Signing Help in Firmify
We've compiled separate instructions for different signing methods β without leaving the Firmify website. Start with the overview Signing Documents for Company Registration, then choose the topic based on how you will sign.
The final submission to the Trade Register (Π’ΡΡΠ³ΠΎΠ²ΡΠΊΠΈ ΡΠ΅Π³ΠΈΡΡΡΡ) is done through the official portal; Firmify helps you prepare and sign the documents beforehand.
Choose a Method
- Signing a PDF Outside the Platform (Adobe Reader, etc.) β if you selected "Upload Signed PDF" and are signing on a computer with an installed QES (Qualified Electronic Signature) and compatible software.
- Evrotrust in Firmify β if you are using the integration with the Evrotrust mobile app.
- B-Trust, Smart Card, and BISS β if you are signing with a certificate on a card/token and the local BISS service.
