Domestic (Polish) suppliers: please issue invoices only in KSeF, the Polish national e-invoicing system; the buyer identifier is NIP 5252838136. An invoice is deemed delivered once it receives its KSeF number – there is no need to send it separately.
International suppliers: a PDF file sent to the email address specified in the contract or purchase order.
Paper invoices: to the registered office address.
Each invoice is required to show the Danske Gas contract or order number and, for goods listed in Annex 15 to the Polish VAT Act (including fuels), also the note ‘mechanizm podzielonej płatności’ (split payment mechanism). The bank account on the invoice must match the contract and be in the Polish VAT taxpayer register (the ‘white list’).
The payment term runs from the day we receive an invoice meeting the requirements above. If the contract or order number is missing, or the account is outside the register, we send the invoice back with a request for correction – the term then runs from delivery of the corrected invoice.
Credit notes and correcting invoices: state the number and date of the original invoice and the reason for the correction.
