Archiving electronic invoices
E-invoice archiving – automated and searchable
Archiving of e-invoices
E-invoices such as ZUGFeRD or XRechnung are not ordinary PDF files, but structured XML documents whose content must be machine-readable and stored unchanged. For companies, this means that not only the readability but also the technical integrity of the XML data must be ensured – for the entire statutory retention period.
REDDOXX offers the right solution for this: structured invoice formats are automatically recognized, classified and archived with all metadata upon receipt of the e-mail – audit-proof, searchable and graphically prepared.

ZUGFeRD and XRechnung invoices are archived with all XML content and can be filtered directly – ideal for accounting and auditing processes.

Use your own search mask with preview view, structured data extraction and visual representation of the invoice.

All invoice data is archived in an unalterable, traceable and chronological manner – including XML integrity and retention periods.

E-invoices are automatically recognized and archived – regardless of whether they are received via Microsoft 365 or a local mail server.

REDDOXX recognizes and archives structured invoice formats such as ZUGFeRD and XRechnung automatically, without any manual effort.

Archived invoice data can be exported, filtered or checked directly – the ideal interface to the tax office or ERP solution.
Archiving of e-invoices
With the increasing spread of e-invoices, the requirements for archiving them are also increasing. REDDOXX takes this task off your hands completely: structured XML invoices are automatically recognized when they are received by e-mail, saved unalterably and made conveniently searchable via a specially developed interface – ideal for accounting, tax audits and digital workflows.

Automatic recognition and archiving of e-invoices
REDDOXX automatically recognizes incoming electronic invoices in ZUGFeRD or XRechnung format, regardless of which mail server they were received via. The structured XML file and email are archived in an audit-proof manner – unalterable, traceable and legally compliant.
And the best thing is that the configuration is completed in 5 minutes and the system works completely in the background.
Specialized search and filter functions for structured invoice data
In the REDDOXX archive, e-invoices can be found using special filters and search criteria. In addition to classic parameters such as sender or subject, structured invoice data (e.g. invoice number, amount or recipient) can also be searched and evaluated.
And best of all, the associated XML file is not only archived, but also visually processed, including a graphical preview directly in the web portal.
