E-invoice and digital transformation

Definition of e-invoice

The e-invoice is the first step in the digital transformation. The definition of an e-invoice is an invoice that has been produced digitally and transported electronically. This means that an email with a PDF that displays an image of an invoice is an electronic invoice. For a company that processes its invoices automatically, it makes no difference whether it needs to scan an image from an email or an invoice on paper.


In the times of the DSGVO it is at least questionable to send invoices by email, apart from that it also seems questionable if companies protect their trade secrets such as suppliers, customers, product prices, purchase prices, conditions and more from public access via firewall in order to write the same information into a publicly accessible email system. The complete e-invoice process starts with the document creation. We help our customers to convert their suppliers to structured e-invoices. Invoicing costs for suppliers are reduced by more than 90% compared to paper, and the cost of invoice processing for our customers tends towards zero. For a company that processes its invoices automatically, it makes no difference whether it needs to scan an image from an email or an invoice on paper.

Only one of these invoices is smart!

Structured invoice.

PDFs with embedded XML do not require coordination with the customer. The PDF can be processed as usual or the XML can be read by most ERP and accounting systems without errors.

ZOOM Testrechnung

Image based invoice.

Searchable PDFs are still the exception as the rule. In most cases, the invoices with OCR procedures have to convert the images into text, which of course is not without errors.

In times of digital transformation, most invoices are still images of invoices. No matter whether images on paper or images in a PDF, both variants must be digitized at great cost in order to capture the data digitally.
