FAQ

Common questions

What is KSeF?

KSeF (Krajowy System e-Faktur) is Poland's national e-invoicing system, operated by Poland's tax administration, for issuing and receiving structured invoices.

When is KSeF mandatory in Poland?

KSeF mandate dates have shifted multiple times. Treat any specific go-live date you see elsewhere as unconfirmed until checked against the current official timeline from Poland's tax administration.

Does Invogi validate KSeF invoices?

Format validation is handled by Invogi's compliance adapter once a profile has been independently verified against reference fixtures — see the compliance overview for how we treat profile support claims.
