XML Schemas

The OPENTRANS and xRechnung are an XML file that contain all data of the invoice in a standardized form as text. This is needed on the one hand by the e-mail provider XimantiX, where e.g. for the postage of a Letter Store order the country code is important, and on the other hand by the recipient ERP system, where then no longer the PDF has to be analyzed, but simply the data can be read out from the XML.

With the +New button you can simply create your own XML schema as well. On the General tab you can define your XML schema and in Lines tab you can choose and manage your parameters.

Fields​

  • Code Specifies the value of the Code field.
  • Document Type Specifies the value of the Document Type field.
  • Description Specifies the value of the Description field.

What's New (January 2026)​

  • Invoice Notes Blob support: Header notes now populate the "Invoice Notes Blob" field, allowing schemas to stream longer text without truncation.
  • Reusable note builder: The schema system uses a shared helper to collect invoice and credit memo notes, ensuring identical output across XRechnung and UBL exports.
  • Text-mode blob rendering: Schema lines can point to blob sources and mark the format as text so that the XML writer emits readable strings instead of Base64.
