I patched Typst’s PDF export to create ZUGFeRD e-invoices
ZUGFeRD is a German/European standard for electronic invoices. The commit linked below includes a little hack for PDF/A-3b support and an optional file embedding according to the ZUGFeRD specification.
Hopefully, this kind of file embedding can either be done from inside a Typst file at some point, or the pdf export can get an extension system so that this does not require a fork anymore
Is anyone else here working with Typst for electronic invoices?
