Confirmation of KSeF-Invoiced Transactions: Voluntary Option and Documents for ONLINE, OFFLINE, Emergency Modes

• Issuing a “transaction confirmation” for invoices in KSeF (National e-Invoicing System) is a completely voluntary option, not regulated by law.
• The confirmation can be provided after issuing an invoice in ONLINE, OFFLINE, or emergency modes.
• This confirmation is not a VAT invoice or a simplified invoice and does not create new obligations for taxpayers.
• It is especially useful in situations where the buyer needs proof of transaction before the KSeF number is assigned, such as in retail stores or gas stations.
• The confirmation may include QR codes for access to and verification of the invoice data.
