• create_zugferd

  Builds a ZUGFeRD 2.x / Factur-X hybrid invoice from the same details create_xrechnung takes, and returns it as a PDF file. A hybrid is one invoice stated twice in one file: a PDF/A-3 document a person reads, carrying the same invoice inside it as EN 16931 XML a machine books. Thi

  Converts between net, tax and gross for a given VAT rate, in either direction. Give an amount and say whether it is net or gross, and you get all three figures back rounded to the cent. Germany's rates are 19 % (standard) and 7 % (reduced), but any rate from 0 to 100 is accepted,

• validate_einvoice

  Reads an existing electronic invoice and reports what is wrong with it. Accepts XRechnung and ZUGFeRD XML in either EN 16931 syntax — CII (used by XRechnung and ZUGFeRD) and UBL — and reports the syntax and profile it found along with the invoice's key fields, so it also answers
