E-Invoicing is currently accepted, as well as paper or PDF invoices.
E-Invoicing should become mandatory both for B2G & B2B transactions in 2026 through the “KSeF” central platform using the “FA(2)” (XML) format, although the project has been postponed and currently sits at a standstill.
The existing “PEF” platform, connected to Peppol, will also remain available for B2G transactions using the Peppol BIS 3.0 format.
