Frequently asked

What people ask us about signatures

Is it legally valid?
Yes. A qualified electronic signature carries the same legal weight as a handwritten signature under EU Regulation 910/2014 (eIDAS), across the entire European Union, including in dealings with public institutions.
How long does it take to obtain?
Usually one or two working days. We guide you through the identity verification step and handle the full configuration on your devices.
Can I file tax documents with it?
Yes. The qualified certificate is exactly what accountants use for submitting tax filings. We also configure it for e-invoicing and public procurement portals if you need that.
What happens when it expires?
Certificates are issued for one to three years. We notify you well before expiry and handle the renewal, so you are never left unable to sign.
