Enhancing AP Efficiency by Converting KSeF XML Invoices into Readable Format

Under Poland's KSeF e-invoicing mandate, the legally valid invoice format is XML. All inbound invoices from in-scope taxpayers are delivered exclusively in structured XML format through the KSeF system. From 1 February 2026, organizations must therefore receive invoices through KSeF even if they were not yet issuing invoices via the platform.

Challenge

While XML ensures structured reporting and regulatory compliance, it is not user-friendly for business users. Accounts Payable teams must access XML-based invoices, interpret invoice information such as amounts, VAT details, and supplier data, create vendor invoice postings in SAP, and perform verification and approval workflows. Processing raw XML files created significant operational challenges for the AP team. Although legally compliant, the format was not practical for daily business operations.

  • Reduced productivity
  • Increased manual handling time
  • Risk of misinterpretation
  • Disruption of established invoice processing routines

KGT's Solution

KGT designed and implemented a structured transformation layer that converts incoming KSeF XML invoices into a fully readable format. The solution transforms XML invoice data into a clear human-readable layout, generates a structured PDF view for AP users, preserves all legally required XML data fields, and ensures full alignment with the original KSeF submission. With this approach, AP users can view invoices in a familiar visual format, access invoice details clearly structured, continue using existing workflows such as OCR and SAP VIM processing, and avoid manual interaction with raw XML files. The transformation enhances usability while maintaining the legally required XML format.
