KSeF – information about e-Invoices
From 1st April 2026, our company will issue invoices exclusively via the National e-Invoice System (KSeF). Below, we present key information regarding the method of issuing and receiving documents.
What is changing
Sales invoices and their corrections are issued exclusively in the KSeF system.
KSeF is the primary channel for document sharing.
The moment of receiving an invoice is the date of assignment of an identifying number in the KSeF system.
Access to invoices
The submission of invoices in PDF format will be gradually restricted.
Ultimately, invoice communication will take place exclusively via KSeF (unless otherwise agreed individually).
Foreign contractors
Foreign contractors not obliged to use KSeF receive invoices on the current terms.
The authenticity of the documents is further confirmed by a QR code placed on the invoice.
What needs to be done
Verify KSeF system access
Ensure that the individuals responsible for accounting have the appropriate permissions
