  2. If you issued the invoice yourself: attach supporting documents as PDF and check that your software declares the file type correctly.

Message to the sender

Subject: Invoice {invoiceNumber} – attachment file type not allowed

Hello,

Thank you for your invoice {invoiceNumber} dated {issueDate}. When checking it we noticed that one attachment has a file type that is not allowed in an XRechnung (rule BR-DEX-01). Allowed types include PDF, PNG, JPEG and CSV. Could you please send the invoice again with the attachment in an allowed format?

Kind regards

Example

An embedded ZIP archive labelled application/zip triggers the rule. The sender exports the supporting document as a PDF and embeds that PDF with application/pdf.
