Invoice us We are requiring electronic invoices from our suppliers. An electronic invoice ("e-invoices") needs to have the same contents as a paper invoice. It consists of invoice data fields in XML file and invoice image e.g. in PDF file. An e-invoice can be received directly to our purchase invoice handling system in electronic format which ensures cost-efficient invoice handling process, accurate and timely payments for suppliers as well as smaller carbon footprint.
