KSeF (Krajowy System e-Faktur) is a free government system for issuing and receiving structured invoices. It requires manual handling and offers no workflow or automation features.
getsix® Invoice Portal is a tool (application) that automates KSeF document handling, organises processes, and enables document control. The subscription covers: use of the application, the integration, technical maintenance, support, and ongoing adaptation to KSeF regulatory changes. The fee does not relate to KSeF — only to the solution built on top of it.
