Flagship service
KSeF 2.0 — we invoice in it every day. Also for our clients.
KSeF has been mandatory in Poland since 1 February 2026 for the largest taxpayers and since 1 April 2026 for the rest. Profais has issued its own invoices through KSeF since 1 February 2026, before the obligation applied to us, and handles its clients' invoices as part of bookkeeping.
