- In 2026, Poland will implement the mandatory use of the National e-Invoice System (KSeF), replacing traditional paper and PDF invoices with structured XML invoices. These invoices will have a uniform data structure defined by the Ministry of Finance, ensuring consistency and automation in document circulation. Invoices outside the KSeF system must include a verification code, often a QR code. The XML file will contain essential transaction details, such as seller and buyer information, transaction dates, item descriptions, VAT rates, and totals. The system assigns a unique KSeF identification number and timestamp upon submission, marking the invoice as officially issued and delivered. While the XML file is the official document, accounting systems can generate a readable table-like preview or a PDF visualization for informational purposes.
