid invoice data. It combines the advantages of PDF files with machine-readable XML data, whereby online invoices for both humans and automated systems Invoice processes are readable. ZUGFeRD facilitates the Electronic invoicing in the B2B sector and is used by many companies in Germany.

Both standards have proven to be efficient solutions for Invoice processing and are helping to facilitate the transition to mandatory electronic invoicing in Germany.
