- KSeF (National e-Invoice System) is used for issuing and receiving structured invoices, which are not standard PDFs but documents in a specific logical format.
- Only authorized individuals can issue invoices in KSeF; sole proprietors can do this directly, while companies must first set up access and assign permissions.
- Before issuing an invoice, companies must ensure they have access to KSeF using methods like trusted profile, qualified signature, or KSeF certificate.
- All necessary transaction data must be prepared and entered according to KSeF’s logical schema, but invoicing software simplifies this process for users.
- The system validates the technical structure of the invoice automatically after data entry.
