E-invoice inbox and outboxTRAFFIQX E-Invoice Exchange
Send e-invoices from web processes, receive incoming invoices and trace delivery status.
This exchange module extends Web2DATEV with structured e-invoice sending and receiving through the TRAFFIQX Invoice API. XRechnung is handled as UBL or CII XML with a PDF view, while ZUGFeRD is handled as a hybrid PDF. Original document, validation status, delivery route and timestamp remain visible in the process.
A good fit when
A defined use case instead of a universal connector
- E-invoices should be sent directly from a website or portal process
- Incoming and outgoing e-invoices need one controlled workflow
- Delivery route, status and original must remain technically traceable
- The Core data route and professional invoice rules are already defined
