itdatex E-Invoice Intake

Since 1 January 2025, all businesses in Germany must be able to receive electronic invoices (e-invoices) under § 14 UStG. By 2027/2028 they must also issue them. Most existing tools require uploading sensitive supplier data — amounts, VAT IDs, bank details — to a third-party cloud service. itdatex E-Invoice Intake does the work locally inside your own WordPress installation.

What it does

• Accepts XRechnung (UBL and UN/CEFACT/CII), ZUGFeRD (hybrid PDF/A-3 with embedded XML) and Factur-X via drag-and-drop upload
• Detects the format automatically and parses the core fields: invoice number, dates, seller and buyer, VAT ID, totals (net/tax/gross), positions, buyer reference (Leitweg-ID)
• Validates against the embedded EN-16931 XML schema and checks for required fields (BT-1, BT-2, BT-27, BT-112)
• Stores each file with a random name in a protected upload directory and chains every file’s SHA-256 with the previous one (revision-evidence)
• Provides a human-readable single-invoice view with header data, parties, amounts, validation issues and an audit trail
• Logs every action (upload, status change, download) in a dedicated audit table

Privacy by design

The free version performs all processing locally on your own server. No data leaves your WordPress installation. There is no telemetry, no automatic update check against a third party, no analytics, no external font or asset loading.

A separate Pro version (sold via wp.itdatex.support, not part of this free plugin) adds optional cloud-assisted features — KoSIT deep validation, AI-based error explanations in plain German, IMAP auto-import, DATEV export — and is opt-in only.

GoBD-supporting, not GoBD-certified

The plugin supports GoBD-conformant processes through immutable storage, SHA-256 hash chaining and a complete audit trail. Note that software cannot be “GoBD-certified” — conformity is a property of your process, not of any single tool. Consult your tax advisor for the specifics of your setup.

Open source

The full source code is released under GPL-2.0-or-later. You can verify, audit and adapt the plugin yourself. Dependencies (josemmo/einvoicing for UBL, horstoeko/zugferd for CII/ZUGFeRD) are vendored with prefixed namespaces so they cannot conflict with other plugins in the same WordPress installation.
