What is it?
An application certificate (.p12) signs fiscal invoices and authenticates to the Tax Administration. Issued by FINA or Certilia.
How to get it online
Request online (FINA), sign, pay, and receive it. The production certificate is valid 5 years; a free demo certificate (1 year) exists for testing.
Needed for e-invoice?
The certificate is required for B2C fiscalization. E-invoices are signed/sent via the intermediary. Upload it once into Fiskalizator; it stays encrypted.
