ZUGFeRD invoice
Is it possible to generate ZUGFeRD invoices and send them via Universal Email?
ZUGFeRD invoices are a type of digital invoice format developed in Germany, aimed at standardizing the exchange of invoice data across various industries. This format integrates structured data (in XML format) and human-readable content (typically a PDF) into a single file, which can be read by accounting software.
Alternatively, can an XML file of an invoice be generated and attached to an email.
