SIGNATURES AND KSEF
Qualified signatures, seals and KSeF certificates
Not every certificate used with KSeF is a qualified signature. Separate authentication, permissions and the role of the KSeF certificate.
Discuss your requestPrepare the context.
Keep documents private.
- Qualified signature: a person.
- Qualified seal: an organisation.
- KSeF certificate: a tool for KSeF.
Start with the person and system
Establish who will use KSeF and which accounting application they use. A sole trader, a company and an employee acting for an organisation can have different access needs.
A KSeF certificate has a specific purpose
The Ministry of Finance distinguishes certificates for authentication and for offline modes. They are system-specific certificates, not a general substitute for qualified signatures on arbitrary documents.
The tool does not grant all permissions
Possessing a signature or seal does not by itself establish the right to act for an organisation. Confirm permissions against current KSeF guidance and with the person responsible in the organisation.
How I can help
I can help identify the need for a signature or seal and agree its service scope. Accounting software configuration and tax matters require separate arrangements with your software provider or accounting adviser.
