Transaction Confirmation in KSeF: Voluntary Option and Documents for ONLINE, OFFLINE, and Emergency Modes

• Issuing a “transaction confirmation” for invoices in KSeF (National e-Invoicing System) is a completely voluntary option, not regulated by law.
• This confirmation can be provided after issuing an invoice in ONLINE, OFFLINE, or emergency modes in KSeF.
• The confirmation is not considered an invoice or a simplified invoice under VAT law.
• It is intended to meet taxpayer needs, especially in situations where the official KSeF invoice number is not yet available.
• The confirmation may include QR codes for access and verification of invoice data.
