Poland’s KSeF platform has been live in production since January 2022, allowing businesses in Poland to issue invoices electronically with structured data. Each invoice issued through KSeF is assigned a unique number which signifies that it has been formally introduced into legal circulation. While use of KSeF is currently voluntary, all Polish businesses will be mandated to issue e-invoices to their customers via the platform from July 1, 2024.
