/ How to connect EDI with the National e-Invoice System (KSeF) in Poland?

EDI systems may still be used, but each invoice transmitted outside National e-Invoice System (KSeF) must include a QR code or link for verification in the system. It can be added directly to the EDI file or sent together with the invoice – e.g. in the same email or EDI message. “Together with the invoice” means in the same data package, not necessarily the same file.
