The XRechnung XML data set must be viewed by the invoice recipient for further processing. Usually, the data set is viewed within the (ERP) system. KoSIT also offers a corresponding viewing component. The components to support viewing within a system are publicly available in the XRechnung GitHub.
If the invoice cannot be processed in a system-supported and automated way, the use of a viewing solution is recommended in order to better ‘detect’ potential errors.
Invoice issuers/senders also need to be able to view the original invoice – the XML data set – to complete accounting processes. The functionality can be integrated in the electronic outgoing invoice system or ensured via a dedicated viewing solution.
