The e-invoice is a structured, machine-readable invoice in XML format according to EN 16931. Since January 1, 2025, German companies have been required to be technically able to receive e-invoices. Unlike PDF invoices, it enables automated processing without OCR, reduces data entry errors, and sustainably improves data quality in accounting.
The introduction of mandatory electronic invoice (e-invoice) In the German B2B sector, the change on January 1, 2025, marks a fundamental turning point for the quality of accounting data.
While digital transformation in accounting was long characterized by the automated processing of image-based formats, the transition to structured, machine-readable invoice data now enables true Straight Through Processing (STP).
This step is far more than a regulatory obligation. It forms the technological basis for an error-free and audit-proof database.
E-invoicing in B2B – What’s changing technically?
Until now, the automated capture of digital documents has relied heavily on OCR (Optical Character Recognition) technology. Although modern algorithms achieve recognition rates well over 90%, a PDF remains, from a technological perspective, an unstructured format that must be interpreted by the system and is prone to errors.
With e-invoices compliant with the European standard EN 16931, such as XRechnung or the hybrid ZUGFeRD format, this interpretation step is eliminated. Invoice numbers, tax amounts, and item data are no longer extracted but processed directly as structured XML data records. This significantly reduces system-related transmission and data entry errors.

How does e-invoicing improve data quality?
A key advantage of structured e-invoices lies in their technical auditability. According to the Guidelines of the Federal Ministry of Finance (BMF) A distinction is made between different classes of errors, which can be detected using validation tools.
Format error
These issues result in a document not being legally recognized as an e-invoice because the technical syntax (e.g., XML structure) is faulty.
Business Rule Errors
The system checks for logical dependencies, such as whether mandatory fields like the “Buyer Reference” are present or whether the sum of net and tax amounts is mathematically correct.
This automated quality control ensures that errors are not only discovered during month-end closing, but also at the moment the data is received. GetMyInvoices integrates these validation processes directly into the workflow and ensures that only verified data records are forwarded to ERP or accounting systems.
Completeness as a key quality factor
Even the highest precision in individual documents loses value if the data stream remains incomplete. In an environment where e-invoices arrive via various channels such as email inboxes, online portals, or networks like Peppol, completeness becomes a critical success factor for accounting quality.
Here, GetMyInvoices acts as a central infrastructure that automatically collects invoices and receipts from over 10,000 online portals, email accounts and other sources and reconciles them with bank transactions.
This ensures that the accounting is not only correct, but also complete.
ViDA – The future of the reporting system
The improved data quality is also a strategic preparation for future requirements.
As part of the EU initiative „VAT in the Digital Age“ (ViDA) The introduction of a transaction-related electronic reporting system is currently planned for 2030 onwards.
EU member states that already have a national reporting system have until 2035 to implement it.
Companies that already rely on structured data and GoBD-compliant archiving are investing in a future-proof financial data architecture and will be able to meet these reporting obligations without additional manual effort.
GetMyInvoices supports this process through audit-proof archiving in accordance with GoBD in the original format (XML), which guarantees immutability and readability throughout the entire legal retention period.
The seamless transfer of validated data to systems such as DATEV or other ERP solutions ensures data integrity throughout the entire process.
Conclusion
E-invoicing is fundamentally transforming accounting. Bookkeeping is evolving from a downstream document archive to proactive, quality-assured data management.
Companies that actively shape this paradigm shift benefit from higher data integrity, lower susceptibility to errors, and better auditability.
E-invoicing is more than a legal obligation. It is the technological foundation for a new level of quality in finance.
