Understand this route
Issue invoices with regard to VAT documentation and current KSeF applicability.
What to do
1. Determine the transaction type, VAT status and whether KSeF is required.
2. Keep the invoice and confirmation in the form required for your records.
Core invoice data
Check seller identification and, where required, buyer identification; a unique number, issue date, supply/service date where different, description, quantity and value, VAT rate and amount where applicable, and the gross/total amount. A VAT invoice, a consumer document and a KSeF technical format are not the same question.
Corrections, KSeF and records
Correct an error using the applicable correction document. Check the current mandatory-KSeF phase separately in the KSeF route; after issue, retain/deliver the document by the applicable method and reflect it in the applicable records and JPK.
