• Only invoices can be processed with .pdf format
• These must not be write-protected (password protected)
• Each .pdf document must only contain one invoice
• Several .pdf invoices can be attached to a single e-mail
• Any other attached file formats as well as the content of the e-mail itself are not considered and are thus not processed further
